[tari] sent in a tip about a MAX5214 DAC evaluation board AVNET is giving away this summer.  The MAX5214 / MAX5216 is a neat little chip providing a 14 or 16 bit DAC with a serial interface in a tiny 8-pin package. [tari] thinks this eval board could be hacked into a function generator, and we’ve got to agree. Now, who wants to build one?

It’s entirely possible to take the MAX5214 chip and put it in a circuit with a small ARM uC, a display, and a few knobs, but that seems like a waste of time given function generators of this caliber are already available for about $60. It seems the most efficient hack of this dev board will be simply adding an amplifier to this board’s output and possibly programming a better interface than the current LabView software available.

If you want to tinker around with some free hardware and make something useful in the process, have a go at making a function generator out of this dev board. Be sure to send it in when you’re done.
