Fresh hacks every day
This snippet of Hello World code lets [Nico Ritschel] turn the Pin 13 LED on his Arduino on and off using Siri, the voice-activated helper built into iPhones. The trick here is using the Ruby programming language to get Siri Proxy talking to Arduino via the USB connection. He calls the project siriproxy-arduino. On one end of the hack resides SiriProxy, a package not approved by Apple which is … [Read more...]
It seems like tinkerers are always being tapped to build or repair exhibit hardware. This time around it's [Dino's] turn. He's been asked to alter a light bulb efficiency demo so that it includes an LED option. The idea here is that you crank a generator to power different types of light bulbs. There's an ammeter built in, but possibly the best feedback is knowing how hard you have to crank to … [Read more...]
Perennial Hackaday favorite [Dino] has an article in this months Make magazine. It's an automated ball launcher that allows you to play fetch with your dog without wearing your arm out. The powerhouse inside [Dino]'s ball launcher is a windshield wiper motor powered by an 18 Volt cordless drill battery pack. When a ball in dropped into the hopper, it turns on a switch sending some power to … [Read more...]
[Dino] is about three-quarters of the way through his talking box project. He's completed one of the two boxes, and is showing off the technique he uses to marry motion with sound in order to mimic flapping lips with the box top. You may remember [Dino's] first look at the EMIC2. It's a single-board text to speech module which is what provides the voice for the box. But what fun is that without … [Read more...]
This is the EMIC2 text-to-speech module. You can see from the logo on the bottom left it's the latest gadget coming out of [Joe Grand's] Grand Idea Studios. [Dino] tipped us off about his first experience with a prototype of the board. He's driving it with an Arduino and the video after the break shows that the sound rendering is high quality and the words are very easy to understand. One of the … [Read more...]
[Dino's] project of the week is a backup alarm for your car. This is a feature that has become popular on many large vehicles like SUVs where visibility is an issue when moving in reverse. But it doesn't sound like he was motivated by the need to have this in his own car. Instead, he was looking for something to build using a laser range finder. [Joe Grand] (the brains behind DEFCON badges) has … [Read more...]
Well, this metal suit might not make you a dinosaur, but it would be perfectly possible for you to play one on your computer. Retailing on eBay for a mere $2,397.99 OBO (plus Freight for a 350 pound box), this device was made and used for the motion capture of Ugobe's Pleo Robot. With the right external components (no word on what those are), it would be perfectly possible to get this suit up an … [Read more...]
