Daft Punk Helmet replica finally completed

[Harrison Krix] finished his Daft Punk Helmet replica and posted about it this week. We took a look at his work back in October but he’s come a long way to pull off a legendary build. Take three minutes after the break and see 17 months worth of work. So many skills were pulled together to make this happen; sculpting, mold making, painting, electronic design, mechanical design, and bad-ass-ery. Crammed in along with your noggin are a bag-full of LED boards but the Arduino that controls it all resides outside, in a project box tethered to the helmet. This is a masterpiece of socially-unwearable geek fashion.

Adding mute to a Bluetooth headset

[Jared] often needs to be on conference calls for work during his motorcycle commute. He’s got a bluetooth headset that cancels noise but it didn’t have a mute feature. He cracked open the speaker and microphone portion of the apparatus but there wasn’t enough room for a switch. The base unit which houses the noise cancelling hardware had plenty of room. He added a single pole double throw (SPDT) switch to the positive wire from the microphone, allowing him to disconnect it as a mute function would. He mentions the need to seal the unit with silicone after the hack in order to keep out the elements. We might have opted for a weather-proof switch as well.

This simple hack makes a nice addition to any Bluetooth projects you’re working on.

Teensy credit card reader

Here’s a hack that makes business sense. [PT] recalls last year’s HOPE conference when their booth was using a virtual credit card terminal for purchases that required manual entry of card information. This year they’ll have the same virtual terminal but this magnetic stripe reader will fill it out automatically.

A magstripe reader (reading only, no funny business here) from Mouser grabs data from the card. A Teensy microcontroller board, which identifies itself as a USB keyboard, automatically fills out the virtual terminal from the parsed data. The real question, are his customers comfortable sliding their plastic through a hacked reader?
