October 2020's donation goal has been met. Thank you for your support!

Hello! Thank you for using yiff.party!

We hope you enjoy using it. yiff.party operates on a non-profit basis, and as such, all the server expenses are paid by our users. We don't want to run ads or infect you with crypto miners. We depend on users like you to keep the site running, and to preserve years and terabytes of amazing content—some of which is no longer available from its original creators!

Because of the nature of the site, many users are reluctant to donate. That's OK! yiff.party was created so everyone can enjoy the content we host without any restrictions or paywalls. But if you value the service we provide, and are able to, we—and our users—would be tremendously grateful if you considered making a donation.

Donation progress for October 2020

So far, approximately $400.00 has been raised out of our target of $400.00. We're about 100% of the way there! Please note: this tracker is updated manually—don't worry if your donation doesn't show up immediately!

yiff.party's server costs are due on the last day of each month. So, we need to meet this goal before 31 October!

How to donate?

At this time, yiff.party can only accept donations in numerous cryptocurrencies. Please select a currency below to display the relevant donation address.

Bitcoin (BTC)
Bitcoin Cash (BCH)
Ethereum (ETH)
Ethereum Classic (ETC)
Litecoin (LTC)
Why can't I donate through other means (eg. PayPal)?

Due to the nature of sites like yiff.party, it is very difficult to find payment processors who will accept clients like us. If we were to accept donations via PayPal, it wouldn't take more than a day for someone to submit an abuse report and get our account frozen. Until a viable way of accepting monetary donations becomes available, cryptocurrency will remain the only option.

There are many resources available on how to purchase crypto. For Bitcoin, check out bitcoin.org's page on buying Bitcoin for a list of methods. For beginner Bitcoin users, yiff.party recommends using an escrow service such as LocalBitcoins.

Very impressive! So many digits, so few PPMs! : ) Unfortunately, I, too, got infected by the volt-nut-bug... But I'm trying to be very, very reasonable and am aiming for the "most economical" 6 1/2 digits for the time being... My best bet right now (in Germany): the old Premas... (big bonus: 6502! big let down: the internal cabling) For the most economical and programmable GPIB adapter you might want to have a look at the https://github.com/Twilight-Logic/AR488 ...

Haven't forgotten and will do soon! But there is one more calibrator thing I need to do within a limited time OSMUpdate is going to look like this: Project has gotten even more ambitious than I started out with. So it's now a team effort, check out the OSMU channel on the discord to participate. The 4-quadrant power output stage I designed and linked before has some minor mistakes, but I think it'll work soon.

Lots of KiCad showing up! Didn't you use EAGLE before? What brought you over? :)

Yeah, EAGLE was okay years ago. Now it feels like 10 new shiny UI layers on top of fundamental code from 1988

Who told you about my proje- oh, right. Hope you enjoy using it!
user avatar
marcoreps - 19 Aug 20 10:01
What, are you involved with EAGLE, KiCAD or iBOM? 😅 I have enjoyed all of them tbh, I think what really made me change to KiCAD is that everybody uses it, so I can share useful project files to go along with YouTube videos. Altium wants to give me a free license for Youtube videos too, but Altium project files would be useful to only very few.
user avatar
User #11988099 - 19 Aug 20 10:29
Nah, I have no part in any of the mentioned. T'was a joke about how my code often is one good piece/idea but covered in a lot of crud. I've seen EEVBlog's Dave use Altium a couple times, and it seems super neat and interesting. However, I (personally) have no need for something like that when KiCad does what I need, plus more, for free.

It got even more ambitious than I originally wanted it to be 😅 It's a team effort now, happening mostly on the discord server. It'll take a lot longer, but it will be worth it. This power output stage is one of multiple candidates we are considering https://github.com/marcoreps/lt1166_bob

User #28976101 - 24 Aug 20 17:06
You could use a two stage design for your amplifier, you can dimension the first stage that even with the worst leakage current of you cap you don't hit the supply rails and then use a second dc block with a higher gain amplifier afterwards that way you won't have that much leakage anyways because you've got a lower dc bias 🤔
user avatar
User #28976101 - 24 Aug 20 17:07
A colleague of mine built a low noise amp which goes down to 1/10Hz and he didn't use any fancy tantalum caps so maybe you can do the same 😉

Context brings a lot of value in content. Seeing people with super expensive solder irons doing very clean joins is impressive, but there's no value there. Seeing you soldering with a Chinese iron, in the wood, while it rains, on a battery pack, might not yield the best looking joins, but it sure give me crucial details on how to manage a good-enough-to-work-on-electronics joins and this, to me, gives me confidence to try something new and harder. But that's just my silly opinion :)

I am showing how to set it up and how to use it somewhat successfully. I am also taking apart a beta version of the printer to show a few of the internal details that make this product special. At the end I am showing some printed results to demonstrate the machines capabilities in geometric accuracy and small feature size.

I suspect that your best bet for a machinable foam would be regular polyurethane closed cell foam plus a CNC hot wire cutter. Most of the machining and prototyping foams of which I am aware are designed for carbon fiber composite layup, and so are intentionally quite stiff. Typically, stiffness and coefficient of thermal expansion are more important for these foams than the insulative properties that you appear to be looking for.

hm yes, PU foam indeed seems to last forever and it was used in the guildline standard cell enclosure (from which I borrowed that mercury thermometer switch) ...

Thank you :) Only the finest indian pale ale this time. I use diluted acetone for older stuff with rosin flux - that would otherwise leave a white residue behind after cleaning with IPA only

I think that unlocks some of the calibration and eeprom programming functions.

But it needs a password. If you haven't seen it on Discord yet, can you guess what it is?

Hint: It's not 1234 000 password root etc ...

I would definitely buy an electronic torque wrench (at around $200 depending on specs), even if the limit is manually set. Low torque values (like for self tapping screws in plastic) are of particular interest. I usually do 2 step process. Setting the number of times to hit the spec could be really interesting for metrology stuff.

You know it's serious business when a piece of equipment requires a key... Unless it's an old 286 or semi truck or something. Also, are you hoarding Volvos? Is the silver one an S60R by chance?

Ahh the countryside is so pretty, I'm constantly bummed that I'm stuck in the Arizona desert. I know it's not exactly the point of collection, but that YAG laser seems like it's more trouble than it's worth. Does it have any specific functions any of your other high-power pulse lasers can't do? Are you looking at modifying the nice big optical table?

marcoreps - 4 Apr 20 19:23
Wouldn't mind trading places! Our countryside is riddled with human activity, poisonous chemical agriculture, greedy evil animal agriculture right at the border between legal and illegal, even in the remaining forests you are never out of sight of a hidden hunters high stand. Whoops, sorry for the rant, maybe I'll vent my frustration in a little vid some day and subject everybody to it :) Yeah that YAG laser was originally used to pump that big orange box behind it. That's a dye laser. But I don't really need that one either, so yeah it'll probably all be boiled down to a general purpose optical bench. It already has mounting holes all over 🥰

Nice find on the Trumpf laser. They develop really, really cool stuff. I just finished my internship at some company which uses quite a lot of their lasers for spectral analysis. Would be nice if your device will work again!
user avatar
marcoreps - 4 Apr 20 19:10
Yeah I'm thrilled about that one! Fiber laser still has that concerning off-center issue which is why I am reluctant to do anything with it at the moment ...

i have one of those hand wheel things and there's a big lag between input and actual movement.. often it'll lag for like 2 seconds and then rapid fire all the inputs if there were multiple, giving me a heart attack in the process lol. i use a different controller though. is it good on linuxcnc?

I am taking a few measurements of an LTZ1000A voltage reference to turn them into statistics. Then I am taking apart the Solartron Schlumberger 7081 bench top voltmeter to find opportunities for improvement. I am CNC machining a new front panel segment to fit Pomona 3770 low thermal EMF binding posts. Finally I am installing an ultra-precision LTZ1000A voltage reference, but the new components have to settle down before we can see any results.

Just picked up a 7081 on ebay for $475 USD. It arrives in a week. Will need work because it doesn't turn on but keeping fingers cross all the parts are there. Seemed like a lot better risk than paying $4000 for a 3458A and finding out it needs a $1200+ board. I will go back through your Solartron videos and see if I can learn anything that will help me when it arrives. Thanks for the videos. Keep the volts flowing! Rick PS. I picked up a Keithley 181 from watching your vids. Love my Keithley

It'd be interesting to see what you do receive - the issue with "recycled" or "salvaged" parts is they're often not treated very well in the process - I'm not sure what state it would leave those references in.

I don't mean to be a naysayer but they make a 5.5 barrel to USB Type C PD adapter for a couple bucks that plugs directly into a TS100. I really don't see the value of replicating the TS100 as it already has open source software and schematic. Maybe I missed something. Please enlighten me if I did.

I'm way late to respond, but I believe your mystery cylinder/actuator can be seen in the first 5-15 seconds of this video https://youtu.be/xiqaWOMqS4I it's a conveyor for making manufacturing cells with multiple processes. So you add one of those as a bumper and stop at each step (where you'll have a robot or something performing work on the piece on the pallet) and then the cylinder will drop and allow the pallet to go on to the next station.

25 years ago, I went to a German trade show. It was the major agricultural expo at the Hannover Messe. As a US midwesterner, I was only used to state fairs. I could not fathom the enormity of agribusiness in Europe and how cool and professional it was. Of course my favorite of all was the boiled egg machine, pumping out thousands of perfectly boiled eggs for the visitors. My brother-in-law was working for the US National Pork Producers. This was before confinement feeding came to Missouri. I knew what was next for the thousands of pork producers in Missouri, Sure enough, in ten years they were all out of business as pork production shifted to confinement in Missouri. It was an apocalypse for many of the small farmers where I live. In any case, I loved your little visit south to this trade show. Trying to plan a European vacation again. Need to figure out what's on the schedule for a big trade show in February. Thanks for sharing this journey.

Do you have any plans to add an optical recognition system? It would be cool to have some magnetic tool holder you could place anywhere on the steel bed that could be recognized and used to swap tools without attendance.

damn that would be elegant! maybe even hand-holding the tool anywhere in the working volume and have the spindle come over and collect it 😅

"Maybe we can trim some metal film resistors in circruit soon..."

This is a loaner for now, so no teardown :( But it is a great source of inspiration and motivation.

EDIT: I've added a few more things and will probably make this a public vid right before the fiber laser!

Imagine having a choice of buying bulky unit and small one for the same price with similar stats - which one would you buy? Also by buying smaller devices you can save up on buying new tables(just look at Marco Reps table for example)

To flip out the top floor of the fiber laser I'll have to unwind some fiber from that slanted spool ... and it creeps me out. My instinct says that it's important, because they wouldn't do that for no reason. But on the other hand the fiber is just held on with double sided tape, so it can't be *that* critical, can it? Any fiber lazer experts around?

Uhh looks fancy, but 200$ might be a bit above the budget. Next equipment will probably be a new soldering station. What’s your current favourite? Pace or Unisolder?
user avatar
marcoreps - 25 Aug 19 16:11
Yeah, it's definitely a specialty thing and I haven't even found the niche it fills yet. I am still using minimalist Pace. Unisolder with a nice, large OLED display would be nicer, but only if taken all the way with JBC hand piece, stand, enclosure and maybe a pair of JBC tweezers as well? Interesting alternative: Chinese STM32 T12 station

Guys and gals, is this too boring for a public release? I was aiming for a little demonstration of a LinuxCNC + Mesa setup and its advantages but that made it neccessary to cover all the basics that probably everybody knows already.

I am adding some oscilloscope jitter histogram measurement and some VFD and servo load displays to the LinuxCNC UI today, maybe that'll make it a bit better?

I'm not sure how much my opinion counts in this case, since I'm a CS major so my own interests and hobbies are much closer to this than the 'normal' content. But as I see it this is exactly the type of thing people come to the channel for. The series in particular is about documenting the journey/process of creating a professional grade CNC from scratch. The software and tuning parts are an important step and can't or shouldn't be left out. It just so happens that this is also right up my wheelhouse (right up my alley?).

Reps and live streaming are still incompatible as you've seen, but I am not giving up: Teamviewer runs beautifully on Debian in spite of real time LinuxCNC mod. That and a permanent live stream would allow complete remote control and supervision ... for longer jobs without human presence? It'll take some time for me to trust the machine that much, but it would be so cool.

A number of years ago, my then-partner (who, incidentally, was heavily involved in coding Linux CNC) brought home a 5-gallon bucket of this nasty-ass petroleum-based coolant and dumped it in his CNC lathe. You could smell it all over the house, even though it was across the basement and through a steel door to the shop. I made him drain it out and get rid of it. He then found some soy-based coolant that won't stink up your house and eat your lungs. You might want to look into that stuff. You need to take care of your lungs and other important parts, bud! Machine is looking good, though. A bit disturbing to see you used a water filter ask a toxic coolant dump, though... <.<

Oh, a LinuxCNC expert? Very cool, I think my next public vid will be about LinuxCNC mostly! Thanks for the health concerns, do you have a name / link to the alternative product? I don't sense any smell at all yet, the shed just smells like an oil refinery! The water former water filter was shipped with the fog buster nozzle, very thicc plastic and it's only pressurized to 2 bar.

Should you not put some protection in place over the rails and ball screws before you blast tiny metal particles all over them? edit: Also, quite jealous here. you manage to have the nicest toys :)
user avatar
marcoreps - 3 Aug 19 07:32
Yes! But! rails and ball screws have wipers which I'd trust to keep metal chips out. PCB or other carbon / glass fibery / mineral dust not so much ... I am desperately looking for telescopic way covers or just bellows for starters. Maybe I'll just make a roll-down curtain from https://shop.hightechflon.com/PTFE-Teflon-Glasgewebe-folie/Page-16-1-101-1313.aspx for now?

Not much happening yet, but later today I hope.

I just hooked up a quick gopro -> rtmp -> wifi -> long ass eth link into another building -> nginx on windows -> youtube connection and we'll see how long that lasts ...

Which motion control card are you using?
user avatar
marcoreps - 6 Aug 19 06:53
Mesa 6I24 ~ tons of IOs and a lot of FPGA on that one, but otherwise pretty bare. I am using most of the pins directly from the card, but for some special functions I had to make my own add on board. If I had to make that decision again I would probably try one of their ethernet cards like 7i76E with a bit more stuff built-in ... isolated or differential IOs, analog inputs, etc

I know it really can't compare, but last night I did my first hello world for the MPCNC I have been building. No magic smoke and only had to reverse X axis direction. I have been waiting for the debut of your beast. I hope I am free when you stream. Should be soon. It's getting late for you, although night is the best time for projects.

We have a formlabs machine at work that will do very fine threads and tiny medical stuff just fine actually, the biggest inaccuracies using the machine come from improper washing of parts. They're great machines, and I actually prefer it to our Stratasys SLS machine
user avatar
marcoreps - 16 Jul 19 22:21
Ah, really? Interesting. Moai is struggling hard with that - after a ton of fine tuning. Do you have a link to some instructions for proper washing? I bet I am doing it wrong :)
user avatar
User #22158262 - 17 Jul 19 01:29
Sadly, we use Formlabs proprietary Wash and Cure stations and their given settings, so I can't give you much besides their reccomendations. maybe after all of these CNC shennanigans you could try one-upping their stuff ;)

Is it at all worth to expose pcb:s with this setup or would the resolution of the LCD be to limiting?
user avatar
marcoreps - 17 Jul 19 18:06
The pixels seem to be 47µm x 47µm which is a lot better than what you'd need for PCBs! Personally I have completely stopped etching my own PCBs tho, because of the unbeatable Chinese prices, even for prototypes ... but now that you mention it, that would be a very cool thing to try on that printer!

So Marco, will you try it out (please)? I‘m interested as well if this does work out! I probably can‘t stop myself forever from buying an (M)SLA printer (I hope to make it till next month). And to know of another application for it, would be a nice relief for the doubts about opening one more money sink in the 3d printing area...

well, the smell is not quite as bad as some people say, but the combination of noise and IPA cleaning really makes a separate room desirable ... I for one have sacrificed my kitchen :) If you ever need anything printed, send an stl file. All machines are standing still at the moment

Aw, man, first it was that Cetus 3D printer that you showed that had me sorting bottlecaps from euros so I can scrape together enough to buy it, and now this? Come on... But seriously now, how much of a headache is it with these printers? I mean in terms of getting the resin then cleaning up after a print ?
user avatar
marcoreps - 17 Jul 19 16:40
weeell ... the IPA stench during cleaning is worse than the resin. A separate room would be beneficial. If you get too often or too much resin on your fingers, especially when dissolved in IPA you can get serious health issues. Support is sometimes hard to get right and if it fails you can end up with a lot of fine debris in your resin - which sometimes is so bad that it justifies dumping the entire vat. Even successful supports will leave tiny spots on the print after breaking off. But as I said in the video, if you need to print these small and precise parts, there has never been a better way to start. And when you get it all right, it's very fulfilling.

User #2760445 - 17 Jul 19 17:35

Quick idea for your human water cooling solution: Combine the pants with the GARDENA Micro-Drip-System to get evaporative cooling. Put the drip hose across your shoulders so the water can flow through your clothes and partly evaporate there. The excess will then collect at the feet where a pump can suck it circulation.

Awesome video, really gets my brain juices flowing. I've been meaning to do my own thermal EMF measurements for some of my gear. Also, care to share the P/N for the Pomona spade lugs you got ? I could look around Mouser, of course... if I wasn't so lazy :D
user avatar
marcoreps - 6 Jun 19 22:35
Thank you! Pomona 3770-0 are the black binding posts which I'll probably use with copper lugs from a hifii shop Pomona 2305 are 2 spade lugs to plug 4mm banana plugs into. With enough force everything is, but these are really not good candidates for crimping to cables directly. Somehow I didn't get that impression when purchasing. Pomona 5295 seems to be a neat pre-made low thermal EMF cable

CNC Spindles tend to run for extended periods of time VS hand held power tools its rare for a hand held router to see an hour of continuous work, So the easiest and most reliable way to get that duty cycle with a bigass motor is to actively cool it.

Interesting teardown. Was the spindle over heating caused by you or someone else?
user avatar
marcoreps - 27 May 19 12:06
Guilty. I ran it without coolant for a few seconds yesterday, not expecting it to get that hot that quickly
user avatar
User #4684889 - 27 May 19 12:24
A few seconds? I really doubt that caused it. The amount of thermal mass there would take much longer to heat up to a point that causes damage. People often run these spindles without coolant in low load applications. It's the bearing that heat up, not the windings.
user avatar
marcoreps - 27 May 19 13:22

Some feedback on the video: The speaker advertisement was too long. I almost turned it off because of it and I would've missed the cool project at the end. Maybe make it clear at the beginning that there's actually a project inside the video? Also the horn background music when you got to the CNC part was too distracting to hear your voice.

Thank you, I think so too tbh

I didn't feel like that. Marcos advertisements dont really feel like advertisements to me so i'm having fun watching them. Way better to have him tear the thing apart than other youtubers.

From juuuust the right angle, that Benq stand looks like some kind of phaser from Star Trek (the original series)....or Galaxy Quest?

Is it just me or does that lanky Z-Axis look a bit silly?

Full video tomorrow or the day after~

Excited to see it going! What's the humongous z-axis plate for? Just to hold the giant spindle?
user avatar
marcoreps - 14 May 19 07:27
It extends past the bearing block and shaft coupling to the motor mount. That's a bit wasteful, the stiffness of the thick steel plate is only needed between clamping plate and axis carriage. The spindle hopefully make it look a little more balanced, but it's not really that giant

Same company also make oil-free piston compressors, which are much less of a pain in the butt I suspect

I hope you're happy now....I feel obbliged to go out and get myself a new Jun-Air toy... errr, I meant compressor

Didn't get new intake air filters yet, so happiness is still incomplete, but soon!!
user avatar
User #358139 - 6 May 19 08:15
OK, the one I saw has not gotten dearer. It's the Behr Hella Type 8fx oil for AC compressors. Bottle still is about 25-50 EUR incl. tax. :) So you are not so bad off with the expensive original "not even a bit yellow" Jun-Air oil.

User #358139 - 6 May 19 08:00
Bloddy hell, last year it was just under 25 EUR +tax (~30 EUR) a bottle, just short of 500 ml. It's getting dearer by the day.

It seems like a bit of an overkill now, but when limit switches, spindle controls, tool changer stuff, coolant, servo status pins, hand wheel, 4th axis, etc. are taken into account ... maybe I'll use 1 of those 3 headers :)

The oil of that compressor is really dark. The color of it should look like honey.
user avatar
marcoreps - 2 May 19 07:36
Yeah, let me just try and convince myself that that is just dirt from the air and not abrasion from important metal bits :)
user avatar
User #358139 - 6 May 19 07:55
I recently learned that these are in fact partially oxydized abrasion particles in the ~1µm range. It is ok to a certain point. In cars however, especially Audi A3 TFSI these are partially responsibe for the camshaft drive chain lenghtening problems due to the 30.000km oil change interval. These particles slowly polish everything they are rubbed on. Better change the oil in regular intervals even if the bottle costs 30 EUR.

outside luckily! cathode to filament - if that happens and the PSU isn't grounded correctly, it would jump to me through a potentiometer knob, that's what that silicone tube was for

Weird! Fixed I hope. My source file doesn't have that problem and it's 4k60fps ... must have been a YouTube render glitch, because that vid only was available in 1080p. (Original https://www.youtube.com/watch?v=-XuvnUdRG80 )

You should get one of those "fosfor" plates that glows after being exposed to xray. Had 1 when was working at dental Xray machines.

eBay or the local equivalent of craigslist. In Germany specifically there's also https://yellowmed.com where you can sometimes find free ones, if you dismantle an entire system
