Last year I bought this Etch-Set For Electronic Circuits from Jaycar with the intention of having a go at making my own printed circuit boards (PCBs). I’d had lots of experience working with those experimenter’s Stripboards and Perfboards, which had been more than sufficient for most of the fiddling I did in the past, however […]

Most projects include at least one LED. Before soldering the LED, how can you determine if the color and brightness meets your needs? After that, how do you calculate the correct value resistor? Many years ago, I built a handy compact LED testing tool based on the LM317L adjustable current regulator. (You’ll definitely want to […]

This is a simple video poker game for the PIC 16F628 and a 20×4 character LCD. It’s written in PIC assembly for MPASM. I started the project in 2002. I originally intended it as a birthday present for my brother, who is an enthusiastic if occasional player of casino video poker. This Mark I version […]

18 pin PIC Development Board I have long been playing with Microchip PICs but have always made do without some form of development board. To that end I have designed a basic board that I was hoping to get some input for. I haven’t yet made this board as I am waiting for some kit […]

Now the PCB kit I used described how I could draw my circuit layouts directly unto the copper clad board using an special pen with etch-resistant ink, however lacking the dexterity of an artist I chose to get myself some CAD software for generating PCB layouts. After a bit of research I decided to go […]

Researchers at TU/e have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such […]

A 12hr/24hr LED Clock with display control, uses a microcontroller PIC 16F84A or 16F628A and a few parts. (August 25, 2009) This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it “The ANP LED Clock”. (ANP […]

ARM has brought out a set of IP for top-of-the-range  mobile devices due to launch next year. The IP suite includes: an ARMv8-A-based Cortex-A72 processor, an ARM CoreLin CCI-500 Cache Coherent Interconnect and an ARM Mali-T880 GPU delivering up to 4K120fps performance and console-class gaming, all optimised for TSMC’s 16nm FinFET+ process with ARM POP […]

Last year I started a project to convert my (then) four-year old’s busted Radio Controlled (RC) car into Bluetooth controlled one which could be driven using a smart phone or tablet. The original car, modeled after a “Fast and Furious” Nissan Silvia, was a pretty basic RC with 2-channel on-off (non-proportional) style controls, and while Micah enjoyed […]

The Minibot is a small autonomous robot vehicle that uses phototransistor that can detect lightness patterns on the ground to follow the edges of the dark lines. It has a MC9RS08KB4 MCU, coin cell, motor, and a phototransistor. The MC9RS08KB4 is part of the MC9RS08KB12 series, a family of RS08KB 8-bit microcontrollers. It features a […]
