5V, 5W Version Posted
Log from LM5161 Based DC-DC Bias PS
I made a 5V, 5W buck derivative that is smaller than the flybuck design but uses the same input/output filter design for low noise/ripple applications. The inductor core is a Magnetics MPP C055048A2. with 38 turns of 24 AWG. Peak efficiency with...

The PCBs arrived...mistakes where made
Log from GNSS module 2.0 - GNSS via Bluetooth
The PCB arrived and they look perfect, not that I had any doubt when ordering at a big Chinese manufacturer. And of course there are mistakes :/ The voltage regulator for USB power to the GPS chip U5 has the wrong footprint. I used a SOT-89-3 foot...

Display side quest
Log from Smartwatch 10 Years Ultra-Long Battery Life
The e-paper display seems like a bad idea, due to extremely high refresh current draw which is unsupported by the small watch battery. I could place large capacitors to buffer enough charge for a re-draw and refresh, however, the extra circuitry required...

Ordered Some More Parts
Log from Motion Controlled Cabinet Light
I decided that once I get this project working well, that I might make several for family and friends that might need something like this. To that end I placed an order for some HC-SR04 (Ultrasonic Ranging Module) and the HC-SR501 (PIR Sensor) modules...

FlexSEA-Plan is an embedded computer used for high-level computing. It boasts a powerful processor and can run an operating system such as Linux. Developing code on this platform is similar to the regular (i.e. non-embedded) software development process....

Firmware development + Front Lights case
Log from Electric mountainboard with CAN bus + Android app
I modified Android application and Control Unit firmware so that front lights can also be controlled (brightness, blinking mode) via Bluetooth. Previously only rear lights settings were being sent from the phone. Now Control Unit receives all the settings...

Firmware update: Menu system and two-week battery life
Log from Color Open Source Smartwatch
I've redesigned the way screens/apps are handled and introduced a main menu. More importantly, I have managed to get the average current consumption down to 350-550uA (1.5mA previously)! Turns out a huge chunk of it - 800uA, was a bug in the TWI (I2C)...

All Your ISA Belong to Me!
Log from DDL4-CPU
Before I began the layout of the DDL4-CPU, I came up with an initial Instruction Set Architecture (ISA) for the design. It went through several revisions as I was designing the boards and refined the components. Here at the last minute as I am...

Log from Hackulator
I ended up using the key combination for On and Mode (it seemed appropriate) to change the mode, which basically is between TI-83 keyboard mode for the TI-83 emulator and Regular mode which allows through various submodes access to just about all of...
