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.

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 Proto Plug V2.0

I developed the prototype plug to further extend the mounting options for the Hobbyduino. A breadboard can be mounted for prototyping or components can be soldered onto the board. Go here to see it.

Project – Hobbyduino Mini Screw Plug V1.0

I wanted to expand the mounting options for the Hobbyduino Mini so, I created a screw terminal shield. This shield breaks out the Arduino pins to screw terminals and allows for easy attachment of wires. Go here for the project.

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.
