You can get external foldable keyboards for PDA pocket computersthat use serial I/O on ebay for about $5 to $10. I will post my results back to this forum when that happens. I will write whatever software I need WHEN I get around to that project (currently rather low priority). I bought some of these keyboards to use with my kindles. But hey, if you feel up to it, go for it. Unfortunately, this is an software and electronics hacking job. You also need software to configure you kindles serial port to use the same speed as your keyboard. You can build something fancier with transistors, or you can buy a ready-made level shifter IC or circuit. This can be done with two resistors and 3 diodes (or less). You could also connect an external power source (batteries or power supply).ĭepending on what model keyboard you have, it may be necessary to buy or build a level-shifter circuit to convert between different TTL voltage levels. You might be able to locate a source of battery power inside the kindle as well, but this requires some level of electronics expertise. There are kindle opening instructions for the different model in this forum and elsewhere as well. Other kindle models have the serial connector inside and require opening your kindle to access the serial port. Because the keyboard does not supply power, you can get power from the upper slot in the left side, but the bottom connector mus be adapted to short the bottom two pins in the lower slot to turn on battery power to the upper slot.
