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).

1000μF 6.3V | 0.1/0.22/0.33μF TANT |          |  Trimmer 22pF
=== MCUs (ATTiny) ===
 
This section added by Daveb who is looking for more info...
 
see [http://www.atmel.com/Images/doc4064.pdf ATMEL's AVR and AVR32 - Quick Reference Guide] for useful info.
 
  
ATTiny rather than an ATMEGA as it is smaller and lots cheaper or would use an arduino or similar.
+
1000μF 16V  | 0.47/1.0/1.5μF TANT  |          |
ATTiny rather than other MCUs for good free tool (GCC etc) support.

1000μF 25V  | 2.2/3.3/4.7μF TANT  |          |
  
Doing searches on Farnell reveals lots of choices, with big price breaks (~40%) for 10 and (~20%) for 100. Price seems to roughly scale with pin count or maybe chip size.. but there are anomalies. It is worth picking a chip and buying a few.  But how to choose the chip??

==Current pot==

Approximately '''£35''' on 3/OCT/2015 Stored in the big safe
  
Points that matter to me..
+
==Purchasing==
* enough RAM for interrupt vectors, global state variables, C stack, local variables and interrupt stack
 
* excess code space for diagnostic code
 
Prototyping
 
* a few excess pins to allow for in-crcuit reprogramming and debugging (which i think means dont use MOSI,MISO,SCLK or RESET in the application)
 
  
An 8 pin dip has 2 pins available to the app (4 debug plus vcc and gnd), while a 14 pin dip has 8 app pins? Four times the app space for under 2x the size:)

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).

Add items to one of the lists below if you'd like them to be stocked at the Hackspace or if you see that something's running out and needs reordering.

Catalogue of Components

Below is a catalogue of the components available in the space.

Purchasing

Fill out this form. ☜

Once we get enough components to order, we'll order them. You can view what was ordered on this spreadsheet. Please add a link for the item (with the quantity required). Preferably use one of the following suppliers, whichever's cheapest. If you can't find what you need on these sites look for an alternative supplier, ideally one offering free delivery.

  • Farnell - Main UK Site
  • CPC - Farnell white label - larger items are sometimes cheaper here than on the main Farnell site
  • Rapid Online - As yet untried, but looks cheaper than Farnell

Please do not edit the wiki as a way to comment on other people's requests - post to the mailing list instead.

Urgent Requests

Please only add things here if you think it can't wait until the items on the standard requests list get ordered. Also, mention it on the IRC channel or mailing list to make sure that someone with access to the Farnell account sees it soon.

  • Replace this line with your request

Standard Requests

Items on this list will usually be ordered approximately monthly from Farnell/CPC/Rapid Online or as soon as there's enough on the list for the order to be eligible for free delivery. Items from other sites where there's a delivery cost may get ordered more sporadically.

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 one of the requests sections above.
