Readers of a certain age may remember the SMART Response XE, a handheld computer released for educational purposes in around 2009 but since discontinued. Currently available very cheaply as a result (we’ve seen the opportunity to buy a box of 32 units for less than $300) they are becoming good targets for experimental hacks. Ingenious hacker chmod775 has turned an XE into a fully functional Linux terminal computer, as highlighted by Hackaday.
Pupils answered the questions on their terminals, and received immediate feedback as to whether they were right or wrong, while the teacher got all sorts of stats about pupil performance.
Experimenter chmod775 has turned an XE into a fully functional Linux computer, albeit command line only, by loading a terminal emulator onto the ATmega128RFA1 and hiding a NanoPi Neo Air in the battery bay where four AAA cells once sat. This causes something of a power deficit, which is fixed by adding a USB power supply.
Chmod775’s pictures show the NanoPi Neo Air running Ubuntu 16.04 without breaking a sweat on its Allwinner H3, a quad-core Cortex-A7 SOC with 512MB of RAM. The Raspberry Pi alternative’s square form factor makes it a good fit for the battery bay, and chmod775 says he’s using the machine for JavaScript, C, and Python programming on the move.
