Since I've been on a bit of a clock trip lately, and these little things are really tiny, I decided to create a test board for these two chips, the Epson RX8900 and the RX8130.Now I have the opportunity to get to know these ICs better 🙂 The Datasheets rx8900ce_1Download rx8130ceDownload The PCB I had … Continue reading RTC Rx8900 And Rx8130 Testboard
Binary Watch Ver2.0
https://youtu.be/tjXaxtLVo3o Intro This is my second version of the binary clock. It is square and also uses charlieplexing.This clock uses again the RX8900 from Epson with a +-ppm5 (+- 2,5min error per year).I am also working on version 3.0 :). The Soft and other Files can be found here (https://github.com/awall9999/Binary-Watch-Ver2.0) The Design As you all … Continue reading Binary Watch Ver2.0
5-12V Capacitive Touch Switch
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
New D.I.Y. Lampeshade
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
Pepper’s Ghost Illusion
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
Makerfaire Luxemburg 2022
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
LED-KALEIDOSCOPE
https://www.youtube.com/watch?v=shCdfYfanFI As the uncle of a 5 year old curious boy, I have to make something "out of the mainstream" for his birthday, as usual. This time just something simple like a kaleidoscope. Hmmm, I can do better than that, so I fitted it with LEDs and a battery, and it was an LED kaleidoscope. … Continue reading LED-KALEIDOSCOPE
Binary Watch With 18 LED’s
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
Herb Care 2.0 (update 13/02/22)
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)
Charlieplexing Tutorial
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
