I've not build it yet. I shall post pics once I have built it. I posted a pic in the first post using the manage attachments thing. Got to love the ease of use of this vBulletin software. A word of advice to the forum admin, don't upgrade to the new vBulletin it sucks big time :)
Thanks for your reply. Yeah the casing has connectors and thanks for clarity there :)
I will be testing the water to see if it does conduct. It is basically tap water with chlorine removed. It does have under 0.1 ppm of ammonia, nitrites and nitrates. If the water method does not work, I will...
I will check them often :) Most likely once every week or so.
I've also wired two smoke alarms up to alert me if the water level increases. Essentially if the water rises to the top of the waterflow, the wires which are located about 3 mm away from each other will have the circuit completed by...
I am still lost lol. Forgive me here, I am a total dimwit when it comes to electrical stuff.
I won't be using any tape at all. The cut live wire will be attached to the relay. That is the only AC current exposed as the neutral and earth wires will both remain intact. I am not cutting the whole...
Hi, thanks for your reply.
Do you have a junction box you recommend? I intend to have the relay and everything else concealed in casing. The neutral an earth wires will not be severed at all. Only the live will be cut and that will be attached to the relay.
Apologies if I am misunderstanding...
Hi thanks for your reply.
It is this 12V DC adaptor I've got.
**broken link removed**
The transformer would be inside that. It is basically the same as a phone charger or the power cord for a low wattage toy.
I will have 3 of the floats in a series and that way I have total redundancy...
Thanks for your reply.
The 12V DC adaptor actually can run at 3V all the way up to 12V. When you mean isolated, what do you mean? I am only going to use it to complete the circuit to the relay. Sorry for anything obvious I am missing.
I am actually thinking of wiring 2 or even 3 float valves...
Hi there, first off, your site is epic. I have you guys bookmarked and the ideas you come up with are just epic.
I have decided to dive into building something but just want clarity before I go forward. I want to use a float inside my aquarium to basically switch a pump on and off. Safely...
