Today I made a Bluetooth garage door opener. Now I can open my garage from my Android phone. There’s a short how-to YouTube video from Lou Prado. Lou also made a website btmate.com that has more information, and you can watch an earlier howto video as well.
The project itself was pretty simple:
- Acquire a Samsung HM1100 bluetooth headset (the Samsung HM1800 also works). You can buy these cheap from Fry’s or eBay. I got mine on eBay for $10-$15.
- Crack open the earpiece on the Bluetooth headset and solder one of the earpiece wires to the base pin of a transistor. Solder red and black wires to the other pins of the transistor.
- Connect the red and black wires to the garage door opener. It turns out that most garage door openers are built to allow easy insertion of wires, which is nice.
That’s more or less it. My soldering was ugly as sin–too ugly for me to even post a picture. And rather than leave the house for some heat shrink tubing, I just left bare wires on the transistor, but everything works fine.
Lou wrote a nice Android app that’s free to install and then pay-what-you-want for a license. Then it’s just a single button to open or close the garage door. In theory, I could use Tasker to open the garage door automatically when I get home.
It’s not quite as sexy as Brad Fitzpatrick’s Android garage door opener, but it was a fun little project for a day.
