Heat shrink tube is a mechanically expanded  plastic tube, which shrinks when heated. The tubing is placed over the connection to be protected and then heated with an oven, hot air gun or similar tools. This processes causes the tube to contract and it hold tight the surface or wire. This is a very good protector of wire joints, but it can catch fire.

Heat shrink tube comes in different color and diameter. typical shrink ratio is 2:1 providing a snug fit over irregularly shaped joints. This provides good electrical insulation, protection from dust, solvents and other foreign materials, as well as strain relief. If overheated, heat shrink tubing can melt, scorch or catch fire like any other plastic.

Arduino Serial Board

This is my first Arduino serial board. made successfully working great. Auto reset is also working. Tested with Atmega8 chip.  When I made this board at home I have only Atmega8L-8PU, I searched the market but Atmega8A or Atmega8-16PU are not available. so I decided to go with Atmega8L and test this board with over clocking this AVR. Atmega8L supposed to run at 8MHz. running at double speed is not recommended. but it is working for LED…

Welcome

We have learn from our experience that when a person starts learning embedded system, he or she require some very necessary tools like programmers, development boards and micro-controllers. These things are still not available in many places of India. Lots of free and open source programmer and projects available on the web, but make them working is another challenge for students. So we make things simpler and offering you low cost solutions like Programmers, Development boards  for trusted 8051,…
