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.
Please do not edit the wiki as a way to comment on other people's requests. If a component needs ordering, move it to the top of the relevant list, and date the request.
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).
Urgent Requests
Please only add things here if they are urgent, and ask on the IRC channel to make sure that someone with access to the Farnell account sees it.
Standard Requests
Items with a Farnell item will be ordered with the next batch, items not in Farnell will only be ordered from time to time.
Older Requests
These are various requests made at some unknown point in the past. They'll eventually be removed or ordered.
- 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
- CD4050BE 5v <-> 3v3 level shifter
- MCP23008 I2C IO expander
- General box of various M2-M10 nuts, bolts and washers. (RS Components)
- Resistors:
- Capacitors:
- 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)
This section is to keep track of past orders. DO NOT edit this section unless you have just made an order.
If you want to report stuff that's running low or missing, copy the relevant item to 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
