Bluetooth garage door opener

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.

I’m matching funds for cancer research!

I’ll keep it short: this week when you donate for cancer research, I’ll match your donation (up to a limit of $5000 total for all donations). We’ve already raised almost $8,000 dollars to help stop cancer, but I’d love to get to $10,000 or even higher.

If anyone has ever wanted to take money out of my pocket, now’s your chance! Donate for a great cause and I’ll match you dollar for dollar. :)

Thanks in advance if you can donate to the Dana-Farber Cancer Institute this week. And if you do donate, remember that many employers will match charitable donations! I’m incredibly grateful to everyone who has donated, and I’ll be thinking of you on my multiple-hours run in Boston this spring.

Donate to cancer research!

30 day challenge update: stretching!

I like to set myself different challenges every 30 days. In October 2013, I tried to eat better and exercise more. I did alright on that, but without a specific daily goal, I had a hard time deciding how well I did. I mostly got back into the habit of exercising daily, so that was helpful.

For November 2013, I tried to do a “no work November.” I had enough vacation days built up that I was hitting the upper limit for work, so I took a bunch of vacation in November. My in-laws visited one week, then it was a family member’s birthday, so we took some time off at a resort in Arizona. Then it was back home for a week before spending the week before Thanksgiving in Kentucky with my family.

I learned a few things in my month off:
- I still enjoy reading tech and Google news for fun. It’s amazing (or problematic?) how much time you can spend just surfing the web each day and reading what other people are writing.
- My initial goal was to not read work email at all, but I had to give up on that. There were a few urgent things I genuinely had to weigh in on. I eventually settled for reading work email but trying really hard not to reply unless it was an emergency. I probably ended up writing 20-30 replies over the month, along with passing on spam reports that people emailed to me.
- I realized that I’d gotten in the bad habit of giving friends my work email address, as well as forwarding my personal email address to my work email. Takeaway: keep your work email separate from your personal email. Seems like common sense, but after almost 14 years at Google, things had gotten tangled together.
- A couple good pieces of advice that I failed to heed: 1) remove your work account from your phone, so you can’t check work email or docs on your phone. 2) if you have an “email tab” that you keep pinned on your browser, unpin and close that tab. I didn’t take either of those steps, but I should have.
- I didn’t feel the need to start any big projects, or write any Android apps, or blog a lot. I have a newer Linux computer that has configuration issues; I didn’t tackle that. Mostly I enjoyed reading a few books.
- I’m incredibly proud of the whole webspam team at Google. Things ran like clockwork while I was gone. I’m really grateful to the phenomenal people that fight spam for Google’s users every day.

Which brings us to December 2013. Back in September, I threw my back out. I can still move around fine, but it sometimes hurts if I bend in various ways. So my goal for December 2013 is to do 15-20 minutes of stretching–things like cat and camel–each day to help my back recuperate.

How about you? Are you doing any 30 day challenges?
