A sizable inventory of electronic components was purchased for [[Hackersmart]], with the goal that the unsold portion thereof would seed HacDC's electronics lab. This has come to pass, and the components are arranged on a pegboard by the soldering desk. This page is to explain what's available, how much it cost, where to get more, and as a place to request additions.

This list has not been actively maintained in some time.  We are not able to resell items or run a store because that would require us to collect and pay DC sales tax.  So, think of the parts as office supplies that we have stocked.  If you use something, please donate an appropriate amount to the tip jar.

=== Suppliers: ===

[http://www.mouser.com Mouser] and [http://www.digikey.com Digi-Key] are the "big guns" of the hobbyist and small professional electronics market, with breathtaking inventories, fast order fulfillment, and sophisticated websites. Digi-Key adds a handling fee to orders under $25.

[http://www.mpja.com Marlin P. Jones & Associates] is a smaller web retailer specializing in power supplies, but with a fair assortment of other stuff too. Their prices on breadboards are hard to beat. (Thanks [http://serialwombat.com/ Jon] for that tip!)

[http://www.allelectronics.com/ All Electronics] has been in the surplus electronics game for a long time, with a small newsprint catalog that's a staple in many geeks' bathrooms. As with any surplus dealer, their inventory is constantly in flux, and sometimes they have really amazing deals.

[http://www.bgmicro.com/ B.G. Micro] (known pre-9/11 as "The Electronics Mecca", now calls itself "The Electronics Supplier") is a small mostly-surplus dealer whose bright yellow catalog offers Texas humor mixed with eyestrain. Their shopping cart software is chaotic evil, but they have great prices, particularly on industrial stuff like thermal fuses and zener diodes. 

[http://www.goldmine-elec-products.com/ Electronics Goldmine] has a better selection of motors, magnets, and boxes than almost anyone else. They offer "GoldPaks", grab-bags and assortments of surplus (sometimes take-outs) hardware, some of which are so-so deals and some of which are simply jawdropping.
