As you read in my last post about the pet-feeding device project, there was an issue with the fill sensors. The lines from the 3d-print transferred the light directly to the sensor and made a useful measurement impossible. One of the solution to this problem is a small gap between the LED and the sensor….

MicroMaTch Connector to Breadboard in 5 Minutes
Ordering a board with perfect spaced pads to use an SMD connector takes a few days of patience unless you live near a PCB prototyping facility. With striped prototyping boards, you can stick a MircoMaTch or similar connector into your breadboard in under five minutes. 😉 First cut a small piece from the prototype board….
19″ Rack Fan Controller [1/2]
When I migrated several servers into a new server rack, I put my Arduino Uno based fan controller into a new enclosure. Not a great solution, but good recycling of this existing project and way better than the built-in, on/off temperature controller. Now, when the rack’s space got low, I had to find a better…
How to Create a Prototype Connector from a Pin Header
In order to test the input panel, I had to connect the 14 lines to the test setup on a breadboard. Just using a pin header was too flimsy for me, because I often reuse these test connectors on different breadboards. In this short article, I explain how I made it into a solid connector….
Build a 3D Printer Enclosure
Today, something slightly off-topic. This post is a short tutorial on how to build a heavy and solid 3D-printer enclosure. It uses a fully parametric design, where you can adjust the important dimensions – therefore it should work with a wide range of 3D-printer and materials. Update 1: Added some photos, illustrating the process.Update 2:…
