I’ve been working on a redesign of the original reflow controller. Here are the features for the new board:

Four MAX31855 Type-K Thermocouple interfaces
DS3234 Real Time Clock with battery backup
FT231x USB
XBee or Bluetooth Wireless
MCP23008 I/O Expanders for 2-wire expanded communication
ULN2803 Darlington buffered output relay/SSR control
Internal or external micro SD interface
External LCD I2C interface/input
ATMega 1284P TQFP AVR with Arduino bootloader
16 MHz Crystal

Take a look at the new board:

I’ll post more on this project in the coming days. I’ll be offering this project as a full kit for those who are interested.

Gallery – Hobbyduino XBee Plug V1.0

I’m pretty sure the majority of my projects will never be considered “Complete” as I’m always tinkering with the firmware to add or refine features. However, I like to give my projects a finished look which means they will be inside of enclosures or integrated into other devices. It would be nice if I could update the firmware without having to dissect the project to get at the controller. To accomplish this, I created a XBee plug for my Hobbyduino Mini V3 Arduino clone. Check out the gallery here and the tutorial here.

Tutorial – Wireless Arduino Programming

This tutorial demonstrates uploading sketches to an Arduino over a wireless connection. I designed a couple of XBee adapter boards for my Hobbyduino V3 (Arduino clone). These adapters made it easy to properly configure each of the XBee Series 1 modems used in the tutorial. Check out the tutorial for full details.
