Wanted Features and Options / Re: Most asked for features so far
« Last post by specing on February 24, 2015, 10:26:45 AM »
All I/O connectors optically isolated and with software enables both on data lines and
on power lines. use cases:

  • charging USB devices without letting them enumerate
  • communicating with mobile phones without letting them charge (if laptop is low on battery or w/e)
  • providing 5V USB power to a protoboard without the chance to produce wierdness on data lines
  • administrator-enable for devices with DMA access (external/internal PCI-e)
  • controlled add/remove of PCI-e devices (hotplug?)

Perhaps an external wrist rest that has speakers built-in?

Are there any hardware level indicators, like there are seven-segment displays?
E.g. it has 8 LEDs built-in and you give it a 3-bit value? Possibly RGB? (see image)

I would suggest some cree warm white leds.. cheap and bright :)

color would be warm white.. because rgb only brings pain to configure :)
Can have ambient light regulation, but also allow manual change

RGB is not a pain to configure, especially if it is all controlled by open source and easily modifiable
firmware.

I use redshift that adjusts my screen's colours (appears more red at night and white at day) based on
time of day and I enjoy it. It would be great if everything else that emits light could also change
accordingly.

Wanted Features and Options / Crazy ideas

If LiFePo4 chemistry is chosen for the external battery pack (or some other with high discharge),
there should be a way to start your car with it in emergencies.

A 3-cell 100Wh LiFePo4 battery pack with 30C discharge (max) provides
100 / 3 cells / 3.6V nominal  * 30 times-discharge provides 277 amperes of
current or 3000 watts at 3*3.6 = 10.8 V

Problem: how to block current from coming from the lead-acid battery and/or the alternator from
 charging the battery (One does not simply charge li-ion)? High-power low-drop diodes?

The battery gas gauge is easy enough to do with the EC.

Map some key press or if the keyboard has the no longer used Access IBM key for example might be used for this.

Overall Design / Re: Why Modular?

Various x86 and arm cpu modules will be made available based on interest.

The battery, screen, hard disk, ram, and cpu (if socketed) will be easily replaced.
