For those that are already the au fait cognoscenti, which
is a good starter kit to go with for amateur radio dabbling? I'd be especially interested in lots of digital and analogue I/O My background is that I've always been happiest with naked machines so have not investigated the world of built-in OS and language before. |

I prefer the raspberry pi to arduino as it has IMO a lot more ready made projects. Arduino is good if you are happy with C and C++, the Pi gives you Java, python... in fact just about any language you can name. Arduino wins out on peripherals, the 'shields' provide a lot in connectivity with the real world. If you buy a pi then within a few minutes of taking it out of the box you can have a wspr beacon up and running (a bit longer if you want a nice clean sinusoidal signal). Great for testing your antenna and the propagation. Andy |

Andy =========== 1) The Arduino is a microcontroller circuit board with input and output pins ,but cannot be loaded with an Operating System . 2) The Raspberry Pi is a computer capable of being loaded with an Operating System . It also has a number of I/O pins. NB ; The Pi version 3 ,model B ,recently launched ,has an ARM quad processor 64 bit and 1 GB RAM .........a lot of computing power for GBP 30.- ,.....fantastic !

Given the OP's request, I would recommend a TI Launchpad (~$15) using an ARM Cortex-M4. They are good processors, much more capable than the AVRs on the Arduinos. Of course that is not the only issue. Likely more important than the details of the board or chip is the development environment. I've not Arduinoed myself, but my understanding is that line of MCU boards has a lot of software and there is no shortage of web based info and references. I don't use C or Python myself. I use Forth which is available for the Launchpads. I find it much more interactive and tuned to the needs of hardware oriented users. If you like the rPi, the 2 or 3 are good development platforms and the zero would be a great embedded board for only $5. I haven't been able to buy one yet. I don't want to pay $7 shipping for a $5 board and the local (to a friend, not me) store is always out of stock. Seems they aren't making a lot of them. I expect I'll have a 3 before I can get a zero. There is a group for the rPi, comp.sys.raspberry-pi -- Rick |

I have not used that since the 80s although I was quite impressed by the speed and being an HP calculator user RPN was quite familiar. I started using it on the ZX Spectrum and it was my first Non-basic high level language. It may be time to dig out a forth pakage and see what I can still remember. IIRC it was originally developed for radio telescopes so there is a nice radio link. Andy |

I think the radio telescope thing is long past. I don't recall there being any trace of telescope control or radio left in the language. -- Rick |

For maximum i/o pins, then the Arduino/Genuino (outside US name) Mega is the best. Upto 54 digital i/o pins and upto 16 analogue inputs. It's not the cheapest to get started with, but it all depends on what you want to do with it. Clones are available, but I've had some cheap ones from China which don't do all they should. Getting them from a UK source seems to be the best middle road option.
Although not as capable as a Pi, they work as soon as power is supplied and are much less power hungry. There are always alternatives to anything, but the arduino user base is huge as is the number of webpages devoted to them.. |
