Another knife created. This one is a ladies boot knife, and the 4th knife I have forged from steel made in my own shop. The scales are elk horn from the ranch.
And another older knife, this one using an old blade, with elk scales and a beaded elk sheath. I plan to forge a better blade, as I really like the sheath.
Yet still another knife. This one has an 80mm blade, which was copper plated and patinated prior to adding the handle. I was going for sort of a neolithic vibe.
It’s smaller, but it’s big enough for most things.
We’ve still got the old one, BTW. The issue is that the only local repairshop that deals with that brand decided to shut down for three months at Christmas, and my Dad got sick of waiting for them.
Time to start prepping bird houses. Good for house finches, chickadees, and wrens. The design is such that you can get three birdhouses out of a single 1x6x8’ plank, with minimal cuts and waste.
Clearance sale at the electronics store. $3 for a 3W mono amp and not bad tiny speaker. Unlike other scavenged amps, these don’t have a problem with ground-loop feedback when playing audio from the same Pi that powers it. The white ones have a Bluetooth setting. I don’t know if I’ll need that, but why not?
I’ve been lurking on this thread for quite a while, I enjoy seeing all the cool things you all have been working on!
Now, I thought I share something of my own & who knows, maybe someone will have feedback on my design .
So, I’ve been growing edible mushrooms as a hobby for a while now (mainly Lion’s Mane & Oyster) & I guess I basically just got curious to see how much biomass of mycelium I could grow in liquid media. This is done on a commercial scale to produce mycelium used in supplements, food products & for metabolites that can be used in drugs. To do this I will need to meet a few criteria, mainly: sterile, oxygenated, temperature controlled and of course balanced growing media. The one thing I haven’t pegged down is a high temperature resistant filter to be used on the air intake & output.
ETA: this whole assembly gets sterilized in a pressure cooker.
This project is still in early the stages but I have purchased or have most of the hardware & have ordered the Polycarbonate filament that will be used to 3D print the mixer / impeller.
Making some progress.
Found appropriate, reasonably priced filters for the job.
Also got a lot more of the components ready and did a little fabrication / assembly / fitment. Nothing is fixed in place yet. Test fit to the fermentation vessel are the thermowell, threaded rod to support the mixer, inlet & outlet for aeration & also a blank hole for the injection port (I neglected to include this in the 3D model)
Also assembled the mag-stir plate. I have not attached the magnets to the fan blades yet. I’m waiting until I finalize the impeller / mixer that goes in the jar so I can get good alignment between the two.
