Hello, I built another LED lamp and wanted to use a TTP223 capacitive switch as usual. But Led Stripes have 12V and there was my problem again, the available TTP223 boards are 3-5V and have only a small switching current. Besides, I don't need the LED on the board.So I built a prototype with what … Continue reading 5-12V Capacitive Touch Switch

Found this little floor lamp in the trash. After a 10min crash design on the computer and with the help of my laser cutter, it turned out better than I thought. The lampshade is made of 4mm plywood. I sprayed the whole thing black and glued it together. Then I applied a metallic look with … Continue reading New D.I.Y. Lampeshade

Hello,Due to the great demand how I created the dance show at Makerfaire, I am writing this documentation.First of all, the principle was used by John Henry Pepper in 1862 on a stage to make a ghost appear.There are many instructions on the internet on how to use Pepper's ghost effect. Often people talk about … Continue reading Pepper’s Ghost Illusion

Great weekend at the Makerfaire Luxembourg. I met great people. My projects were very well received. The children were thrilled by the arcade game and the eye-catcher, the Holobox, fascinated the adults and the children. https://youtu.be/lCOWykMPdzc The Holobox https://youtu.be/HQPdKviymPI Arduino Led Arcade https://youtube.com/shorts/BWbMm0uD6MQ?feature=share

For years I have had the idea of a homemade wristwatch. I've been racking my brains for quite a while on how to go about it. These points would be the biggest challenge: The power consumption, the number of components, precise in time and the size of the watch. So I tested several things individually, … Continue reading Binary Watch With 18 LED’s

Working on the next attempt to grow herbs on my windowsill without having to worry much about it. This time I only have light, which is controlled via an Arduino time.The Leds are 3Watt lights. Three full spectrum and 2 red. That will probably be enough for 3-4 plants.The plants are watered via the capillary … Continue reading Herb Care 2.0 (update 13/02/22)

How to control 30 LEDs with only 6 wires on the Arduino. The trick is charlieplexing. It works because the I/O pins of the Arduino are tri-states. So they can be high, low or high impedance. Maybe someone can use it. This is a good solution to control a lot of LED's with only a … Continue reading Charlieplexing Tutorial

Here is the new updated version of Scott's PECS board. The Picture Exchange Communication System, or PECS, allows people with little or no communication abilities to communicate using pictures. People using PECS are taught to approach another person and give them a picture of a desired item in exchange for that item. By doing so, … Continue reading PECS Communication Board V2
