Gmu 0.9.0 released

2013-02-15 22:06
It's been a long time, but here I am, back with a new Gmu release.

Gmu with default theme with new nice large font

Gmu 0.9.0 comes with the lots of changes (and some bug fixes). Some of the most important ones are:
  • A much nicer large font (Pandora default and compo themes, pixeled by hand :)
  • Some additional characters in both large and small fonts (including the µ character due to popular request)
  • A new ncurses terminal text frontend for Gmu (usable over the network!)
  • Experimental WebSocket browser interface (also usable over the network)
  • Support for Joystick axis control in SDL frontend (to support devices like the Caanoo, that come with analog controls exposed as a joystick)
  • The current playmode is now always visible in playlist view in the SDL frontend
  • Gmu has been changed such that it uses UTF-8 encoding internally for all text
  • Support for building Gmu statically has been added (in addition to the default configuration where Gmu's frontends and decoders are build as runtime loadable plugins)

A simple power indicator LED mod or: Why are super-bright blue LEDs so common in consumer electronics?

2012-10-15 17:29
Since the wide availability of blue LEDs, manufacturers of electronics devices tend to use blue LEDs as power indicators. They especially seem to like those extra-bright blue LEDs.


I, on the contrary, find them pretty annoying. Am I alone here? Do people actually like them?

Arch Linux ARM image for Zipit Z2

2012-09-12 20:30
Quite some time ago, I have written a blog entry about how to install Arch Linux on the Zipit Z2, but I did not provide an image back then. Now I have prepared a ready-to-use image of Arch Linux ARM for the Z2.


It is based on official up-to-date packages. Only for the kernel I had to build one compatible with the Z2.

STM32F4-Discovery board review

2012-07-04 22:25
Recently, I have been asked by Farnell if I were interested in taking part in their free product road test program. As I like tinkering with electronics stuff, I said yes and chose the STM32F4-Discovery board as an item to test.


The STM32F4-Discovery board is little development/evaluation board from ST to promote their STM32F4 micro controller series. The STM32F407 on the Discovery board consists of a 32 bit Corex-M4F ARM processor (which can run at up to 168 MHz), 192 kB of RAM (112+16+64 kB), 1 MB of flash memory and lots of peripherals (timers, DMA controllers, DACs, ADCs, two USB OTG ports, ...) and of course lots of general purpose I/O pins.

Commodore 64 Power Supply Repair

2012-06-03 15:13
The repair I'm describing here involves mains voltage, which can be very dangerous if not handled properly. Do not even think about trying this yourself if you are not absolutely sure what you are doing!

C64 power supply

The original power supply of my C64 was broken. Unfortunately it was one of those power supplies where everything inside the case has been glued into one big block filling the entire case. Repairing such a mess seemed next to impossible.
