  • The Perfect DIY Solar Oven

    Use of Oven Bags for wind protection clear screen. They're made of a heat resistant Nylon that is FDA approved. Reynolds Large size are (16" x 17 1/2") and Turkey size is (19" x 23 1/2"). Would be great to see how the cooking bag as a covering lasts over time compared to the clear covering used in your design. I'm also curious the performance of covering the whole box compared to covering (bag) the cooking vessel with the oven bag now that I think about. Both would be great research projects for those that have the time to perform. Also, if you're in a jam to clean there are slow cooker liners that might help for those that do not have as much access to water for cleaning. Thinking those can be folded down for storage until you can clean and then use a roller to sm…

  • How to Make Roller Stand From Old Treadmill

    Great idea and awesome application! I've been wanting to make a sod cutter with the same parts I've saved from a few and been wondering about other apps like adding a larger anti-scalping roller to the front of a rider or garden tractor deck. Was also planning to make a lawn grader leveler rake, upgraded rototiller, dump trailer and a manure spreader with parts from them or like with the manure spread most the deck. I've actually started working on the dump trailer and need to document as well as move forward on. Was waiting to plan a day to weld, since need to practice FCAW, with my machine and flux core spool(s), on some of that thinner material before I proceed with the fab. Thanks for sharing!

  • Mini CNC Milling Machine

    No need to apologize. I comprehend. I'm thinking with "road" you are meaning "erode" or "wear" the surface. In regards to the datasheets, for one manufacturer the bearings read 0 to -0.013 and assumed mm... though maybe is micrometer. Guessing varies with manufacturer. I was just reading there are polymer versions, made of "Drylin", of the bearings \ that recommend not using grease. Wondering what those Drylin bearings are like in regards to long term performance. I was also thinking last night about Chrome plating to salvaged rods to increase the diameter... though that would be a lot of work and most likely not easy on an already polished surface.

  • Mini CNC Milling Machine

    I just checked the range of 6mm rods and they're measuring 0.234-0.236", so an even worse specification of 5.94-5.99mm potential. Interesting. I just found the assumed 8mm rods range from 0.312-0.314" confirming and even worse range of 7.92-7.98mm potential. HHhmmm... and I was trained to assume nothing. Can tell I'm retired on a pension, doing more physical labor than I need and not thinking so sharp as can be. B^|) Has me wondering more about actual bearing specs based on their reported tolerance and what is more typical variation along with probability of oversized versus undersized batches.

    Awesome observation! Thanks for the feedback regarding. You can definitely tell I've not mic'd the rods yet. Are the 6mm rods not true also?

  • Mini CNC Milling Machine

    Great detail and info. Appreciate that. I recently found another source of nice polished steel rods, old shocks. The 8mm rods can be found in certain copiers and printers at the lengths required. HP inkjets are great for the 6mm and 8mm polished rods. I'm not certain yet what to make with the tub material from the shocks... though the polished rods have me thinking something like your design. Certain copier brands used to be great for the stepper motors. The above can be found free sometimes. Wondering about waterjet or plasma cutting steel instead of plywood to make an even sturdier design for metalworking. Guessing offhand might need a better lead screw design and bearing blocks... though maybe not. Thanks for all the info!

    Your welcome, thanks for detailing so well and easy to follow. Wound up looking at the rectifier photo closer and saw the make and model on the face. Then read into some more and reads like that Tekpower linear PS are a good build. I'm currently working on some other projects at the moment, a webcam spectrometer, garden tractor & implements and some welders repair and customizing. I have an old Harrison 6201A PS that I think is suitable for using when I get around to. I'll definitely post some photos if and when.

  • Speech Recognition With an Arduino Nano

    Yes, makes sense however from my perspective which isn't speech analysis and most likely thinking from a significantly more intense processing perspective, my thoughts are the finite variations of a speech spectrum (and even reducing to most significant variation) can most likely be modeled. Then similar to frames in a movie, or more literally averages of a real time analog signal digitized with some sort of input process to determine when to scan whatever the parameters are, the patterns can be trained, modeled and recognized for a more next to real time or near real time assessment.

Thinking possibly as a check so there is no alpha or beta error. You're correct however, my work was definitely constrained to procedures where the signal spectrum was from a saved moment in time per a specification. However, I'm confident the process of the analysis can be performed dynamically once trained, modeled and discrimination variables are developed and validated. Basically, the "spectrometer" or whatever signal analyzer or spectrum analyzer is just left running also with some sort of input process to trigger whatever wanted discrimination. I was even able to characterize different sources of noise in the environment... though like most of my work... I didn't focus on that application or publish. Really neat the minimalist approach which makes most sense to me... though the corporate World can definitely create business processes to keep more busy and strange even programming languages to use that bogs the processes down and takes more time. Neat you worked in radio-spectrum analysis for counter espionage... yes... that's why I was amazed with all the resources overt, covert and clandestine dedicated to detection of signals... that nothing was detected with all the reports of "health attacks" other than some cheesy sonic recording on a cell phone with a situational awareness of no audio forensics propaganda regarding. That's why when I posted my sonic and ultrasonic recording, albeit cheezy also and under duress/assault post malicious destruction of personality etc., I still to this day am amazed the only main stream recording exposed was about a week later main streamed. I wanted to post the beam forming signal I found also in the RF range... though wow... why I never signed a NDA or a government contract. Doesn't help with the U.S. Jurisdiction allowing more foreign ownership of U.S. assets either. That's another topic, though nice work and I wonder also about iterating the signals through algorithms with different combinations of the range of most probable properties, parameters and attributes like say sampling & sampling rates to identify at least the sound/speech assaults. Requires training though.

    Invisibility Shield

    Your very welcome and thanks for sharing! I recall someone using the projector screens and I've not been able to find the video on Youtube. Greenpowerscience however, notes in I think more than one of his videos about the difference in the Fresnel and other lenses from the projection screen TV's and how challenging to find (if not making somehow by polishing off a layer or something like that) the circular pattern since many of the designs are the linear pattern. Ah, just looked and found one of the videos regarding the lens patterns and conversion: https://www.youtube.com/watch?v=zjrB9wbJfMw

    Some of the projector screen TV's if I understand correctly, Fresnel Lenses are a linear type and not the circular ideal point solar concentration type. If I understand correctly, those specific linear types of Fresnel Lenses are a lenticular design. There is also a 3D LCD TV that uses a lenticular design (I just checked to verify): https://en.wikipedia.org/wiki/Lenticular_lensNot certain if the design is rounded or triangular and the effect on the invisibility perception.

I was also planning to update for additional external battery inputs... though never got around to adding the beefed up wiring and traces assuming the transformer could handle the current.

I'm just not certain how much helps with a DC line and where to place since seems best to be before the rectification... though I recall might still function for DC though I keep thinking will block like a capacitor maybe. Though I know the capacitors when spec'ed correct cause the DC offset Voltage to level out and stabilize post rectification. Thinking the inductor will do the same for Current.

  • Creating Easy Glass Circuit Boards at Home

    Neat, I watched the video a few weeks..., or seems like months, back on Youtube. Interesting method and cool to see and read written down on instructable. I was wondering if there were different conversion methods used that adversely or didn't adversely effect the quality of the PNG's as I found also so did SVG. I wound up using this method that I documented in a poor video since I don't use much. https://www.youtube.com/watch?v=LW_gfwOTEDw Reminds me I can make an instructable regarding maybe too. Thanks for sharing the elegant design in English on here also!

    Solar Coffee Maker

    Great thinking! Nice detail and paradigm of thinking regarding re-purposing something to save energy also and being super simple to make. I've wondered about using the HID lamp hoods for use with solar vacuum tubes or just in general metal tubing maybe with a high temp paint or ceramic/clay black-oxide (old D-Cell batteries maybe?) coating or just as-is. Seems like radiant heaters heat exchanger with fins can distribute the heat more and lower the focal point temp to distribute to a larger surface area... that idea might be useful and material found to salvage. In regards to reflectors, the "Adjust-A-Wings" look especially interesting since have two parabolic troughs and I've wanted to try... though haven't got around to since not being off the grid as I was for a time.

I've never seen a parabolic lamp shade commonly, though am wondering if dentist lights maybe have? Looks nice and I wondered for say cooking a stew in a pot for the day about tracking also. That can be done rather easy with a simple tracking circuit or cost effective MCU with a search of instructables for solar tracker and then instead of the servos moving only the solar panel... the servos, or instead re-purposed motors, move the dish.Are you planning to make a solar coffee maker track the sun also?Thanks for sharing! P.S. Neat to see and motivates me to get back to work on my signals tracking project using some dishes I've found online for free off Craigslist, Offerup, Letgo, Facebook Marketplace and other listings with the cheap RTL-SDR's for starters and a Small Board Computer (SBC).

  • (Inexpensive) NOAA APT Ground Station Utilizing the RTL-SDR and 3D Printing.

    Excellent detail, thanks for sharing! The later advice for re-sampling the signal is greatly appreciated, as I've not read that before and makes sense for signal pre-processing. Amazing how some signals are present, though not even audible until the sampling settings are correct... not only for the carrier signal, for the modulated sound/signal too. Thanks again!

  • TRADITIONAL  HOUSE USING PACKAGING BOX

    I have an instructable that starts off with some great background references that shows how to make an RF detection system cost effectively to detect some serious issues and concerns I've been advocating awareness of so there is more evidence collection for enforcement to defend against. I'm thinking there are other instructables also to learn about RF devices, though mine might be a good start to see what you can salvage and re-purpose and use to learn more about RF devices. https://www.instructables.com/How-to-Make-a-Directed-Energy-Weapon-Detection-Sys/I'm also planning this month to make some more instructables to detail making and using the antennas, some other under $50 RF equipment, some other software applications related to RF equipment and a worksheet for therapy.

  • TRADITIONAL  HOUSE USING PACKAGING BOX

    Interesting you posted your new videos today as I just noticed this in my gmail inbox getting back from investing in some laser cut cardboard hardening material methods products, i.e. Durhams Rock Hard Water Putty and Titebond 2 Premium Wood Glue. I'm planning to mix the two to coat the cardboard antenna form I made at the local Fab Lab. Then depends how performs... I'm thinking I might coat with fiberglass resin (polyester) to waterproof and make harder.

  • UChip - Serial Over IR!

    Awesome! I was totally hoping this would make it to the market... and just found out it is... or at least in Italy and looks like Europe. Do you ship to the U.S. and outside of Italy? For under $15 seems like an awesome price for the package... I mean... if specs like a Arduino Zero... then how not?I'm thinking this is a great package for the tinySA also since the Arduino Zero is the typical MCU used in the design. https://github.com/erikkaashoek/tinySAThanks for sharing!

    Nice! The open source ID system is an excellent idea.

    Will take a look, just scraped the video and will read into and watch later... then when I have the time watch the youtube video all the way through for their metrics. Interesting idea. Wondering about using the amplifier from an active mini-whip or E-Field antenna amplifier now with the MEMS and transducer dodotronic's noted. Budgeting in for next month.

Have to check the messages since I think the seller noted he has better material for and can custom size also. Amazing what can be made with free TV's you can find on Craigslist, Offerup, Letgo, Facebook Marketplace and other online "Free" sections that people just throw out. The plasma TV's make great computer cases also for use with custom LED/LCD screen replacements... plus you can harvest electronics parts and practice desoldering/soldering if not repair with the boards. Thanks again!

  • Intelligent Bat Detector

    Excellent dodotronic! I was wondering about the SPU0410LR5H as I saw listed on eBay and not the SPH0611LR5H that Franzis noted using. Looks like the SPU0410LR5H is in stock at Digikey and a little better price than the SPH0611LR5H. The FG-23629-P16 is in stock too, though costing more... I'm thinking easier to work with integrating into existing systems. Obviously, your Ultramic 384K BLE microphone seems the easiest and most cost effective for use in standalone or existing system integration. Thanks for the support, feedback and experienced insight.

    Neat instructable in general. I've never seen this done before. Cool! I imagine a lot of possibilities with shapes, dyes, colorants and molds to pattern stone looking textures also. Wondering even with furnace cement for high fire work. I have some white portland and white sand and am wondering how will turn out with the silicone molds/stamps I made from some tiles.

    Build a Soundproof Wall

    I recall there is a method that may be more modern where some sort of filler is sprayed throughout the area rooms that follows the path of least resistance and basically fills all the air leaks in the walls to the point where the pressure in the room trips the system to stop spraying since all the leaks are sealed and the room is pressurized. Then the additional acoustic and RF systems are implemented. Any ideas what that system is called? I forget and that system is impressive in regards to setting up, sensing in each room, operations controls and operation. Granted some form of ventilation baffling I assume needs to be implemented when the designs are that sealed from transmission/penetration.

Do you know how the airways are ducted and vented to make sound transmission and even RF minimized or almost eliminated? That I've not observed, read or watched regarding. Interesting seeing this article too, since earlier today, I spoke with a gentleman who noted he used to work for a company that made modules that opened on each side so were basically an intermodule shipping container time three width and were invisible (electronically). Someone had to come out from California to test with the range of RF, though the systems were invisible to the others systems, yet he had to be able to detect all those systems stations. He noted they silver lined everything with special seams coverings also, I guess RFI/EMI gaskets too. I'll have to ask him what they did for ventilation, any ideas?

  • JamesA41 commented on TheDIYPlan's instructable 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

  • 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.

  • 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!

  • 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.
