When my Swiss cousin-in-law sent us her wedding invitation, I didn’t immediately think I’d get to see Hackaday.io user [antti.lukats‘] tiny FPGA projects as part of the deal. I’m really glad that I came to Switzerland for the wedding, and also got to be a part of an awesome meetup in Zurich’s Fablab. [Antti], who was at the meetup, is pictured above holding a small tube full of FPGAs, he’s a Hackaday Prize Best Product finalist with FPGA project DIPSY.
As is becoming the norm for Hackaday meetups, we ask people to bring projects. We then count all the people who want to present something and squeeze all the presentations into just about 90 minutes. Before and after the lightening talks, there’s always plenty of time to walk around and see individual projects, meet people and of course eat and drink.
There were 3 walking robots and 2 rolling robots presented. [Arian’s] Roomba had the popular ESP8266 hacked into it. [Simon] brought a RaspberryPi powered rolling robot. [Thomas] brought a walking robot which walked quite well. The last walking robot of the night was shown just on video. [Radomir Dopieralski] brought his Hackaday Prize entry, the very cool and easy to use Tote robot. The Tote aims to fix the problem the world has without enough walking robots by creating an easy platform to build walking robots upon. It seemed at this meetup, that [Radomir’s] dream of many walking robots had been found.
[Oscarv] brought the insanely cool PiDP. The PiDP-8/I is another Hackaday Prize Best Product finalist, it’s a replica of the first minicomputer. [Oscar’s] version uses a Raspberry Pi to recreate all the operations. [Neil’s] SoftVGA is a software only VGA generator. I expect to see many more cool projects like these two next week at the Vintage Computing Festival in Berlin. I’ll be there with [Elliot] and [Bilke] and we’re having a Meetup with the VCF folks Oct 3rd.
[tamberg] presented a beautifully fabricated clear cube with switches on the inside, a metal ball rolls around and activates the switches. The Larson scanner next to it was designed by [stefan-xp]. [Yvonne] discussed her recent light painting “Topology of Light” and [Isaac] was sick of playing 4 in a row alone, so he built a robot to play the game with!
A popular hacker project is automatic watering of indoor or outdoor gardens. [Effi] nailed it with a brilliant presentation about moisture sensors while showing us how well her plants are doing.
There were far too many projects to list everything here, but [Thibault‘s] Bit Shift project really caught my eye. This project has several panels daisy chained together with layers of blue thermochromatic pigment on top of white primer.Each panel is a PCB, a heat pad controlled in a timed heating sequence powered by ATtinys. After each panel heats up, there is a 20 second delay before the next panel heats up. When the blue thermochromatic pigment reaches 37°c it turns transparent, and the white undercoating shows through. As the square cools down, the transparent pigment turns blue again. You can catch the video here.
