I’m looking for one or possibly two people who’d enjoy hacking the vending machine AND getting paid for it.
The circuit that’s been built correctly talks to the vending machine via the Multi-drop bus (MDB) protocol. The circuit can see messages from the VMC to the peripherals.
I need you to finish the system such that:
(phase 1)
- the hardware provides an ethernet connection out of the machine for internet connectivity
- the software can imitate a cashless peripheral (card reader) and add credit to the machine
- the software can offer an interface encrypted via PGP or some other SSL
- the software can process instructions to add credit
(phase 2)
- the hardware can also talk to the DEX protocol audit system
- the software can process requests for audit data & transaction history
- the software can install patches on demand
- the breadboard circuit is converted into a 2 layer PCB with through-hole components
- the hardware is contained in a 3d-printable case
This project will be closed source and closed hardware. I have an NDA with a non-compete.
Because of the machine’s location only VHS members can apply.
Please PM me your qualifications, your estimate of the cost, your estimate of the time, and any other details you think might be relevant. I am looking to contract ASAP so don’t hesitate.
Here are some helpful links about the tech involved.
