Electronics Invisibly Embedded in 3D Prints

Posted on 2021-01-04 by Lucky Resistor

After successfully embedding magnets, I started experimenting embedding whole PCB boards into prints. I am sure, this is no new idea, but I found it very interesting. From the outside, the printed object looks solid and there is no trace of the board visible. The board and all electronics are perfectly sealed in the part….

“Read SGP30” Command-Line Tool

Posted on 2020-12-19 by Lucky Resistor

I published another small command-line tool for Raspberry-Pi. This time one to read data from the Sensirion SGP30 sensor. While you can communicate over I2C with sensors using Python, I found it not as reliable as using compiled C or C++ programs. To combine the two worlds, I started writing really small command-line tools, which…

“Read SHT31” Command-Line Tool

Posted on 2020-12-132020-12-13 by Lucky Resistor

For various sensors, attached to Raspberry-Pi computers, I wrote small command-line tools to read the sensor values over the I2C connection. While you can do this with a Python script directly, I found using a compiled C or C++ program accessing the low-level device more reliable. The program I publish today, reads temperature and humidity…

Storage Box for 45º Belt Printer?

Posted on 2020-12-072020-12-07 by Lucky Resistor

I created a version of my storage box for 45º belt printing. It would be ideal for mass production. Because I do not own a belt printer, this design is a wild guess. If you own one, I invite you to test this design. The box has to be printed sideways, the shorter side in…
