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).

Links Needed

Please help by finding an appropriate link for the following.

• new tips for the general soldering irons! (Not at space so can't check models, if this matters)
• "brass sponge" for cleaning soldering iron tips.[1][2][3]
• A couple of stiff brushes - to make cleanup around MIll and Lathe easier. Perhaps with some chain to tie them to the table.
• LEDs (varying, some good bright ones) +1 (we have loads of basic red/green/yellow etc ones)
  • you can get LEDs dirt cheap off ebay. i bought 500 blue LEDs for under 7 quid a little while ago. if you want to go with a more reliable brand, green LEDs red LEDs blue LEDs bicolour LEDs found after a quick price check between rapid and RS. i haven't worked out how to use farnell's website yet so i can't comment on their prices.-alecjw
• 12V 3A solid-state relay
• solid-core cable (RGBYKW) and multicore
  • I have some reels of wire (stranded and coax - none solid) to bring in so stick to stocking up on solid for now - artag
  • http://www.rapidonline.com/Cables-Connectors/Equipment-Wire/Equipment-Wire/1-0.6mm-Single-core-equipment-wire-on-100m-reels/62317 seems to be the cheapest, having done a quick price check against RS and Farnell. I have 2 reels at home: orange and blue - can bring them in. -alecjw

Tools and equipment

See the Wishlist page.

Some tools we could regard as consumables; get cheap ones and replace them frequently. E.g.:

• screw drivers

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:

• Logic chips. I think the 74HCT series is a reasonable place to start, but I'm not an expert here.
• Some banaplugs or already wired up banaplug wires in the usual colours and length.
