Components

The Hackspace carries a range of electronic (and other) components in stock. As a rule, members can use anything for free, as long as the cost is less than £1. However, if you're using more than £5-£10 worth of components a month, we'd appreciate a donation to cover those costs.

Purchasing

Please include a link to the item, preferably from Farnell, or it won't be ordered.

If you're a member of the space we'll happily order components for you and take advantage of bulk discounts/free shipping. If the component you request is cheap, we may order more than you need and bring it into stock in the space (if that's the case, then it's free as above).

Requests

• Arduinos (we should probably get these from Earthshine, but our budget is a bit tight to stretch to them currently -Russ)
• Miniature trimming potentiometers
• 4093 (four NAND Schmitt Triggers in one chip, useful for e.g. polyphonic square wave oscillators) (US stock - won't buy)
• NTE4017B ("decade counter"/10-step counter, useful for sequencers) (US stock - won't buy)

For Robert:

• 4N33 Optocoupler Transistor x 10 (we already have a reasonable substitute in the "optoisolators" drawer)
• 1N4007 Diode x 10 (1N4004 should be a decent substitute)

For Alex:

• Decade counter ICs x 2
• Hex inverting Schmitt trigger ICs x2

Links Needed

Please help by finding an appropriate link for the following.

• LEDs (varying, some good bright ones) +1 (we have loads of basic red/green/yellow etc ones)
• 12V 3A solid-state relay
• solid-core cable (RGBYKW) and multicore

Tools and equipment

See the Wishlist page.

Tool bits and pieces

Recently retired/thrown away

• spade-drills which had side of the spade drill broken sized 8, 10, 12 and 22 (2011/04)
• Down to the last hacksaw iron blade (2011/04) - 410 length
• Down to the last Pendulum Jigsaw saws of the non-T shape saws (2011/04)

Consumables

We're running low on:

• 555 and 556 timers. These are generally useful, we should always keep a few in stock.
• Logic chips. I think the 74HCT series is a reasonable place to start, but I'm not an expert here.
• Breadboards, 550 tie points, 270 tie points (caution: these are US parts, didn't find the same locally)
  • Global Specialties, while a good make, is more expensive and - as you mentioned - has to be shipped from the US at a £16 surcharge. May I suggest this local alternative.
