Open source binary wristwatch

Tuesday, March 10th, 2015

Jordan aka njneer made this cool binary watch project, that is available at Github: I’m pretty proud of this project; the clasp is a ribbon cable that doubles as the programming interface for the PIC microcontroller that drives everything. The time is displayed with superbright LEDs that are blinding at 15 mA, which...

Stand-alone inductance meter update

Friday, February 13th, 2015

An update on Lukas' stand-alone inductance meter project we covered previously: From a high-level point of view the new software is very similar to the Arduino sketch I wrote for the Inductance Meter Shield. If you look a bit closer, you’ll notice some differences for several reasons: This project uses an entirely different microcontroller:...

PIC Micro Modbus

Thursday, December 11th, 2014

Chas over at PNW/Electronics has been working on a PIC Micro MODbus project: MODbus is a older-than-dirt communications protocol for industrial process/power controls. It’s generally seen in the wild as MODbus/RTU which is a RS-485 protocol ran at 9600 or 19200 baud. Of course there are a ton of variations and...

Nokia 5110 screen module with PIC microcontroller and Oshonsoft

Thursday, October 16th, 2014

Chris Holden made a font library for a Nokia 5110 display using a PIC microcontroller and Oshonsoft. He writes: Having left the 1980's behind, we decided to write our own "libraries" to write text onto the Nokia 5100 display, using a PIC microcontroller. The code below was written for a 16F877a...

Steam turret tank R/C controller

Monday, September 29th, 2014

An instructable for a PIC based R/C servo controller by Steamhobby: The controllers capture the R/C receiver output, optionally manipulate the samples, then regenerate new servo control signals. As such, they greatly enhance what is possible with cheap servos.  They were created for my Steam Turret Tank Instructable. Via the contact form....

Frequency counter with PIC16F628A

Tuesday, September 23rd, 2014

xristost blogged about the frequency counter module he made: First of all I wanted a PIC microcontroller to do the whole job without any additional ICs. Also I wanted to use the the familiar 16F628A, but because one of the portA pins (RA5) can be used only as input I was short...

Chipstomp assembly – Analogue side

Friday, June 6th, 2014

We previously covered Catmacey’s Chipstomp digital side. Now he built the Chipstomp's analogue side: It’s done.  I’ve assembled the analogue side of the Chipstomp and finally have a fully working device.  There were no errors to fix this time which was a nice surprise.  Just lots of fiddly 0805 surface mount components to place....
