The BEAM Links Collection is a BEAM Reference Library site.
BEAM Reference Library Links:
Disclaimer: I live in the US (Colorado, to be specific), so the following list of vendors will be pretty US-centric. It's not that I'm parochial, I just don't have much feedback from folks that live elsewhere. Consider yourself warned.
All Electronics -- Lots of odds and ends -- not a very complete selection, but worth a look for what they (temporarily) have in stock.
Digi-Key -- Huge supplier (US / Canada); they stock just about any electronic part you could want
Future Active -- Electronics components and tools
Jameco - Good prices on some things (particularly "grab bags"); oriented more toward service parts rather than chips & such.
Mouser -- Another big supplier; very pokey website
Solarbotics -- The best all-around BEAM supplier there is. They have lots of components at good prices, but they're located in Canada, so US buyers have to (for the time being) deal with the US Customs Dept. "aging bins"
Conrad Electronics -- Good prices but only ships in Europe
Jameco -- misc. solar cells
Plastecs -- solar cells, including flexible ones!
Scientifics -- what's left of the former Edmund Scientific; good selection of solar cells
Solarbotics -- a really good source for BEAM-sized (i.e., small) solar cells
SolarElectric -- primarily oriented toward folks that want to live "off the grid," they still sell individual cells too
Motors and gears and such
Balsa Products -- good prices on servos.
BG Micro -- the good news: they carry really great, affordable gear motors; the bad news: they hardly ever have them in stock
Budget Robotics -- Tamiya gearmotors
Jameco -- Various sets of gears (but they're not too cheap)
Micro Precision Systems -- really incredibly tiny motors
Mondo-tronics Inc. -- anything and everything involving "muscle wire" (a.k.a., Nitinol)
Servo City -- very good servo prices
Solarbotics -- very low-current pager motors
Tower Hobbies -- good selection of servos, replacement gear sets
Major Hobby -- broad selection of servos, gears, etc.
Misc. robotics parts, kits, and such
Acroname -- they carry really neat Sharp IR proximity sensors, plus other assorted goodies (books, PIC boards, even piezoelectric gyros if you're feeling rich).
Bawtz.com -- Canada-based reseller of other folks' robot kits
Budget Robotics -- they sell a number of basic robot kits (just add "brains"), plus a decent variety of 'bot parts (wheels, gear trains, motor bases, sensors, etc.). Most parts (and some kits) are straight from Tamiya -- at very competitive prices.
Carl's Electronics, Inc. (Electronickits.com) -- MOVIT and OWI robot kits; good basis for further "robohacking"
Cybug Central -- Craig Maynard's site on his interesting little bugs; available in kit form.
Didel -- a Swiss company with some really, incredibly, small robot kits and parts (sad to say, many of them are not cheap). Site in English and French.
Electric Pets -- Bill Bigge's line of really artistic and interesting BEAM "critters"
Electronics Goldmine -- they live up to their name, they have all sorts of goodies (tho' not always well-described)
Fastener-Express.com -- a good on-line fastener store, good selection of metric stuff too.
FirstBOT Robot Store -- primarily geared toward selling (processor-driven) robot kits, they also sell a few components separately.
GlobalSpec -- if you need some oddball thing, and have absolutely no idea where to find it...
Hobbytron -- a hobby supplier with a very broad selection of robot kits -- Solarbotics, MOVIT / OWI, Cybug, Mindstorms...
HVW Technologies -- a few kits, mostly CPU-based (but all hackable)
Jameco -- section dedicated to robotics
Lynxmotion -- they have some pretty pricey robot kits, but some very interesting (and affordable) robot parts
Micro Fasteners, Inc. -- dedicated to selling small nuts and screws and such. If you live in the U.S., and need / want to buy metric fasteners, this is definitely the place to go.
Middlesex University Teaching Resources -- teaching materials vendor, lots of goodies useable by BEAMers -- gears, gearmotors, electronic components, building material... Based in the UK, but ships all over.
Mondo-tronics Inc. -- has lots of odds & ends
MPJA -- a surplus house, often have good motors, tools, etc.
Andy Pang -- just an average guy, but he's got robot parts and part kits for sale.
Robotikits Direct -- OWI kit robots; good basis for further "robohacking"
Robot Store -- kits, books and various parts
Robot Store (HK) -- a Hong Kong based outfit that ships world-wide; motors, solar cells, sensors, CPU-based goodies
Rogue Robotics -- makers of the "Rogue Blue" series of robots
Scientifics -- what's left of the former Edmund Scientific
Solarbotics -- just about everything you could want for a BEAM bot, including kits
Vikon Technologies -- lots of CPU-based stuff
Jaycar Electronics -- they're in Australia, so I have zero experience with them
Oatley Electronics -- Ditto
Supplies & tools
Micro-Mark -- they bill themselves as "The Small Tool Specialists", and they live up to it! They're really oriented toward modelers (model railroad, model ships, etc.), but have lots of tools useful for detail work on small things (like BEAMbots!).
Ramsey Electronics -- tools, kits, etc.
Fred Martin also came up with the Mini Board, a tiny, business card-sized robot controller, great for connecting motors and sensors to desktop machines. The design is distributed publicly and you can buy blank boards from Douglas Electronics. More information on parts for the boards and schematics is in Fred's paper at MIT Mini Board Info; complete documentation is on the MIT FTP server.
