A couple of you have been asking about how the interlocks are progressing so I thought I’d quickly write down what I’ve done and what my plans are.
I started working on the interlocks a couple weeks ago during a week off. During that week I got to figuring out what was what and did a little bit of construction. I’m currently building 11 interlocks - one for each contactor we have. I didn’t make as much progress as I had hoped, I was only able to complete the connectors and solder the RFID readers. The jobs that still need to be done are as follows.
A replacement for the LED needs to be sourced. Any WS2811 or NeoPixel thingy should be compatible. Preferably with an inbuilt diffuser. I don’t anticipate any issues.
I’ve been having some trouble with the code, although I haven’t had an opportunity to sit down and work it out. I’ll be looking into it closer this weekend, time permitting. Once I get this sorted I’ll also be able to fix the front door. The code is on the HSBNE Github for those interested.
The 230V mains wiring needs to be done. I’m not an electrician so I won’t be able to do this myself. I plan to do these interlocks slightly differently to what we have now. Instead of splicing the interlock into the power cord on the machine I plan to set it up as a “smart extension cord”. This way interlocks can be moved between machines and it makes them less of a pain to install.
There’s some back-end to do on the portal but I’m not sure exactly what that is yet. I would appreciate a pointer from anyone in the know.
I had been hoping to make more progress on all of this but I’ve been a bit burned out from Uni lately.
As far as helping me out goes, assuming you’re interested, anything on the list is fair game. just let me know what you’re working on so we can coordinate our efforts. I’ll eventually need some help building all of the interlocks but I would like to have at least one working before we go crazy on building them
Final note, there’s been some talk about adding additional features to the interlocks, lots of great ideas floating around. For the moment I want to focus on getting what we already have deployed. There are machines that have been waiting for an interlock for longer than I have been a member and my goal is to get them turned on ASAP. After we have everything working nicely we can start looking at upgrades
