Comparison of JPEG decoders
Bits and pieces:
Gaming resources, for Unreal Tournament and it's successor UT2K4
Public domain music, all copyright-expired under UK law.
Test card images.
Algorithms and software:
Recursive Voronoi drawing, simpler than Fortune's algorithm.
dupdelete, a generally useful file hashing and deduplication utility.
ASFView, analyser for ASF/WMA/WMV files.
File-summary and transformation toolkit, utilities for teaching and studying compression.
Risahash, perceptual audio hash function.
Vectorscope utility for audio.
Voronoi approximation for image disocclusion.
x264 encode testing script, vary parameters and graph results.
Zipfilerecover, zip and office document recovery utility.
Pixeltweek, image impulse noise removal filter.
Parscavenger .par2 file recovery utility.
BLDD compression utility.
Password manager, hardware password management solution.
Bird modem, a utility for transmitting data over an audio channel in a manner twice as fast and more reliably than that used by minimodem.
Windows 10 optimiser script, a script which kills off much of the Windows 10 spyware and telemetry systems and some of the general bloat.
Minuimus, the file shrinker: Automates the use of a number of file optimisation tools. Just point it to your data, and watch it losslessly get smaller.
Tiny 'web apps':
Cardadd, a utility to add up many single-digit numbers very quickly. Useful when playing Munchkin or Braggart.
Iconifex, a program for quickly performing rotate-scale operations on faces to position them for making ID photos.
Genus Loci, an educational game.
Exam clocks, created for use by a school. Suitable for displaying a combined analog/digital clock on a projector with space to display all required exam information. Color-blind-safe and compatible with the examination rules for all common exam boards.
Wind turbine v2.
Battery discharge protection circuit.
Arduino PWM solar charge controller MkI, a crude charge controller.
Arduino PWM solar charge controller MkII, a complete redesign that is far superior in every way.
Open design for a solar power optimiser.
Ideal diode design notes.
Common-positive ideal diode circuit, the near-perfection of the above.
Alternator voltage regulator.
Ultra-low-voltage linear power supply and component tester.
Observations on stripboard corrosion protection.
The Slender Flower, lightweight 2m/70cm dual-band antenna.
