Arduino

Some time ago I have decided to make myself a electric bike — e-bike as they are called now. However, buying a stock solution, I mean a stock e-bike, was not an option because mainly of two reasons. The stock e-bikes are quite expensive stuff, this is one. The second one is about the actual parameters of the electrical bicycle. Manufactures sell e-bikes which have limited power output to 250 Watts and are only meant to support you and not drive themselves. But wait a minute … This should be about a spot welder not the e-bike ;). Well, each electric devices ought to have a power source and this is how the idea about making my own spot welder was born.

For quite some time I was experiencing a problem with my router. When the temperature rises behind the window it just starts to freak out. Every once two weeks or so it drops the Internet connection. Local network is still running but the incoming or outcoming connections are terminated. The only solution to this problem is to reset the router or just take out the plug and insert it after a few seconds. However, it requires me to do this every few days to make sure that the connection is good and running. I have decided to automatize the process with Arduino since it was laying around.

Wireless transmission is getting more and more popular. I will try to show you how does it work using coupled receiver and transmitter which are both working on the same frequency (433MHz).

I have done a few project based on AVR microcontrollers. Recently, I have given myself a chance to try out Arduino. After my home thermometer broke down I decided to make a new one. Also it had a few drawback which required fixing. After some time I decided to use Arduino and design a shield for it which would enable this board to measure the temperature and display it. So here it is:

Simple Dual Thermometer
