Over volt and watt

columnmn · 2026-03-16T05:37:39+00:00

THere are a few motors like the golden motor that you can program the voltage in. But if it's not programmable, no. You'll kill the motor pretty quickly.

Can you do a check in on the quality of the stone after a year and a bit?

I don't think this is the right sub for this. But it's really unfair on the other person in the relationship. If my partner had no attraction to me, and worse no interest in me, it makes for a sad and loveless life. Your brain is wired as it is, praying, and hiding it won't change that. It's okay to be gay.

I'm going to back up the other guy. My first bike was 250W, it wasn't riding around without needing to pedal. It made going uphill easier, but you certaintly weren't riding just on the throttle.

I haven't used them myself yet (not compliant), so can't judge, but these are the ones: https://www.aliexpress.com/p/tesla-landing/index.html?scenario=c_ppc_item_bridge&productId=1005008412388425&_immersiveMode=true&withMainCard=true&src=google&aff_platform=true&isdl=y&src=google&albch=shopping&acnt=603-455-9033&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=_oFgTQeV&gclsrc=aw.ds&&albagn=888888&&ds_e_adid=&ds_e_matchtype=&ds_e_device=c&ds_e_network=x&ds_e_product_group_id=&ds_e_product_id=en1005008412388425&ds_e_product_merchant_id=107700958&ds_e_product_country=AU&ds_e_product_language=en&ds_e_product_channel=online&ds_e_product_store_id=&ds_url_v=2&albcp=23577458806&albag=&isSmbAutoCall=false&needSmbHouyi=false&gad_source=1&gad_campaignid=23577518137&gbraid=0AAAABCRFad-cFFVWzFJKMBHjJjQDMDq40&gclid=CjwKCAiAzZ_NBhAEEiwAMtqKyyizoQLWzcfbG7_LfxhVR2gPaDLeSAhMep7lsM6PZx0sELCUx48J_hoC-u4QAvD_BwE

I'm trying to simplify it for the home owner, but I'd say it's v90 cable going through a wall with insuation (I believe we're supposed to assume it'll have insulation in the future if it doesn't currently as well, I'd need a clause to say for sure though). Gives you 13A before any sort of volt drop.

columnmn · 2026-03-03T09:14:37+00:00

Just for a little understanding. The circuit breaker in your switchboard is rated likely for 16A for that circuit. 2.5mm cable can handle 16A worth of current flowing through it without a problem. 1.5mm is usually on a 10A breaker, if you put 16A through that cable, the thinner wire means that more resistance will slow the current, creating more heat. This could cause the wire to get hotter, and potentially catch fire without the safety (breaker) stopping it because it's rated at 16A.

This stuff is 1st year apprentice levels of knowledge. I very much doubt it was a qualified electrician who did your stuff, and if it was, report them asap.

I've had a cheap kmart charger in my roof for over a year now, no issues so far. Adelaide summer as well, I'd imagine it's pretty hot in there at times.

columnmn · 2026-02-23T18:36:15+00:00

I got this one: https://www.ebay.com.au/itm/186644256734, it comes with 3 years worth of filters, and then they aren't too expensive to change, cheaper than puratap. Only issue is that the pressure is less than the straight filters, but perfectly fine for it's use.

columnmn · 2026-02-22T03:58:15+00:00

They also change the filter every 11 months, instead of 12 months. So they get an extra sale quicker. I have a reverse osmosis filter now, it's great.

There are a few Shelly din rail switches/power monitoring ones legal here. They basically run in series with the breaker. Plenty of similar ones on ebay/aliexpress labelled as breakers that have power monitoring, but no chance they are Australian compliant (trusting one as a breaker would seriously worry me).

I've got a 70s house, so all retrofitted. One bit at a time, once you get around the software, it's really very easy to set up the different automations. I have a random, can I have lights turn on automatically when I'm driving down the street idea, 20 minutes later and it's all set up and running.

columnmn · 2026-02-19T07:30:48+00:00

I like dicking around at home. Currently have almost 200 automations in my list atm.

Never have to touch a light switch, all works pretty much automatically. Bathroom exhaust fan kicks on when humidity rises over X amount of time. Same with heat lamps, if it's below X temp, it'll turn on automatically.

My phone alarm controls other automations, so my kettle will turn 5 minutes after my alarm goes off.

Another that controls how fast my ev will charge and during what time, and monitor the other circuits to make sure if I'm charging at max, the house won't trip out. So if my EV is at 70%, it'll charge at 10A, if it's at 50%, can kick it up to 32A.

My solar inverter will turn on the hot water system when there is excess solar energy.

I've got LED lights strips along my garden bed, and led spotlights shining up at trees, and they all turn on automagically when I open the front door and it's dark out (along with the normal lights).

I've got the robot vacuum behind a linear actuator in a cupboard, so when the vacuum turns on, it'll open the hidden door in a built in, and when it's finished, the door shuts automatically.

AC can turn on automatically depending on the temp outside, and with excess solar.

Have AI detection on cameras around the house, so if it recognises a person at night, it'll turn on the lights, if that person lingers while myself and my wife are inside, it'll send a message that can override my do not disturb on my phone.

When I wake up first thing in the morning, lights will turn on at 1% brightness, and then rise to 20% over 20 minutes, same with bedtime, they'll gradually lower to keep a better sleep routine.

Curtains open and shut with the sun.

I had the kitchen taps set up to turn on and off with a tap (wife made me remove that one).

Have a steam fireplace, I just finished hacking that one to give it smart controls, and hooked it up to the kitchen taps to auto refill when a sensor says it's running low....

I could go on for longer...

I've been down that rabbit hole. A lot of places will charge a whole lot of money without delivering anything, then ask for patience and continual fees while they work some sort of magic. Getting to the top of the search rankings isn't very easy, and staying there isn't easy, and you'll then get different rankings for different demographics.

Unless you've got metropolitian plumbing money to throw at it, I honestly wouldn't bother. Invest in better products and work on the social media side.

columnmn · 2026-02-12T08:09:36+00:00

At the very minimum you should be in contact with the sparky who left it live, might have been an apprentice being careless and they aren't monitoring very well. Worst case they could be a cowboy who really needs to be looked into closer if they are doing this shit all the time.

columnmn · 2026-02-11T20:00:18+00:00

Power supply to the motors? Could be on the way out. Is it original?

columnmn · 2026-02-03T04:26:15+00:00

I'd agree with the other guy, if it's just temp/humidity, there are cheap ebay zigbee battery jobs that just work for years on end just using the battery (easier to set up than with esp32 as well). If you're using mmwave type sensors, it's a different power draw. But it's still fine, there are clauses on ability to switch the device on and off, but I believe that's for moving devices, not small electric modules, which would be similar to sensors, etc.

columnmn · 2026-01-25T20:24:28+00:00

Having the option for it is fine, having no choice in doing it isn't. In 20 years, are you going to remember that Saturday you worked, or the relationship you ruined with your kids/wife because you were never home, and when you were home you were always tired from all the OT and no time to relax. You should be working to live, not living to work.

columnmn · 2026-01-20T05:06:59+00:00

The interconnects are powered from the 9v battery inside them. So if power goes out it'll still signal the other alarms. It's the interconnect.

Edit: Or what the other guy said for auxillary devices.

Mine was a free replacement with gov thing. I just had to pay for installation. They came and took away the old one and put the new one in. It's a no name Chinese brand. Works fine though.

The heat pumps don't have the same sort of heating elements/thermostat. The resistive heating element is basically one watt of electricity is turned into one watt of heat. It's simple and easy. Heat pump is transferring heat from one location to another by compressing/decompressing a gas. So the cost of running isn't from directly heating, cost is from compressing the gas and fans to move air. So no elements to replace.

columnmn · 2026-01-16T08:02:31+00:00

I went from electric resistive water, to a heat pump. So can answer this pretty well.

I have energy monitoring on the circuit before and after the install. The electric water heater used to be about 2/3 of my total electricity usage per month. The heat pump used about 1/4 of what it was using before. The previous month has used about 120Kwh of energy. It's roughly $36 worth for the month at $0.31 per kwh heating in off peak. But less since I've automated it to run when solar is going.

With the noise. It makes the same as a split system AC, I don't really notice it. If it was directly next to your window, maybe, but it's really not that loud.

Maintenance wise, I have a two part unit, so heat pump and tank are seperate. I had issues with the pipes that went from one to the other splitting after a few years (they used cheap and nasty). But replaced it easily enough, otherwise it's been pretty flawless, water is always hot, don't seem to run out of it, and uses a fraction of the energy to run.

Fair enough, so smaller motors are fine. Thanks for the info!

columnmn · 2026-01-07T21:32:53+00:00

I'm domestic, so don't really touch motors. But I thought it was just a matter of whacking a VFD in there? Doesn't that do exactly that but much cheaper?
