I am currently working on:

I have:

a Zeo Personal Sleep Coach
a Suunto t3 heart rate monitor, with chest strap and watch
a Lego Mindstorms NXT 2.0 set and First LEGO League Challenge 2011 kit
a ZX81 (somewhere?) with 16k of RAM, and an HP-15C
an Arduino Uno R3 starter kit from Earthshine Electronics
a Kindle
a Raspberry Pi (at last!) and most components (still scrounging for an SD card)
a bunch of old mobile phones (including a SE K608i, a k800i, and a Nokia E90)
a pair of intact but dysfunctional Realistic TRC-201 GRS transceivers (walkie-talkies)
a 110 litre tropical fishtank
a Go board
a vintage Air Zound rechargeable signal horn
a Catwatch ultrasonic cat deterrent
a Sony CRX1600L (wired for North America)
an AlcoSense Elite digital breathalyser
an article in Adbusters
three children with Y2K-compliant incept dates (Do Not Hack)
one red paperclip (more precisely, I know someone who's willing to trade his)
a Sony DCR-TRV33E mini DV Digital Handycam whose video is shot (centre heads gone?), and probably some cassettes for it
3/4* round(Bachelor of Industrial Design) = 0

I know how to:

pick a two-pin lock
write in $L a T e X$ , most enjoyably Till Tantau's PGF/TikZ and Ulrike Fischer's chessboard and xskak

I would like to:

develop a tracking device that could fit in the front tube of my children's scooters in an attempt to detect the thief stealing scooters from their school
help my children engrave their names on their Haipad M7/Herotab C8/Dropad A8 tablets, and perhaps even repair the screen on one of them
hack my Zeo so that it can indicate how well rested I am, not just how well I'm sleeping (ideas here and here; project placer here)
hack my Kindle so that it can do whatever a Linux box should be able to do
code up the Black-Scholes option pricing formula in an esoteric programming language to add to Espen Haug's list
build a roving aquatic cam-bot for our aquarium (heros: Cambridge's coffee cam and Liquid Robotics' PacX Wave Gliders)
unlock my Desire HD so that I can use a foreign SIM card in it when travelling
find a good use for my www.wrongdoing.org domain
make an A3 e-paper device linked to Google Calendar for our kitchen
help start a Lego WeDo/Mindstorms club (would it be interesting to think about minimal hardware platform for their IDEs?)
convert a couple of PandoraBots into local RebeccaAIML entities
open source the Arkel's discontinued Samurai panniers

I have sourced Blinkybug components almost entirely from London shops:

5mm LEDs from Maplin
3V 2032 Li coin cell batteries from almost anywhere (Homebase was more expensive than the local Post Office)
guitar string (high E, custom guage 9) from Folkies Music
1.6mm OD copper tubing from 4D modelshop
pipe cleaners and craft glue dots from London Art
conductive tape from Farnell
