Regular PyroElectro readers probably noticed a new navigation tab was added recently to our website: Learn. For quite some time we’ve been wanting to create a set of organized, entertaining and educating video courses which gave way to PyroEDU. Our first course is An Introduction To Modern Electronics, and the first lesson: The Introduction has just gone live.

“The project is about design and implement a device that can hear a Morse code through a microphone and translate the to text. the text will be displayed on a 2×16 LCD screen, so the device can only translate 32 character [aA-zZ 0-9] at a time .We use an op-amp to amplify the sound signal, couple of capacitor to filter out the some nasty frequencies and an ATMega8 as processing unit.”

“This project describes an open software open hardware pH meter using an Arduino/Freeduino board. In other words, this is an electronic circuit to be connected with a glass electrode pH sensor.”

“I decided to design and fabricate a Botanicalls clone because I also wanted to measure ambient light, temperature, and humidity in addition to soil moisture levels. It also gave me a solid reference point from which to explore a software (EagleCAD) and process I had no prior experience with.”

“A pixel artist friend of mine wanted a mouse to try his skills on a real C64. I thought I could help him by making an adapter that would allow a regular PS/2 mouse to be used with a Commodore 64. The most popular and supported C64 mouse is 1351 mouse which uses analog capabilities of joystick control ports to send movement data.”

“Sometimes I just get this idea in my head, and no matter how stupid or impractical it may be, I’m not going to stop until it’s done. …so I figured it was time for a gratuitous display of silly engineering. And with that, I’m quite pleased to present the world’s first overclocked, liquid cooled Arduino :-)”

“It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments. It’s designed to help a vision impaired person to navigate complex environments.”

“In this article we will build a simple rf receiver module that works at 27 mhz and turns on an LED anytime the signal from the transmitter is detected. A very simple idea, but as you will soon find out, a lot goes into making it a reality. We’ll be making our own PCB for this circuit, so get out the ferric chloride and copper clad PC board.”

“Project SlyBot is my venture into the world of robotics. I’m interested in the challenges involved in developing software systems to control movement and behaviour; so what better way to put them to the test than to build a robot! (also an excuse to play with Lego again 😉 ”

“I miss my old Commodore Pet. It was a blue-face with the chiclet-style keyboard. So, I’m recreating it in a Xilinx Spartan-6 FPGA. I’m using a Digilent Nexys3 development board. The design runs original version 1 or 2 ROMs.”
