October DODOCase Build Night at CC Makerspace

This week at the Chesterfield County Makerspace, we were lucky enough to host a DODO Case Instructables build night.  During the week beforehand, Doc and I sat around and brainstormed some ideas for case modifications that would help make the cases better.  We determined that a head strap is mandatory to enjoy any virtual reality games that require a controller. At the RVA Makerfest, we learned that we need a way to be able to clean the faceplate from the hundreds of people that we cycled through our DODOcase, so I designed the front faceplate to be 3D  printed.  In addition to 3D printing the faceplate, I also designed a nosepiece.  I found out, from hard experience, that the cardboard is very uncomfortable for wearing any longer than five minutes; we have access to ninjaflex filament here, so I knew a fix would be fairly easy.  Here are the separate instructables for our mods: Faceplate Nosepad Headstrap Over the course of the night we led two separate groups of kids in constructing their own cases.  We printed out enough nosepieces that everyone could use one, and had enough elastic strap for people to be able to had head straps to their goggles.  Once everybody got their goggles assembled, hilarity ensued as some of the kids almost walked into walls while enjoying their virtual environments.  A few problems we noticed:  not a lot of VR apps for apple devices, some devices do not cooperate with the magnetic switch (although the DODOCase V 1.2 fixes this), and some devices were too small even for the braces to hold them in.  However, everyone had a good time and we cannot wait for our next build session.  Thank you Instructables for allowing us to put on this event.

Using TEC chips and heatsinks for personal cooling - heating collars or pads

I've been toying with using TEC chips (facinating devices that are cheap - applying voltage make one side hot - the other cold, Inversely, appling any existing temprature differential to the sinks PRODUCES POWER). They are used most commonly by consumers in auto beverage coolers and heaters. It  started when a car ran me down on my bike, and I was wearing a neck brace for months. I thought about how misserable I'd be if it were summertime. I also thought of those poor people that always wore them... Anyway, there's a thousand different easy ways to do this - I took fluid-filled plastic sections of a beverage cooler and attached them to a belt, which hangs around my neck. applied the heat  sink of the TEC and there you go - just wrap it in something. Now if I were on a motorcycle in summer and stopped in traffic, the cool collar would be a lifesaver, as well as a myriad of other apps. I cannot figure out the best (inexpensive) way to control this. It's easy enough to turn on and off - you can hardly forget it! But if I allow the chip to get too much wattage it will get too hot and self-destruct. Also, if I limit the wattage correctly, it would just need adjusting, and could be left on most of the time. The idea here is there are many ways to do this but they are too expensive... I want everyone to be able to afford it. If you use a Pot or resistor, the excess goes to heat and ruins battery life, and other controllers of DC current are expensive. Any help? I am almost 60 and have earned the nickname Misc. Expert among my family and friends, and I must say I'm very impressed with what y'all do here in this newsletter - Congrats!

What profile of pole would be torsionally rigid? Answered

Calling all mechanical engineers and physicists. I want to make a pole that can resist twisting forces. The application is a down tube on a bicycle frame. And I want to use bamboo because it's light, very strong, very cheap, and biodegradable. The problem with bamboo is it lacks torsional rigidity because its fibers only run lengthwise. I was thinking of wrapping a bamboo pole with a composite fiber (hemp and glue) at a 45 degree angle like they do with carbon fiber poles but maybe a different shape would be better. Can anyone think of a specific geometry of pole that is tortionally stiff? I noticed some bicycles have a triangular down tube. Maybe if I cut bamboo into three strips and glued them together into a tube with a triangular cross section, this might be less twisty. Am I thinking along the right lines here? My first bamboo bike has a lot of twist and this might be one way to make it stronger. Please let me know what you think. UPDATE: The issue was many fold. The short answer is Tonkin Bamboo is the species to use for bikes. This is what most people seem to use. Also Boo Bikes use dendrocalamus strictus (aka Iron Bamboo). My frame had some cracks possibly due to harvesting at the wrong season. I've recently gained more cracks and the bike flexes even more. It flexes like a noodle but I can still do an endo no problem. Go figure. Also hemp sounds like it gets more stretchy after being flexed about 1000 times whereas carbon fiber stays stiff. And squishy wood glue is probably not as stiff as epoxy. All this adds up to a flexy frame. My next one will be tonkin bamboo but I will try hemp and non-toxic wood glue again. UPDATE #2: I'm making a three wheeler and my engineering design teacher gave me some advice involving spaceframes and triangles. The plan thus far looks like this upright tadpole trike: UPDATE #3: I think I've got it! Instructables sent me a box of K'nex and I built up a model of a standard bike's frame. The thing is, when a bike frame twists, the opposing corners of the trapezoidal shape come closer or further apart. So a deep X brace from corner to corner seems to fix most of the problem. I'll try to post a youtube vid of what I mean soon.

Core Wars: The battle of the programmers.

Okay, brace yourself for a lengthy background story: In the 1960's and 70's, computers were much too expensive for a normal person to have one all to themselves. Before the invention of the Personal Computer (PC), computer systems were mainly employed in large universities, able to be used by students. However, there came a danger with all this: Back then, there was no such thing as protected memory, meaning that someone with minor hacking skills and some knowledge of assembly could easily wreak havoc on other people's data and programs. One such urban legend is that of a major business firm's main computer system, which a mischievous employee had installed his own assembly program called creeper, who's only purpose was to create copies of itself whenever it was run. This soon became a problem, as the creeper virus began eating up precious space in the memory and began corrupting other people's data and programs. After a while, another more brightly-hatted programmer created a program called reaper, which would make numerous copies of itself and destroy any creeper virii it could find and then self-destruct. Soon enough, things were back to normal. After hearing this story, a programmer named A.K. Dewdney got the idea for a game which he called "Core Wars". In this game, people would write computer programs called "warriors" in an assembly language called Redcode. Redcode had instructions not out of the ordinary of any assembly language. These programs were then run simultaneously in a simulated computer called MARS. The aim of the game was to make the opposing program crash by forcing it to execute an illegal command in the computer's shared memory. The surviving program was declared the winner. The absolute simplest warrior was called imp, and was written by Dewdney: MOV 0, 1 The MOV command moves copies a command from one place to another, in a position relative to the MOV command. Because of this, the imp would fill up the entire memory with MOV commands in a relatively short amount of time. Because the memory loops around (So, if the size of the memory is 8000 commands, then command 8001 would be executed as command 0) then it meant imp would always hit it's target eventually if it wasn't hit first. Another program which was written by Dewdney is called Dwarf: bomb      DAT 0,0 Dwarf     ADD #4,-1                 MOV bomb,@bomb                JMP Dwarf End Dwarf This is the first example of a "bomber" program. This program would drop DAT 0,0 (An illegal command) at every fourth slot in the memory in the hopes that the other program would accidentally execute it (cookie if you can figure out how it works). There are far other types of examples, like scanners, which try to scan the commands around it to see if they are illegal. Some programs can even repair themselves mid-battle. So, does anyone else still partake in this ancient game? I recently just got into it, writing my first warrior program a few days ago. Have no idea if it works, but it sounds pretty cool. It's based off of Dewdneys Dwarf but with a few modifications (I named it MindSplitter): bomb      SPL 1                 JMP -1                 DAT 0,0 Split        ADD #5,-1                 MOV bomb,@bomb                JMP Split End Split First off, this plants bombs at every fifth command instead of fourth, which I hope will help it spread out. Second, the bomb it uses is my personal invention that I call the Splitter bomb. In Redcode, the SPL command will jump execution to the specified command, while at the same time continue executing the commands after it. The idea is that the SPL will split to the jump command while the normal execution goes to the jump command, and both of them jump back to the SPL, therefore filling up all of the enemy programs processes. If the enemy program somehow manages to escape the loop, there is a deadly DAT after it. I haven't tried this out yet and I'm not sure how it would do in battle. If someone with a MARS emulator and a warrior of their own would like to put it to the test, I'd would absolutely love to hear how it turns out :).

What would be the VERY BEST way for me to TRANSITION into my newly adopted off-grid, survivalist, subsistence lifestyle? Answered

A 16'x16'x16', 256-square foot, A-frame cabin on an elevated 3' concrete paver floating DekBlock foundation with a 3'x 6'8" front flush door, one rear 48"x 48"horizontal slider window, and another upper 24"x 24" horizontal slider window for the sleeping loft.I'm thinking that one of those standard U.S. Stove designs might provide just a little too much heat for my needs up in the Copper River Basin region of ALASKA's rural backcountry. Who knows? What are your suggestions for the above described "habitat"? Where can I find the best deals for my 256-square foot space? (Heating/ventilation-wise, we're speaking of subzero temperatures and heavy snowfall, so, I don't believe that "opening a window" is a practical solution for me if it gets too hot and smokey inside my A-frame.) Plus, I've done the HEATING ESTIMATE for the A-frame I'm going to build and the numbers come out to about a 620,000 btuh (heat loss) for the new dimensions I'm finally settling on: 16'x16'x16' or 256sq.ft. This calculation is for -50 degrees F with cold floor, ceiling, and glass surfaces taken into account. (Insulation isn't a factor this early in the design.) "Wow!" I thought at first. "A 620,000 btuh HEAT LOSS! I reckon you can never have too much stove even for an A-frame design." (Being that A-frame cabins retain heat so well, and that my sleeping loft may get really HOT in the Winter, this was a preliminary concern.) Foundation:(4) 8"- diameter cardboard cylindrical concrete forms for pin-point piers;(4) 84" reinforcement rods for pin-point concrete forms;(16) Bricks for base of footing;(24) Layout stakes;(8) 5' batter boards;(1) Spool of wire for joining the two 14" reinforcement rods for each footing base;(1) Spool of line for marking building layout lines;(?) Bags of cement;(?) Bags of gravel;(?) Bags of sand...*A few questions about the amount of concrete needed for the four footings and the four concrete piers: "How much concrete will be needed for four 8"-deep concrete footings poured into four 16"-diameter, 44"-deep holes with each containing four bricks and the four reinforcement rod supports? How much concrete will be needed to fill four 8"-diameter pin-point concrete pier forms to an estimated height of about 80"-inches? How many total bags of cement, gravel and sand (aggregate) will my foundation require? Most importantly, how much will it all cost?"A-Frame Structural Triangle (Theoretical Dimensions):Sides = 16'Base = 16'Angles opposite sides = 60 degreesAngle opposite base = 60 degreesArea = 110.85125168441 sq. ft.Perimeter = 48 ft.Framing:(2) 2"x 10"x 16' girders;(12) 2"x 6"x 12' rafters;(6) 2"x 6"x 8' joists;(4) 2"x 4"x 4' collar beams;(10) 4'x 4' plywood sheets for subflooring;(2) 16' framing braces for structural support against wind damage;(?) 3200-square feet of roof/wall sheathing material for exterior surface areas...*A few questions about the amount of roof/wall sheathing material needed to cover the 3200-square foot exterior surface area: "How much exterior sheathing will I need? How much will it cost? I understand that metal sheathing is preferred in the Copper River Basin region for its snow-shedding ability, so, given everything I've just said, what are my options for the A-frame I recently designed?"My total approach to this whole subsistence lifestyle (i.e. living off the land within a small, confined space) is probably all wrong. I understand that I might need to change my complete "mindset" and adopt a sort of NAUTICAL (or MARITIME) theme with my decor, furnishings and appliances.Since I'm really getting into boats anyway (my one chosen option for escaping the bitterly harsh winters of ALASKA's COPPER RIVER BASIN if all else fails), I feel that marine stoves, composting toilets, and an overall nautical aspect in the "finish work" might help me cope since sailboat cabins tend to be tiny, and I may need to transplant a lot of what I have to my seagoing vessel, "Vera Essie".www.geocities.com/wduncanbinns
