First one assembled
Log from AutoResetRRR
The first device skips the 5V regulator, as I am testing it with a raspberry pi. Everything is red, even the LED. I began to test it for the raspberrry pi as this needs the additional python software required to shut-down the pi safely. I am thinking...

Hardware Prototype started
Log from LiFePO4 House Battery Monitor
After long delays, I got a Raspberry Pi Zero and have wired up some hardware for testing. A pl2303 usb-serial converter gives me a console, and a usb-ethernet adapter is hooked up through a otg cable. A clone of the adafruit ina219 breakout is monitoring...

Next step - RPI4CM
Log from ipodrpi
Gonna start next project on Raspberry Pi 4 CM with good DAC and other features. Can be gaming console with the same internals. Need experts in crowdfunding (to buy modules and develop PCB)

More Console Work
Log from TMD-3: Turing Machine Demonstrator Mark 3
I reworked the frame for the 7" Raspberry Pi Touch Display and integrated it into the existing console.Just four more panel PCB to populate as I approach the finishing line.

Power Domains and Management
Log from Wilcox Gay A46 Internet Radio
For anyone following along, the power domains are: constant 5V supplied via plugged-in AC cord (VDD on schematic) switched 5V to R Pi Zero W via load switch on PCB (V5P on schematic) switched B+ DC and filament AC via volume control switch contacts The...

HACKLET 95 – MORE PI ZERO CONTEST ENTRIES
Log from Hackaday.io Project
We’re well into the second week of the Hackaday and Adafruit ultimate team-up: The Raspberry Pi Zero Contest. The entries have been flying in! As of Thursday evening, we have 70 projects vying for one of 10 Raspberry Pi Zeros, and one of three $100 gift...

ZeroBug Lite
Log from ZeroBug - DIY Hexapod Robot
With the chip shortage still raging on, building a ZeroBug with the rare STM32F103 is becoming increasingly difficult. I was looking for a replacement for a while, even considering an ESP32. But now that the powerful Raspberry Pi Zero 2 is here, an additional...

Pi Plug & Play Prioritised
Log from Flexible Audio Hub
So I realised it would probably be a good marketing / UX decision to make my hub as easy as possible to use with a Raspberry Pi.To that end, I'm going to make the Hub essentially a "HAT". The shape & size may not be suitable, but I can easily make it...

Simply a dead battery, sort of
Log from [mUPS] Minimal UPS for Raspberry Pi
I pulled the UPS out again last night l so I could get at things to investigate the problem. Here’s what I found: The battery voltage dropped to ~2.5V after the Pi started booting.It behaved the same when the Pi was powered directly from the 18650...

Pi Extension board "PiEBridge"
Log from PCB Assembly Desktop Factory
"PiEBridge" is an expansion board for microcomputers similar to the Raspberry Pi (Pi), which is designed to be a helper for the DIY-maker in all his activities - Pi, together with PiEBridge, can perform a variety of functions: universal programmersoftware...

Design modifications
Log from Wooden Pi Handheld
Second prototype made several design changes - Switched from Pi Zero W to Pi 3B+, Required some serious slimming down of the PI. Used better battery and charge circuit, Routed the keyboard PCB in one piece, modified button design to...

First day
Log from HF receive converter for RTL-SDRs and similar
Decided to do a square inch entry with an idea that I've had floating around for a while. A bit of work with Eagle and I have a PCB designed, a bit of work with a browser & spreadsheet & I have a costed BoM.I've tried to design it with hand-assembly...

First things first.
Log from BattMan Pi
As I said in the project information, this project has three phases. First, redesign the circuit to work with the Raspberry Pi. Second, make a PCB design for the new circuit. Third, modify the original BattMan II software to work on the Pi.These tasks...

Good and bad news
Log from LiFePO4wered/Pi
First the good news: after building up my "final" prototype of the LiFePO4wered/Pi board, I was able to do some testing. It seems I managed to improve the efficiency by going to a smaller but less resistive inductor, so now I got a run time of 1:14 with...

Preparing the Pi(e)
Log from Just another Raspberry Pi laptop. Unless...
Get it? Preparing/cooking a pie? Pi?... *ahem*It's pretty obvious that the Raspberry Pi won't fit into the Mac's casing, so I'm going to be trimming it down. If you're interested in learning more about this process, you can look up 'diet pi' (or, of...
