As I get more serious into my electronics hobby, I need to work with more SMD components. Some component packages are very difficult or impossible to solder with a traditional soldering iron. To solve this problem, I decided to hack a toaster oven to become a reflow soldering oven. Basically, to perform reflow soldering, solder […]

Instructables author extraordinaire Randofo created a great programming shield to use your Arduino to program 8 pin ATTINY processors. He was even generous enough to give 50 copies of it out to people who authored instructables using AVR processors. It works great on brand new ATTINYs and any chip that is programmed to use it’s Internal clock.

Update May 4 2012: I am still working very hard on version 3 of Picopter. The new version’s hardware is already done. There are new 3D printed motor holders. I’ve done some measurements with regards to mass and radio spectrum. I’ve posted stuff to http://www.frank-zhao.com/picopter_forum/index.php including the new design files, so take a look. Update Feb

LM35 can measure temperatures from -55deg to 150deg and we need negative supply voltage for measuring this negative temperature. This circuit eliminates the negative voltage power supply and this project can measure the negative temperature Download the protesu file to simulate the project on your desktop Bascom Code $regfile = “m16def.dat” $crystal = 1000000 Config

This project will display the temperature and time over the LCD display. LM35 is used to sense the temperature and the analog out of the LM35 is converted to digital by using the inbuilt ADC on the ATmega16 chip. An software clock is generated and the Time is also display. Download the Bascom code and
