Very simple boot dryer unit

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

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!

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'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.

Big Clive

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?

The Peet version doesn't have a switch.

Big Clive

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

Big Clive

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.

Mike Page

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

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.

Mike Page

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.

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

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

Big Clive

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

Big Clive

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

Phil in the kitchen

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

Dom Wright

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?

Great item, ideal for warning boots come winter.

Mike Hughes

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