Introduction Some time ago I started a project of reusing an old, crappy toaster oven as a reflow solder oven. I did some necessary improvements on the oven, like adding a glass wool isolation. I also examined dynamic characteristics of the oven by looking at its transient response to a step input power. Everything was … Continue reading PID Controller for a DIY Reflow Solder Oven
Introduction There is this USB specialized family or group of everyone’s favorite AVR microcontrollers. Apparently, you can use them as USB devices or hosts without any external components. Hell, you can even program them via USB port. All of that without any external component. One of those little guys I wanted to use for my last project (reflow … Continue reading Getting started with ATmega8u2 and other AVR USB microcontrollers
Introduction As the title suggests, my latest weekend project was a very exotic kind of robot: it was a vehicle based on the AVR Atmega microcontroller that can be controlled using voice recognition system of an Android phone. The project I made was simple, it only uses the basic functionality of the robot car: turn on, turn off, … Continue reading Arduino based, voice commanded, Android phone navigated, Bluetooth controlled – robot car
Introduction There are many, many, and many posts online about how to use Arduino board to program everyone’s favorite Atmel AVR family of the microcontrollers – Atmega. I haven’t made many microcontroller circuits from the scratch so I never had any real programmer, as for instance AVR ISP or USBtiny. But recently, I decided to make an Atmega168 … Continue reading Programming Atmega μC with Arduino – Troubleshooting
