WyoLum is so proud to team up with Seeed Studio<\/a> and Repaper<\/a> to present the Open Hardware Summit<\/a>\u00a0badges (codename: BADGEr) for 2013! \u00a0We’ve had our heads buried working through a\u00a0myriad\u00a0of issues and recovering from a few big setback<\/a>s, but the work has paid off. \u00a0The prototypes are back and they are amazing. \u00a0We friggin’ did it! \u00a0Thanks to the grit and endless hours contributed by Anool and Kevin<\/a>\u00a0of WyoLum; Nana and Albert of\u00a0Seeed Studio<\/a>; plus\u00a0Sean and Charming of\u00a0repaper.org<\/a>\u00a0for helping out with software issues.<\/p>\nHere are the details.<\/p>\n
Features:<\/strong><\/p>\n\n- Repaper.org<\/a>‘s amazing electronic paper display\u00a0EPD (made by Pervasive Displays Inc.<\/a>). \u00a0A huge shout out to the generous support we have received from them. \u00a0We simply could not have offered this badge without them.<\/li>\n
- Arduino derivitive<\/strong><\/a>. \u00a0This is the new phrase for “Arduino compatible”. \u00a0The badge has an ATMEGA328 on board and can be programmed using the Arduino IDE by selecting the “Arduino Pro Mini 3v3 8MHz” from the Tools–> Board menu.<\/li>\n
- Arduino Shield. \u00a0<\/strong>Because the EPD takes up a lot of pins and a lot of memory, it makes sense to offload the business logic to another processor and let BADGEr handle the display functions.<\/li>\n
- uSD\u00a0<\/strong>slot. \u00a0You may have run up against the memory limitations of the ATMEGA328 already. \u00a0There is really no space left for a display buffer. \u00a0We use the SD card as both a display buffer to prepare new displays, as well as a disk drive to store images and fonts.<\/li>\n
- Buttons. \u00a0<\/strong>These buttons can be programmed to be whatever you want, but they are labeled MODE (left), UP, DOWN, SEL (right). \u00a0UP and RIGHT are connected to INT0 and INT1 so these buttons can wake BADGEr from power saving sleep mode. \u00a0The default program uses these buttons to navigate though a simple directory structure. \u00a0Folders are labeled A, B, C, … and each file is called A.WIF, B.WIF, C.WIF…<\/li>\n
- Power Options<\/strong>. 2450 coincell (~ 100 page turns), JST connector for lipo batteries, microUSB (5V), Barrel jack [not populated] (7-12V), Lanyard terminals (7-12V)<\/li>\n
- Interfaces<\/strong>. \u00a0Arduino Shield, FTDI, ISP, I2C. \u00a0Don’t like the software, got some better ideas? \u00a0Do something about it. \u00a0 Some things to remember:\n
