Ask Slashdot: Good Books and Tools For a Software/Hardware Hobbyist? 85
postermmxvicom writes "I have a friend who is a mechanic, but enjoys tinkering with software and hardware as a hobby. I want to get him a gift that will either broaden his horizons or deepen his understanding in these fields. He is proficient at soldering components and removing them from circuit boards. His programming experience is with a wide variety of scripting languages. He recently used teensy and arduino boards and an accelerometer to add some bells and whistles to a toy car he made. He also used his knowledge to help a friend find and correct weaknesses in his shareware (that would have let 'customers' share more freely than intended). He is fascinated that people can create chips to modify existing hardware. Do you know of any good books or kits (or even tools of the trade) that would appeal to a hobbyist and allow him to grow? Is there anything that might also play off of his handyman/mechanic abilities?"

His law states that headlines ending in question marks can be answered "no", but, based on his statements and the obvious intent of what he meant, it would have been better stated as saying that a headline ending in a question mark is almost always properly answered as "no". The idea there is that if a journalist doesn't trust their sources and information enough to make an assertive headline, then the article is almost assuredly a sensationalist piece that has little basis in reality, and is thus best deal

Easy answer (Score:1)
Arduino is designed to be used by artists. The tutorials are amazing. So, anyone who wants to create something can just string together several tutorials and have a truly awesome project.
The other thing is that the Arduino is extensible. When you get tired of Arduino's programming language, you can write in C or assembler. If you want to create an inexpensive stand-alone project, the Arduino board becomes, effectively, a chip burner.

Important Note: The RPi Wiki takes pains to remind you that these GPIO pins are unbuffered and unprotected, so if you short something out, you could fry your whole Pi, so be careful! There are a number of other breakout boards being developed that should make this safer.
Like an AC posted earlier, the barrier to entry is significantly lower for Arduino simply due to the easy step-by-step tutorials available. In a year or two, I'm sure there will be many great tutorials for the Raspberry Pi and friends.

Amateur radio is good, IF he is someone who is really social. I'm not, and I found it quite boring after a while. I think people forget that aspect of it. The whole idea of ham radio is to talk to other people, and quite frankly, I don't WANT to talk to other people for a hobby. I want to build things, modify things, break and fix things, etc. I do think that there are many aspects of the hobby that ARE enjoyable, but unless I NEED to communicate with *other amateur radio operators* then its useless to me.

Re: "The whole idea of ham radio is to talk to other people"
Amateur radio does not at all have to be about communicating with other hams.
For example:
We use the amateur radio APRS technology to track weather balloons that we send up to 100,000 feet or so. I integrated all of the electronics and fabricated the balloon communications payload. I built all of my antennas. A friend projected the flight path and tracked the balloon in flight. We have flown 6 or so flights. It is a blast.

2) O-scope. Super handy and fun too. Old analog ones can be had for cheap. Check craigslist and ebay.
3) Logic analyzer/Bus Pirate. I realize these are two pretty different things, but they fill a similar place in the "debugging digital stuff" category.
Other than tools, I think some kind of audio kit/project would be cool. IMO nothing helps you learn more about how electronics really work than analog audio, synthesizers, amps, etc. It really helps connect the concepts of how voltage/current/power/etc are connected since it all ends up in a very tangible (audible) medium.
