So I've been sick and not really in the mood for Making or Blogging the last couple weeks, but in the last 3 or 4 days Ive made some significant progress and wanted to report of our triumphs and failures so far.

Why a wearable voice recorder?, Well, why not is the short answer.

It was your typical evening and I saw this contest announced and thought "we'll if a trinket pro is just another arduino clone I'm sure Rue and I can whip something up.

I called Rue one night "so hack a day is running a new contest, Using an Arduino clone from ADAFRUIT, should be a no brainer right?, got any ideas?" Rue and I Bounced back and forth a few ideas before he came up with the voice memo recorder idea saying "you cant find, ANYWHERE, a voice recorder that does not create a new file every time you record something"

He went on to explain that for him and a bunch of guys he knows who do service tech work it would be great if they could record a long string of individual messages, over a day, into one file, which, you could later sit down and copy your days into a log book; think model numbers, times on and off site, loose ends from jobs.. that kind of thing.

seemed doable and with the abundance of open-sourced projects and examples should be doable in time for the deadline.

we decided we would need to integrate a (micro)SDcard for storage, giving the user the ability to simply remove the card and copy your memos to your pc, Or smartphone.

Perhaps we though the device may not even need to have playback ability, be nice but not required.

Geez it could be really small, like as small as a watch even. that's when we thought, well wearable tech is all the Rage, this thing could be wearable; people cant seem to get enough wearable tech, from "smart watches" that dont even really do anything or people pinning a rgb led in a shirt, people love it.

we both had a bunch of pro-minis so we decided we would prototype on them and order a Trinket for the final product, Rue also ordered the needed SD cards and adapters, some very small mp3 player batteries and a trinket pro.

After doing some research and thinking a lot about our goals our parts finally arrived and it was time to build a prototype, Always Seems simple until Murpy's law kicks in.

More Next Time.
