I write this down, for myself, and to help others not to search for hours too. I bought a few new, ATtiny 85 and Atiny13 at Aliexpress. It was the first time, I used these brand new controllers. So what can go wrong? EVERYTHING 🙂 First, I soldered them to the PCB-breakouts Sot8 to DIP8, … Continue reading Brand New Attiny’s And The Problems

This undress alert is for my thirteen-year-old son suffering from autism Scott still has problems with the toilet, and because of his limited communication, he takes off his clothes when he is in his room. This does not end, every time, very well. We always keep an eye on him, but I thought it would … Continue reading UD-Alert V1.0

I finally found the time to solder all together an to write a small test program for the Digistump micro controller. It's just changing the brightness and a few color combinations, but it works. Now I have to optimize the software for my bases, so I can switch it on and off, change the color … Continue reading RGB module for my LED bases

I corrected a few issues in the design, but created a few new ones :(. Never mind, I took the chance to try a few paint technics with glue, toilet paper and acrylic paint. Not perfect and a little bit too much, but the next one will be better :).  

This Weekend I laser cut the first parts of the Word-clock. Mounting all together. First test run of the multiplexer  

It was not the plan to do it like this, but it was nearly impossible to solder these LED's by hand. So I used a plastic sheet and my laser to create a stencil. A few years ago I bought a 20$ oven that should be transformed in a reflow oven, but like other projects, … Continue reading SMD Reflow Soldering (had no choice)

I always had the idea to build a "WORD CLOCK" for myself. Most designs are flat and somehow always the same. I wanted to design mine, slightly different. This is just the basic idea, but I think I'm on the right path. 3D designs done in Sketchup 8.

Today I tried to build a light badge. I use 3mm mdf wood, a CR2032 and a rgb LED slow color changer. It turned out not to bad 🙂 https://youtu.be/B0AApjrFAFk Like always, the 3D design in Sketchup 8.0, to check if it could fit together To the laser The middle part is glued to the … Continue reading RGB Light Badge

I rarely work with SMD LEDs, but I quickly realized that's not easy, to find the polarity, and without putting them under power, you will never know the light color. So I quickly built me this tester. It's just a CR2032 battery between two parts of wood or plastic. To conduct the electricity I took … Continue reading Test Tweezers For SMD-LEDs

With this weird idea, I'll try to build a Mask where the LED's inside are controlled my the pulse and the music. There will be an integrated MP3 player with relaxing music or deep tones to concentrate. The light pattern will help to meditate. First parts are ready   Connect the RGB LED's to the … Continue reading Some Brain Hacking Stuff
