Re: Remote pump control ideas.

Yes, but that's the wire for the antenna - we're not sure if the antenna itself is actually inside the box....

Re: Remote pump control ideas.

Not sure where the antenna is located exactly, but I was thinking of leaving this system in place as well as a sort-of backup in case something goes wrong with my super high tech setup :D

Thumbs up Re: Remote pump control ideas.

Not necessary in this case, but could be added later on....I also managed to score the user manual for the GSM boards currently in there thanks to this chap who installed them. It's HERE...

Re: Remote pump control ideas.

I managed to cook up something on my own after all - I've been at it for the past week. As always, I'm not a programmer so my code is most likely a disaster, albeit functional....I may actually share...

Red face Re: Remote pump control ideas.

I brought my arduinos with me today at work to play with this project a bit. I didn't get very far because I only have a Mega and some Minis and I didn't bring the programmer with me so I can't...

Re: Remote pump control ideas.

No idea, TBH, how it all operates and how it's hooked up - it's probably a LAN. We use this setup for CCTV IP cameras in another town - no actual "internet" there, just a LAN which connects together...

Re: Remote pump control ideas.

Naah, our company already ran the necessary cables (or maybe even fiber - don't know yet) to hook up each site to that town's network, so we'll have to stick with whatever can be done over a LAN/WAN.

Re: Remote pump control ideas.

Not to mention I don't know how long the cable is outside the box either, so a couple of more meters there too :D

This could get complicated, though it makes sense.....I have a limited amount of time to come up with a viable solution :D

Re: Remote pump control ideas.

Seeing how the positive lead next to it seems intact and it's the same thickness, I'd say it was simply a case of "mneh - good enough" approach and they just left it like that...I'll be sure to solve...

Re: Remote pump control ideas.

Ok, ethernet is indeed incorrect. INTERnet would be more like it - there's isn't actually a cable running between the two - each box has its own internet connection and we have to make them talk....

Red face Remote pump control ideas.

Good day folks. A task was given to me to redesign the control system for a pump system in a remote location. The idea is that there's a tank which has a float or some sort of switch/sensor to detect...

Re: Running a microcontroller in car - power supply aspects

Kinda running low on pins on the Mini TBH, though not a bad idea in the long run.

Thumbs up Re: Running a microcontroller in car - power supply aspects

Yes, turns out I was almost right: the specs (https://www.aliexpress.com/item/32979650248.html?spm=a2g0s.9042311.0.0.27424c4dFfeVqM) give a 27ohm resistance.

Re: Running a microcontroller in car - power supply aspects

Right, though that's assuming there IS a datasheet for these things :D

Re: Running a microcontroller in car - power supply aspects

Since the relay pulls 0.17a at 5v, I think it's possible to work out the resistance to be around 30 ohms, though this is on paper - haven't measured directly with a meter. Since it's a coil and has...

Alright guys, here's an update on this project and some pics of the board which is almost ready, component-wise at least. Yes, it actually took me this long to work on it some more - go ahead and...

Re: Bosch AL2215CV charger fix

Now that I look at the pictures myself, the colors indeed make no sense and I can't remember what I did there after so long. As I was reading my original post, I thought I combined two 15ohm...

Re: Raidmax RX-600 ringing noise and 0ms PG

Re: Xiaomi Laptop not detecting SSDs anymore

I though the same: SSD was inserted upside-down so the VCC pins got connected to GND and since there's bound to be a reverse-polarity protection diode onboard the SSD, it started conducting and...

Re: Dell 2700w j728n 3kVa UPS not starting

Try disconnecting the batteries and power it on without them. If not, it's troubleshooting time, so you may want to start your own thread and leave a link to it here as well since I'd be glad to hear...
