Welcome to the Bristol Hackspace Wiki

NOTE

This page is out of date, see Hackspace Proposals for details on how to buy equipment under £300


One of the benefits of being a hackspace member is that you can use group equipment!

See Our tools and facilities to see what we already have - it might be that what you want already exists, but isn't immediately visible.

Buying new equipment

If you need some equipment that we don't already have, please follow this process:

  • Add it to the Wanted list in the next section. More expensive things are more likely to be purchased if interested users pledge some of their own money towards it, so please offer something if you can. Don't forget VAT and P&P!
  • Post to the mailing list announcing your proposal to see if others are interested, in which case they should add their names and (optional) pledge.
  • If it doesn't cost much (or much more than is pledged) go ahead. Otherwise check with our treasurer David Wyatt that we can afford it. See the expenses claims page for how to actually claim the money back.
  • If there's enough pledged to buy it outright then you can do it directly; put any change in the Hackspace petty cash and not go through the Botlab account. However it makes it easier for us to show that Botlab is a not-for-profit organisation and present proper accounts if it goes through the Botlab account.
  • If it's bought, don't forget to add it to the Our tools and facilities page!

Wanted Things

G10-improvement-wish-list

Some speculative ideas were mooted on the Arduino workshop profit shopping list. David W also carried out a Doodle poll with the following results from 9 respondents as of 27/6/2012 (the question was “Please select whether you think you would actively use the following if the Hackspace had it”):

  • Woodworking lathe: 4
  • CNC mill: 2
  • Manual mill: 2
  • Manual lathe: 2
  • Microwave: 2
  • Kettle: 2
  • Multimeter with frequency & capacitance: 2
  • Fridge: 1
  • Screwdrivers: 1
  • Screenprinting equipment: 1
  • Coffee machine: 1
  • (working) knitting machines: 0
  • Welder: 0

Screwdriver set

This was taken from the old Wanted list on the home page. Is it a request that we have *more* screwdriver sets, or a holdover from a dark past when we didn't have a screwdriver set at all?

Matt says do we really need more screw drivers? It seems to me we have loads!

Multimeter with frequency and capacitance ranges (e.g. Vichy VC99)

The Vichy VC99 on Deal Extreme (may be out of stock):

Lady Ada's recommended pocket multimeter (with frequency and capacitance):

* Matt puts in £10 for one

Curve tracer

The Vichy 4070 on Good Luck Buy:

And some notes on the meter from the Embedded hardware Guy:

Pulse generator

Taken from the old Wanted list on the equipment page

Logic analyser

Taken from the old Wanted list on the equipment page

Marcus says: I have an HP 16702A logic analyser main frame the 'space can have. The problem is it doesn't have any modules. To be of use you would need something like the HP 16752A logic analyser module. These kind of things are available on ebay for around one hundred quid, or possibly someone could blag one from Agilent or some of the test equipment hire companies.

Spectrum analyser

Taken from the old Wanted list on the equipment page

Matt says, do we need this now we have the new scope? The new scope does some amount of spectrum analysis.

Hot air rework iron

For SMT soldering, a hot air iron is very useful. It's like a mini heat gun, very handy for getting chips off boards, and localised heating. Ones on ebay are around £40-£45 http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=atten+858D&_sacat=See-All-Categories

  • Ginjaian puts in £5

Digital calipers

These can be had for £10 from Maplin until 10/7/2012… Note that some models of digital caliper can be wired up to a digital interface and read out on (say) an Arduino: * http://www.compendiumarcana.com/caliper/ * http://robocombo.blogspot.co.uk/2010/12/using-tis-launchpad-to-interface.html

Safety equipment

We should obtain some safety equipment e.g. glasses - any other requests? (Perhaps hearing protectors, dust masks)

http://www.hindleys.com/health-and-safety/ has some cheap lab/workshop safety supplies

AVRISP Mk2 programmer

Matt would find this useful for TPI programming. Matt puts in a 10 pound pledge.

Paul has an official Atmel USB one which is £30.

Cheap clones are available - apparently $3 from Hong Kong. Russ has a clone one and a DIY HV programmer, and Dave has a clone.

Garth recommends http://www.atmel.com/tools/AVRJTAGICEMKII.aspx which is expensive ($299) but has a JTAG/DebugWire interface to do debugging and step through code. An alternative is the (apparently legally reverse engineered) http://www.ebay.co.uk/itm/USB-ISP-JTAGICE-MKII-CN-Metal-Version-AVR32-Studio-Emulator-Metal-Box-Anodise-/290653874708?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item43ac522a14 (£59).
