Two wooden rings

I made two rings from oak wood. I had already made the boxes for the ring.

Two box designs for laser cutting

The material is 4mm plywood.

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”

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.

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”

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”

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”

One poster/banner I did last week.

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”

How i made my digital radio

This is my simple one-button radio. One button to turn it on and change the volume. There are actually two buttons more: first to select a new channel and second one to save it to memory. It was a project that taught me how to draw PCBs, what are Gerber files and so on. IContinue reading “How i made my digital radio”

Board game table

Last week I designed this board game table. It has four sides and users can select what they like to play. Most interesting part for me was to come up with a locking mechanism and 3d-print it. 3d and CNC files are designed completely with Onshape free maker version. Links Valmis mängukuup, mis ühendab põlvkondi.Continue reading “Board game table”
