f you’re a PCB electronics designer, you know how important it is to review your designs thoroughly before sending them to manufacturing. It’s costly – and embarrassing – to find design errors in a production board. You also know how difficult it is to really check everything in CAD. You’re dealing with multiple layers, so […]

Wireless Infrared UART prototype can be built by using two PIC16F876A controllers. One as IR receiver with dedicated Infrared decoder like SFH505A, SFH506 or similar IR receiver IC and other microcontroller as a transmitter via IR LEDs. This is relatively simple design and doesn’t require advance electronics knowledge or programming skills, especially if you are going […]

Introduction I have always been fascinated by photographs about lightnings. While it is relatively easily to put a lightning strike in any photograph using image editing techniques 🙂 I still prefer the real thing. Since photography is a hobby of mine, I wanted to be able to photograph lightnings. However, when I tried to do […]

STMicroelectronics Widens Access to High-Performance STM32 Microcontroller Line with New Devices in Small Memory Sizes The latest STM32F446 microcontrollers from STMicroelectronics introduce new choices for designers by combining enhanced ARM® Cortex®-M4 processing performance, compact 256Kbyte or 512KByte on-chip Flash options all with 128Kbyte RAM, efficient memory-extension interfaces, and extended connectivity and communication capabilities. Leveraging ST’s […]

It seems the cat protector project documentation has a small gap. There is just a hint that you have to use some scripts to prepare the SD card to play the audio files, but no details about this. To use the scripts you need some knowledge how to use a command line interface on your […]

This is a simple PIC microcontroller based Solar Tracking system, only basic electronics skills are required. It uses 2 unipolar stepper motors and 4 IR-850nm LEDs as sensors to follow the sun  maximizing solar panel illumination. The entire prototype frame was built from simple, cheap and widely available strip board. Just cut it to a […]

You can use this Universal Infrared Receiver (UIR) project to control your PC:  Starting Windows programs,  setting the Windows volume control,  even moving the mouse around the screen! All at the touch of a button – with your TV remote control in fact! It uses a PIC microcontroller to characterize the demodulated infrared signal and then […]

This project of mine started because I wanted to learn how to layout my own printed circuit board (PCB). I needed a simple and easy-to-solder circuit, so I chose this one because who doesn’t love interactive LEDs? In this Instructable I will only be showing the implementation of my circuit on a breadboard. In my […]

The new Martin Light Jockey II Lighting Software Kit is a new way to control your. LightJockey Manager is a free-of-charge software add-on for our LightJockey Page 2 the interface. In control panel, the USB interface is recognized as USB. A: I did test the Martin LightJockey, but this software doesnt support the interface. Free […]

I’ve always wanted to play with these 10W RGB LEDs! The Idea So for some reason I bought 2 IKEA lamps at a flea market. As IKEA furniture has a long history of being hacker-friendly, I figured they shouldn’t be an exception to the rule. My plan? Fit a few 10W RGB LEDs in there […]
