My name is Abraham Stolk, I am an indie game-developer from Vancouver, Canada, who turned electronics-maker.

My latest product is the Desk-side Stock Ticker.

It is a tiled-panel of 4 OLED displays that are used to scroll stock quotes on.

By default, it will scroll the stock quotes from the DOW-30 Index. But you can configure the symbols to use, over wifi.

The stock quotes are downloaded from the Internet, with a 3 minute refresh.

To connect it to your WiFi network, you use the WPS button of your home router. It was really easy to get going, thanks to the WPS example in the Arduino IDE.

I programmed it in C, using Arduino IDE.

It runs on either Stamp-C3 or Stamp-C3U.

I love the white-look of the Stamp-C3U: it is the best looking μcontroller in existence, I think. Although the black Stamp-C3 is a little easier to program, as you do not have to force it in bootloader mode the first time you use it.

Overall, I am a big fan of your μcontroller boards.

The production process was prototyping on a breadboard to validate the design. Once it worked, I designed a PCB in EasyEDA, and had JLCPCB manufacture the PCBs. Assembly was done in my home-lab.

I am particularly proud of how I managed to take cheap 1.3" OLEDs and tile them into a 140mm aggregate screen. Thanks to the fast SPI interfacing, I get high FPS out of it.
