Here’s a SLENDUINO development board based on PIC12F683 by C/D: The idea of this project was born from the necessity of create projects focused to mobile; therefore PIC12F683-I/SN was almost immediately our first choice for the features of this microcontroller. Files available on Github.

Rapid development board for PIC12F series microcontrollers
Here’s Embedded Lab’s new development board for PIC12F series microcontrollers: The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice […]
A PIC16F145x based PIC16F145x USB programmer
From the comments on our PIC16F145X: Full-Speed USB with no external crystal post, Maurice Bos writes: I wrote software to turn a PIC16F145x into a PIC16F145x programmer (over USB). It’s free and open source (GPL3), and it might be useful. Add any feature requests (or bugs) on Github, or just e-mail me. :) Via the comments.
LMD18245 base Microstep motor driver
In this video Dilshan Jayakody demonstrates his open hardware project the LMD18245 micro-step stepper motor driver: This article describe the LMD18245 and PIC16F877A base 16 step bipolar stepper motor driver which is design to work with 12V 18º bipolar stepper motors. In this design we use pair of LMD18245 DMOS full bridge motor drivers to control 2 phases […]
Diolan firmware update tool for PIC18F2550 used in USB IR Toy
Dobrica writes, “I’m in the process of setting up my HTPC, so I ordered USB IR Toy to be able to turn TV on without using remote control.” Result it fw_update for PIC 18F2550 which IR Toy uses , updated wiki page about IR Toy firmware update on Linux and comment on bug tracker. Hopefully, this will […]
PIC32mx based drum machine running in jam mode
Matt posted an update on his drum machine with a new 32bit PIC and a new larger LCD we covered previously: My initial prototype was based on a fairly common PIC available in DIP format, the PIC24FJ64GA102 which has 64kb of flash and 8kb of RAM. As I started to build up the firmware I quickly found myself […]
PIC based wristwatch project
exapod shared his PIC based wirst watch project in the forum: i’m building a PIC based wrist watch with a sharp memory lcd as the screen. it has an accelerometer, 4 push button,rgb led for the backlight, a micro usb connector for charging the lipo and a an 18 bit adc for fuel gauge.The pic is […]
DIY PICKit-2 Lite
oakkar7 made this DIY PICKit-2 Lite : Since, the first use, I stick all with my PIC development and found that very stable and convenience to use. My design is based on Blueroom-electronics design. The Blueroon website is down now. This is the copy of PicKit-2 lite schematic from Blueroom. I used BC547 and BC557 transistors […]
LED display matrix using PIC16F1847 and shift registers
Here’s Embedded Lab’s new PIC project: Making a 8×40 LED matrix marquee using shift registers: This project is about constructing a mono-color LED matrix display board that consists 320 LEDs arranged in 8 rows and 40 columns. The heart of this project is PIC16F1847 microcontroller which receives data from a PC through a serial port […]
Superprobe meets vintage multimeter
Mountaindude writes: “Built myself a Super Probe, in part based on DP’s design, parts from the original design. Nice little project, all in all”: It’s really just a Superprobe in a somewhat unique (probably not, but I like the concept..) case. The Superprobe exists in various flavours, the ones I’ve liked best so far are […]
PK2DeviceFile.dat editing tool
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 that the files are identical using “diff”. There are probably still some bugs but I […]
STB Zombifier adds IR remote control to TV box and monitor
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 by the STB and had to be switched on and off manually (not via the […]
Tiny breakout board for 24LC512 EEPROM and MCP9802 temp sensor
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 view the circuit diagram and get more details on Raj’s Tindie project at EmbeddedLab. Via […]
The Annoy: a 10F202 based tiny intelligent buzzer
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, two caps, CR2032 battery and speaker. He built the project as a way to illustrate […]
PIC16F74 – room thermostat with colour LCD
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, a DS1820 from Maxim, and to switch a relay on or off, that controls the […]
Mini breakout board for 18-pin PIC16F series microcontrollers
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 is breadboard friendly.
PICShift programmable monostable multivibrator
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 of the question. A solution proposed by the Ohio State University’s formula team is to […]
Type4me USB keyboard emulator automates passwords
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 sequence for the keyboard to type via the serial port, then press a button on […]
IR proximity motor control
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 for input, correlates that input to how far away an object is from the sensor […]
{AVR|PIC} Stamp dev board is simple, fast, has lots of I/O and serial
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 COM port. There are often things you want to test quickly when designing something. Most […]
