Ultrasonic range finder using ATMega8515
Posted on: 07 Jun 2012
This project is used to measure the distance using ultrasonic sensors. The ultrasonic signal passes through the atmosphere to a barrier, which we want to measure the distance. Part of this signal is reflected and travels back to the receiver. The time delay between sending and receiving signals are then determined by distance barriers. The […]
Robot Rover Development Platform for Arduino Unleashed by RobotShop
Posted on: 07 Jun 2012
Boisbriand, Quebec (PRWEB) December 24, 2008 RobotShop, the World’s Leading Source for Domestic and Professional Robot Technology, unleashes the RobotShop Robot Rover, the first ever development platform for the Arduino USB microcontroller. The RobotShop Robot Rover, which was designed in-house by the RobotShop Learning Center, is a low cost and versatile platform for robot hobbyists, […]
4×4 LED Display
Posted on: 07 Jun 2012
The 4×4 LED Display was my first project with a two-layer circuitboard layout. The alignment was not 100% optimal, but sufficent. I wanted to make the board as small as possible, so the parts had to be stacked at some places. The square LED’s were painted black on the sides to keep the pixels sharp. […]
microSD ATmega32 Data-Logger
Posted on: 07 Jun 2012
Aim of this project is to present a way to store a large quantity of data into microSD card in files with FAT32 format. Here, ATmega32 is used for data collection and microSD interface. The data is received from in-build 8-channel ADC of ATmega32. One channel is used for reading temperature from LM35 sensor and […]
UV Exposure Unit & Etching
Posted on: 07 Jun 2012
Manufacturing circuitboards containing SMD-parts with toner-transfer is nearly impossible. The thin traces almost never get transferred completely to the copper. One solution to this problem is to use photoresist boards and expose them with UV light. The layout is printed onto a transparency, which is then used as a mask for the photoresist. I got […]
Sims Recycling Solutions to Attempt to Break a World Record at West Chicago Earth Day Electronics Recycling Event

All items brought for recycling will be safely and responsibly recycled by Sims Recycling Solutions. The event will be held on April […]
8×8 Bicolor LED Matrix using MAX6964
Posted on: 07 Jun 2012
For a long time I had a layout for this circuit, but could never build it, because the layout was to small to be made by tonertransfer. So it was the first layout I made with my new exposure unit. It’s quite small, so it fits under the LEDMatrix itself. Therefore only SMD parts are […]
Thermometer using DS1621 and Nokia 3310 LCD interfaced with ATmega8
Posted on: 07 Jun 2012
I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree C, which can be interfaced with microcontroller over two-wire serial i2c bus. It has operating voltage range from 2.7 to 5.5v. I’m operating […]
EPROM Display using ULN2308A microcontroller
Posted on: 07 Jun 2012
Due to university and work it has been a while since the last post. But I just completed a little project that’s worth posting. Several old 27C256 EPROMS were lying around unused. So I thought about a purpose for them. As I also had some 8×8 LED matrices, a little animated display came to mind. […]
