Components

Supplier	Free Shipping?	Notes
Bitsbox	No - £1.50 Regardless of order size though.	They have every component you could want, normally always in stock, at a cheap price, with good delivery times.
Futurlec	No	Good supplier, very cheap SMD to DIP converter's which are useful for prototyping.
RS Components	No	Not always the cheapest, but you can collect from a trade counter.
Farnell	Yes	Larger selection than RS and free shipping, however there is a minimum order to qualify.
Digikey	Yes	Even larger selection than Farnell and free shipping on orders over £50.
eBay	Varies	Always a good place to start, direct access to Chinese sellers without the risk.
CPC	Varies	CPC is a sister company to Farnell. They supply a smaller range, but sometimes cheaper.
Rapid	Varies	Rapid is a sister company to RS. They supply a smaller range but sometimes cheaper. Generally they are my first place to look for a component. Not a very good selection of ICs.
Mindsets (formerly Middlesex Uni Teaching Resources)	Varies	Mainly supply items for education. Always a range of fun and interesting devices, components and equipment. Prices generally good.

PCB suppliers and manufacturers

Here is a list of PCB suppliers and manufacturers which might be useful to doing small scale batch runs of PCBs. If you know of any then please feel to add or review them.

• PCB pool/Beta Layout

These guys created our Nottinghack learn-to-solder badge PCB and are generally great.

• Olimex

I've not used them. Cost £24 for 100x160mm

• Stickleback Manufacturing

They sell 1sq ft PCB double sided on eBay for £60 inc P&P. £70 inc P&P.
Matt Little "I've used them twice and they were good quality board at a great price. Quite long time to deliver."

• Spirit circuits

Not sure how expensive. They have an amazing 'Go Naked' service where you get a double sided etched board (no solder mask or silk screen) for FREE. This is to try out your idea. If you ask for too many of these (more than 3) they wont do any more until you place an order.
Matt Little "I've used the go naked service and was amazed - fast and useful. The board has a load of advertising on it though and is not cut out to your PCB size."

• Elektor PCB prototyping service

Matt Little "I've used them once and they were good - fast delivery, decent board. Relatively high cost, but OK for prototype run"

• iStore prototyping service

Via KiCad users group, a UK member uses these guys.

• CapnKernel direct

This Austaralian guy lives in China. Hes started a PCB service, but only direct by chatting with him and only using KiCad as CAD package. He says to chat with him on KiCad IRC channel: Name: CapnKernel at http://webchat.freenode.net/?channels=kicad

• BatchPCB

A PCB service based at Sparkfun in Colorado (USA). PCB orders are pooled and sent to Gold Phoenix in China for manufacture by-the-panel. The panels are split into individual orders and shipped James Fowkes. "I've found this process tends to take about a month, but can be as much as three months if it straddles the Chinese New Year. BatchPCB are apparently looking at finding another supplier to cover the gap. BatchPCB is the cheapest I've found for one-off PCBs if time isn't a factor, but you can be hit by customs charges when the boards hit the UK."

• seeedstudio PCB service

Seems quite cheap. They aggregate orders, so delivery time might vary.

• Sitopway

A Chinese based PCB supplier who works via eBay.

• Rush PCB

Based in the UK. New customer offer is £30 for up to 30sp inches 2 layer.

• Dorkbot PDX

This is a hackspace in Pittesburgh US who do a PCB panel every couple of weeks. 2 or 4 layer PCBs priced by the square inch.
