welcome to my ~ homepage

Hi yall,

I'm mainly interested in DIY electronics. This small etching box took my tinkering to the next level. Double sided PCBs are a step up from veroboard madness.

Current Projects

LCR Tweezers

Recently I saw a professional LCR meter built like a tweezer. This piece of equipment is rather pricey and no where near my current financial situation. BUT! there is a DIY component tester built around the good ol' ATmega328P (and similiar). If you don't know this you should check it out: Original AVR Component Tester
You can get these for real cheap from the web (like 10 bucks) and they work fine. However until now no one has made the effort to package this into a tweezer, so here we go!
As of now the first prototype is ready. It's build from junk I had laying around and it works. The next steps are designing an enclosure and figuring out a way to make it work like a tweezer.

All electronics are working fine. Today I got around to ordering the first 30 PCBs. The only thing missing is a CAD model for the enclosure that incorporates the tweezer legs. CAD modeling is pure pain >:(

Sci Fi Goggles

Well the headline sounds like much more than it actually is. Basically its just an LED stripe fit into goggles. The LEDs are controlled with an ATMega328P AVR microcontroller. For more funkyness there is also audio reactivity via a small microphone.
Because this thing is so simple the end result looks actually really good. Adding new LED patterns is also really easy. For programming I used the Arduino framework. This makes programming much more convenient.

Time for some workshops with this thing :)
The first batch of PCBs as well as the parts finally arrived. Let's see what people will build with this thing.
If you want to take a look at the mess of code or the KiCad design files you can find them here:
