Answering my own question, in case it helps someone in the future searching for this. The openarena package in Raspbian doesn't actually work on Raspbian. It's simply the version in Debian recompiled, and as such it needs desktop OpenGL rather than OpenGL ES, which is what's available on the Raspber...

Has anyone managed to get OpenArena to work on a Raspberry Pi 2 with jessie (debian 8)? This is what I've tried so far: * Setting the resolution in the config file to the same as the actual screen resolution * Trying a custom resolution * Forcing window mode. An excerpt of the crash log from openare...

This is being driven by a Raspberry Pi :-) http://photo.alioth.net/Random/nixie.jpg (larger picture here: http://photo.alioth.net/Random/nixie.jpg ) OK, so what are they? Nixie tubes are a (loooong obsolete, in the west obsolete by the 1970s, a bit more on that later) which were used for numeric dis...

I am a 12 year old computer geek, and I want a Raspberry Pi. I asked my mum, said I would use it well, pay for it by myself, ect., and she said no, I "don't need one." What can I do to convince her I should get it? Help! I'm probably going to regret saying this, but for things like this I live by t...

Now I've got my new RPi plus a monitor with HDMI in, I've been able to play around with RiscOS properly for the first time. It all works well...but the system doesn't seem to do quite full screen - there's a black border around the display. Are there any tweaks (perhaps to CONFIG.TXT in the boot par...

The DIY MOSFET shifter on that page has quite high values for the pull-up resistors - not a problem for slow moving signals, but when transistioning to logic 1 that 10k resistor has to at least overcome any parasitic capacitance on what it's connected to, which will make the signal rise time rather ...

Out of desperation, I've drilled a solder-filled hole (actually, I'm not certain it was solder) on a 4 layer board that wasn't a Raspberry Pi. I had tried solder wick but no amount of flux, new solder or solder wick would encourage the blockage to move. So I used a fine drill bit and *by hand* turne...

I have a project that I sometimes take to various shows (it's a multiplayer game for the Sinclair Spectrum equipped with ethernet, using a Raspberry Pi as the game server). The server is written in C and targeted currently at Unix. It's reasonably portable (with minimal #defines, it runs on Windows)...

The odd thing is that Wiki is obsessed about registers and doesn't bother tell you how many instructions are on the processor. That's because RISC is a bit of a misnomer: RISC doesn't mean "reduced" as in "few instructions" but "reduced" as in reduced complexity of the instructions (as opposed to C...

Just in case people are interested in seeing the RPi being a companion to 30 year old computers... :-) I'll be taking mine to Spectrum 30 in Cambridge (Sept 8/9 - see their website: http://www.spectrum30.org.uk/ ) once again to run as the server for Spectank, a multiuser networked game for Sinclair ...

With the help of the Raspberry Pi, the Sinclair ZX Spectrum bursts onto the world of e-sports :-) A project of mine is the Spectranet, an ethernet card for the old Sinclair Spectrum. Recently I received my Raspberry Pi, and with several retro meets coming up I thought I would combine it with a netwo...

Buenas Con la última edición de RetroEuskal (dentro de Euskal Encounter 20, hace un par de semanas) tuvimos una celebración de 30 años del Sinclair ZX Spectrum. Soy el autor del Spectranet, la tarjeta de la red para el Spectrum, y con la ayuda del Raspberry Pi por fin el Spectrum ha llegado al mundo...
