AMX has written a command line tool to modify device files that are used by the pk2cmd tool: This gives a new device file named “pk2dev.dat”. I was able to dump and recompile the PK2DeviceFile.dat I am using and checked … Read more
When Ivan changed his TV provider they required the use of a SetTopBox(STB) as a receiver. Since it had HDMI output, he decided to use an old Philips 230C1 monitor as a TV screen. The monitor, however, was not controlled … Read more
Raj I recently designed this tiny breakout board for Microchip’s 24LC512 EEPROM and MCP9802 temperature sensor devices, both of which support I2C protocol. This single board can be used for both sensing the ambient temperature and storing it. You can … Read more
Chris from PyroElectro sent in this link to his project post for a device which generates some chirping and buzz-like noises every few minutes in order to slowly drive people nearby insane. The circuit consists of a PIC 10F202 MCU, … Read more
Room thermostat with PIC16F74, DS1820, and the Siemens M55 color LCD: The heart of the unit is an 8 bit PIC16F74 microcontroller from Microchip. It’s main task is to constantly monitor the room temperature trough a 1–wire digital thermometer IC, … Read more
Embedded Lab designed a mini breakout board for 18-pin PIC16F series microcontroller: This mini breakout board is designed to simplify prototyping and experimentation work with the popular 18-pin PIC16F series microcontrollers. It is small in size (1.95″ X 0.75″) and … Read more
Have a race car that needs a monostable multivibrator (one shot pulse) to control the pneumatic gear change actuators? Use a 555 timer, you say? Unfortunately, due to vibrations accompanying race cars a 555 controlled through a potentiometer is out … Read more
Bored of always typing in the same password over and over again? Luca designed a board to tackle just that problem. It’s a USB composite device, featuring both a USB keyboard emulator and a serial port. You program the letter … Read more
Chris from PyroElectro writes informing us of his project to achieve Motor Control via Proximity Sensing. He describes, “In this article, we go step-by-step through the process of understanding, designing and building a system that uses an infrared proximity sensor … Read more
Bertho is working on an {Avr|Pic} Stamp development board for his local hackerspace. These USB interface boards are based on the ATmega32A and PIC18F46K22 microcontrollers. Both boards use the MCP2200 USB-to-Serial IC to interact with computers over a USB virtual … Read more
Raj designed an open hardware DIY indoor thermometer and moisture meter. It’s based on the PIC16F688 coupled with the DH11 temperature and humidity sensor. The 7-segment display has auto brightness correction depending on the lighting conditions. This project is about … Read more
WebWarrior shows us how to program a PIC Microcontroller without a programmer: Here we specifically target the freely available ds30 bootloader for PIC microcontroller and show you how to program your device without the need of an external programmer. The video below … Read more
Ray reports he’s just finished working on a new open source wearable electronics controller board called SquareWear. It’s small (1.6″x1.6″) and has built-in USB port (used for programming the microcontroller, USB serial communication, and charging battery). It also has 4 … Read more
Dmitry Grinberg wanted to design a way to program MCUs that would be easy for beginners who don’t necessarily understand details of C such as pointers and memory management, yet don’t want to rely on common alternatives such as Arduino … Read more
FUN BitPack is designed for developing games on Orbit16 PIC24 and PIC32 development boards. It has a Nokia 3310 display, a Joystick, two buttons, and a buzzer: FUN BitPack is suitable for making hand-held videogames such as our “ORbitSnake”, a … Read more
Microchip has announced the release of a new line of USB 8-bit PICs. The new devices range from 14 to 100 pins with up to 128 KB of Flash. According to the announcement, sampling should begin in early October. All … Read more
Microchip and Digilent are having a chipKIT design contest. The contest revolves around the chipKIT PIC32-based Arduino compatible platform. The contest has 3 different categories. One is for applications using available shields and libraries. Another is for custom library development, … Read more
