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

Finally ... uh almost done 🙈
PWM DAC needs some more love and a conclusion at the end is missing.
Anything else you'd wish more details about? Editing the final version now
Not sure what happened here 🤭 this project started as 'ts80p.prproj' but the soldering iron didn't offer a whole lot of talking material. So instead I started rambling about noise ... for 25 minutes ...
The previous posts are patreon exclusive and because they have fewer than 469 views I would like to encourage you to watch em 😇
@ 6min 30sec U: Unlock
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 ...

Look what I found about that charge sensitive amplifier:

Happy involuntary holidays, hope you are all well!
If anybody wants to come and pick up some YAG laser parts or that entire cabinet, let me know! I only want to keep the long black thingy.

I had to shuffle some trivial details in this post a bit to keep the sources safe. They are not messing around in the high frequency light business 🕵️

I am documenting and reconstructing a few things here: https://github.com/marcoreps/5700A
I have a spare board, a TS100 husk and a bunch (not all) of parts. If anybody wants them, leave a comment and I'll send everything to the comment with the most hearts!

^ and nothing else! Next step will be a careful power on, some cleaning and maintenance, ...
New and improved version!
Wow this one took forever! I kinda made the CNC Spindle video at the same time, so that will also be finished soon. And then I have quite a large backlog of small stories about TIG welders, particle detectors and Japanese high voltage test gear 😵
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!

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?
EDIT: Thank you for the feedback! I've smoothed over a few rough edges anyway :)
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?
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.
Live action later: https://www.youtube.com/watch?v=MS_rq-nBlxA
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 ...
Latest LinuxCNC, FPGA motion control card, PID+Step/Direction and spindle adventures will be edited in a bit
New junction box and lighting are almost done. First chips ETA: a tentative thursday
it's a good one ... the printer, not the video I mean
- New shed
- Reinforcing with polymer concrete
- Spindle details
Best join the Discord server by creating a Discord account and linking it in the Patreon account settings for a cool rank, or just here https://discord.gg/758NGRF
It's a modern chat server thingy and imo much more convenient than the Patreon website.

Not quite there yet officially, but relatively speaking we are at 100k subscribers and that calls for a special. Double low voltage vintage Keihtley action. What do you think, is that too much to digest in one go?

prolly not, but it was fun to try
Is it just me or does that lanky Z-Axis look a bit silly?
Full video tomorrow or the day after~

It looks like 100k subscriber day might be relatively close to first CNC chips day 🤔 How are we celebrating?
@4:24 if you like your OCD, don't look too closely ... I've already removed it 😇
I am not secretly turning into a mechanic, I promise! But the machine stuff needs to be out of the way for these guys are ready to come out:
You may have seen the unboxing part already, but the rest is new
With a daily routine of drilling and tapping in the past weeks, there wasn't a whole lot of Patreon material - but I am almost done now :3
Starting to drop a few subtle hints about, but not revealing the full extent of the CNC machine just yet 😇
