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.

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).

Purchasing

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

Items with a Farnell item will be ordered with the next batch, items not in Farnell will only be ordered from time to time.

Requests

4051 Analog Multiplex/DeMultiplexer @Farnell x 4
Positive photo resist spray @rapid (free del over £35)
Stripboard, e.g. [1] unless there are cheaper options. There are: [2]
NPN transistors (ONE LEFT), atm we stock BC547BG but these are much cheaper [3].
Low Power MosFETs [4]
16MHz crystals (farnell) - cheaper from Rapid
Arduinos (we should probably get these from Earthshine, but our budget is a bit tight to stretch to them currently -Russ)
Miniature trimming potentiometers
- 10K
- 100K
- I have put a selection of multiturn trimpots in a translucent plastic compartment box, currently on top of the component drawers in the main room - artag.
CD4050BE 5v <-> 3v3 level shifter
MCP23008 I²C IO expander
General box of various M2-M10 nuts, bolts and washers. (RS Components)
- 650 piece nylon metric nut kit
- 600 piece nylon metric screw kit
- A4 stainless steel metric full nut kit
- A2 stainless steel metric full nut kit
- ISO metric ZnPt steel machine screw kit
Resistors:
- 680 Ω (LED with 9V)
- 2k2 Ω
Capacitors:
- 22pF
- 47nF
- 10n (103)
- 100n (104)
- 0.1µF - way cheaper from Rapid, if 25V is enough [5]
- 0.22µF
- 0.39µF
- 0.47µF
- 1µF (small)
- 2.2µF
- 10µF
- 22µF
- 100µF
- 220µF
Tools:
- Cheap multimeter (eBay)
  - Please don't buy these. They're a waste of money. Russ has bought a couple of very decent fluke meters, I've also donated a brand new multimeter which i paid something like £25 for. Treat these nicely and they won't get broken+we won't need to buy these pieces of shit. - alecjw
- Wire cutters
Helping hand magnifier (the ones we have have only 1 clip each)
Prototyping:
- Jumper wires (eBay) - the ones we have are running low and are not the easiest to insert.
- Spot face cutter - less than a third of the price at Rapid
- Breadboard (Rapid)
- Banana leads (Rapid)
LM368N-1 Power Amp
NE5532 Op-Amp
ADS7822P ADC
ATMEGA168
ATMEGA328 (much cheaper on Mouser)
LM358P
PIC16C84
7-segment LED display green
IR Diode
LM317T variable voltage regulator
3.5mm mono jack
3.5mm mono socket
piezo buzzer
DC Jacks ("cigar plugs") for our cigar sockets, can't figure out what type it is...
Reed switch
Schotty diodes
Crocodile Clips
Spool of single core wire, current one is getting fairly low
Header pins in a variety of formats. 1 x 20, 2 x 10 especially. AFAIK the component trays have no header pins in them right now. Associated sockets would be good too.

Previous orders

DO NOT EDIT THE "PREVIOUS ORDERS" SECTION

This section is to keep track of past orders.

If you want to report stuff that's running low or missing, do so in the Requests section. Making a mess of this page won't help us ordering the right components.

June 2013

Hex inverter CD4009UBE @Farnell
3.5mm stereo jack
4093 (four NAND Schmitt Triggers in one chip, useful for e.g. polyphonic square wave oscillators) (now UK stock)
4017B ("decade counter"/10-step counter, useful for sequencers) (now UK stock)
555 and 556 timers. These are generally useful, we should always keep a few in stock.
Bits for the Oki PS-900 soldering station. PHT or SFV series should fit, and be hot enough for toxic-flux lead-free solder.
chocolate blocks
200 x 2.5mm Cable Ties Delivered
NPN transistors. There was a bag marked 2N3904. I think that's a reasonable Farnell part to replace it with.

May 2014

Desoldering braid (get 4) Farnell
9v PP3 batteries Farnell
Medium (1mm) (get 2) soldering wire Farnell
Fine (0.5mm) (get 2) soldering wire Farnell
NPN transistors 2N3904.
Chocolate blocks Farnell
SRAM CMOS 64K, 623308, DIP28 Farnell
TEXAS INSTRUMENTS - MAX232N - IC, TRANSCEIVER, 5VFarnell
RESISTOR, 2.2K, 0.125W, 1% Farnell
