Fresh hacks every day
[Timothy] is honing his microcontroller skills with this electronic dice project. In addition to giving him an opportunity to work on some code, the use of an 8-pin chip provides a design challenge for driving the twelve pips and providing a user input.
The project started off with some $4 strings of LED Christmas lights. He promptly disassembled the … Read the rest
If you needed a reason to dress up for your next Dungeons & Dragons adventure this is surely it. Not only will this attractive wrist adornment go right along with your medieval theme, but the gauntlet doubles as a multi-sided digital die.
Sparkfun whipped up this tutorial which details the build. Yep, they’re hawking their own goods but we … Read the rest
If you’re gaming on the road, or just don’t have a die with the right number of sides on hand, an electronic polyhedral die will be quite handy. [Marcus] built this using a printed circuit board of his own design, and we think an electronically simple project like this is a great way to get your feet wet with … Read the rest
[Anthony] is a big fan of Dungeons & Dragons, but he thought the game would be far more fun to play with an electronic die rather than the traditional fare. Electronic dice are nothing new around here, though we can’t help but like his design.
He wanted to keep his electronic die as small as possible while ensuring it would … Read the rest
[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 … Read the rest
A pair of 6-sided electric dice (original in Dutch, here’s the Google Translate link) was sent in on the tip line for our ATtiny hacks theme. We really appreciate the simplicity of the circuit; it really shows how the complexity of discrete components can be cut down with a simple microcontroller.
The circuit is very simple – An ATtiny26 serves … Read the rest
[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 … Read the rest
