We want to sell all kinds of hackery things from a vending machine in our hacker space! 3D printed objects, usb sticks, mate straws (and mate), caffeinated snacks, arduinos, mesh routers, logic analyzers, lyophilized DNA (biohacking), dogecoins, ear plugs, headphones, batteries, etc! See the [http://hackpack.me hackpack project] for more inspiration. | |||

[[File:IMG 1426.JPG|thumbnail|The black vending machine (a.k.a. vending1) is nearly ready to use (Mar. 2016)]] | |||
There are currently two vending machines, one of which is ready to dispense product (as of March 2016). | |||
Still needed: | |||
* Product to dispense | |||
* A lock for the door | |||
* Something to direct the light from the fluorescent bulb so that it more clearly shows the product, rather than shining into the eyes of innocent bystanders | |||
* A user interface | |||
** some way to select a product | |||
** a mechanism for providing payment | |||
* A better place to put the trash and recycling bins that are currently blocking the front of the machine | |||
* perhaps "soup bowl" coils for dispensing larger items like soylent packs https://snackattack.sharepoint.com/Pages/APSNACKMACHINEPARTS.aspx | |||
For more information, ask [[User:Juul|Juul]] and [[User:Jerkey|Jerkey]]. | |||

The original hardware was wired to use diodes on a board of switches, where the price was set for each product with five on/off switches, worth 5, 10, 20, 40, and 80 cents. The user would press a button for the product they wanted. Since we don't want to use the buttons that way, we need to use triacs (electronic relays for AC) for each of the 40 product motors. We are designing a custom circuitboard to replace the binary coin-counter matrix with 40 charlieplexed triacs: | The original hardware was wired to use diodes on a board of switches, where the price was set for each product with five on/off switches, worth 5, 10, 20, 40, and 80 cents.
