I picked up a new 'backpack' this weekend

227 grams, without the two dinky water bottles it came with.

It's going to be challenging to get a 3 day trek into this itty bitty waist bag. Warm weather trips only.

My last weekend trek last fall, water became a problem, so this is probably a bit water-focused.

I am making 2 leather pouches for the Sawyer Squeeze Mini water filter and the cleaning syringe. One tucked into each side next to the water bottles. I cut the 'straw' down so it fits inside the back of the syringe handle. The squeeze bag fits inside the pack.

The kids are getting the half liter water bottles that came with this bag. I am replacing them with larger bottles. The silver bottle pictured will likely be my Berky Sports bottle once I find it. The green bottle in the black sleeve has a soup can it is nested with for a cook pot.

I am making a new 8.5' square tarp out of a window insulation kit. This will eat up the bulk of the pack. Cordage to pitch the tarp are 25' and 10 foot pieces of Amsteel Blue (silver colored) wrapped around the outside of the pack and held on with a soft shackle. Also will have several lengths of braided mason line.

Other items include:
A SOL 1-2 person space blanket or two for sleeping.
A disposable clear rain poncho in case it rains.
A bug head net.
2 citronella tea light candles.
My new LED headlamp with the 3d printed red lens.
A norwex towl (my wife can't stand the feeling of them).
A long sleeve polyester shirt.

I need to make a 'repair kit' with neosporin, tape, a needle and thread, a bit of wire and the like. Stuff to keep me and my gear walking.

Sticking it all on a scale at the moment, 1610g or 3.5 lbs.

What am I missing for packing out my new 'bag'?

My new waist bag. I like the color and that it can hold 2 water bottles. I have some amsteel rope wrapped around it. I am making a pair of leather pouches for holding the Sawyer Squeeze Mini water filter parts.

The leather pouch on the right side will be added and a mate to it on the other side.

I recently purchased an Ozark Trail LED Headlamp to replace one I left at my folk's…

I recently purchased an Ozark Trail LED Headlamp to replace one I left at my folk's place. I was hoping for a AA headlamp, but walmart doesn't sell those anymore, so I got the cheapest AAA one they had as it sported the longest battery life.

It doesn't have the features of the other lamps, like a red LED lamp.

So here is my attempt to fix this. Print the cover in something like Red Taulman T-Glase to create a red filter for this light. Attach it with a rubber band or some other method as deemed appropriate.

This particular model is Walmart SKU 1742701068

Length: 2.1 inch – 5.3cm Width: 1.6 inch – 4.1cm Depth: 1.3 inch – 3.3 cm Weight 1.5oz – 43g Weight with batteries: 2.8oz – 78g

High = 50 lumens for 15 hours at 20 meters range
Low = 10 lumens for 91 hours at 9 meters range

I've posted the printable files at https://github.com/creuzerm/openscad-projects/tree/master/OzarkTrail50LumenAAALEDHeadLamp in-case anybody else wanted to print a copy of the lens.

I recently purchased an Ozark Trail LED Headlamp to replace one I left at my folk’s place. I was hoping for a AA headlamp, but walmart doesn’t sell those anymore, so I got the cheapest AAA one they had as it sported the longest battery life.

A bit of time designing, and a bit of time printing with Red Taulman T-Glase

This is my favorite, but I am going to make it longer so the ‘fingers’ reach each other in back and can hook onto each other.

I now have a red lens cover for the headlamp.

Length: 2.1 inch – 5.3cm Width: 1.6 inch – 4.1cm Depth: 1.3 inch – 3.3 cm Weight 1.5oz – 43g Weight with batteries: 2.8oz – 78g

High = 50 lumens for 15 hours at 20 meters Low = 10 lumens for 91 hours at 9 meters

Three white LED bulbs, switch on top. Definitely NOT water proof like my missing one.

The red is so clear it’s hard to see the finished print on the printer.

A couple of different styles to attach, trying to see what I like best.

The elastic held better then the fingers, but it’s parts I can loose, and then what?

I am kicking around an idea for a cell phone based water sample spectrometer

It would be used for testing the water in my aquaponics system. I am not sure that the stuff I want to test is even detectable with the hardware I am going to use, but working out the mechanics is what’s challenging for me at the moment. The genisis for this idea is at http://www.backyardaquaponics.com/forum/viewtopic.php?f=50&t=11840&start=150#p345100

The process is to use the LED flash of a smartphone camera, a bit of a CDr or DVDr as a diffraction gradient, the camera, and the processing power on the phone. You measure distilled water, and then the sample and compare the two to see the differences.

The drawings are a quick render of the OpenScad file. The half-circle is a pivot that will hold the diffraction gradient so I can play with angles. I also need to add a spot for the test tube somewhere along the thin light slot.

The whole thing will be parametric, and customizable to any given smart phone.

Well, this is the plan. I am going to sleep on it a night, see what I dream up on it, and maybe send it to my printer tomorrow.

Moving my plant stand

With the changes in my life, come changes in where I can keep my furniture. I had put my plant stand in the sliding glass window, as I always kept the shades open. Now, it was deamed too annoying to fight closing and opening the blinds around the planter. It had to be moved.

Aquarium and plant stand  I moved the plant stand in front of the window in the extra bedroom – the ‘project room’. The 45 gallon tank got set up in there. You can see that it has LED lights on the tank. I think this works pretty well. It’s not very bright, but for around 20 watts, on a 4 foot long tank, it’s not to bad. I have 2 aluminum gutters sitting on top of the tank I think I will be setting them up for hydroponics/aquaponics. One will be a raft system, the other ebb and flow I think.
I think I can make an automatic fill/flush system where I fill the raft unit, let it overflow into a temporary tank, when the temporary tank fills full, it starts a siphon, which rapidly fills the ebb&flow unit. The ebb/flow system will then have the fill -> flush siphon built into it as well, so once it fills, it will rapidly drain. If I size and balance things right, it should just automatically work passivly on a single, continuously running pump.

Florescent and LED grow lights I am playing around with the different grow lights to augment what little natural light comes in my north window. I have tried the $10 stick florescent tubes from Walmart which don’t work so well and burn out bulbs like you wouldn’t believe. Then I put in a nice t12 florescent fixture that I really do like a lot. I am also playing with LED lighting as well. These plants are going to be set up to be watered out of the fish tank on an automatic timer. I had to move the tubing around to the other side and yet have to set it back up.

Florescent and LED grow lights The boxes the African Violets are sitting on are LED light boxes. I know, the red LED light box would probably help the violets flower better, but, I need to cast a little light into the taller section that the Aloe Vera are in, so I thought I would give it a try. It’s interesting to play around with this stuff at least.

LED aquarium light hood Here you can see my LED lit 45 gallon tank with a single Molly in the tank to cycle the tank. I think the Jack Dempsey will go into this tank, as she will like the lower light level from the LED lights. The Molly has been in the tank for 3 weeks to a month now. Patience is a virtue that is often overlooked in setting up aquariums. Many people buy a tank and the fish rush home, set everything up and wonder why all their many fish died in a day or two, keep buying lots of fish repeatedly and still wonder why the keep dieing.

4 foot LED light fixture for an aquarium..

I picked up a bunch of LED christmas lights on clearence this winter. I have been intending on using them for making a LED grow lights for my plants.
Well, I have been on an aquarium kick lately, so I decided to make a 4 foot LED aquarium light.
I ended up using 7 strands of LED lights, for 175 LED bulbs.

I started with a scrap piece of plywood.

Drilled 175 holes in it. I thought I was going to be able to put more bulbs in then I did.

And started sticking the bulbs through the holes.

You can see the light bar starting to come together. I took a photo as I added each light strand so I could see how bright it would get.

I zip tied the wires to the board to hold the hole mess together. It looks terrible, but it is what it is. I can always take it apart when I want to try something different.

The lights kinda go all willey nilley, but that’s ok I guess.
