Recently I moved to a new house, finally I have more space to run my blog. Also, I am doing a bunch of DIYs around the house, like installing this 3-way dimmer switch (to save money on energy and also looks better than old switches).
So, I’ve started a new blog called HouseDIYHowTo.com to focus on these cool House DIYs and HOWTos, you can check out my very first blog post on how to install 3-way
DSLR videography has literally exploded in the last couple years and I am a huge fan (you can read up on my DSLR videography recommendations here); here’s a great hack that can let you trigger video on your Canon DSLR by hacking the IR controller with Arduino so you can turn the video on/off from up to 150-300 feet range.
I had a problem that I needed to solve:

Need to add eye-movement detector for your next project? Check out what Luis Cruz (a senior in high school) did, a low-cost DIY eye-movement detector. This is amazing, not only that he was able to do it for low cost but this kid is simply GENIUS!
The human eye is polarized, with the front of the eye being positive and the back of the eye being negative. This is caused by a concentration of negatively charged nerves in the retina on the back of the eye. As the eye moves the negative pole moves relative to the face
Do you have a Viewsonic G Android tablet? If you do, you probably are saddened by the fact that it doesn’t have GPS on it, meaning you can’t pinpoint your location precisely with 30 feet (cellular location should work though).
If you absolutely need GPS on your Viewsonic G tablet without adding a bulky GPS unit on it, the Viewsonic G tablet actually comes with a slot for GPS, you just need to find the parts and solder it yourself. You can read up all the full p
Here’s a really funky project Jeremy Cook invented from scrap parts incluing his old RC car. The result? Really creepy box that sorta comes alive. Muhahahahaha.
This reminds me of the World’s Most Useless Machine, only a bit more creepier.
Want to dominate the world? Check out this nifty DIY World Control panel that lets you control the world(sorta) with its special buttons.
This could be great toy for your growing-up James Bond and communist toddlers.
My son Harlan and his friend love to play “agents” and he asked me if we coud build “a panel that has a bunch of switches that turn on some random lights”. We worked on it for about 3 weeks, and this is what we came up with.
I’ve been going to Maker Faire almost every year (except this one) and Google went big this year and launched their first Maker Faire booth, exhibiting cool stuff like their SKPR Hexpad Robot and Nexus S phones launched into space with balloons.
What excites me the most is the conversion of Android and Arduino, which brings
Here’s a fun way to display how much traffic your router is serving by hacking OpenWRT by adding a bit of code.
(For those of you who don’t know, OpenWRT is an open-source aftermarket operating system for routers that you can install to your router to customize it. There’s also DD-WRT, which is similar. I’ve personally got DD-
I2C is a great way to connect multiple devices for simple networking communication. Of course, because I2C is not encrypted, others can easily read the info by using an I2C sniffer.
If you want to make such an I2C sniffer, there’s a great guide with source code for Arduino but come to think of it, I can’t really think of any uses for this right now(I know it will hit me after I write this blog post) but it can help you learn more about Arduino and I2C. (
You can adjust the capture windo
I used to deal with many touch controllers but they cost way too much money as it comes with a touchscreen and all the shebang. Well, if you want to make a dead, simple touch-sensor controller, perhaps for your latest backyard project, there’s a bunch of low-cost chips you can use now, and here’s a great example you can follow with video demo below:
