There’s no SAO connector because I wasn’t thinking too straight at 4am designing these badges, but I’ll make sure to add one in future badges, because I agree that they’re really cool!

I’m working on 2 hardware projects right now! Fold-up, scissor lift, cross-cantilever 3D printer for open sauce M.2 FPGA hardware accelerator devboard All just for fun and open source https:/&#x…

I personally love this macropad tutorial and it's how I got into doing circuit board design in highschool: https://hackpad.hackclub.com/ . Before doing this, it's really help…

This is insanely cool, the noise they make is also really satisfying! What was the cost/time breakdown of the entire project because the flipdisc prices are hidden behind quotes and it seems like…

Thanks so much!

This is so cool! I'd love to see a write-up on how made it, and what you referenced because designing neural networks always feel like a maze ;)

We ordered the PCB's and badges separately, but it's extremely easy to assemble, you just attach the eink on using the FPC connector and the badges are already in a complete setup of the har…

Yeah the RP2040 is a bit overkill, but it's really cheap to get from JLC, easy to prototype FAST and easy if anyone wants to reference the design and create/program their own badges. I have …

I used https://eds.st.com/antenna/#/ to get an antenna that fit with a target inductance of 4.7uH and then used https://github.com/nideri/nfc_antenna_ge…

So the eink holds its state once it’s programmed so you do need an initial program of the badge through USB-C, and then the NFC uses passive RF harvesting.

The total ended up being about $10/badge for 60 (5 for badge, 5 for eink), and we made the mistake of not ordering enough, so we ordered a couple more that were about $1 more expensive each. We b…

Oh wow, I've never actually heard about the Lemontron, I'll definitely take a look at it for inspiration!

I also did forget to mention, but this project is OSHWA certified too :D https://certification.oshwa.org/ca000068.html …

Routing is honestly one of my favorite parts of making a PCB, there's something about the feeling of understanding exactly what each trace is doing that I find exhilarating. The problem with most…

I'm probably going to run Marlin just because it would be the first 3D printer I've actually made and I've heard it's more beginner friendly. I think Klipper also needs a dedicated…

4 layer boards actually make it easier instead of more advanced in my opinion. You can have a dedicated ground and power plane which makes routing much simpler, and the fields are much easier to predi…

That's a really cool idea! I have a couple idea's on how I wanted to do it: - Belt printer fitted into a briefcase (the harbor freight case form factor would be good for that!) - Positron st…

Hey guys, thanks for all the love :D The website went down because of the traffic and large images, so I've temporarily switched hosting, and it should stay up now (DNS propagation might take a b…
