Get the CalcHack PCB, you may buy the components according to the parts list from Digikey and buy the bare PCB`s separately, or just buy a preassembled and preprogrammed board (I`m planning to do a kickstarter campaign.)In the first case you will need...
Solder magnet wire from the CalcHack PCB to specified points on the calculator`s internal PCB (there will be instructions on how to find the pads for each supported model)
Develop the schematic starting with the micro-controller.1. Place the selected micro-controller symbol into the schematic. It is suggested that the micro-controller symbol be a semi pictorial viewed from the top with the pin numbers placed at their physical...
There are many components within this project, each requiring a fair amount of build time. High level list of steps is below:-PreparationAcquire PartsProgrammingLoad appropriate firmware on to RFD900 modemsLoad latest code into Payload ArduinoLoad latest...
WHAT WE'RE BUILDINGWe're building prototypes for our http://www.protocolsquared.com project. This board is the hardware platform for a next level protocol analysis and generation tool. It has an ARM chip, ESD protection, logic level converters,...
PCB INSPECTIONInspect those bad boys. Sometimes the PCB manufacturer will screwup the silkscreen or solder mask. Their quality control should catch it, but it's always good to double check and start with a known good panel.
QUICK PRODUCTION RUN THROUGHThe board will be going through two reflows. One for each side of the board.This means the first side will be heat stressed by going through reflow twice, this is the side where temperature insensitive components should be...
