Filear.com posted a cool hack that can be done in an afternoon if you have the parts handy. The author built a DIY oscilloscope using an Arduino Pro Mini and the LCD from a Nokia 3310. The Arduino is wired up to sample from an ADC port and writes those values to the screen to create a waveform. Two potentiometers control the sampling speed and input voltage for approximate time and amplitude scaling just like the real thing.
Our friends over at Make magazine put together some awesome projects, and this is one of our favorites. Last year, hacker extraordinaire Matt Richardson released this Arduino project that will monitor your TV closed caption signal for a list of keywords and mute the television when it finds a match. From his description on Make’s site:
I don’t know about you, but I’m a little sick of hearing about the same people on TV over and over again. I came up with this Arduino-based solution to mute my TV so that I don’t have to hear about Donald Trump’s feud with whomever or Charlie Sheen’s most recent rant.
Like hacking? Like cars? At EngBlaze, we’re pretty fond of both of these things, which is why we enjoy seeing creative ways to hack your vehicle. The following projects are a few ideas if you’re looking to insert some DIY hardware into your ride (or perform surgery on an unsuspecting friend’s). Here are five of our favorite ways to hack your ride and make it stand out from the crowd.
Dave has created a Christmas monster and one of the most complex and creative DIY ornaments we’ve seen. He started with a Christmas tree drawing, converted it to a PCB, and designed in 15 RGB LEDs to provide twinkling multicolored cheer during the holiday season.
“So what”, you say. “Let me search Instructables for you and hand you a list of 1,000 other DIY electronic decorations. Stupid EngBlaze”.
Not so fast, folks.
This article explains, step-by-step, how to set up the AVR Studio 5 IDE for use with Arduino projects. It also includes some background on the pros and cons of working with AVR Studio, notes on general setup for working with Atmel devices, and a few other tips we’ve picked up along the way. Feel free to skip around to the sections that interest you.
Building on our theme of cellular hackery, Dave has a three part series on his blog dedicated to the creation of a remote start system for his car. What’s the catch, you say? Oh, no catch, no catch at all… except that he wired his remote start to work via cellphone input, so he can give his whip a call before he leaves work and climb into a warm car immediately upon arrival at the parking lot.
