A sizable inventory of electronic components was purchased for
|
|
|
|
|
|
[Hackersmart](Hackersmart "wikilink"), 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.

|
|
|
|
|
[Mouser](http://www.mouser.com) and [Digi-Key](http://www.digikey.com)
|
|
|
|
|
|
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](http://www.mpja.com) 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

|
|
|
[All Electronics](http://www.allelectronics.com/) 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](http://www.bgmicro.com/) (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](http://www.goldmine-elec-products.com/) has a
