“I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself?”

“Microchip PIC now has a USB flash controller in an IC. So you no longer need a USB chip with various components AND a microcontroller. Both components are integrated in one chip. Microchip also sells these chips in DIP package. This makes the job for prototype development and hobby electronics easier.” [Article in German]

“Today, I am going to talk about a revised version of the same project but with all the components specified this time. The new version uses the TCRT1000 reflective optical sensor for photoplethysmography. The use of TCRT100 simplifies the build process of the sensor part of the project as both the infrared light emitter diode and the detector are arranged side by side in a leaded package, thus blocking the surrounding ambient light, which could otherwise affect the sensor performance.”

“This week has just been a torrent of Deathblades work. I’m proud to say that the skate motors are all finished. Well actually, two of them still need their share of custom arc magnets, which I hope to take care of soon through Supermagnetgeorge again. At the least, they can support my weight and I can skate around unpowered.”

“Several years ago, I took a huge leap of faith, decided to buy a small CNC mill, set up a resin casting workshop, and invested months of intermittent trial, error, and triumph to understand and befriend both technologies and document them so that others don’t have to go through all the pain. It was well worth it, to be sure.”

“Deadly, yet adorable, this plush turret from the game Portal talks and responds when you play with it. It senses when you pick it up, knock it over, or walk in front of it. The stuffing and soft fleece skin make it super cuddly, too!”

“Are you artistic? Do you enjoy creating art? Some may think that art is something only humans can make, but what about robots: can they be artistic? They can if you build them that way. In this robotics engineering project, you will build a robot that creates art. And who knows? Someday your robot art may be worth millions!”

“Our project was, to put it simply, a personal informatics black box that you clip onto your belt. As you go about your day your activity, surrounding environment and locations are tracked to produce a report telling you how much time you spent inside and outside. The device leverages off of a system-of-systems providing context-aware analysis for such ubiquitous computing devices.”

“This is the last project that I made during the semester holidays last february. This robot is not equipped with fire sensors, as sensors for detecting a fire is very expensive and not affordable to me. so I use the TV Remote to control the robot motion and put the fire out. to put the fire out of this robot uses a computer cooling fan.”

“Over the weekend, me and a friend of mine, cannibalized a 9 Lira RC car into line a follower. Code in this post covers everything up to [this] commit cf731aedc156f067aa221, refer to this particular commit for this project cause we plan on improving hence code will change. Stuff you will need: 3x QTR-1RC Reflectance Sensor, Ardumoto – Motor Driver Shield and A cheap RC car.”
