Üks LED valgusti 15 LEDiga. LEDe juhitakse läbi WS2811 kiipide, mis lubab kõikide LEDide heledust kontrollida individuaalselt. Tahaküljele saab kinnitada ka Seeedstudi XIAO arendusplaadi. Või siis kontrollida eraldi oleva mikrokontrolleriga. Mina kasutan siin ESP32te. Neid valgusteid saab ka järjestiku mitu tükki üksteise järgi. PCBd valmistas ja printis PCBWay. Komponendid jootsin ise. PCB läbimõõt 10cm.

The Breathing Light PCB board
The biggest PCB I’ve ever designed has arrived. And all RGB LEDs work as planned. Manufactured by JLCPCB. The diameter is about 260mm. It is still necessary to make the body and finish the firmware.
Photocoupler PC817 circuit
My photocoupler (optocoupler) board design. I added four resistor places to combine them with different input and output voltages. Also added a diode for reverse voltage protection. Does the output side need it? Any other suggestions? Updated version Update version with a two-way communication.
First development board prototype
PCBs arrived for my RISC-V CH32V003F4P6 development board.As always PCBway services are very fast. It was the last part I ordered and the first, that arrived. Soldered one of the boards together. So far it works and I’m surprised that I soldered the LEDs in the correct orientation on the first try. I also likeContinue reading “First development board prototype”
Inside the Y22 Smart Watch
I recently took it apart this Y22 Smart Watch and will document all images here just in case. The screen glass was already broken.
Stop-motion animations with PCB
Here are my two short stop-motion animations with PCB. Recently I have used a lot of The Dave Brubeck Quartet music. Especially the Take Five. I think the live video from 1964 is especially cool. And I used some AI programs to upscale it. It took around 10 hours and turned my computer really hot.Continue reading “Stop-motion animations with PCB”
A nine-cornered PCB
This is my new nine-cornered MCB. I plan to add nine gas sensors onto this board. It would be my artificial nose experiment. The flowers are hand drawn and vectorized. It is made by PCBWay. It’s the first time when I ordered matte black coloured boards. And I really like that it makes it feelContinue reading “A nine-cornered PCB”
The Watchman
The Watchman is an Electronic Sculpture. The Watchman is an electronic wall sculpture that combines art, night lighting and security. The working principle is very simple. It all is built around of Seeed Xiao RP2040 microcontroller board. Powered by a 3.7v Lithium-ion battery. RCWL-0516 doppler radar sensor detects the motion and sends the signal toContinue reading “The Watchman”
Golden Fase
My face-shape PCBs have arrived – kindly made by Seeed Studio Fusion service. On the backside, there are one XIAO RP2040 microcontroller and two synchronous buck converters to make 5 and 3.3 voltages. I found these Synchronous Buck Converter schematics, made by @wagiminator I incorporated them into my board design and it works pretty well.Continue reading “Golden Fase”
Face-shaped circuit board
This is my idea to make face shaped circuit board. It will use the Seeed Grove Vision AI Module. The plan is to make an electronic sculpture that uses machine vision. And the MCU board is a tiny but powerful Seeed XIAO RP2040 that uses the same microcontroller as Raspberry Pi Pico.
The Pink PCB Update
Soldered the components to my pink PCB. It looks good. but not everything works as I planned. The first post.
Pink PCB, why not
New and pink with gold! One of my experiments to combine electronics and illustrations. And actually, it will be a sculpture.Assembly will be difficult because some holes and components are purely decorative. But others must be precise. Final PCB made by PCBWay: Different PCB colours at different angles! Design ideas and sketches. Although there isContinue reading “Pink PCB, why not”
Golden Lion
I really like these golden lions. They have good contrast and blue with golden is a classic combination. There has a lot of coats of arms with this combination. The board is just a Raspberry Pi Pico carrier board. I only needed to change the Pico footprint to remove all through-hole pins and pads fromContinue reading “Golden Lion”
One PCB designs
Here are one PCB designs I have made recently. In spring I bought TinyML Cookbook and there are a lot of detailed examples of how to use machine learning on microcontrollers. So I designed this board to experiment with it. On this PCB, with is made by PCBWay, is room for Arduino Nano 33 BleContinue reading “One PCB designs”
