Open Analog is about open source analog hardware. We take popular Integrated Circuits and turn them into transistor level PCB kits. This campaign is mainly to fund the second revision of our SevenFortyFun kit which you can check out at http://openanalog.brace.io 

 or at http://github.com/OpenAnalog/SevenFortyFun

or at http://upverter.com/OpenAnalog 

 The first Open Source analog IC kit from Open Analog has been created, assembled, and verified. We call it the SevenFortyFun and it is a transistor level op amp kit. You can finally get the chance to understand whats going on inside those ICs! Now we need your help to proto the next revision (I gotta eat somehow!). This Kickstarter campaign is to raise money in order to print the first batch of PCBs and order parts for production volume. Changes to the board include: 

            - Component outline changes

            - Trace rerouting

            - Holes for standoffs 

            - Make it pin compatible (number wise) with a 741 OpAmp

While this may not seem like significant changes the time and cost of this endeavor is too steep for me to conquer alone! With your help we will be able to bring SevenFortyFun Rev 2.0 to life!

In addition, your funding will also back the next kits in our product line! Kits on the drawing board include:

              - 555 Timer

              - Low Dropout Regulator

              - Switching Regulator

              - Suggest one! email open.analog@gmail.com

Risks and challenges

The risk is that Rev 2.0 does not work. Why would this happen? Simple mistakes in layout of the board and trace routing BUT this is easily avoidable. The board is open source and you can follow and help the project along on Upverter @ www.upverter.com/OpenAnalog, this will help eliminate mistakes and risk!
