BBQ blower v4

Somehow this project is never ending for me. Just 4 years ago I made a third version of it and it helped a lot, even though it was ugly inside and not powerful at all, but I didn’t think of making a new one because it was enough. But just the other day I was disassembling an old server and inside it there was two powerful centrifugal fans (12V 1.85A, ~25W) and thought I make an upgrade with one of these…

And this time I also wanted to have a metal pipe, not PVC. The fan is 12V, so a larger battery is needed, I made it using a spot-welder after assembling all the parts I needed.

BBQ blower v3

This is my third attempt at making my life easier with maintaining a fire. I wrote about other attempts here and here and it looks like that this project has a never ending continuity, since it’s such a useful device…

This device (like previous ones) are to ensure I keep my eyes out of smoke and lungs in proper working condition and this version design was inspired by other devices that are for sale on Amazon or eBay, but they are chinese made tools and require batteries to work… I thought I could make it a bit better with rechargeable batteries, a small display to see how much power is left, a normal on-off switch and possibly with a better air volume output. Also as an added bonus I thought I could use it to inflate a mattress a bit, so that I don’t have to do it with my mouth and then sit down a bit being dizzy AF. Obviously this doesn’t create enough pressure to inflate it all the way though.

I remember a scene in a “Tom and Jerry” cartoon episode “Barbecue brawl” where spike was blowing into charcoal to get the fire going and of course that didn’t go well, if only he had this device though :D
