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,…

The Fan Controller Wrapped Up
Yesterday I found some time to put the fan controller in a casing. I used a very cheap no-name case with the dimensions 130 × 68 × 44 mm. First I drilled some 2.5mm holes into the lid, and fastened the Arduino board on it using M2.5 spacers. You see the bottom of the case in the…
The Five Light Spheres Project
I just published the guide for the five light spheres project. It is the perfect decoration for this Winter. The spheres always display a nice color combination and blend from one color to the next. It is a quiet and artful decoration. Continue reading on the project page
Fan Controller Project
Recently I had the problem some expensive components did overheat in my server rack. The ventilation was not optimal and I had to install additional fans. Because this rack is in my office and I like a quiet working place, the ventilation had to be as quiet as possible. First I thought about buying a…
Outmoded Sequencer Part 2 Ready
I just finished part 2 of the project description for the Outmoded Sequencer. In this second part I describe the steps from the prototype to the final device. I copied the preface from the page after this link . Outmoded Sequencer Part 2 (Preface from the project page) Building the Outmoded Sequencer was a really…
Outmoded Sequencer Live Demo Video
Today I made a short live demo of the Outmoded Sequencer. I just added briefly some audio effects at the end of the video, so you can hear the real sound of the device. Adding effects is a really great way to turn the beep sounds in interesting music. You can also see the connection problems…
Outmoded Sequencer Finished!
Hurray! I just finished the final Outmoded Sequencer device. The tuning of all frequencies was way faster than I expected, because I used a new method. Have a look at the following photo gallery before I tell you some details. You can see the device is build like a control desk, with the PCB a…
Video: Assembling Final Outmoded Sequencer PCB
Here a short update on the progress with the final Outmoded Sequencer project. I did the whole assembly of the final PCB and connected everything. You can see part of the soldering process in the following video: I accidentally cut a route on the bottom of the PCB, so I had to fix this with…
Building a Magnet Matrix
I did many tests with the Outmoded Sequencer how to use steel balls as switches. While this is working very well from the electronic point of view, one problem was the steel balls tended to fall of the PCB easily and roll under furniture. To hold the small steel balls into place I am building a…
The Final Outmoded Sequencer PCB
The final black and gold PCBs for the Outmoded Sequencer arrived. They really look great with a nice contrast between the solder mask and the silk. The surface is somehow glossy and the routes are barely visible under the black solder mask. Now I really hope I will not find any further problems with this…
