This is the place to list any info about our vending machine.
As of July 2012 the machine is out of service. Something about it costs too much to power + keep soda/pop cold, or something. But the point is it's not plugged in and won't give you soda. So don't feed it your money. Feed your money directly to Noisebridge, instead!

Making a Purchase
Everything is $1.00. The machine accepts dollar bills, quarters, nickels and dimes. Insert money and make your selection by pressing its button. If the orange light is on it's sold out. If it doesn't vend, try holding the button in longer. If it still doesn't vend, then you can either chalk it up as a donation or open the machine to retrieve your selection.
Opening the machine
The key is on the top and the keyhole is right under the bill acceptor. This unlocks a handle which pops out. Unscrew that for a decent number of turns, then the front panel opens like a refrigerator door with the hinge on your left. You will need to lift the door to open it, and especially to close it.
Stocking the machine
If you open the machine door, there are 8 slots for stocking beverages. They are labeled 1 through 8 which correspond to the order of the 8 buttons on front used to select your beverage. Slots 1-4 are "wide" slots that hold 60 cans each, while slots 5-8 are narrow and only hold 34 cans each.
It helps to load in two cans at a time (stacked top to bottom) into each slot in order to be able to fill each slot to max capacity. For the narrow slots, each layer of two cans will stack almost perfectly atop the previous two. For the wide slots, each layer of two cans will stack atop but to the side of the previous layer, alternating to the left and right with each layer.
I've had one can get smashed up by the machine when I loaded a single lone can incorrectly last atop the stack. To avoid this, try to stock an even number of new cans at a time, so that you are always adding two cans at a time. If you end up with only one can for your last stack, just vend one can from that stack to make a pair for the top.
If you are just adding more product to partially stocked slot, you need only to stack it correctly atop the current stock. However if you've stocked up a slot that was previously emptied/sold-out, you need to vend that slot until something comes out to "prime" the slot if you will. (In other words, if you loaded something in the previously empty slot #6, you should take some quarters or a dollar or two from the machine and keep buying one until a can comes out the door. Once it's dispensing each time you can load back in the "test" sodas as normal.) Close the door all the way, lock it and return the key.
Purchase Support Info
We bought the Machine from Gary (not sure of his last name)
We have a 90 day warranty starting 1/4/2011

Service manual for our vending machine (Dixie-Narco model DNCB 368)
Lightbulbs are 5' fluorescent with a single prong on each side. Part # when ordering is F64T12/D. City Lights is the closest place to buy these. They are on Folsom between 11th St. and 12th St. Phone number is (415) 863-2020. Neither Lowes nor Discount Hardware carries this type of bulb.
On January 15, 2010, the ballast that came with the machine was tested and found to work. Ballast is located directly underneath the drink dispenser tray. Ballast mounting plate is held in by three phillips-head screws
Please hack this machine gently and with confidence. We'd like to keep it working and stocked so it can earn money for Noisebridge. Failed Hacks that result in us spending the vending profits to fix are not excellent.
Mitch added a connector to the vending counter which will switch 110V AC briefly whenever a can is vended.

Actual Problems and Possible Solutions
- Problem:Electrical usage
- Is this even a real problem?
- Possible solution: a timer so we don't have to run the machine all the time:
- I have one of these and they work ok: http://www.google.com/products/catalog?q=sylvania+timer&um=1&ie=UTF-8&cid=17676369476629548940&ei=oi4STeCEEILGsAOH8rXdAg&sa=X&oi=product_catalog_result&ct=image&resnum=7&ved=0CDYQ8gIwBg#
- This won't really help. Because of basic thermodynamics, the compressor needs to run a certain amount: if the duty cycle is low enough to save energy, the drinks will be warm. Trust the thermostat! However, a timer could possibly shift the time the compressor runs to put the noise in the wee hours of the morning.
- Also, make sure any timer switch you use is rated for at least 11 amps, and I would say 15 to be safe! Jtfoote 05:27, 5 January 2011 (UTC)
- Possible solution: The manual seems to describe timer features built in to the machine. More research needed.
- Solution: VendMiser... http://www.energymisers.com/ Turns the machine off when no-one walks past for 15 min, but will keep the compressor running at regular intervals so things stay cold. Typical energy savings is 46%.
- Problem:Noise. And not the good kind. The "gets-really-annoying-really-fast" kind.
Possible solution: A high tech noise dampening leopard print slipper was placed between the noisy vibrating bits. Is the noise still offensive?
- Possible solution: The source of the noise is the fan for the compressor. It's really hard to get at the fan to try and correct the problem, but Jared and Robert carefully slide out the compressor assembly to try and accesss the fan. We didn't get total access to the fan but were able to remove enough screws to bend some of the metal around the fan further from the fan region... this seems to have helped with the noise......for now.... We didn't replace all the screws and bolts for fear of making the noise return but they are inside the money bin in the machine.
How to contribute
Buy some drinks and either leave them on top and they'll be loaded in or if you're feeling ambitious load them in yourself.
This is where we'll keep a record of the money 'earned' by the vending machine, the money spent on product, and the money donated to noisebridge and any other costs that come up. Please put "DONATION" in the list when you donate the stock of the vending machine to noisebridge.

Goals and Future
The goal of this project is to generate money to support noisebridge as well as give clarity and an obvious way to support to noisebridge to the "walk-in" crowd as well as the noisefolk.
Depending on the success of the soda machine it would be nice to have other premium vending machines that vend possibly healthy snacks, computer parts, arduinos etc.
