How to make a ‘Propeller Display’ using PIC microcontroller

This is my first post Related to Projects and today i will describe ‘Propeller Display’ project. Me and my friend Rushi, we both made ‘Propeller Display’ project during our under-graduation. Below is the photo of the project. Project uses Microchip PIC16F84A Microcontroller. Below is the brief specification for same. 18-Pin, 8-bit microcontroller Operating Speed – […]

Pic 16F676 ICSP programing socket for the PICkit 2 programer

I’m trying to build this dual DC motor module for my robot project And I did not have the space for placing an ICSP pin header on the PCB. So i quickly mocked up this design. Step 1: Geting the parts Well to build the ICSP socket with header for the PICkit 2. We need

Max the Spider – powered by LEGO and PIC microcontroller

So Max the spider visited us in the lab today, and wanted to get into the halloween spirit. “I’d like to drop down on people in the elevator,” he smirked, in a way only a spider could. “I’ve got just the thing,” I winked, and put a little something together. You’re looking at a clear

Open Source Framework for USB Generic HID devices based on the PIC18F and Windows

Introduction If you’ve dabbled with PIC18F microcontrollers and the USB Generic HID standard before (perhaps you’ve even tried my Building a PIC18F USB device project) then you will have noticed that there is a lot of complexity in supporting USB on both the PIC18F and the Windows host-side of things. Getting beyond the basic steps of

Mechanically scanned laser display using PIC17F877

Abstract This application is a very cheap solution for displaying text messages on a solid or semi-opaque surface by using a laser beam. The main goal was to verify the possibility to build a simple and cheap display for displaying large text. The basic idea was to use only one light source (a laser beam)

Led dot matrix scrolling message source code

LED dot matrix scrolling message – 14×5 – source code

I have built various scrolling message badges for instance using the 16F57- 10×5 and 12×5. However, since these chips only have a small FLASH, there is not much flexibility. I don’t really recommend these controllers for a scrolling message. Recently I have started a new project, using small 1.9mm ready made modules, and a 16F884.

2meter (144MHz) amateur radio transceiver

I designed , built, tested and operated a 2m hamradio transceiver that includes all the necessary circuitry, in particular the voltage-controlled oscillator (VCO) + phase-locked loop (PLL) for frequency synthesis, low noise amplifier (LNA) for the receiver front-end, power amplifer (PA) for the radio frequency (RF) output stage and PIC based micro-controller (PIC) with serial

9 Volt Battery Charger

9 Volt batteries extensively used in various electronics measurement equipment. Powering these devices with rechargeable batteries can be a cost effective solution. In this post a simple Lithium-ion 9 Volt Battery Charger design with overcharging protection will be presented. Charger is based on PIC16F876A microcontroller and uses its A/D module to monitor current flow into

Car battery charger with PIC12F683

This time I’m starting off with a device I already built, unfortunately there won’t be any photos from the actual build, just a quick article on how I imagined it and how it works. A short story about how the whole thing started My uncle has a nice little place at the countryside at about

Motion Activated Led Dice using PIC16F688

Introduction I’ve always wanted to build an electronic led dice, but something different from what we see on the internet. Making it motion controlled… now that’s new! Many new cell phones that have accelerometers built in also have dice games. These dice move when shaking the cell phone. My Led Dice project will
