Patching guitar amp firmware

Michael Forney has been having a lot of fun with reverse engineering lately.

I was looking over the service manual for my guitar amp, a Yamaha THR10c, and saw references to a UART header in the schematic, I got excited. I wondered if anything cool was hiding in there. Next to it was a JTAG header. I knew next to nothing about JTAG, but had heard the name before associated with hardware hacking, so maybe that would be useful as well.

This project was very satisfying since I went into it without knowing if I’d succeed or how I’d even go about attempting it. There was a lot of head banging and staring at gibberish code for hours, which made it all the more rewarding when things started to click. Sometimes it’s worth it to take on a challenge like this, even if you think you might fail.

See the details in the post here and the code on GitHub.

What toys have kids played with throughout history?

Fun, recent video from TED-Ed that reviews the history of children’s toys – ranging from whistles, wheels, dolls, and beyond:

Archaeologists have found material, visual, and written evidence for toys across the ancient world. In 3000 BCE Anatolia, miniature toy carriages raced through the dirt. In the Indus Valley a thousand years later, a toddler giggled at the sound of their terracotta whistle. So, what other playthings have delighted us through history? Trace the ancient origins of toys, games, and play traditions.

Immigrant Heritage Month 2026 #ImmigrantHeritageMonth

Happy Immigrant Heritage Month. Immigrant Heritage Month is an opportunity to celebrate the richness and diversity immigration brings to the United States.

From NYC Mayor’s Office of Immigrant Affairs:

SFF Satires of Modern Tech Culture

Reactor Mag shares five satires that center modern tech culture.

Speculative fiction has always had a love/hate relationship with technology; whether it’s the “don’t play God” message of Frankenstein or the dehumanization of industrialization depicted in Metropolis, some of the earliest works in the genre have turned a skeptical eye on emerging tech.

But technology is one thing; tech culture is something more specific.

Arcade Fightstick #AdafruitLearnGuide

Hadoken! Build a custom arcade-style USB fightstick in a 3D printed case using an Adafruit KB2040 board and GP2040-CE firmware. You can use it to play games on consoles, such as Switch, PlayStation, and Xbox, as well as Raspberry Pi-based RetroPie emulators and PC/Mac/Linux computers.

This joystick and arcade buttons are just the start — you can add NeoPixel LEDs for dramatic, per-button lighting effects and an OLED LCD screen for settings and diagnostics.

Check out the guide from John Park.
