Yeah I think this is it. On closer examination of the switch by the door it twists sideways when being switched, like the hinge is broken on one side, before clicking into its detent. Thanks.

If I jiggle it just right it works like a three-way should. I'll bring this up when I sign on to the lease (I've just moved in to a share house).

Tell them you think it's arcing, makes kind of a pop noise when you fiddle with it. I bet they replace it in 24-hours.

I love it when tenants make unauthorized "upgrades" to their unit then after demand some sort of compensation, that's a thing that actually happens according to landlords I've talked to. Like "Hey I put in a new fancy sink in the bathroom, here's my invoice I think we should go 50/50 because I added value to your unit"

Some landlords are fine with this sort of thing if you talk to them FIRST.

...And some will say they're fine with it, until you actually bring them a receipt.

It's one of those which you need to experience once clearly and only then you start to notice it all over. Try running a decent size Tesla coil indoors, that should do it.

Ozium is different than ozone. Although ozone has been used as a air cleaner.

Any kid who played with slot cars knows what ozone smells like. Hold the car just high enough that the current is arcing and sparking like crazy, and that smell is basically ozone.

Yeah, I bought my old van via internet auction and it smelled like an ashtray. A friend of mine had an ozone machine - we let it run in the van overnight and like 80% of the cig smell was gone. The remaining 20% faded over the next month or two :kiddo:

Pretty much any major deodorizing task, is really nice for cars since you can leave it there overnight enclosed.

Yeah just remember if you use it indoors, you need to ventilate before entering the space again.

OZONISERS (I just like how that looks) are nowadays sold as air purifiers to consumers a lot so you have people inhabiting buildings that have serious mold or other air problems and then they exacerbate that by running a machine that produces poison gas 24/7. Good times.

A Brisbane man spent 18 months collecting and wiring together thousands of discarded batteries to create his own "homebrew" version of a Tesla Powerwall, Elon Musk's home energy storage system, because he "was bored".

"[I needed something] to get my ideas out of my skull and onto the bench, so to speak," Pete Matthews told The Link.

The self-taught computer repairman now uses his backyard invention to power his family's off-grid household appliances, excluding his hot water, air conditioning and stove, which are still connected to the grid.

He says his invention can store 40kwh, or 2.8 times the capacity of Tesla's newest 14kwh Powerwall 2.

"My power bill came down from about $1,700 to around $400, so this is significant savings," he said.

Mr Mathews said his system cost him $10,000 and is made from 4,480 18650-type lithium-ion batteries, a generic battery, commonly found inside laptops and other rechargeable consumer devices.

The batteries, which are sold by the kilo by recycling companies, are about 8 cents each, while his other componentry was purchased on eBay.

"You buy stuff off the old interwebs and you solder it up and it actually works," he said.

After reading all that I was ready for some crappy construction but I was actually quite impressed?

You can also remove yellowing from old plastic computers by putting it in a bag full of ozone and leaving it outside (or under another UV light source).

Not "pop out", "pop", as in explode due to an internal short. Since, y'know, they're discarded batteries.

I was going to say “I’d only be comfortable with that if it were on a generous concrete pad with halon fire suppression”, but then I considered how I am comfortable parking cars, petrol or electric, in a garage attached to my house.

I would still review my insurance policy very carefully and keep a webcam pointed at the shed just in case.

Yeah. Brushed motors create small arcs many times per second.

If it's a brushed drill that seems likely, there is arcing between the carbon brushes and the motor. They actually have to carefully design all the plastic and other materials inside there to be UV resistant or the arcing destroys them in short order.

I could go into the safety aspects of this, but honestly the biggest issue is that he has tons of mixed cells (you can't really tell until the end of the video, since he puts similar cells on the exterior of the packs, presumably for cosmetic reasons). Using mismatched cells of vary ages means the individual cells might have very different full charge capacities and impedance during charge and discharge. Even he does everything safely, this will impose a bunch of restrictions on the overall capacity of the battery banks, as well as their overall efficiency.

Otherwise, it looks cool as hell.

In that same shot, it looks like he has an absolute assload of extra cells though. I'd imagine it'd be possible to test each cell and bundle them in groups that share similar charge/discharge/impedance characteristics?

Definitely it's possible! Cell manufacturers even do this themselves at the end of cell production---the cells are partially charged in parallel (I believe), and then sorted based on the estimated maximum capacity (and, at least for the Japanese cells, this means that they are graded from D-C-B-A-S rank--they might have "F" too, but they might also omit it for obvious reasons). They can sometimes charge very slightly more for the better cells, but mostly pack manufacturers want to build packs only using cells from the same lot and of the same grade. This helps ensure that they age more evenly and that a mismatch doesn't develop over time.
