Circuit Sculpture Teaches Binary, Plays PONG

We sure wish we’d had a teacher like [Volos Projects]. He built this beautiful circuit sculpture to teach his students how to count in binary and convert it to decimal and hexadecimal. If you don’t already know binary, you get to learn it on DIP switches and a dead-bugged ATMega328 in the video after the break. Lucky you!

Once the students have the hang of entering binary input on the switches, they can practice it on the four-banger calculator. This educational sculpture can also take text input and scroll it, but it takes a bit of work. You have to look up the ASCII value of each character, convert the decimal to binary, and program it in with the switches. There’s one more function on the menu — a one-player PONG game to help the students relax after a long day of flipping switches.

Funny enough, this project came to be after [Volos Projects] came upon the DIP switch in his parts box and wasn’t quite sure what it was called. How great is it that he learned something about this part, and then used that knowledge to build this machine that uses the part to teach others? It’s surely the best fate that parts bin curiosities can hope for.

Don’t have the patience for circuit sculpture? You can make a pretty nice binary calculator with a bit of paper and a lot of compressed air.

A Mini USB Keyboard That Isn’t A Keyboard

A useful add-on for any computer is a plug-in macro keyboard, a little peripheral that adds those extra useful buttons to automate tasks. [ Sayantan Pal] has made one, a handy board with nine programmable keys and a USB connector, but the surprise is that at its heart lies only the ubiquitous ATmega328 that you might find in an Arduino Uno. This isn’t a USB HID keyboard, instead it uses a USB-to-serial chip and appears to the host computer as a serial device. The keys themselves are simple momentary action switches, perhaps a deluxe version could use key switches from the likes of Cherry or similar. The clever part of this build comes on the host computer, which runs some Python code using the PyAutoGui library. This allows control of the keyboard and mouse, and provides an “in” for the script to link serial and input devices. Full configurability is assured through the Python code, and while that might preclude a non-technical user from gaining its full benefit it’s fair to say that ...
