I believe I have an improved design with the i2c solder bridges. Most i2c devices in the latest designs have a solder bridge to optionally enable the i2c pull up resistors. In addition, the address solder bridges are closer together to simplify soldering. Almost all sensor and output boards are now 2 layer, so that should lower costs in the long run. I have all the boards up on Tindie (other than some new ones we will be making projects for shortly). I am still testing the microcontrollers and finishing drivers. So those boards, though up on Tindie will be out of stock till I feel they are really ready.
I will be launching a tiny Indiegogo campaign to test interest in customizable flexible LED panels. The first up will be the 5" Light Square. We have some smaller rigid LED jewelry concepts that I will be experimenting with once the initial board run is delivered.
The mini EL works better than expected and I am very happy with its design.
