DIY Wood Stove Fan for under $50 - All



They sit on top of a log burner and suck out heat from it and the pielter device generates electricity and runs the fan, which blows the hot air off the heatsinks.

That's not a real great one. I'd go for a larger bottom heatsink, fins up, and a vertical downwards blowing CPU heatsink.
The top heatsink has to be colder than the bottom one to generate power. (Pielter devise)

I like it. I think that using a brass or copper propeller would enhance the steampunk look.

Where do you find peltier devices in scrap?

They use Pelter's in electric chilly bins (Coolers in America?)
Often the plastic casings broken, or broken hinges.
I'm not really a fan of them, they use up too much power and flatten battery's and can only stop something from heating up a bit, like they won't cool or freeze anything, there might be good ones out there, but...

Some water chiller units for home or office, They run on mains power and have a good power supply, if it still works, its probably worth more to sell like that as 'project parts' on eBay. People use them for weird things. Cooling chips in computers etc.
If its power supply's not working, Pelter's have no real reason to stop working, the device will still be working. Easy to check though.

My mother-in law got me the Ecofan version of this for my woodstove. I use it more for a thermostat - when the fan starts to spin I know that the stove is getting good and hot. I does
not move too much air around though. I gave a friend of mine a few of those heat sinks to build the fans but I have not seen them yet. Maybe this fall he'll finish them.

Ooooohhh, nice boards, those little relays, spesh in telecom epuipment, have nice little Gold contacts.
I'm sure some are solid Gold too.

Thanks for that information. I never knew those little board mounted relays actually had gold in them. Couple years back, I scrapped 100's of those style boards. The local yard only gave me low grade prices for those type boards and I fell for it, thinking the only goodies on any boards were Tantalum Caps, IC Chips, MLCC's, or Gold Pins. I'll certainly be on the lookout for them from now on.

Posting this for Alloy2 to take a gander at. My uncle gave it to me about a year ago.

It has TUNGAR BULB CAT. 189048 stamped on the base.

Wow, US$85 on eBay.. NZ$117.... Nice find. It looks clean too so that should add value.

Not my usual ewaste but I couldn't pass it up. Thank goodness the tread had peeled off after what I assume was a blowout from a truck. I had a hard enough time loading the aluminum wheel and the remains of the tire. I cut the bead with a big pair of bolt cutters which freed the wheel. I'm not sure what it actually came off of but it's 23" in diameter and 15" wide.

I picked up an INTER-TEL AXXESS phone system last week and wanted to show everyone what's inside them in case you run across one.

This system was equipped for 128 digital stations, 16 analog stations and 72 trunk ports.

Here's a digital phone that came with the system above.

Inter-Tel 550.4500 Digital Phone.




These phones are easy to take apart even though each has 24 screws.
You get 1 good board and 3 more with gold plated contacts.

This is the voicemail from the Inter-Tel Axxess phone system above. It is an Inter-Tel Axxess Axxessory Talk OS2 Voicemail.
These are older voicemail systems from the mid 90's I believe. Large socket motherboard, 6.4 gig hard drive, full size cd-rom board and 4 gold finger boards.

This is an upcoming auction near me. Looks like some goodies in this batch. 2 different lots. 5 hours left on the auction and both lots are at $1. I'm sure that will increase in the last hour although I doubt it goes very high.

Thanks Mike.
I have about 8 of those VM cards with the solid state drives that I keep to sell or trade. The ones with the hard drives are scrapped. They've been out in the field for 16 to 18 years and most are on their last leg.
As far as the photos, I like to post pictures of the phone systems and data equipment I scrap. I have referenced this post several times while out in the field looking at boxes of phones to determine if I wanted them or not.
Some of these phones have only low grade boards and are not worth the trouble.

I've been busy in the garage today trying to get things under control again.
The first pic are some mother boards from some "all in ones". Not sure if that's the proper name for a monitor and pc built together. It's the first time I've scrapped any of these.
