Very simple boot dryer unit (Patreon)

Although this unit claims to be "the original", it is very similar to an American made unit called a Peet boot dryer.

It's worth mentioning that Peet don't seem to make these for other voltages than 110/120V.

The construction is inspirationally simple, and relies on hot air convection at low level to slowly dry footwear without damaging it.  It is intended to dry boots overnight if they are very wet and have them gently heated for putting on in the morning.

I've always wanted to explore one of the classic American Peet boot dryers, but they never seemed to do a version for 220-240V countries. While having a random browse for similar items I came across a single eBay listing for just one item and bought it to explore. The box came in a brown paper Amazon bag, but when I searched for the item it was shown as not being available. It's interesting that this unit claims to be "the original". So which came first? The American-made Peet unit or this one? The Peet-style units are quite neat in that they rely purely on warm air convection to warm boots or shoes and carry the humid air out. As such they are silent, but much slower than forced air versions. However, this also has the advantage of not overheating the footwear and damaging it. The heater assembly is refreshingly simple with most of the structure being an aluminium shroud to protect the plastic pipes from heat damage. At the base a metal pin passes through holes in the aluminium shroud and then goes into a groove at each side and is locked in place by fins on the plastic cover. I'd guess that the heater assembly and plastic boot supports have evolved with time. Supporting the channel with a dollar or two on Patreon helps keep it independent of YouTube's quirks, avoids intrusive mid-video adverts, gives early access, bonus footage and regular quiet Patreon live streams. https://www.patreon.com/bigclive #ElectronicsCreators

Wow I always thought those had a small fan. That design is way more durable than a fan.

Great item, ideal for warning boots come winter.

Am I understanding it right: The ceramic resistor dissipates the resistance as heat, and that's it? If in series, it'd be 240 V on 1400 Ω, so A is 240/1400 and W is 240/1400*240 ≈ 41 W in total. Is that it?

Ironic. I watched this vid, then another old one which was followed by an Ad for a "super efficient new technology heater!" Ha ha!

I'm sorry, but it looks like an updated model from Wallace & Gromit "The Wrong Trousers"

That's it. The simplest and cheapest way to get a suitable low power heater.

It does look a bit home-made. The original prototype was probably made from random plumbing parts.

I've been using a boot dryer for years, although it's the fan type.

I've got two 40mm PC fans (12V running on 5v) that I drop into each boot vaguely pointing at the toes and that gets the job done overnight by just circulating the air about a bit.

What an interesting video! I had no idea such things existed. Makes sense. Still on the subject of shoes / boots, I've often wondered what would be involved in an automated dog shit remover. Because nobody enjoys that job.

Get a cat, they hide their shit in the kiddies sandbox or Clives garden.

You can't go far wrong with those ceramic resistors. They fuse safe leaving something like a 2kV gap. Running them close to rated, the spacers and reflectors are a good call. The whole assembly might look simple but it's very economical and effective. Maybe if you managed to drip melting snow on the switch then touch it ... that's the weakest part I can think of.

I fear that any device that attempted to remove dog shit would probably end up spraying it everywhere with brushes and water jets.

Yes, that's the challenge. A conformable seal. If there was a better way ... I've been known to leave shoes for a month until it dries out. Would ultrasound be any cop?

I'm not sure how ultrasound could work here. I guess it's back to a twig and jug of water to wash the bits off.

The desiccant dryers are VERY fussy about their airflow being restricted. It can cause them to cut out on safety limits or throw error codes about airpath problems. That probably stems from people putting garments over them to try and dry them quickly.

I've got a similar set, except these are a lot smaller. They're a shoe insert that is able to dry boots or shoes and it takes up a lot less space than the tall tower one in the video. They've saved quite a few shoes in our household from becoming irreparably damaged from mildew setting in. The idea behind them is laughably simple, but they really do work!

I work at a National Park and they're widespread amongst the rangers and conservation officers.
