Components Store

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 costs, where to get more, and as a place to request additions to the store.

Pricing is intended to cover our cost and shipping, and to make the store self-sustaining like the fridge. These are internal "member's prices", and may not reflect what we charge at conferences, where there's an understanding that purchases actively help HacDC.

Suppliers:

Mouser and 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.

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 Jon for that tip!)

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.

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.

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.
