Projects – Hobbybotics Reflow Controller Quad V1.0

Here’s a quick update to the new reflow controller project I introduced earlier.  I have fully populated one of the prototype boards and began to write test sketches to ensure it functions properly.  The project is moving a little slower right now as I am in the process of closing on a new house and that has been taking up a lot of my time.

The last picture shows an early prototype for the LCD/Button interface for the controller.  I am in the process of redesigning the LCD/Button interface to use a 4-way rotary navigation switch with a center select button.  I borrowed this idea from the Viki LCD project over on Kick Starter.  I’ll post more updates in the coming weeks.

General – Arduino Optiboot Boot-loader

I’ll soon be updating the Hobbyduino Mini to the Optiboot boot-loader.  According to the Optiboot Google Code Page:

  • Allows larger sketches.
  • Is a quarter of the size of the default bootloader freeing 1.5k of extra space.
  • Sketches upload faster.
  • Optiboot operates at higher baud rates and has streamlined programming.
  • Adaboot performance improvements.
  • Runs sketches sooner with no watchdog issues.
  • Compatible with 168 and 328 Arduinos.

Project – Hobbyduino Mini Boot-loader ISP Shield

The Hobbyduino Mini allows for shields (or plugs as I call them) to be attached in somewhat the same way as the Arduino.  As such, I would like to present one of the first shields developed for the Hobbyduino Mini called the Hobbyduino Mini boot-loader ISP Plug.  This plug (or shield if you like) can be used to burn the Arduino boot-loader onto blank ATMega328 or ATMega168 chips.  In essence, this plug is a minimalist AVR ISP programmer.  Go here for the project.
