Other "green" technology
Prototype Mark II
*The Solo case has a standard 75mm VESA mount and may optionally be held by a wall bracket or desk-top arm.
#Production units will offer an ARM 9 processor option
+USB port and PCMCIA not fitted on the Mk II prototype.
LCD screen size: 8.4" or 10.4" @ 800x600; 12.1", 13.3" or 14.1" @ 1024x768 (XGA). The smaller the LCD screen, the less power is required to run the Solo. A minimum of one 10w solar panel is required for screens up to 12.1" in full sunlight.
Input devices: Keyboard, mouse and touch-screen options are covered on the Input devices page.
Case material: wooden, with optional outer layer of Dibond aluminium composite (Alusuisse). Refer to the Design & Construction page. Other case materials on request.
Storage: internal; Compact Flash or IBM Microdrive up to 1Gb. external; Compact flash via optional PCMCIA interface.
Battery: internal 12v lead-acid 1.2Ah or 2Ah, or 2Ah NiMH (Nickel metal hydride)
Solar panel: Polycrystalline or amorphous silicon. The former are more efficient per m2 in full sunlight, but amorphous silicon
units are 'shadow tolerant' and can also be supplied in a flexible variant. Guide-price is £100 ($150) for 10w.
The choice of power sources is wide. Any AC or DC supply from 6 to 30v will be capable of driving a Solo. Any shortfall in the power required is made up from the internal or external batteries. Excess available power is stored back in the same batteries.
In the event of a complete power failure, and the user giving no response to on-screen warnings, a 'last resort' battery within the Solo itself will close all open files and shut down the computer cleanly.
