The gray and gray/yellow drawers on the back wall are the electronics store. These components are for sale to anyone who has a use for them. Place payment in the drawer labeled with bold dollar signs and the word "payment" near the lower right.

If you don't know what a component costs, find it on http://mouser.com/ and add 10% to cover shipping. If you need change, you can make it with funds from the soda payment cup in the fridge. However, these funds go to different people, so don't just drop money in the wrong cup.

Welcome to the electronics room! If you don't know what something does, please ask. The Zone Warden is [[User:Nbezanson|Nate B]]. The zone warden sign is here: http://i3detroit.com/wi/index.php?title=File:ERoomZonePosterWithMoney.docx
  
Some members may have components or salvageable parts that they will share but which may not be part of the electronics store. Use your judgment when taking those things.

If you wish to donate components to the store, feel free to do so. If it is clear where they should belong, just drop them in. Avoid placing them in an unlabeled drawer or bin. If you don't know where something belongs, ask [[user:nbezanson|Nate B]], or leave a note indicating your intent and he will find or make a place so the parts can remain organized.

Some drawers are now labeled with prices, usually a cost "C" which is what it costs us to restock, and a second value for comparison, like "RS" for Radio Shack's price on an equivalent item. These are just FYI, and all we ask is that you cover the cost. Any markup beyond that is up to you, but you can be pretty generous and still save a bundle compared to retail. A buck here and there helps the selection continue to grow!
  
Parts on this list have been ordered and should be in-stock. Add rows if you contribute stuff, edit if things go out of stock.

If there's no cost label and you don't know what a component goes for, find it on http://mouser.com/ and add 10% to cover shipping. If you need change, break your bills with change from the cup in the fridge. However, these funds go to different places, so don't just drop money in the wrong cup.

Welcome

Welcome to the electronics room! If you don't know what something does, please ask. The Zone Warden is Nate B. The zone warden sign is here: http://i3detroit.com/wi/index.php?title=File:ERoomZonePosterWithMoney.docx

Tools in this zone:

Edsyn Loner soldering stations (the black ones directly above the bench)

Weller WLC-100 soldering stations (the orange ones on the top shelf)

Tektronix TDS 460 digital oscilloscope

BusPirate

Saleae Logic analyzer

X-Tronic 4000 series hot-air rework station

MFJ 269B Antenna analyzer

Etiquette

As with all of i3, leave nothing on the workbenches. Your project can be stored in a labeled box in the electronics room if you are actively working on it and it is small. Otherwise, take it home or use regular member storage.

If you were trimming or stripping wires, consider sweeping before you leave.

Store

The gray and gray/yellow drawers on the back wall are the electronics "store". These components are for anyone who has a use for them. Place payment in the drawer labeled "Gives us the money Lebowski" near the middle. The image on the right is an approximate map to the component locations as of late August 2012. Ping Nate B for an update if one appears to be needed.

Some drawers are now labeled with prices, usually a cost "C" which is what it costs us to restock, and a second value for comparison, like "RS" for Radio Shack's price on an equivalent item. These are just FYI, and all we ask is that you cover the cost. Any markup beyond that is up to you, but you can be pretty generous and still save a bundle compared to retail. A buck here and there helps the selection continue to grow!

If there's no cost label and you don't know what a component goes for, find it on http://mouser.com/ and add 10% to cover shipping. If you need change, break your bills with change from the cup in the fridge. However, these funds go to different places, so don't just drop money in the wrong cup.

If you wish to donate components to the store, feel free to do so. If it is clear where they belong, just drop them in, adding labels as necessary. Avoid leaving anything in an unlabeled drawer or bin. If you don't know where something belongs, ask Nate B, or leave a note indicating your intent and he will find or make a place so the parts can remain organized.

Reference prices for bulk items: Rather than tagging each value individually...

Item Price
1/4-watt resistor: 2c
1/2-watt resistor: 5c
High-wattage resistors: Ask!
3 or 5mm LED, red/green/yellow 5c
3 or 5mm LED, white or blue 10c
High-power LEDs Ask!
Any ceramic cap 5c
Electrolytic caps Use Mouser, or ask
Zener diodes, up to 1W 10c
1n4xxx diodes 5c
Other diodes Use Mouser, or ask
0.100" Harwin housings, 1 position 2c
0.100" Harwin housings, 2 positions 15c
0.100" Harwin housings, 3+ positions 25c
0.100" Harwin crimp pins 7c
