Bluetooth
Log from Batteryless Supercapacitor Solar Speaker

Clip it!
Log from Election Countown Display
One of the first orders of the day is to design and 3D print holder clips for the previous hot glued LEDs. Hot glue wont hold up to the elements and temperature changes outdoors, so a mechanical support option is much preferred: How things were...

Engrave conductive materials with a "Wagner Hammer"
Log from Spark erosion: Detailed view, simple machinery
A "Wagner Hammer" or "Neeff Hammer" is quite simple and essentially consists of an electromagnet and a breaker switch. The electromagnet pulls the hammer inward as soon as a current flows through the coil. If that current is interrupted, the hammer falls...

Prototype finished
Log from Window mount for solar panels
Well, that took a while - I can't recommend the shops for the 28 mm tubing system I linked in a previous post.However, the prototype is now in action. It is not really meant to be mounted this high, but the ledge below the panel predetermines that in...

First Prototype
Log from Felini - Revolutionary Pocket-Sized Electronic Lab
The first version of FELINI was a device consisting of 2 larger and rougher circuit boards compared to the current version, and it was not designed with an integrated battery. This means that it could not function without being connected to a laptop,...

Some reading first.....
Log from Skeliwedge

Do I need a PCB?
Log from Choose Your Own GPT
I wasn't sure if I was going to hand-wire this or have a PCB made for it, and after mapping things out I decided that a PCB was certainly necessary. There's over 250 solder points which would have been nearly impossible to do cleanly by hand. The front...
