Fresh hacks every day
[Jeri Ellsworth] sent over a 555 design contest entry that struck her as particularly interesting. The Synthanola is a three-channel music synthesizer that accepts input from an old Heathkit paper tape reader. While this hack might seem overly retro, it’s actually an extremely appropriate use of technology, as the Heathkit H-10 and the 555 timer were both popular tech in … Read the rest
Learning about how infrared remote controls work is a great way to expand your electronics knowledge. That’s because this technology is invisible to our eye, and happening faster than we can comprehend without help from test equipment. This tutorial over at Pyroelectro talks about the theory behind how the data is transferred and shows you how to build a couple … Read the rest
[societyofrobots] recently posted an Instructable on how to build a voice controlled robot in just a few hours time. This robot isn’t particularly cheap, weighing in at about $230, but it is a fun project if you have the means. The bot is driven around by a pair of servos, taking their directions from an Axon II MCU. A VRbot … Read the rest
So your house looks like a dumping ground for useless junk? Yeah, we know it’s the hacker’s curse… you just can’t stop salvaging stuff. But follow [Pontazy69's] lead by building something useful out of that junk. He took an old polystyrene box and made it into this fishtank. You can see that the sides and back of the box … Read the rest
The white parts that make up the body contours of this guitar have been 3D printed to meet [Bård S D's] personal specifications. He started designing the pieces last year to add to his Zoybar guitar. Each of the three parts has its own function. The tail piece serves as a floor stand, as well as a hook for hanging … Read the rest
[The Longhorn Engineer] wanted to record some of his virtual shredding sessions so he built this camera mount for a Guitar Hero controller. It holds the camera about a foot below the bottom of the controller, pointing up at the guitar and its player. Since the camera is held tightly to the guitar this produces an interesting effect of … Read the rest
[robomaniac] shows us some serious application of modern technology with his recent Instructable, (the) Arduino-Fart-O-Meter. The wireless device uses a “perfboard Arduino” to read a remote wired methane sensor, and send data over a nRF2401A radio transceiver.
“The data” is picked up by another Arduino / transceiver combo, which then drives a servo motor connected to the pointer. The … Read the rest
