Re: Testing procedure for newly assembled Gertboard?

I've completed my Gertboard and tested it with the programs in the user manual. As a newcomer to Linux it took me some while to work out how to run the programs, a process which is not clearly explained in the otherwise excellent user manual. Firstly, the programs are now provided as a .zip file, no...

Re: Power Through USB Hub

<t>As has been discussed before, this is possible.  The limitation might be that each USB outlet on the hub can only supply 500mA.  I'm going to use a 2A 7-port powered hub with a split (2xUSB-A to 1xMini-USB) cable which came with an external USB 2.5" drive, combined with a Mini-USB to Micro-USB ad...

Re: RISC OS on Raspberry Pi

<t>One of the key features of the Pi is the ability to swap the OS by inserting a different SD card.  I support the idea of a 'standard distribution,' which should be one of the Linux variants.  However a major objective for the Pi is to encourage people to program and experiment, which can be done ...

Re: Sourcing DC power cables

Micro USB is, supposedly, the new 'standard' for mobiles phones - certainly my last two Samsungs have them (so two PSUs there...) as did the Blackberry I used to have at work.

If you have a suitable mini USB PSU eBuyer (and others, I'm sure) do an adaptor from mini to micro USB.

Alternatively you could unsolder the sockets and replace them with trailing leads where needed. You'd need a desoldering pump or braid to avoid overheating and things getting stuck.
