It really took me 10 years to build that programmer !! Don’t be surprised , I actually started building the original programming circuit of Microchip PIC 16F84 ( JDM 2 ) on 2003 and finished it in 2 days. Then  on 2013 , I found that it can be reused to program the advanced Microcontroller […]

Only 0.5 mm thick (or thin) SMD LED Kungbright KPHCM-2012 can be placed practically everywhere, without increasing an overall PCB thickness. LED production technology currently surprises mainly on the field of white LEDs for lighting (SSL). But also color LEDs are getting still better as for the efficiency or for example in case of series […]

It’s holiday season and the chances are some of your gadgets will be also be going along for the ride. The ThinkPower mobile charger by Zettaly has been designed to provide essential recharge capability for USB-charged devices when you find yourself any distance from a mains wall outlet. The ThinkPower itself can be fully charged […]

Version 2 of the desktop Othermill milling machine is now available, and it’s accurate enough for a range of machining tasks, including double-sided PCBs. The machine can handle a range of materials, like brass, aluminum, wood, and plastic. For PCBs, FR-1 is recommended over FR-4. With a small milling bit, footprints as fine as TSSOP […]

These are simple modules I made with a pic 12c508 microcontroller. I use them to create different effects. The Mosfets are capable of some decent curernt with very little heating. I have used these for sequential turn signals, flashing brake lights, alternating flashers, strobe effects for leds, fade in out for a dome light etc […]

  Usea C-52 EVB for simple robot experiments. Build a simple two wheels robotwith L293D H-Bridge driver and IR sensors. Write a C program controls robottracked with black tape. Fun with Ving-Peaw Competition 2543, course layout,day-by-day changed rule and scoring also included! Introduction One of my student has made a disgracefulrobot that used two stepper […]

OVERVIEW ARM PRO MINI is a small barebone open source ARM M0 microcontroller board that is great for quick prototyping and as a starting point for your own ARM based custom designs. It was designed and named after the venerable Arduino Pro Mini and it is an excellent stepping stone for makers and hobbyists ‘graduating’ […]

LED matrix displays provide flexibility to display text, graphics, animations, and video, and therefore, they have become a popular mean of displaying information these days. You can see them at gas stations displaying the gas prices, or in the public places displaying information, and alongside highways displaying advertisements on large dot matrix panels. This project […]

USB interfacing for AVR microcontrollers Since the release of V-USB, dozens of projects have been made that allow an AVR to communicate over USB.  USB data signals are supposed to be in the range of 2.8 to 3.6V, so there are two recommended ways to have an AVR output the correct voltage.  One is to […]

Design Goal:   The JavaBot1 is a small line following robot designed to follow a black line drawn on a dry erase board. It is designed to follow very tight curves. The software still has lot’s of room for improvement but works well as is. Motive Power: The JavaBot1 uses 2 Cirrus CS-70 servos that […]
