I know that the Raspberry pi SW installation is not trivial, there's plenty of google entries for every topic, which I required for all steps I've done. I am also not an advanced Linux user and cannot improvise an install or compilation from source that...
DFRobot was generous enough to send me two of their MiniQ Robot chassis. The chassis have plenty of mounting holes that allow you to add brackets. They come with two motors and wheels, along with two sets of caster wheels to add strength. The assembly...
Since there is plenty of room inside the cat feeder enclosure I decided to mount the Pi and other electronics inside. I wanted easy access to the Pi, so I decided to mount it on the inside of a door which I can swing out. This keeps the wires and electronics...
You probably did plenty of test steps along the way but this was all there was. I am assuming you know how to use relays and have some lights/motors/whatever planned to use with this device so knock yourself out. While there is nothing stopping it from...
Chances are, there is a gunky old nozzle still attached to your printer. Remove it. There are plenty of videos on Youtube that show you exactly how to do this on your specific 3D printer. Do not strip the nozzle's hex profile, and do not twist the nozzle...
The best lines are the network lines Probably someone on the internet said that How big can you make a kite turbine network of networks? The reason for network lines is they can break - and the whole system can continue to work. You can see plenty of...
With a multimeter, adjust the SiPM voltage by turning the potentiometers. Each full turn adds about 250 mV to the output, so you have plenty of resolution here. The potentiometers are connected in series, so you can use either and/or both of them to...
Print the cutting template on a A4 sheet of paper and cut out both bow tie ends. Note that this version has not been tested yet. You can also create your own, e.g. by making use of the scanned bow tie. There are also plenty of other good cutting templates...
The location weather station is the most important part of installation. If weather station is located under a tree or an overhang, the rainfall data measured by the station will not be correct. If you place your weather station in an alley, you could...
If its a new product that has never been seen before or a copy of an old product, a customer will eventually use the thing. Even if it is just for your personal use, write down your needs so you can hit all your goals. For this project I wrote down what...
I'm using GIMP, just because I have used it a few times. It is easy enough to get used to, especially when you can google just about anything you want to do on it. First, I need to decide which colours can be merged into one. I have 4 colours to work...
Set the motor mount retainer on top of the stepper motor and attach with 4 x M3 screws. Press-fit the 5 : 1 sun gear with the motor shaft axle to the stepper motor shaft. (note: the motor mount STL doesn't have the four holes in the plate right...
Step 1: Fill the cavity of the mould with Fimo or a equivalent polymer clay and flatten the clay e.g with a round pice of wood or core follower. To prevent the two clay parts from sticking together while making the key indentation, powder some talkum...

The basic capacitor is done. This next section is how I built a motor drive to remotely position the capacitor. I decided to use a DC motor. Perhaps a stepper is a better idea, but for now I like this design. The motor I chose is overkill. It was...
