PCB's have been ordered, should be here by April 13. Backers who did not need assembled boards should expect their boards+components to be mailed out by the end of that week (April 15). For backers who wanted assembled boards, add on about an extra week.
Make sure to check out the great site William has set up at http://beat707.com -- this site includes new videos and the start of some video tutorials to explain product usage.
Even though the Kickstarter period is over we're still accepting orders (see the http://beat707.com site, Purchases page). We're going to order about 5-6 extra sets of PCB's and parts for any stragglers so if you know anyone else who might want a Beat707, send 'em our way.
Also, if you want to upgrade your reward level we can accept the difference in payment through PayPal at <email@example.com>
The final board layout is shown in the attached image. We kept everything mostly the same in order to not require another prototyping cycle (that would have delayed things by about a month). We do have free pins brought out to header spots where you can wire in a CV gate output or potentiometer. Even more free pins are available on a header if you use a Mega.
A couple of small innovations to the final design are:
- Bottom of the board has been extended (dimensions are now 8.165" x 3.365") to allow numbering the buttons, and also provide extra mounting holes for stability. The board had a tendency to tip towards you when one of the 16 sequence buttons was pressed.
- LCD brightness and contrast potentiometers were replaced with larger through-hole devices that are easier to solder
- Great idea by William: PCB's will come with black soldermask, white lettering, key caps will be grey, except for red record button and red 1/5/9/13 sequence buttons (we attempted to show these button colors in the attached image).
- Extra mounting hole near top-right of board to allow LCD mounting hole to be used just for the LCD and not require a specially-sized screw.
Still coming up soon....
