Planting table

My drawings on this planting table. First I drew on paper. Then I drew over the vector format. Printed on wood. The planter table/chest allows several generations to grow plants together. The table is designed in such a way that even a person in a wheelchair can move around it. In addition, children can helpContinue reading “Planting table”

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”

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”

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”

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”

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”

Kõnnõtoro ehk ruupor

Lähteülesanne Tuntud inimene, kes võru keeles kõnet peab (või teeb mõne muu teo, mis toetab võru keelt), kannaks tema ametit toetavat atribuuti. See peaks sobima kanda nii mehele kui ka naisele. Praegu on sõelale jäänud kolm eset: (jalutus)kepp, kaelaraha ja ruupor (ehk kõnnõtoro). Oleme mõelnud, et ruupor võiks meenutada Pähni kõlakodasid.  Soovime Tsentrilt tellida puidust/vineeristContinue reading “Kõnnõtoro ehk ruupor”

Custom Wooden Mechanical Keyboard

I had one old and cheap rubber dome keyboard with missing keys. So I take it apart and found this controller PCB board. The board pads were coated with graphite. I removed it and soldered wires on it. And put it on a breadboard. Then I mapped all rows and column combinations to find whatContinue reading “Custom Wooden Mechanical Keyboard”
