Simple GAL Programmer

It's very easy! This is a simple GAL programmer that hobbyists will able to use the GAL very easy. Building costs are less than 1/10 of cheaper GAL programmers. This is good for parsonal use. And added an optional function to program to the Microchip's PIC with using a socket converter. Programer Specifications Supported Device     Lattice Semiconductor Corp. GAL GAL16V8A/B/C/D GAL20V8A/B/C/D GAL22V10B/C/D ...

Chemoelectronics: Nanoparticle Diodes and Devices That Work When Wet

Whether they’re for sensors in artificial skin that demands flexibility or for wearable electronics where the circuits must withstand our sweat, silicon-based chips aren’t always up to the task. Now, an international research team has developed a way to fabricate flexible, water-loving logic circuits and sensors without the need of semiconductors. Instead, what the researchers have done is coat gold nanopar ...

LED Heart PWM Fading using PIC18F252

With my Grandma's birthday fast approaching I wanted to put something together that was not too complicated but still sweet enough to make for a cool widget gift. Since fading LEDs never seem to go out of style and grandmas always love to see a heart, putting two and two together here was a no-brainer. The concept for this small birthday present was to create a small heart shape with red LEDs and then to dr ...

An AVR microcontroller based Ethernet device

Ethernet has traditionally been a quite complex interface. All Ethernet chips until today had 100 pins or more, where difficult to find in small quantities and difficult to use from a small microcontroller with little memory. Microchip has changed the world with their new ENC28J60 Ethernet chip! The ENC28J60 is a small chip with 28 pins only and has a SPI interface which is easy to use from any microcontrol ...

BOMs Away! – BOM/Component manager for KiCad

IMO, KiCad is one of the best EDA tools out there, with just one major problem: Bill of Materials management is rough. If you make more than 1 board a year, you probably know how frustrating it can be to get everything together for an order. There are multiple ways to export a BOM (each with their own ups and downs), and the process of selecting and entering components is excruciatingly manual. You can of c ...

Making a simple clap switch using PIC12F683

A clap switch is a fun project for beginners. It switches on and off electrical appliances with a sound of clapping hands. Today we will discuss about making a simple clap switch that operates when it detects two clapping sounds in a row. It uses an electret microphone as a transducer for converting a clapping sound into an electrical signal. The microcphone output is amplified by a transistor and is then s ...

Simple Power Guard – PIC12F683

This is a very simple and accurate power guard circuit. This circuit is useful to guard the electronic or electrical devices from mains transients and spikes. Very high spikes can develop at power on due to sparking in the switch and more serious effects occur when power resumes after a power failure due to high magnetic field in the distribution transformer. This will damage your device permanently. To avo ...

XMOS shipping hi-res audio

XMOS is shipping its  xCORE-AUDIO processor family and sampling its Gigabit Ethernet enabled xCORE-200 multicore microcontroller family.  “There’s a big trend for much better audio content,” XMOS CEO Nigel Toon told EW, “there’s a backlash against MP3. They’re going to much higher quality helped by the fact that  you can now transfer big audio files. Sony is pushing hi-res audio DSD digital streaming. The m ...
