Fresh hacks every day
[Mike Shegedin] makes full use of an 8-pin microcontroller with this ATtiny13-based dice project. With a maximum of six I/O pins (that includes using the reset pin as I/O) he needed a couple of tricks in order to drive 14 LEDs and use a momentary push button for user input. We're certainly familiar with the concepts here, but it still took quite a while to figure out what is going on with the … [Read more...]
[Gadre] built his own ATtiny project without using any batteries. It's an electronic Dice (or die if you're being critical) which uses induction to charge a storage capacitor to act as the power source. The voltage generator is made from a tube of Perspex which houses a set of rare-earth magnets. At the enter of the tube [Gadre] machined a channel wich accepts about 1500 windings of 30 AWG magnet … [Read more...]
Most of the dice related hacks we run into have to do with pseudo random number generation, but today we saw something different. This sleek looking jumbo die is actually a prize holding box opened by a secret sequence of rotations. Using an accelerometer and an ATmega 328 with a sub-micro servo to control the locking mechanism. Worried about the batteries going flat and losing your treasure … [Read more...]
[Bluewraith] built himself an electronic dice using a 555 timer and 4017 counter. This is a classic project and he enjoyed doing it but wondered about making a 20-sided dice. So he grabbed his Arduino and got to work. A switch on the final project selects between 20 or 100 sides. He used a MAX7219 to control the 7-segment displays, and a standalone AVR chip for the rest of it. If you missed it … [Read more...]
