Leon’s Mini Random Number Generator (mRNG) using pic microcontroller
Posted on: 28 Jul 2016
Sales Pitch Are you confused by choices? Who isn’t? There are just so many things to decide. White, rye, or wheat? Pinstripes or polka dots? Feast or fast? Well, don’t worry because help is on the way! I’m introducing the world’s first, portable, hand held, decision maker powered by truly random numbers. Sure, my competition […]
Inside the tiny RFID chip that runs San Francisco’s race
Posted on: 28 Jul 2016
Inside the tiny RFID chip that runs San Francisco’s “Bay to Breakers” race How does a tiny chip time the runners in the Bay to Breakers race? In this article, I take die photos of the RFID chip used to track athletes during the race. Bay to Breakers, 2016. Photo courtesy of David Yu, […]
BlinkLED
Posted on: 28 Jul 2016
A BlinkLED is a LED that has its own PIC microcontroller. Blink patterns and blink rates are programmable and BlinkLEDs can be used individually (for LED Throwies) or in strings for holiday or special lighting. I made these because I wanted to trim my Christmas tree with individual blinking lights. With the BlinkLED, I can do that […]
Two PIC pins drive six LEDs
Posted on: 28 Jul 2016
This Design Idea demonstrates a new method of driving six LEDs with only two I/O lines from a microcontroller, and so is particularly suitable for any pin-limited chip. It uses a pair of I/O lines combined with a pair of complementary bipolar transistors.More than one LED can appear to be lit by multiplexing. A previous […]
Product How-to: Ultra-low noise linear regulators for powering PLL/VCO and clocking ICs
Posted on: 27 Jul 2016
Wideband communication systems usually require an ultra-low noise regulator to power the VCOs and PLLs. The regulator must also be able to reject any ripple presented at its input. In a typical system, an ac input is converted to an isolated dc supply rail, –48-V, for example. This rail is then converted to an isolated […]
World’s First 1,000-Processor Chip
Posted on: 27 Jul 2016
A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis, Department of Electrical and Computer Engineering. The energy-efficient “KiloCore” chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors. The KiloCore was presented at the 2016 Symposium on VLSI […]
RGB LED Color Cycling Circuit
Posted on: 27 Jul 2016
How to re purpose a the RGB LED color cycling circuitry from a Glade LightShow air freshener. I was in the process of creating a red, green , blue color cycling circuit based on a PIC microcontroller when I spotted the Glade LightShow air freshener. I wanted to know if it could be hacked up […]
Contest for people who bought the 3Drag or K8200 printer
Posted on: 27 Jul 2016
Trying to figure out what kind of cool stuff you can create with a 3D printer it’s not always easy if you just look to a magazine talking about it or hosting an advertising page: to fully understand what a 3D printer can do for you, you need to start printing. No coincidence that those who can “get […]
The Boss Box Bot
Posted on: 26 Jul 2016
Welcome to the Boss Box Bot instructable, or as we like to call it, the Bo-Bo Bot. The Bo-Bo Bot was designed to use extremely low cost materials to allow people to construct a robot without high-priced kits. Our Bo-Bo Bot will be made using various tools such as AutoCAD, Corel Draw, and a laser […]
