I had this cheap USB stick that I had to take apart in order to rework the connector soldering. Once the soldering works achieved, I had to think about a quick and dirty enclosure which resulted in this: Two – almost – symmetrical parts. The top one has a bump and a small hole aligned […]
I have multiple projects in mind starting from a metal detector up to a NMR in field earth spectrometer which require one or more coils in various shapes and sizes. Here is the presentation of a double coil, 100 mm diameter, 5 mm thickness. Here is a zoom on the back side of the coil […]
Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 3D printing is awesome. I am even wondering how I could live without it. I mean, in my professional, domestic and makers life. Before 3D print, I would have used wood, metallic wires, sheets of PVC or even cardboard to build parts in the quick and dirty mode. Just before 3D printing, I was also […]
Part 1, 2, 3 DC-motors are every where in many form factors, many performances and configurations. The aim of this series of posts is not to cover all aspects of DC-motors as there are so many publications available, most of them being of excellent quality. Firstly, I will concentrate on the most common brushed DC-motors . Next […]
Time for tidying up my bench ! As electronic components are getting smaller and smaller, the need for suitable storage boxes emerges. Here is the description of an original storage cupboard that I designed for SMDs as well as for very small mechanical parts such as watches spare parts. Here is the picture captured from FreeCad that I […]
Part 1, 2 Most of the electronic diagram shown here should look familiar to the readers of arduinoos posts. The ultrasonic sensor is added to what was described as the test bench for stepper motors. Here is the list of the required components: An Arduino UNO baord (Should I introduce it to you ?) A […]
As a big fan of 3D printing, I had a lot of fun watching this video In the next future, this is what we will hear from NASA records: “Hello Houston, we have a problem” “How can we help ?” “Could you email us a cable clip so that we can tidy up this harness” […]
Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Almost shocking ! As I was not very satisfied with the quality of my prints, and after experiencing a strange awful printing incident (Wires every where, big melted material blob on top), I started having some sort of concern about temperature readings. I used a very thin thermocouple connected to a pro grade thermometer (Testo 945). […]
Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Open source printers are for ? … They are for mods, hacks and tweaks ! The first obvious modification (not to say immodestly improvement) deals with the cooling air blower in front of the print head. Most the air flow would splits on the Y axis rod, some would re-converge thanks to physic’s law, […]
My daughters played a lot with their “Polly Pocket” in their young ages ! An endless perspective of gaming nicely packed in a hand palm format. Which translates into this portable lab case… in the the Arduino’s world ! Isn’t it cute ? More on the Arduino UNO Portable Lab Case >here<
