DIY bike helmet fan

From the MAKE Flickr pool

Matt outfitted his headgear with some quick-n-dirty AC –

I was bored one day at NYCR and started playing with my rising collections of motors.

Ended up stuffing an 18v motor into my bike helmet and putting two 9vs in series on it. Runs awesome. Surprisingly effective as a cooling apparatus and even more surprisingly effective as a fume buffer.

Probably not very safe in an accident though =P

Consider it an early prototype – fume buffering == quite welcome for urban usage. See the original photo on Flickr.

    Can you guys update this post with pics of a dead biker with a fan motor embedded in his brain when this idiot takes a header while wearing this unsafe safety equipment?

    Probably not safe in an accident? Ya think?

  2. Jeremy says:

    Yes, this is most certainly NOT safe. It’s bicycle saftey month, why is something this dangerous getting posted at all?

    chillax people – Matt used some spare parts to test out an idea. If you read the relevant text you’d know this is not considered a road-worthy device.

    You could use that fan to cut an electric motor diameter hole in your skull. All you gotta do is wear that and have your front brake lock up at high speed. I bet you could make a solenoid to lock up that brake randomly.

    “Not considered a road worthy device” huh? I think it’s a terrific evolution driver.
