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”

I found this EEPROM
I found this tiny EEPROM from an old random board. Soldered it on copper board to use it as a through-hole component and to use on the breadboard The EEPROM is 24C02N. It uses i2C to communicate and is relatively easy to read/write. I used Arduino Nano for that. Some functions I wrote: EEPROM memoryContinue reading “I found this EEPROM”
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.
Artwork that knows when you are taking a picture of it
This is my electronic artwork inspired by Peter Vogel’s and Walter Giers works. And I am pretty happy with how it came out. It looks cool and it has artificial intelligence (to a limited extent). It recognizes when you are taking a picture of it with a mobile phone. And it uses only a microcontrollerContinue reading “Artwork that knows when you are taking a picture of it”
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”
Lillering
This coat of arms is a circle of flowers (Lillering). Green PCBs and oak wood are a nice combination. There is five shift-register to control LEDs.The Arduino’s original shiftOut() function is quite slow. I had to simplify it to make it work with my configuration without noticeable flickering. Board Arduino Pro mini 16Hz Atmega328 5v.Continue reading “Lillering”
Where the robots are rushing?
I made a short and simple stop-motion animation.
Coat of arms of the accountant
I like history and I like medieval European coats of arms. Of course, nowadays, their design has its own rules and order. But when I have searched the early ones and found some. They can look wild. So I thought to make some mixed ones — medieval combined with modern electronics. The hardware part isContinue reading “Coat of arms of the accountant”
Cistercian keyboard
Keypad with cipher numerals. This keyboard is for me more of an art project. And the opportunity to learn how things work. What is the underlying code and history! Arouse people’s curiosity. What are Cistercian numerals The medieval number system was invented by the Cistercian order in Europe in the 13th century. Cistercians are aContinue reading “Cistercian keyboard”
tARTu Sculpture Auction
Two of my works will be in the tARTu first sculpture auction on 17. May 2022. Puu Link to the auction catalogue: noorkunst.ee/oksjoni-kataloog/item/1018-27-tauno-erik-puu More information about the sculpture is on my page: Puu.

Paper Sizes
This is more than ten years old talk from one of my favourite YouTube channels Gresham College by professor John D. Barrow (1952-2020). It talks about the different paper sizes we have and what are their mathematical properties. Here are some screenshots with interesting information. International standard paper sizes. A series Georg Christoph Lichtenberg proposedContinue reading “Paper Sizes”
