Playing with my cell phone camera trying to get some interesting photos. The quality isn't the best, but I like some of the perspectives...

I wrote a post about my understanding of Infrared Light and how it's useful.

I went on a quick overnighter in 20 degree weather. My pack weighed out at 17lbs including food and water. When I weighed it when I got home it was 13lbs. I had nearly 3.5lbs of electronics that much of had migrated to my coat pockets. My skin out weight was 26.4 lbs when I got home (no water, half the food eaten).

I tried several layers of space blanket type tech to keep warm. It did OK. Cold going to bed. Once I padded all the cold spots, it worked OK. I had to break out the hot-hands and shove them into my wool mittens and put those on my feet. It's odd getting out of the hammock at 1am to find your feet had thumbs!

The temp according to my new WeatherFlow Weather Meter was 21.7 degrees at 1:45 in the morning.

I took a pile of thermal images looking at how we keep warm and where heat leaks out. Nothing overly surprising. Cold spots tend to mean a greater temperature exposed to the environment where it radiates out and becomes visible to the camera.

My home made buff/neck scarf was a big win. I won't be backpacking without one of those as it just made my short list.

I tried out a LOT of new gear this trip. My clothes (except the new buff) and the rain fly where the only gear that has been on a prior trip. The big surprise was the ground cloth I made for my air mattress. It held the mattress in place in the hammock surprisingly well. So well, I will make another without the grommets as I don't think they are necessary and thus can cut some weight.

I recently picked up a Seek Thermal camera which plugs into my cell phone and allows me to see temperatures of stuff. It's a cheap unit, so it doesn't have the built in calibration tables that the expensive 'real' test equipment has. But it's good enough for most people's needs in a non-technical use.

I am reading all up on emissivity, and the science of how it works. Because this influences my usage of my laser cutter, and blacksmithing and even cooking and anything that relies on heat.

So I decided I am going to make a Mobile Science set. Mobile is dual usage, one, it's portable, two it's centered around my mobile phone.

My phone has a lot of sensors and capabilities already.

The Seek Thermal camera gives the phone another super power.

I also want to add a Consumer Physics SCiO https://www.consumerphysics.com/myscio/ which is a molecular identifier. I've wanted this thing since they ran it on kickstarter several years ago. I have actually seen it work in person and absolutely love what it can do. I think it will turn out to be a disruptive technology. This item will be the primary tool in my Mobile Science lab once I get one.

To compliment these two IR different sensors, I want an assortment of basic hand tools that will facilitate in preparing materials for the phone accessories.

I will be working with botany and geology. Also a bit of chemistry.

Optics is a pretty natural option too, given the camera on the phone. I will be making some bead lens microscope adapters for the cell phone camera. A spectrograph as well.

I also found a phone accessory weather sensor that I will be picking up.

I made up a cardboard tray on my laser cutter to organize the few bits I have gathered already. These are fitting in a waterproof cell phone case. I am looking for a waterproof tablet case.

My goal is to have a solid Science Lab the size of a Science textbook. I will likely carry this set about anywhere I go.

I am crazy excited about this idea.

Does anybody here use a Buff? (that neck scarf hat thing)

I've been looking at them, and just can't really spend $20-30 on something I am not sure I would like.

They seem like a nice multi-purpose item, right up there with a cotton bandanna. A lot of overlap in uses actually. Effectively a synthetic bandanna.

I've done some cold nights in the hammock (3f in my book) and keeping your face out of your sleeping bag so your breath doesn't dampen it can get cold on the cheeks.

I made a Buff at 3am this morning. I couldn't sleep. I had finally bought some fabric yesterday to make some gaiters (Dirtygirl gaiters style) and a matching buff. $1.97 for a yard of jerseyknit (maybe? stretchy in one way) poly-something. The labels aren't very good at Walmart. I've enough fabric for a couple of sets of both Buffs and Gaiters. That match!

It's an easy enough project. A few minutes on the sewing machine using the zig-zag stitch so the fabric can still stretch. I cut the fabric 18 inches square. Sew it up so it can stretch to get bigger around so it will stretch over your head.

I found that 18 inches around (minus sewing allowance) is maybe a tad tight for me. For sure I will be making the next one longer, as I can't double this and use it as a beanie over my big head. The 21 inches left over from the part I cut off the yard of fabric ought to be just about right.

I've been wearing it since I made it. I slept with it, but it somehow came off in the middle of the night (sleep undressing?). I've been wearing it all day. I usually don't like things around my neck, but it hasn't bothered me unless I think about it.

Just wondering if anybody has had any experience with the real thing. I would expect a seamless one would be significantly better than my hack-job.

Knowledge doesn't add any weight to your pack. So here is a look at how a camp stove heats up.

I just picked up a thermal camera and am starting to investigate the energies (thermodynamics, not Reiki) around my camping gear. Energy sources are heavy to carry around, so if I can maximize the utilization of what I do carry, I think I can have a more comfortable trip. I plan on looking at EVERYTHING. Cooking, clothing, shelters.

While I knew that shiny metals are heat reflective, and anodized metals are heat absorptive. It really doesn't sink in until you can see it and play with it.

Some of the cooking related things I want to test are different types of stoves, post cooking coozies, wind screens as part of the part warming process.

What else should I look into? What do you want to see? How should I format my tests so they are actually meaningful when read?

Anybody in the Chicago area (or passing through at any time) and want to take a look at YOUR gear?

I made some Mukluks... starting with duct tape of course, but than code!

These are 'house shoes' as they where just a test to see if I like them or not.

Source code can be found at https://github.com/creuzerm/openscad-projects/tree/master/laserable/Mukluks

I tried using my laser engraver to strip paint and mark the metal.

The paint stripping worked remarkably well.

I also tried using some dry moly lube as an engraving agent. This also works well. The laser can't touch metal, the metal acts like a mirror unless much more powerful than I have.

I wrote a bit of OpenScad to laser cut a leather pen case. https://github.com/creuzerm/openscad-projects/tree/master/laserable/Pen%20Case

I cut it and am looking at it and while it looks good, I think it is flawed.

The little round holes for stitching are easy to tell a robot to make. However, I am thinking that they actually overly weaken the seam.

I didn't look for the wisdom in the old fashioned hand tools.

The best stitching punches put little slits at a diagonal to the seam. I think this is actually very clever. This directs any tearing forces away from the next stitch hole and also not directly towards the edge.

So back to the drawing board so to speak and change the code to cut slits.

Than time to test and see if the slits really do make for a stronger seam.
