PMGlobe; a programmable World
Globe that lets you see the world from afar, either from a fixed
viewpoint or turning with the sun (you can add your own places of
interest, measure distance, use macros, etc.).
Stereo imagery, including aerial and underground photography and
3D cave surveys. A few of my stereo photographs can be
found here. I’m currently experimenting
with a variety of viewing methods, of which the most successful so
far is a passive 3D monitor (mine is made by AOC).
Bicycling science (I have recently taken up regular cycling again,
after a 40-year gap); I currently ride a Charge Mixer with 11-speed
Tollos – a supervisor program
for ARM Cortex microcontrollers which I am developing as a base for
my experimental avionics and
low-power caving aids; you can run it on the mbed
and also many other devices, such as those from STM.
Technologies for use in caving with Speleogroup,
including high-power Light-Emitting Diodes (LEDs) and designing efficient circuits for driving them and testing them; also cave
surveying equipment and technologies (dead reckoning and surface
Lightweight (preferably solid-state) computers (one such is the
IBM Workpad, for which
I wrote Palm Globe; another is
the Acorn System 1 and the Emulator I wrote for that); I currently carry an Asus Eee PC 900
netbook (to which I added a fast SATA 32GB solid-state drive) and
(less often) a Lenovo Thinkpad X200s laptop. In 2012 & 2013 I have
been experimenting with Android devices (programming the Nexus 7
and various cellphones, and have switched my ’phone to an Android).
