Adding a turbo readout to a vintage PC case
The hardware for this project includes an Arduino Mega 2560 board and a small OLED screen. Woehlke chose the Mega because he had it on hand, but any Arduino board would have worked. The Arduino receives power from one of the power supply’s 5V rails. And like the real turbo readouts of the ’90s, the Arduino doesn’t measure clock speed at all. It just looks at the LED above the turbo button to see if it is active, then uses that state to determine which number to display on the OLED. For extra flair, Woehlke added a starfield “screensaver” that appears on the OLED 10 seconds after pushing the turbo button.

Deckility handheld PC | #MagPiMonday
Recently, after considering getting his hands on Clockwork’s uConsole, a modular pocket-sized computer, he felt that building his own handheld was more challenging. Snapping up a Raspberry Pi Compute Module 4 (CM4), he also vowed to take advantage of its quad-core ARM Cortex-A72 processor by putting it at the heart of his own homemade device.

A Usable Arduino Debugging Tool
For as popular as the Arduino platform is, it’s not without its problems. Among those is the fact that most practical debugging is often done by placing various print statements throughout the code and watching for them in the serial monitor. There’s not really a great way of placing breakpoints or stepping through code, either. But this project, known as eye2see, hopes to change that by using the i2c bus found in most Arduinos to provide a more robust set of debugging tools.
