Throbbing Apple Logo Sticker This little gizmo adds the iconic “sleeping Mac throb” to an ordinary Apple logo decal. The idea for this came about when passing by the Apple Store in Palo Alto, California late one night. After hours, when the store is “asleep,” the lighted logos out front pulsate just like the power […]

Top 5 Wireless Ways to Communicate with your Controller
One of the strongest trend we have seen this year at CES2015 is, as you can imagine easily, the IoT (Internet of Things) development. Consequently, the most important component needed is the “connection and communication” module that enables the remote interaction between the device and “the community” via internet. Here we will sum up the […]
DCF77 clock-thermostat using PIC16F648A
Always at the right time your house on temperature This project make use of a PIC16F648(A) and a DCF77 receiver from Conrad (Orderno. 64 11 38) With DCF77 runs the clock from the thermostat always on the right time. Synchronizing isn’t necessary anymore. The temperaturesensor is a DS1820 or DS18B20 and on a HD44780 (or compatible) 2×16 LC-Display […]
Nike+iPod reverse engineering (protocol too) using pic microcontroller
UPDATE: code posted below Nike+iPod is a very interesting piece of hardware for all kinds of reasons, not the least of which is that it as actually useful. It works by wirelessly transmitting data from a sensor (that is stored in your shoe) to a receiver that is either externally connected to your iPod or […]
Misc Projects : High Power RGB LED Controller
This is an ongoing project to control a number (currently 5) of Lamina Atlas high power (350-500mA) LEDs. Current progress includes: PCB artwork (in Eagle) with connections for 5 RGB LEDs. Firmware for a Microchip PIC16f887 microcontroller to interface between the FTDI 245R USB chip and a number of Texas Instruments TLC5940 constant current LED […]
Ways you can use the DDS Daughtercard
How many ways can you use a self-contained, high-precision signal source contained on a 1″ x 2″ plug-in circuit card? How about as a stand-alone VFO, a signal generator for your bench, a replacement LO for your Sierra or NC40 transceiver, or perhaps as the heart of an antenna analyzer! Control it with your favorite […]
A Word Clock using PIC16F877 microcontroller
A Word Clock ************************************************************************** Major updates – A much better enclosure for this clock has been designed, and a better controller using an AtMega controller now exists. check out http://www.instructables.com/id/The-Wordclock-Grew-Up/ ************************************************************************** This is a project to tell the time using words. I saw a cool clock on the Make Blog the other day (http://blog.makezine.com/archive/2009/09/qlocktwo_clock_tells_time_with_word.html), and […]
DC motor control with Joystick and PIC16F877A
This is one project that i’m doing, now I’m going to show how to do it only for one motor, but i’m using and DEMUX to in the future use 4 motor. The project is simple, it uses the pic to control the DEMUX and the DEMUX control the H-BRIDGE that control the motor forward […]
Dialing Alarm using PIC16F628 Microcontroller
This is the lowest-cost dialing alarm on the market and shows what can be done with a PIC microcontroller. The complete circuit is shown below. You cannot see all the features of this project by looking at the circuit – most of them are contained in the program. So, read on and see what we have included. […]
