And now, dear brothers and sisters, one final thing. Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise.Philippians 4:8, New Living Translation
Fixing USB-C charging on the PowKiddy V90 for $0.01
The PowKiddy V90 is an awesome little Linux-powered handheld gaming device. It's reminiscent of a Game Boy Advance SP, and it is capable of emulating most GBA games, in addition to many other consoles including NES, SNES, Genesis, and even some PS1 games!
I love mine, but it's not without it's flaws. The Miyoo custom firmware fixes many of it's issues, but it's inability to charge from a standard USB Type-C ports is a hardware bug. So, it's time to break out the multimeter, soldering iron, and USB-C specification!
DIY ESP8266 ESP-01 Programing / Test board
NodeMCU and other ESP8266 modules are starting to become very popular because they offer an embedded development platform with a CPU+RAM+Storage+WiFi all in one for (considerably) less than the price of an Arduino. There are a number of breadboard-friendly modules with all pins exposed (and more coming soon.)
However, this post is about the breadboard-unfriendly ESP-01 module. It only has two GPIO pins (four if you include the TX & RX pins), but it's smaller and most importantly, cheaper.
Using an Arduino and an IR Shield to connect a TV and Sound Bar
"Snatching defeat from the jaws of victory." That summarizes Samsung's implementation of HDMI CEC ("Anynet+") in their "Smart" TVs - everything works except the power button.
However, with help from an Arduino and an IR Shield, I was able to add in the missing parts and make things work properly.
