A House Finch suffering from Finch Eye Disease prompted me to sterilize our feeder, which meant providing a temporary feeder to keep the birds flying. Having an abundance of lids from six gallon plastic cans / buckets, this made sense:
Which required an adapter betwixt pole and lid:
Which requires a bit of solid modeling:
The lids have a central boss, presumably for stiffening, so the model includes a suitable recess:
As usual, automatically generated support fills the entire recess, so I designed a minimal support structure into the model and cracked it out with very little effort:
The tangle off to the right comes from a bridge layer with a hole in the middle, which never works well even with support:
Didn’t bother the birds in the least, though, so it’s all good.
I loves me my 3D printer …
The OpenSCAD source code as a GitHub Gist:
A sterling knife followed me home after a Thanksgiving gathering:
The original cement, dating back to the middle of the last century, turned into friable dust around the blade tang:
I cleaned it out as best I could, buttered JB Quik epoxy around the tang and into the socket, joined the two, and let it cure in the natural position:
The rest of the knives in the set may need similar attention, but I’m not looking for trouble.
As part of converting the halogen desk lamp to LEDs, I replaced the hulking iron transformer with a flatter counterweight:
Under normal circumstances, you’d use something like steel or lead sheets, but Tiny Bandsaw™ can’t cut any appreciable thickness of steel and I gave away my entire lead stockpile, so I sawed disks from a pile of non-stick pancake griddles and drilled suitable mounting holes:
Another disk (from a formal aluminum sheet!) goes into the lamp head, with a trio of 3W COB LEDs epoxied in place:
The other side of the disk sports a heatsink harvested from a PC, also epoxied in place:
Realizing the head required only a little filing to accommodate the heatsink sealed both their fates.
A test firing showed the heatsink needed more airflow, which didn’t come as much of a surprise, so I milled slots in the lamp head:
Deburring the holes, blackening the sides with a Sharpie, and tucking a bit of black window screen behind the opening made the vents look entirely professional.
The small dome in the base originally cleared the transformer and now holds the entire 10 W LED driver, along with all the wiring, atop the counterweight sheets:
A cork pad covers the base for a bit of non-skid action:
I couldn’t convince myself filling in those sectors would improve anything, so I didn’t.
And then It Just Worked:
All without a trace of solid modeling or G-Code …
Our Compact Edition of the OED doesn’t get much use these days, but Mary needed a magnifier for a class on quilt judging and the OED has one that seemed just about right:
The magnifier comes in a removable box fitted neatly into the drawer, revealing a surprise underneath:
A detail view:
It’s a plastic ant from a bag in the Kiddie Surplus box my Shop Assistant grew up with and a pleasant reminder of long-ago days, carefully placed where only I’d ever see it.
Of course, it’s still there …
The ancient (Came With The House™) Electrolux canister vacuum cleaner long ago lost the plastic bushing around the opening passing its retractable cord, which I’d long sworn to replace. A recent trip around the Basement Laboratory paused near the recently relocated Box o’ Wire Loom & Braid, whereupon I snipped off a few inches of split loom and tucked it in place:
Looks and works better than before, anyhow.
The blue flap dangling off the back should latch over the exhaust port, but failed long ago when the latch tab eroded. I attempted a repair, which never worked quite right, and won’t get around to attempting another for quite a while.
Plugging a 64 GB USB stick with directories full of MP3 / OGG files into an always-on Raspberry Pi running Pi-Hole, one can use Icecast to stream them for clients on the LAN, so as to avoid over-the-Intertubes streaming issues.
The only changes in the
/etc/icecast2/icecast.xml file cover passwords, the number of source streams, and the
hostname. It’s that simple, really.
Given a directory of files, generate a file-per-line playlist:
find /mnt/music/goodmusic/ -name \*mp3 | sort > /mnt/music/goodmusic/playlist.m3u
Then set up a corresponding Ezstream XML file, perhaps imaginatively named
<ezstream> <url>http://localhost:8000/goodmusic</url> <sourcepassword>make-up-your-own</sourcepassword> <format>MP3</format> <filename>/mnt/music/goodmusic/playlist.m3u</filename> <shuffle>1</shuffle> <stream_once>0</stream_once> <svrinfoname>Good Music</svrinfoname> <svrinfourl>pihole.local</svrinfourl> <svrinfogenre>Good Music Streaming 24x7</svrinfogenre> <svrinfodescription>Techno Dub</svrinfodescription> <svrinfobitrate>128</svrinfobitrate> <svrinfochannels>2</svrinfochannels> <svrinfosamplerate>44100</svrinfosamplerate> <svrinfopublic>1</svrinfopublic> </ezstream>
Fire off the source stream in
ezstream -c /home/pi/Icecast/goodmusic.xml &
The ampersand tells Bash to fire-and-forget the process, so it runs all the time. One could, I suppose, put it in
crontab to start after each boot or puzzle out the corresponding
systemd incantation, but …
Add the station to your streaming media player:
'KEY_KP5' : ['Good Music',False,['mplayer','-playlist','http://192.168.1.2:8000/goodmusic.m3u']],
And then It Just Works™.
At some point in its history, the left rail holding the wood perch on our industrial-strength “squirrel proof” seed feeder took a hit, most likely from being dropped:
I finally got a Round Tuit and un-bent the poor thing:
Because the bend happened at the base of the vertical strut holding the shutter, I clamped a Genuine Vise-Grip sheet metal pliers along the straight section. The Craftsman knock-off Vise-Grip then applied torque at the bend, rather than just making things worse, and some two-axis tweakage lined up the rail pretty well.
With the bend taken care of, I clamped the rail in the bench vise with some scrap wood around the strut:
A percussive adjustment jam session flattened the top flange, leaving both sections as flat as they’re gonna get.
While I was at it, I turned a pair of stepped aluminum washers for the new wood rod:
Which looked about like you’d expect, including a little chatter from the cut off tool:
Yeah, I drilled the wood rod on the lathe, too; I loves me some simple lathe action.
Reassemble in reverse order and it’s all good:
We’re supposed to bleach the feeder every week to kill off the bacteria causing House Finch Eye Disease and, while I can’t promise a weekly schedule, we’ll (try to) reduce the amount of crud on the feeder this year.
