I'd suggest linking to the github page https://github.com/Cushychicken/bfunc and/or call for users http://cushychicken.github.io/bfunc-call-for-users/ Personally as a product I'd be likely to buy it struggles without amplitude control

In I designed and built my own function generator

I'm working on building my own function generator! If you're not an EE - a function generator is a pretty common piece of electrical engineering lab equipment. I've got all the source files up on GitHub - feel free to take a look: https://github.com/cushychicken/bfunc I've also been keeping a weekly project journal. I just posted the latest installment today if you'd like to see what I've gotten up to: http://cushychicken.github.io/bfunc-weekseven-log/ I'm already planning a second prototype and board spin with more functionality. If you need or want a really bare-bones function generator for your home lab, get in touch! Instructions for how are in the post. )
