Minimum Viable 1-D PONG

What makes a game a game? Like, how do we know that we’re looking at a variation of PONG when confronted with one? And how do we know how to play it? [Bertho] sought to answer this question as he designed what is probably the smallest-ever 1-D PONG game. His answer involves charlieplexing LEDs, using a voltage divider to save I/O pins, and a couple of AAAs that should last for a long, long time.

[Bertho]’s Minimum 1-D PONG, or m1dp for short, puts an ATTiny85 through its paces as gameplay quickly progresses from ‘I got this’ to ‘no one …read more

Building Badges The Hard Way

What’s a hacker to do to profess his love for his dearest beloved? [Nitesh Kadyan] built his lady-love this awesome LED pendant – the LED BLE Hearty Necklace Badge.

An HM-11 BLE module provides connection to an Android mobile app. Two 74HC595 shift registers drive 16 columns of red LEDs and a ULN2803 sinks current from the 8 rows. The power section consists of a charger for the 320mAh LiPo and an LDO for the BLE module. All the parts are SMD with …read more

Hackaday Links: February 5, 2017

A lot of people around here got their start in electronics with guitar pedals. This means soldering crappy old transistors to crappy old diodes and fawning over your tonez, d00d.  Prototyping guitar pedals isn’t easy, though, and now there’s a CrowdSupply project to make it easier The FX Development Board is just that — a few 1/4″ jacks, knobs, pots, power supply, and a gigantic footswitch to make prototyping guitar pedals and other musical paraphernalia easy. Think of it as a much more feature-packed Beavis Board that’s still significantly cheaper.
