Building an Arduino Smart IC Tester for $25

There’s no question that you can get a lot done with the classic multimeter; it’s arguably the single most capable tool on your bench. But the farther down the rabbit hole of hacking and reverse engineering you go, the more extravagant your testing and diagnostic gear tends to get. For some of us that’s just an annoying reality of the game. For others it’s an excuse to buy, and maybe even build, some highly specialized equipment. We’ll give you one guess as to which group we fall into here at Hackaday.

[Akshay Baweja] is clearly a member of the second …read more http://pje.fyi/QGYzLc

Modern Technology for an Ancient Contest

Certamen is a special class of  high school quiz bowl tournament that’s focused solely on the classics. No, not Austen and Dickens, the actual classics. All the questions are about stuff like ancient Greek and Roman civilization and culture, classical mythology, and the finer points of Latin grammar. Like any other quiz bowl, the contestants use buttons to buzz in and answer the questions.

To win at Certamen, a team needs more than just a vast working knowledge of classical antiquity. They also have to be fast on the buzzer. The best way to do that is to practice with …read more http://pje.fyi/Q0b0vm

Fight a Minotaur with this Gorgeous Handheld

[Jason Carlson]’s favorite game as kid was 1983’s Treasure of Tarmin by Intellivision, a maze game that eventually came to be called Minotaur. As an adult there was only one thing he could do: remake it on a beautiful Arduino-based handheld.

[Jason] built the handheld out of a small-footprint Arduino Mega clone, a 1.8” LCD from Adafruit, a 5 V booster, a 1” speaker and vibe motor for haptic feedback. There are some nice touches, like the joystick with a custom Sugru top and a surprisingly elegant 2 x AA battery holder — harvested from a Yamaha guitar.

The maze …read more http://pje.fyi/PNlXFX
