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 is the iconic San Francisco race, with tens of thousands of runners (many in costume and some in nothing) running […]

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
Have you ever felt like creating one of those city street time lapses that you see on the internet or recording the blooming of a flower through a time lapse or maybe create a night sky panorama of the milky way drifting in the background? Well, now you can do so with your own custom
The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and construction. If you attempt to use an ordinary ac milliohmmeter containing a kilohertz-range ac excitation source to measure a battery’s internal resistance, you get erroneous results
Dynamic-load circuit determines a battery’s internal resistance Continue Reading
For my latest project, I am diving back into Verilog to create the hardware side of Consolite. For those who don’t know, Consolite is the name I’ve given to my design of a tiny hobbyist game console and associated software toolchain. In my previous posts, I demoed a compiler that translates from a flavor of
Features Simple hardware, using pre-fabricated modules Controls an RGB LED via any recent browser, any operating system WiFi credentials can be configured via browser Software is written as an Arduino sketch Introduction Some time ago I read about the cheap and easy to use ESP8266 WiFi modules and I had to have a couple of

Ever electronic device emits a certain amount of electromagnetic fields and we can use this radiation to learn a few things about the circuit. In today’s instructable I’m going to show you how to build your own electromagnetic field meter using an Arduino. This device can be used to detect mains voltage, static electricity and

Monitor your plants and let them water themselves when they are thirsty. Story Motivation I work in a rather ‘sterile’ office, that was once a server room with raised floors. After several years working in there, I got tired of no windows, no outside light, and NO GREEN things, and decided to bring in one

In this instructable, I’ll go over what a printed circuit board is, where they are used, and the basics of how to make one yourself. So sit back, strap in, and enjoy learning about this very important and interesting method of making electronics! Note: this is an introductory guide. I’m sure that there is a
So, you’re an electronics hobbyist and want a 1GHz* active probe, or a professional and tired of blowing your 2000$+ active probe in sketchy circuits when all you wanted to know are the whereabouts of some RF-signal? Then stay with me!! This Instructable will show you how to build a 1GHz* Fet-based Active Probe, the
