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

I'm still trying to build a cool night light. Here is an UFO for children or adults 😉 All done in 4mm plywood an 3mm acrylic. I used white LED's for the test, but I think green ones would be better. Drawing done in Inkscape.   All glued together. The small bar has to be … Continue reading Ufo night light. Design test

My new business card holder display. Of course with a microcontroller and LED's. https://youtu.be/TE0exnYknig I used 2 Ws2812 Led breakout boards and a Digispark microcontroller. Showcase

The piezo buttons worked perfectly for 4 years at ScottTv, but I think, I will try capacitive touch sensor buttons. Unlike the piezo buttons, they will not react if Scott is beating on the TV, but they will just work on the touch. Now I have to check if they are not too sensitive. Test … Continue reading New Buttons for ScottTV

First parts for this little Led light. It's for a children's room, so it will be batteries driven and the power on/off will be a capacitive touch switch. No moving parts and the small parts are behind a 3 mm acrylic window The basic Idea And here the first parts, to see if everything fits.   … Continue reading Dino Night Light For A 3 Year Old Boy
