    Double Flow Controlled Mechanical Ventilation

    Great job! Wow, that is really impressive. I've seen before years ago someone implement something the same idea in, or just outside with the plan to go in partially, their wall stud spacing using corrugated plastic from political campaign signs carefully attached end to end with cuts on each end capped to allow a zig zag (not sure if that is correct term) longer length of flow for heat exchange. I want to say they used geothermal also on the intake using 4" black corrugated drain pipe dug under the frost line zig zagged to with an above ground straight pipe intake with a upsidedown "U" shape pipe end.

I wonder if on eBay, as I was looking for aluminum sheet for a solar heater, if you can find "trim ends" or "scrap" that is large enough like from "carolinablades" that might save on material. I've also thought about window screen too as a cost effective way and decide aluminum window screen is more cost effective. Maybe a solar heater intake would be a great addition also? Really neat design.

  • Yaesu FT-450D RF Tap Modification for SDR

    Hi dtrewren, Excellent detail and thank you very much for sharing. I was working on modification of a PRO-2006 Scanner and KTR-1661 and planning on performing a similar SDR interface though found that the CPU/Logic board on the PRO-2006 has issues being able to tune where I am not able to input individual frequencies, I'm only able to tune with the scanner process starting from the top or bottom of the frequency range. I didn't get into the feedback circuitry yet to see how the SDR software can tune the scanner (I didn't think the radio is feasible) and will read more into the Omni-Rig Remote Control Software. That looks really neat.Are you aware of any open source remote control software? I am guessing the remote control tuning software process will be something that will require ...

That looks really neat.Are you aware of any open source remote control software? I am guessing the remote control tuning software process will be something that will require comprehension of the hardware software, command line or firmware code relating to the hardware controls and some sort of process to translate/pass the commands from the SDR software tuning process events to the hardware software/firmware.I haven't yet de-soldered the modifications on the pro-2006 to see if miraculously the scanner will work. Hoping will work then and the current draw goes into specification. Figure some higher power is calling me to learn how to input the individual frequencies and settings on the scanner either way. Again, really awesome detail and excellent instruction! Thanks again for sharing as there isn't much on the internet regarding this interesting way to upgrade older equipment.

    Thanks for the reminder Dave and additional information. I had printed some information from online research when I first received the scanner that I didn't even read into and do have a folder for CS232 and OPT456 that I forgot about. I even have a specification I found somewhere for a OPT535 for a later model. There is a DB-25 port on the unit I have and I had assessed that there is additional memory storage added as another mod, where two switches were added to the back for the different storage banks selection, a tone squelch mod and I forget off the top of my head what the IC socket is on the case.I do recall the IC9 had too high current and last left off there pretty much.

    The Ultimate Guide to Desoldering

    You can buy tips for the heat guns to change shapes and reduce size. I like to use and adapter that has a 3mm dia adapter on that. I haven't made or invested in an IC/SOIC/FPGA adapter yet, though looks interesting.

    I'm looking at investing in a foot pedal bilge (bellows) pump also to see how that works.

  • The 16 Brick Rocket Stove - Quick (30 Second) Build - Easy DIY - Simple Instructions

    In my experience if you want a longer burn... use harder wood and larger pieces. You can use charcoal also. Still, these are meant to be energy efficient so I am thinking they will be still more efficient with longer burn times though you will have to feed based on input size burn rate and potential modification (maybe auger, ramp or other design especially with a sloped input versus 90 degree angle). I have a really generic version that worked great with a Goodwill Store gas burner top that I was going to re-do as I had made with pure clay and need to mix sand and perlite more with I'm thinking since the clay cracked so much before I even fired. I'm thinking I like this idea better versus forming around the cans... even if I do use the same form shape. Awesome and simple!

    Great idea, thanks for sharing. I have to take the heat gun out today for a different project and if I wasn't on the road working, I'd make this for my workshop. Very convenient.

  • How to Connect PET Bottles for TrussFab Structures

    Awesome way to re-use waste where recycling isn't available or if user wants to. There used to be links online with someone, I want to say in Mexico since may relate to Mexico City once being a lake where floating gardens and waste merged into land covering the lake, making a houseboat also with yard area on top of bags/nets of plastic bottles. I've never seen anything like this. If you fill them with fluid you could store heat and also to equillibriate your environment slower. My Dad would do that with the hoop houses, green houses and in the basement.

    What is that?

    I found, there is a kit on ebay for #1 and #3. I also found this awesome link that isn't really related though on the 3D printed version of this on another instructable I noted placing in a vacuum with a magnetic clutch. Thanks a bunch for noting! http://www.pbs.org/wgbh/nova/blogs/secretlife/blog...

    Here is a better link that is more pertinent. I've never studied the history of the solar cell. : http://www.beatriceco.com/bti/porticus/bell/belll...Man, can probably make a solar cell now days. I have been encouraged to work for Bell Labs and also study solar cell technology. My focus of encouragement for the solar cells was in regards to my organic synthesis and biochemistry background. Even the foundry experience may be pertinent coupled with Process Analytical Technologies work experience too. DIY high purity silicone would be something else. I need to study electrochemistry, electromagnetism, math and physics more however.

    Solar Mendocino Motor

    Neat. Wonder what the RPM, horsepower and Torque is on this. I'm guessing now I think about after typing we can calculate based on the solar cells, magnets and windings. Be interesting with a flywheel too on a larger scale. Magnetic bearings alone are the coolest. Makes me think there can be a magnetic clutch added to an end where the motor is in a vacuum chamber of glass so as a system to act as a capacitor since could go to high RPM's potentially. Awesome, this is really neat!

    Good call. The table top "scroll saw" (or that is the term that is coming to mind to me) type hot wire cutters are new to me. I used to have a hanging or held in my hand 2"x2" 3' long piece of wood with two 1/8" holes drilled in the end perpendicular to the length at a slight outward to the 3' length angle and about 6" of 1/8" metal rod (I forget if was spring steel, piano wire or what from the hobby shop) that was inserted into the holes with maybe 1/2" protruding through the inner angled side. that is where I attached the transformer.

The other side used the nichrome or I think I even used piano wire with hook bends at the two ends if not loops for the nichrome wire. I think I even put little notches on the 1/8" 6" length pieces maybe 1/16" off the outer angled side bottoms for the wire to seat better. This was for cutting longer length segments of foam for model airplane wings or fuselages. Thanks for bringing back the memories and inspiring for a new build. Your design is really effective.

    Awesome! I have an old Tyco Type 1 AC/DC model train transformer that I used to use. Your improvised design is the best! That is way creative and resourcefully innovative! Thanks for sharing!

  • Shop Air Filter Fume Extractor Combo

    Great design and very simple. You can almost make a laminar flow hood when operating in reverse if using a more thorough filter like a HEPA filter and maybe even some other sterilization processes (UV/Ozone/Electrostatic) in the box. Most don't grow mushrooms, though this would of been handy back when my family was growing shiitaki, maitaki and some other fungi. You could also add a glove box for chemical/biological work. Now days I like your design for soldering. I am guessing the filters you made are more cost effective than purchasing? Otherwise, like someone noted below... furnace filters may be helpful though not so chemical/element vapor absorbing is my thought. Thanks for sharing!

  • Learn to Surface Mount Solder Using an SMD Challenge PCB

    Oh, some soldering pastes are recommended to be refrigerated. High volume I've seen automated pump stations for paste made from glue dispensers. I think on Instructables.com also.

    I actually like the speed of the GIF's. Excellent tutorial! This is I think one of the best Instructables I've read and watched that covers the very basics of SMD soldering. We can search the web for more information on temperature controlled reflow ovens, using heat guns and maybe a wick to clean pads if were more sloppy. Other than that, I can't think of anything at the moment to add. Maybe temp of hot iron and work fast? Thanks!

I did pick up some poly lycra for window treatments that I made and I still use in the car. I was going to sew a sleeping bag cocoon also with the remainder of the material. Also, with the SPF50+ light weight materials, I wasn't sure about details for sewing. I still have to research sewing the clima-lite, coolmax and polylycra materials. Any suggestions for the two extremes, i.e. leather and poly-lycra?

  • How to Use a Pressure Cooker (and Choose Which One to Buy)

    Great instructable. I'm going to have to look into the induction heating pressure cookers. That seems interesting. I have a Power Pressure Cooker XL that I like, though isn't like the old fashioned college day version. However, I like the combination of being able to use as a crock pot especially for roasts.

    What brands of the induction models do you use? I was thinking for on the road using a pressure cooker and I forgot about the time to warm up on top of cooking time when I invested in the Power Pressure Cooker XL. Work's great as a crock pot also... though I do like the older versions on the stove top. Would be nice to have something made out of stainless steel to and not have coatings that have flourine. Now I am looking back at induction and can use some advice.
