The blue-LED fan I have in my ZFS on Linux NAS is a bit louder than the other fans that I’ve been hoping for. I am going to replace it with a 600rpm fan.
You will notice that I have drilled extra ventilation into the top case panel.
Notice the clear-plastic fan. It is held in with zip ties.
Zip tied those SAS cables to tidy them up.
See the 140mm low profile fan on the cpu? Pretty quiet. 120mm 600 rpm exit fan.
Let’s snip some zippies!
Getting the fan power connected is always a chore. My fingers are almost too big.
Fan is now attached and power cables are managed well enough.
Trim it up.
Plenty of inlet.
Now I put it up on it’s shelf and get it plugged in.
and there’s a power switch at the farthest point back there.
Alright. Powered up and out of the way.
I saw this in a maker book and I must say that the editing of the book was deplorable. It was edited for brevity and not for guidance. This will need a complete rebuild to actually work.
How did I make this lid?
I lose lids off of travel mugs frequently. The great shame of travel mugs is the cheap caps that just fly off, into traffic, when biking. For a while I had been using lids from other disposable coffee cups. But then I found a lid to an empty peanut butter jar. So, pop quiz: how did I make this bad boy by spending no money on it?
I tacked the inner tube strips on to the copper pipe and chain stay with electrical tape. This keeps the assembly in place while tightening the hose clamps on.
I really like the idea of the Burley Travoy, which is a much refined version of the concept of pulling something like a (Whitmore) wire utility cart–the kinda cart that “grandmas” do their shopping with.
Well…i’m not a grandma, and I don’t ride a fasionable bike, either. So, when packing a pile of canvas sacks around a farmers market, as they fill up, I really want to put them in a stroller because the do get heavy, and commuting back to the bike stand after every visit to a booth is something of a time waster. This is a good opportunity for such a wire cart. I suspect the price of a wire cart is much lower than a Travoy.
Possible cons to towing one of these wire utility carts is bouncing and rattling. The wheels on these carts are so bitty I don’t see how you could safely tow them at a speed over about 10mph. I wonder if it would be possible to put some 12in kids wheels on such a cart and extend the front legs with some tin cans.
The only other bit of engineering is coming up with a hitch. For a short bike (not a long tail), a horizontal pipe mounted to the seat-post…something like this I’ve seen advertised as a kid’s wagon, or golf bag caddy towing hitch. I bet about 20in long segment of 2in dia of PVC would be a good starting point.
Is this crazy? Let me know how many wheels I’m re-inventing.
I was reading Ken Kifer’s article on building your own panniers, and he had a good suggestion on a DIY front pack: the bottom half of a small office waste bin. You can get kits to adapt handlebar brackets to baskets, you would apply one of them. The benefits include it being rigid, being brightly colored, and waterproof. The challenge is that you need to improvise a lid, and you probably wouldn’t get the benefit of a map window on top. However, cutting up a clear 2L soda bottle might give you a map window, come to think of it.
But what would make a clever lid? Huh–the rotating flap of a kitchen waste bin of course [forehead+palm=thwap!]
I’ve never seen a bamboo bike before! This is really RAD.
