Lightpack: Prokachan and open

About 3 months have passed since habruchelovek @brunql published in this blog a description of the ambilight-backlight for a laptop. And today we are ready to present you with a completely redesigned, now banana ™ version of this open source device :



So, the project for these three months:

• Got a name
• He survived two revisions of iron and became modular (can be installed on any monitors / TVs / laptops with diagonals from 7 to 40 inches)
• Learned to work with a different number of LEDs from 1 to 8
• I learned how to fully use USB 2.0 thanks to the AT90USB microcontroller family (even the firmware can now be changed without a programmer )
• I got the opportunity to individually adjust the brightness of each channel for each LED (if suddenly there were LEDs with different heat of light in the party)
• Got rid of “childhood diseases” (flicker during data transfer, redundant settings, raw interface, etc.)
• Moved to GoogleCode project hosting
• Got even if not very typical, but still documentation

Unlike Pixelkit , we announce this project at an earlier stage and hope to get help, or at least advice from people who are really interested in it. Before you collect something on the basis of the instructions , wiring, and diagrams published by us , read carefully about the principles of operation of the device, if you have questions from the last time.
