Updated Winding Jig for Ferrite Cores vs Steel Cores
Log from Electromechanical Refreshable Braille Module
I was initially using 1mm steel cores harvested from paperclips, but experimentally found that the steel core doesn't take well to fast voltage changes, and heats up the coil so much, that I had a few failures while testing operational parameters. So...

"Sunday's Shutter Server"
Log from X-Ray CT scanners get new life
The motor is a Brushless DC, which can mean a lot of things. This one runs on three phases. And it uses hall effect sensors. It took a lot of reviewing brushless motors and motors in general to understand that much, and I still can't drive it properly. ...

Solar Powered LoRaWAN GPS tracker + phone charger
Details from Solar Powered LoRaWAN GPS tracker + phone charger
Our visor integrates revolutionary technologies such as LoRaWAN, Helium network, datacake integration to provide GPS tracking and phone charging using Solar power. It was developed using Fusion 360. All the required 3D and electronics design files are...

Smart HVAC System
Details from Smart HVAC System
The project uses Edge Impulse FOMO (Faster Objects More Objects) custom ML algorithm to detect multiple objects and its coordinates using a compact micro-controller with on-board camera (Nicla Vision). The object detection ML model will use the...

Inference on the Seeed Studio XIAO nRF52840 Sense
Log from AI Audio Classifier Recycle Bin
I've tested different microcontrollers for running the Audio Classifier inference (and DSP). The project initially uses the Arduino Nano 33 BLE Sense for inferencing and Actuator controls. Since now I have upgraded the PCB to include an additional microcontroller...

Assembly
Instructions from TechNIK's Cyberdeck
The assembly is pretty self-explanatory. Provided both cable harnesses are soldered, the following sequence is recommended: (all 3d printed parts are written in bold in the following text) remove all outer keys of the keyboard, insert them into the case...

Front holding structure
Instructions from Camperwagon 3.0 - Eljestmobile
The front will open frontwards using a 20x20 square aluminum frame as door frame and the front part on hinges fasten between it and two U shape 25x25 aluminum beams (one on each side) The idea with the U shape is to make sure rain and wind do not enter...

Electronics Assembly - Commands and Usage
Instructions from Low Cost Universal Tensile Testing Machine
Operating Modes There are five main testing modes that are available in this machine: Slow tensile testFast tensile testSlow compression testFast compression testModulus test The names themselves are self-explanatory except for modulus test. This test...

Safety First!
Log from Gaggiuino for Breville 800ES/B
There are a lot of different versions of the Gaggia Classic, but the versions I find most interesting are those sold in Europe. As far as I'm aware (and I've actually never owned or used a Gaggia machine) the European versions all include a standby timer,...

Input mechanism for the V3
Log from Music32-V2 - Portable music player
Ive been thinking about potential input devices for the V3 design. Previously the plan was to use an external capacitive sensing chip, because the ESP32 doesnt have enough gpio to handle everything and touch sensing is the most sensible to allocate...

Using up some old Qi chargers
Log from Use It Up!
I had a couple of Qi charger circuit board kits I got from Adafruit and from a client project. A small Eureka moment ensued when I read my iPhone supported Qi charging as well as Apple's proprietary wireless charging. For some...

Making the motor/carousel assembly
Log from Low-cost watch parts washer
The heart of this build is a carousel with holes in (for the baskets) attached via a spindle to the motor's output shaft. The motor is attached on top of the jar lid, whilst the spindle and carousel hang down into the jar containing cleaning/rinsing...

Evolution of a Programmer
Log from Cyberdeck SAO
As mentioned before, I decided to put the programming interface into one of the unused (at least, for our badges) pins of the SAO connector. The idea was it would be easier and faster to just plug the SAO into its intended port after assembly, rather...
