DC-motors (Part 1)

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 […]

Last minute Xmas present… a storage box!

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 […]

Ultrasonic scanner (Part 1)

Part 1, 2 And now, something completely different : here is arduinoos’s ultrasonic scanner ! This ultrasonic scanner results from the combination of two main components: an ultrasonic sensor and a stepper motor. Both have already been covered in this blog (here and there). Both component form the head of the scanner which is screwed on top […]

Amazing 3D printing

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” […]

Stepper Motors (Part 6)

Part 1, 2, 3, 4, 5, 6, 7 This post is about an other driver module which is very popular in the world of robots and 3D printers. These modules features the DRV8825 Stepper Motor Controller integrated circuit made by Texas Instrument (Datasheet available from >here<). Although many clones exist, it looks like Pololu was at the origin of this […]

3D Printing (Part 10)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 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 […]

3D Printing (Part 9)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 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 […]

FreeCAD (Part 1)

Part 1 For various reasons, I decided to investigate the field of open source CAD software for designing and printing mechanical parts. So I spent some time surfing the web for CAD applications and found a dozen of software which are topping the hit list. Blender software happens to be trusting the top of this list. A couple of […]

Make of the day

Back to the 3D prints again with a spectacular tourbillon ! A must see for all fans of clocks… and 3D prints And that’s not all, Christoph LAIMER put all the stl files on thingiverse !  

MicroFAN (Part 1)

Part 1, 2, 3 We gained quite a lot of experience after printing few kilometers of ABS on our Makerbot 2x. Controlling the temperature inside the cabinet solved a lot of problems. After few attempts, we decided to modify the printer by adding a fan on top of the transparent cover. The fan is turned […]
