Hi All

Chinese copy-cat Arduino boards run from $8 (R160) on Ebay.

Spoke to some programmer buddies of mine in the US, they reckon that is by far the best option you have. Use the Arduino open software to program the board then your own software to read and write date to the Arduino drivers.

Cpap blowers check out ALIEXPRESS.

Ebay DOES ship to SA, just takes a while.
