Re: Looking for 3D printing tips

Looks like it turned out really well! This was from 3D Print Direct, right? Looks like they do a good job and it's great that you could get such a large part in good-quality material relatively cheaply.

Overview of 3D printable cases and parts

Is there an list/archive of models for 3D printing for our Acorn computes and accessories anywhere? I have not found one so maybe it would be useful to have a pinned thread here where people can share models of common interest? Or maybe a new section to master new hardware list? I have found/used th...

Re: Looking for 3D printing tips

Regarding Shapeways and your earlier question then you get a "printability" response when you upload a model. As far as I know then they generate the supports needed as those needs can differ depending on the material.

Re: Looking for 3D printing tips

You will probably need to convert it to STL and check that it is properly "solid". There are multiple 3D printing services in the UK (just google 3d printing service uk) so you might be able to find one that can do it at a reasonable price. The larger things get then more expensive they are, and the...

Hybrid Music System Keystrip

The original keystrip for the Hybrid Music System is rather primitive so I have recreated it in the Acorn keystrip style, which I find more attractive and easier to read.

Interesting. For a Pi-hosted solution then a good start would probably be to port ncurses/curses as that would make a lot of command-line tools and games easier to port.

Re: Doom?

Maybe the textures could be dithered when read by the pi (or just preprocess them so they are stored processed) in order to add more nuance?

mlouka, I'll look at those suggestions - do they use GXR extensions do you know?

There are probably some Master-only educational titles t...

In case others will find this useful, this is my little cheat sheet for the FX calls. Print it out at 100%, cut it to size, then leave it on top of your beeb for easy access.
