Samtec do a range of pre-made cables. Check out their range and if you find anything suitable let me know and I may be able to get one for you.

Would something like this do?

What's that sound effect?

* Caution - may contain Grotbags and Emus * There's a sound effect common in 80s kids' shows, commonly used for anything from bubbling cauldrons to unorthodox machinery. It's here quietly in the background. A kind of semi-tuneful blarping and blooping. https://youtu.be/n9jmNVPHirQ?t=222 Does anyone ...

Re: What are people happy soldering ?

I use Hakko T18-C3 . The idea that you need a tiny tip for fine work is nonsense. A tiny tip won't deliver the heat you need. It's all about the flux. Also like Daniel said don't use huge amounts of solder. In the video below I'm just using a tips worth. If you connect 2 pins then just either drag ...

Re: Request for help in organising/releasing source code

+1 to that. Baby steps. Commit in what you have, as it is, and learn about how the system works. Especially branching. Branches don't cost anything and are perfect for experimenting. Keep master clean/working at all times. Work in a branch until it's looking how you want it to then merge that back t...

Re: new to atom: ram rom mmc joystick

I have to admit that I didn't consider mounting on top like the econet board - I always just imagined popping the main interface board underneath the atom motherboard with the slot card hanging outside. I didn't think there was room on top as it's pretty cosy there under the lid. I was wary of short...

Re: Master spray job

I use vinyl dye to colour plastics. It apparently bonds with the plastic rather than covering it, so it doesn't chip or peel. It also doesn't affect the texture of the surface you're painting as much as a regular paint. The colour range is slightly limited though, and it's more expensive. Still wort...
