“The Shrimp circuit is an Arduino Uno substitute with a component cost of around one tenth the price of official Arduino boards. You can hand-make the circuit on breadboard or stripboard, learning about the components as you go, and remix the circuit freely for your needs.”

“Received the parts a couple of days ago and since then have assembled the quad in what little time I had away from work. I’m going to run through the physical build process in this post and give a detailed rundown of every part that was used.”

“Here at Nomi Design we have a fair amount of experience writing Arduino Libraries. So we thought we would share with the world our techniques for writing code into simple , clean, and easy to use Arduino Libraries.”

Thanks to a strong showing of support at the Kickstarter Project that we hosted 3 months ago, we raised enough money to continue with PyroEDU’s second course: An Introduction To Digital Electronics. Just like the first PyroEDU course that we hosted, this course will be available on several open-access education sites (like uReddit) for you to follow along with, in addition to being hosted here at PyroElectro.com. So what are you waiting for? Go sign up and get ready to learn about digital electronics!

“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!”
