Water bottle carrier as the 'backpack'. * Water bottle * SOL 2 person space blanket * .7mil plastic sheeting * Airline wool blend blanket * Stainless camp cup * Mason cord * Rain coat
I quick overnighter to a place a buddy has access to. Crazy lightweight, but I know the area, so I know there are cattails nearby to make a sleeping mat. Rained much of the night, I stayed dry. Mosquitoes where the worst part.
The 10 mile walk in was good, if a bit warm. The 10 mile hike out was brutal. Got badly dehydrated. Water bottle is too small at 32 oz.
I tried making a water block for water cooling my MakerGear hot end this weekend.
I failed. kinda…
A bit of background as to WHY I would want to do such a project can be found at http://mike.creuzer.com/2013/01/watercooling-my-makergear-prusa-reprap.html I wanted to improve over the coil of copper being that I am about to re-install my 1.75mm hot end for a few lbs of plastic. Going to try ABS for the first time at this size. Not sure if I am going to have problems with that or not.
My fail is I was too lazy to go out into the cold to drill a hole on the drill press. I managed to salvage my stupid hole with a bit of tubing. Hopefully it doesn't cost me too much in efficiency.
I really have no idea what I am doing when it comes to using a lathe. Learning from YouTube is difficult as many of the videos posted are by people with as much experience as me (about 3 hours at this point).
Well, the next iteration should be better, right? I enjoyed making this enough I wouldn't mind making it again. But with a drill press. I think I will drill that hole first so I know it's right.
Using my UNiMAT lathe to fix my lousy hack saw cut and bring the aluminum block down to the right dimensions.
I turned down the black insulator a bit as I don’t have metric drill bits. The bigger tube is to couple airline tubing together on the OUTSIDE so I don’t get even more restrictions of water flow.
THERE I FIXED IT. I ran a bit of aquarium air hose through the buggered up hole. I am going to lose a lot of heat removal capability, but it lets me temporarily salvage this part. The water going through is in it’s mid 60s, so there is going to be a big difference, so it should pull heat well.
Until I make a new one.
I cut a piece of aluminium in half with a hack saw. The tray did a decent job of collecting the aluminum dust. Terrible surface finish on the cut. I did not do a good job of making the cut straight.
I tried drilling the hole using a hand drill because it’s COLD out in the garage where my drill press is.
I FAILED. I totally didn’t get things where they wanted to go. I’ve a hole on the inside, and a double hole on one end.
I can JUST snap the wooden clip in place with the water block installed. It’s going to be a royal pain to un-clip it.
The water block is small and light. It should work well I hope.
As promised, here are some more details on the construction of my Home Made CO2 Reactor. This CO2 Reactor is made from a couple of aquarium siphons, and an airline tubing splice connector.
I drilled a hole in the top Siphon Cap the same size as the airline tubing splice connector. I chose to drill the hole as close to the edge of the ridged plastic in hopes that I can give the connection some mechanical strength. I left as much room as I could so there would be enough surface area to make a watertight connection.
Here I am drilling a hole through the plastic siphon hose after I had slipped it back onto the end of the siphon cap. This hole is the same size as the inside of the plastic airline splice peice. I wanted the rubbery hose to form a tight seal around the airline splice.
After a lot of cleaning of the burs in the hose and pushing hard, I finally got the splice to fit inside the hole.
I made an improvised clamp system out of 3 nylon zip ties to hold this whole area toghether. This area leaked a little bit, so I ended up wrapping another zip tie around the elbow of the airline tubing and the siphon tube, to press the airline tubing more tightly against the rubbery hose in hopes of creating a better seal. The water leak seems to have stopped.
In looking at how the completed arrangement thing functions, I may move the airline tubing down into the larger part of the siphon tube. With the airline tubing fitting where it currently is in the hose, a lot of water preasure is trying to make the whole thing leak. I think by moving the airline fitting out of the hose, and into the larger tube, where there is mostly gas as opposed to moving water, I can eleminate the chance of this fitting creating a leak. I also think that I would be able be able to change out one of my Yeast & Sugar CO2 bottles without water trying to flow down the airline tubes when the whole thing is mounted higher then the water level on the fish tank.
I LOVE schooling fish. One of the reasons that I am into freshwater aquariums is because you can afford a school of fish.
Yesterday I went to 2 different pet stores. The second trip was to actually buy fish. I went for Cardinal Tetras, and bingo, they had them. They where pretty cheap too! $1.49 each or 4/$4.99. So I bought them up. I got 9 of them.
It took about 3 hours to get them into the tank. I had topped off the tank earlier in the day, and had filled it to almost overflowing. I let the bag float in the water for half an hour (I had to take a liitle bit of water out of the tank first, it was THAT full). Then the bag of fish got emptied into my water change bucket. A bit of airline tubing siphoned a bit of water out of the tank. Every 20 minutes or so, a little bit more water got siphoned into the bucket. After 3 hours, I had about a gallon of water in the bucket. I then netted the fish out of the bucket into my tank. This is about the most effective way I can come up with for adding fish to my tank. The fish get a slow change of water to adjust to, and no pet store water gets into my tank. I have also in the past added a drop of general cure-all type medicine to help keep the fish healthy – tetras are pretty lightweight, so I don’t do it to them. The cardinals picked up their color pretty quickly once they where in the tank. I try not to take photos of new fish the same day as I got them, their usually stressed and their color is off. The Cardinals are getting along famiously with my 3 Neons that I have already had for a while. The 12 of them are back and forth in the tank. A dozen schooling fish is so much fun to watch! The Angels are laying eggs YET AGAIN as I type this, so they have been pretty teritorial the last day or so, so they would run the school off if they felt a little crowded.
It is so interesting watching my tank now. With just the 3 Neons, there wasn’t much schooling going on in the tank. When I FIRST got the Neons, I had a half a dozen, and they didn’t school up all that much even then. It looks like somewhere between half a dozen and a dozen might be the number to half to get good schooling behavior. We will see how many of the Cardinals make it a week.
