I am looking for a freelancer who could take on a small proof-of-concept project ('spare-time job'). Local to Palmerston North/Manawatu would be great but not essential.




Would require experience in Python.




High level overview of the project:


Design an application which presents a 2 x 2 Button Matrix, populated with 'Pre-Set' Actions.


The application would have an "Information area" above the button matrix


Upon the user 'touching' the Button of choice, send a command via USB/Serial or IP to an API-Spec that controls an external device


Device to be used is a Raspberry Pi with 7" Touchscreen




For the moment doesnt need to be "pretty"; just need to see if it can be done.

Not interested myself (unless you've got a lot of money to spend on this money-mouth), but it seems pretty straightforward to me. The whole thing could be done as a web page without any programming per se.


"Sending a command" needs to have some kind of specification as to what a command is and what parameters are passed and what protocol to use for communicating, but if you're looking at turning on/off a light or whatever that could be done via a web service.

Fair enough. Its generally targeted at charities so its not a "money-maker" but rather a way to help out with digital transformation and being different.


The commands need to be sent to a "Payment Device" over Serial/USB or IP (well those are the ones we can use). We have another solution for a different product and we had to enable "allow insecure content" within Chrome to send the commands we needed to send; was trying to avoid that potential limitation. However I do product and not code so more than happy to be corrected if theres another way to achieve the same outcome.
