    PVC Fence

    Thinking a coat of UV stabilized professional polyurethane paint will help with the longevity of this build unless the PVC pipe is made already with the UV stabilizers for outdoor use. There are also decorative tops/finial that can be made with a 3D printer, molds, plastic/wood and purchased. For some reason Google isn't pulling much up for tops/finials other than these examples:https://www.etsy.com/listing/609171208/skull-fence-finial-for-pvc-pipe-resinhttps://www.etsy.com/listing/623279291/mid-evil-pvc-fence-finialhttps://www.etsy.com/listing/184661624/four-sided-spire-finial-spear

    How to Make Concrete Stacked Stones

    You can add colorants like powder dyes to the face of the mold's individual stones also to have different colored "stone" facades. These can be found at places like https://www.walttools.com/ under color products. I've also made molds using stones, with Dawn Dish Soap as a resist applied first, before using Type 2 Silicone that came out not bad when thinned with mineral spirits if either you make sure to apply only a 1/8" or less first coat or wait longer before removing the cured silicone. Typically, you want to use a catalyst vulcanizing silicone or polyurethane/urea made specifically for making molds or use latex in multiple layers.

    You can also start off with White Portland Cement and make your own cement mix with white sand and crushed lime or gravel. Then add colorants to suit desired end result. This will take some practice unless you consult with someone familiar with the materials being used. I've seen some use perlite and even ground up styrofoam instead of gravel also for a lighter end product material. I'd be sure to seal the later two products (perlite/foam) with something to waterproof or at least water repel. Thanks for sharing! I actually need the motivation on this project as I made and invested in molds over the winter to do similar work like you're doing though a little larger in house brick or larger size.

  • DIY Microwave Kiln | Fuse Glass in Your Microwave

    Way to go! Nice work and very inspirational. I never thought about using a microwave to burn out wax or PLA for use in the lost material method of casting. I used a stock microwave a little during my first undergraduate degree research to observe the different effect in catalyzing the classical reactions I was focusing on. Interesting application. Thanks for sharing!

  • Make Your Own *Really* Cheap Interferometer

    FYI... Youtube just suggested this video that goes into more details of the LIGO system, so I figured I'd share here too:https://www.youtube.com/watch?v=jtp71NT0GNg

    If I understand correctly, with a Lock-In Amplifier and the Differential Pre-Amp or Amp, the system can be improved to be even more sensitive when tuned optimally. Basically, upgrading the CIA laser or other frequency microphone/RF listening systems to be even more sensitive.

    GPS and the Raspberry Pi

    Nice design. I was wondering what there is on the market and open source also for interfacing the Pi's to the Arduino. I ordered the components to make a Breadshield, https://www.crowdsupply.com/loser/breadshield,so I don't have to wait until July to start playing with and was thinking to make similar for the Atomic Pi. While at it with extra connectors and perf board ordered (I even just ordered some Keyestudios Arduino shield prototype boards) I had a similar vision to make an interface from the Atomic Pi to Arduino and looks like has been done already very clearly.

    Neat to see a survival requirement implement made from Whirlpool boxes/packaging material. Awesome! Wondering if something like white silicone roof covering or maybe tar painted white would help with waterproofing and be more durable and easier to make for a roof coating. Wouldn't be cheap... though the closed cell spray foam spray lined on the roof and roof rafters interior would be another easy way to waterproof and make more rigid also so will last longer. Maybe strips of vines, bamboo or wood weaved before the cardboard roof is put on will improve strength more in this manner or without foam method.

    Neat, you've found natural kitty litter as a clay source also. The bags of the different types of bentonite aren't really that expensive... until like I realized in my situation there wasn't any local sources for sale and the shipping was well over 10 times as expensive.

The "Switchable DC Motor Linear Actuator Wireless Remote Forward Reverse" and the "Linear Actuator 20" inch Stroke Heavy Duty 12 Volt DC 200 Pound Max Lift 12V" are what I am looking at investing in for the truck cap. Probably will go with a 30"+ for the four corners of the cap. Then add square tubing for the legs stability and maybe bearing/bushing/lining material if you wanted to for a more rigid build. That material can probably be salvaged for free from treadmills, exercise equipment or even cost effectively from a salvage yard. We have the Boneyard here and other cities have similar from what I've found in my travels. Desks can be found for free online in my experience, i.e. Craigslist, Offerup, Letgo or cost effectively at the Goodwill or University Surplus Stores.Neat inspiration! Great Instructable.

I'm thinking sticking with the aluminum cap material since I picked up another cap for free that I took apart for materials and don't need as heavy a load on top where at most I'm keeping the rack for loading above the solar panel if I need to haul longer materials. The plan is to keep the tailgate swing out, at least the bottom, to be the steel frame to be safe. I picked up a Millermatic 141 for this project (I have new or salvaged body panels to replace also)... how do you like the 200?

    Will do. I was almost thinking about buying a hardness tester also... then I saw how much they are. Will have to find where I can use one. Might do some load testing also just to see failure potential... if does fail... since looks like I have enough material for two at least. The pivot point construct and material on the Air Walker was what first got my attention.

When I worked on the FT-NIR system and other alternative technology materials test systems I stumbled upon NIR helmets being used with methods in equivalent or less than equivalent to traditional MRI ways. There's not much info out in the World noting... though enough to "wow" many into creative insight into potential applications. That leads me into NIR methods like the Open Water Company envisions, though I don't recall work on polygraphs being pursued, for treating and diagnosing health conditions. These systems are like say a fingerprint analysis test tool. Yeah... a fingerprint analysis test tool doesn't tell us much until you have the fingerprint data from the tool, the fingerprint data from the tool from a large sample set, and ideally the population, in a relational database that can be used to develop and validate methods and the validated methods to qualify the test results. I also feel there are counter polygraph methods and methods to make variables attributes to effect polygraph examinations failure... even when there is no polygraph exam taking place. Neat project for sure!

    Sure there is a way. A parabolic trough might be even more powerful like maybe using one or two LRAD's where the difference frequency is in the sympathetic resonance frequency range and the amplitude is above the fatigue limit of the target.

    Awesome! Great instructable demonstrating the destructive powers of sympathetic resonance at higher than the materials fatigue limit or structural capabilities. Scary actually in some ways, thinking about the heterodyne capabilities (to increase range like how sound is hailed using ultrasonic, or other frequencies, to create the difference frequency in the target sympathetic resonance range with an LRAD) and pulse train or modulation capabilities that aren't as well disclosed until recently with the U.S. Navy research lab.

Nice because this is a 120Hz refresh rate 1080p system also. We can even take the older plasma TV's with metal cases and retrofit with LED/LCD screens and there is room for more than one computer motherboard to fit with a KVM switch so the system can be made to have the case as a heat sink with added heat sinks if required, a power supply mounted on if doesn't fit inside and be all in one systems wall mounted with bluetooth mouse and keyboard. Just a thought for creative inspiration. Thanks for sharing!

    I forgot to mention Fixya (www.fixya.com), Babcaps (https://www.badcaps.net/forum/showthread.php?t=25836) and just Google searching and researching videos even can find leads and methods to check the specific makes and models of TV's and maybe other devices since reads like there was a period of fake or really low quality capacitors coming in the U.S. from a period of time.

Smart idea in making the pack ergonomic in design to contour the users profile with a hip belt attachment system and even a lower back pad. Shoulder strap extra padding is nice also as well as the chest click to be able to put tension on the shoulder straps at the chest level.

    Haven't figured out the best joint yet. I was thinking maybe 3D printing connection cores and vacuum carbon fiber resin heat cure over. I've seen done with compressed air pressurized to be rigid inner bladder cores also, though would need to be such small diameter, I'm not thinking is as feasible. Might be easier with wood cores (should add strength with resin) and just using tape to compress the carbon fiber resin instead of using a vacuum.

I picked up a cheap harbor freight plastic welding kit to repair the Prius bumper guard and fender after a coyote, then deer about a week later, impact and ultimately decided my old wood burner or soldering iron were just as effective and maybe more durable as the harbor freight iron bent over time. Funny, is after the deer impact I decided to use high temp glue gun as a quick fix that is still holding strong since I had an inverter and glue gun with me. I do touch up now and then the clear heavy duty packing tape to lower drag and as a backup binder.Using the same type material is definitely the way to go. I use more a method like I learned with metal welding and in some cases use a wire mesh (stainless steel preferably or aluminum works too) to iron into the seam if more strength is needed. Other times I'll try to wake some plastic from another area not noticeable and melt into the area to build up more if a weaker spot since maybe was why cracked. For the Prius, I went to a self service salvage yard to find more material. I use the heat gun to form back into shape and then as I mentioned above to weld the seams together.

    About 15 years back when I lived next to Saugatuck and was into photography way more and being motivated to get into shooting video, I was going to make something similar (I wound up making a dual grip shoulder rig with a counter balance battery behind me out of 80/20) and a little boom mount over the camera for audio and potentially lighting. The idea of using PVC is great. Can dampen motion a little also. The idea like you have and I was contemplating was more a reverse backpack style or backpack with front mounts for more a gyro like mount where there is one more axis to pivot to be level with the horizon and the whole rig hangs from the part that I never got around to finalizing. I thought two fishing poles over each shoulder with lines down on each side or hanging from one ove...

I thought two fishing poles over each shoulder with lines down on each side or hanging from one over head hook basically from bungy cord if not directly mounted on my chest... though I like the counter balance ability behind your back. Your design is similar basically... other than if shooting higher up from the ground you can use a longer arm for the balance weight that will help smooth motion and adding another "U" piece with the end mounted with 90 degree ends facing in where your existing bearing go with a bearing pivot point at the middle/bottom of the "U" with a "T" piece to level out horizontal motion. Then mount to your bracket and if long days of filming... the pack options help even more to buffer body movement and balance the load to distribute more comfortably. Neat to see. I haven't seen much for booms or rigs on here.

    Low-Cost Research Glove Box

    Awesome! I'm guessing this is for something biological work as I am thinking one of the above was thinking regarding organic/inorganic/organo-metallic chemistry when thinking about pressure and inert atmosphere purge. Thanks for sharing! I do wonder if there is a pressure concern for optimization also with biologic work which gets me thinking maybe even running a vacuum on the inside to make sure all the VOC's have evacuated the materials after built prior to using to be safe to avoid cross contamination.

  • Outdoor Kitchen - Casting Concrete Worktop With Curved Edges

    Awesome build. I'm thinking I might copy this design with field stone facade for the base face. I was wondering about using sheetrock or fiberboard instead of plywood underneath since making at camp. Any thoughts, suggestions and/or concerns?

    Ammo Can Solar Power Supply

    Neat project! I just ordered two ammo cans from eBay about two weeks ago. two(2) Fat 50 (SAW) Ammo Can Box Used Empty - Very good condition US military Planning on making a rocket stove with one and something electronics project related with the other. Now I have some inspiration as this can be coupled with a radio kit with the right solar panels or use the radio with the solar panels disconnected (have to see what the charge controller adds for noise). Since someone asked the question above, I was thinking using with Lithium INR batteries or salvaged laptop Lithium batteries.Thanks!
