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….

Soldering Boldport Club project “The Matrix”

Posted on 2017-03-18 by Lucky Resistor

For the Boldport Club project “The Matrix” I used hot air soldering for the first time. After some experimenting and with help from Boldport Club members, it worked really well. I could colder the 120 LEDs in less than 10 minutes to the board. I made a video about the process. Please keep in mind, I…

Today I tested a number of SMD LEDs for the plant watering sensor project. I soldered all 13 LEDs I shortlisted onto a small board and connected it to an Arduino Zero Pro. So I could try the different flashing styles I planed to use more or less automatically. That way I could focus on the LED flashing itself,…

Outmoded Sequencer Music Demo

Posted on 2016-08-19 by Lucky Resistor

For the demo video in my previous post, I did not really choose nice melodies. So I created a small composition using the outmoded sequencer: For this music I connected the outmoded sequencer directly, after the potentiometer for the volume control, to an audio interface. Now I recorded the sound of the sequencer while I…

Boldport “The Cuttle” Arrived

Posted on 2016-08-17 by Lucky Resistor

Today the new project from Boldport Club arrived. It is called “The Cuttle” and it is a minimal configuration of the ATMega328-PU microcontroller with minimal elements to get it running. As usual the PCB is artfully designed in shape of a cuttlefish. Soldering was easy this time. Here some photos of the project how it arrived and…

SMD Soldering

Posted on 2016-08-112016-08-11 by Lucky Resistor

Here a video where I solder a SMD practice board. While the 1206 and 0805 are more or less easy to solder, the really small 0603 cause a lot of troubles.
