Adding Sockets for External Connections
Log from Vintage Toy Synthesiser
(Original post date: 06/03/16)Even though I ended up constructing a brand new front panel for the toy piano for this project, the rest of the enclosure of the vintage toy synth will be using the existing piano enclosure. Apart from the front...

BRAAAINS!
Log from Prism
Of course the first thing that comes to the average makers mind when they want to add smart connectivity to something is the venerable Raspberry PI. These boards are great, but almost impossible to find in quantity and definitely impossible to buy at...

It started to work
Log from JVC to Clio
The first version of the working code. Let me mention here that this is my first project with Arduino and I never used c++ before. But I was intent and did not give up. I will clean the code but at least it works well. There are still some unused function...

The Stepper Motor Driver Board
Log from SCARA Controller
The Stepper Motor Driver Board Here is the Stepper Motor Driver Board: Almost no documentation in the Internet on this board! It is cheap and I have used it before. Mapping/tracing the Nano pins I get: RX - Serial Receive (pin provided but not...

Hand Assembly
Log from CAT Board
I finished putting most of the SMD components on the CAT Board. Mostly bypass caps (around forty of those). I've left off the through-hole stuff since that isn't needed for the immediate tests.Here's the front and back:Initial testing starts tomorrow:Check...

Part 2: Assembly
Log from Light Alarm Arduino Shield
I have successfully assembled the project by hand, but currently I am exploring pcb assembly options among the PCB manufacturers. This will enable the small surface mount parts to be soldered on while the larger parts can be provided as a kit for those...

BQ25504 Working Like It Should
Log from Ultra-Low Power LiPo Charger via Energy Harvesting
15 July 2018 First a word about packaging. I designed the BQ25504 breakout board to be as small as possible because I had in mind the idea that it would become part of an integrated (hybrid) power source. That is, the LiPo battery, solar cell, and BQ25504...

Numerically Solving the 1D Transient Heat Equation
Log from RepKiln
In an earlier log we looked at the steady-state conditions to get an idea for how hot the inside of the kiln would get. This helped us get an idea for what thermal conductivity, wall thickness, and heater wattage were acceptable for getting the kiln...

The Shield PCB (and a solved mystery)
Log from Kerbal Spaceship Potato
The idea with the shield was to host the analog multiplexers and some of the lamp test electronics, as well as to break down the pin connections in to logically sensible headers. The schematic is on github. Here's the board:The connector in the top left...

Change all the things, more battery tests
Log from LayerOne 2017
Last week we did the battery tests using the 800mAh "iPod' battery we have used before, it is cheap and easily available, the results were about two hours running everything, I posted the data earlier. That is not great, the conference is 3 days usually...
