Viewers of a specified age may well try to remember the Clever Response XE, a handheld laptop or computer unveiled for educational uses in all around 2009 but considering that discontinued. Now available pretty cheaply as a end result (we have noticed the possibility to get a box of 32 models for much less than $300) they are becoming fantastic targets for experimental hacks. Ingenious hacker chmod775 has turned an XE into a totally purposeful Linux terminal computer, as highlighted by Hackaday.
The concept of the Clever Response XE was that instructors could compile a examination or other assessment on a host Computer (a Pentium 4 was required, or an early Intel Mac) then distribute it to a fleet of XEs by means of IEEE 802.15.4 very low-energy wireless, the normal made use of these times in Zigbee and other house automation expectations. The XE almost certainly has more processing ability than a Hue lightbulb, but its ATmega128RFA1 microcontroller and wireless transceiver device is not just going to operate Crysis.
Pupils answered the queries on their terminals, and gained speedy suggestions as to whether or not they were being right or incorrect, even though the teacher received all types of stats about pupil efficiency.
Experimenter chmod775 has turned an XE into a totally useful Linux computer, albeit command line only, by loading a terminal emulator onto the ATmega128RFA1 and hiding a NanoPi Neo Air in the battery bay in which four AAA cells as soon as sat. This results in a little something of a electricity deficit, which is preset by incorporating a USB ability provide.
