![]() Where are the fuses? If its just on the back in put OMG no. Now if someone is playing around with remote controls in your house and switching on lights and stuff, its great and I love doing this exact sort of bodge projects for the fun of it.īut in absolutely positively no way would I ever put that into an environment where I would need it to be reliable and safe.Įdit: you should submit this to r/techsupportgoreĮdit again: I just noticed you have exposed terminals and low voltage and high voltage intermingling without any isolation. No EMF protection and the wiring breaks so many rules of interference. There is no inrush limiting or circuit protection. ![]() Using wirenuts is asking for trouble in that sort of setup. There is no safe isolation under the boards either. Those relay boards are not rated for what they are using them for. I like the idea but the execution is not something I would trust for any level of reliability. And then only to have the open source project fail completely during personnel changes because the undocumented train wreck can’t be easily managed by a new comer. I’ve also seen organizations struggle on implementing open source projects for weeks or months only to learn that an easily deployed commercial product is under $5,000. I understand making a one-off in a pinch, but some shops are religiously devoted to this asinine practice. You spent 15 minutes making something incorrectly that you could have purchased for under a $1. Most of the time I see a train wreck burning hundreds of man hours to save 10’s of dollars.Ĭase in point: People who make their own patch cables in standard lengths using solid core cable. I’ve seen some really creative DIY and some very appropriate cost saving open source projects. Placing all of the obvious safety and reliability issues aside, I still can’t fathom why so many small shops think DIY or open source is “saving” them money. and a basic metered PDU with 20 outlets if going to be in the $200 range. So you're looking at $345 for parts alone. Not sure about the 2 big AC side protection relays nor the power brick but going to guess $30 and $20 The thermal couple like $35 and the isolation 4x box is $20. I know some said that at 10 AMP in the comments. The relays are PhidgetInterfaceKit 0/0/4 the $50 per relay. the main controller is Phidget SBC4 at $120. This design though would cost around the same as a PDU. Fuses across the X,Y,Z phases, and really crappy microcontrollers and a piss poor buck converter. you could have a functional 16 channel relay device for under $70.Īnd Most PDU's that I have torn apart are pretty much just run of the mill Relays. Pi zero W, or some other low spec SoC is also in the $20 range. But if you wanted to do this on shoestring budget relay boards are somewhere in the $20 range. not sure about this design unless they literally had most of the components already. ![]()
