    So, after all this time searching, I found this document that I drew up while sorting out the pin numbers as to their function. I cannot find my original project

    First off, my Instructable was never about telling you the wire colors and what they mean. It is about taking known part numbers of the components and from the components datasheet, extract the ground pin and the positive pin. The Datasheet will also indicate what voltage. If it is less than +5 VDC, there will be a voltage regulator (probably a 3-pin device) between the USB +5 VDC and the chip's voltage input pin.So, once the Ground and 5 VDC pins are found, that leaves two pins left, +data and -data. The thing to remember is not all manufacturers use the same color codes.

    I've rearranged my shop space and don't have ready access to that project at this time. it may take a couple of days to get back to you about the Test Point pad to Connector cross reference. personally, I'd just carefully cut off the top of the connector and attach test wires to do a pin check with a DMM and follow the testing for pins from the connector to the different chips. I started doing just that by researching the component datasheet PDFs and checked continuity between the chips' outputs to the connector. Also, don't forget that the big circles on the underside are grounds!Ricky

  • Great idea! I would hope that someone with a 3D scanner can get their hands on a respirator mask and build a hard, sturdy frame. Then maybe use Type 2 plastic (recycled milk and distilled water gallon jugs) and a hair drier to form the Type 2 plastic to conform the the mold. If anyone gets the 3D scan completed, can you turn it into a STL file and post it on GitHub? Of course, the Type 2 plastic would have to be washed and sterilized first. then check out a GitHub post called Ventilator (https://github.com/jcl5m1/ventilator) I think we can open source with jcl5m1's GitHub post and do great things!

  • I was looking at that referenced link above and came to a GitHub link https://github.com/jcl5m1/ventilator I think this would be something for you to build and inspect to see if there is anything that needs improving!FYI the credit for this goes to jcl5m1 . Great Idea!

    Hello Dr Rilyas!Check out this link https://www.vice.com/en_uk/article/5dm4mb/people-are-trying-to-make-diy-ventilators-to-meet-coronavirus-demand it is loaded with pertinent info for you. I am gonna try to do what you are asking about to see if I can put together an Instructable for a low tech, inexpensive ventilator.

  • Hello! can you post a picture of your battery? Also, is it a 12V Li-ion battery like in an old RC car? If the battery you have now is a Ni-Cad battery, check out how to salvage old laptop battery packs and properly drop off the Ni-Cad battery at your nearest recycling center because they are just too old to work with in the future.If it is a Li-ion battery pack, there a whole new group of different approaches to take, starting with Orngrim's post. So upload a photo of your battery and lets go from there!

    The problem you need to first work out is how your USB camera wires are to be hooked up to the USB cable. Once you get that issue resolved, then pull out a DMM (Digital Multiple Meter) and chose the lowest setting for you DC Voltage. With the camera operating (I haven't figured this one out myself) I would suspect when you talk, you would then see audio wares on your meter. Also, try to research the camera chip and see it it incorporates the microphone pre-amp inside (or level converter from low voltage to a higher voltage like the +5 VDC range).I made several of the USB cameras, but didn't do anything with the mics. I may have to research more and try to do another Instructable similar to this one. Keep me posted if you can resolve this addition. I'm guessing that you will have to add a…

I'm guessing that you will have to add a booster/amplifier of some type rather than connect to the regular 1/8" microphone plug on you computer.

    So, what it is from is not as important as what the module looks like. Can you upload a few pictures?

  • These are a few LCD displays I had to work with. You will note, I bypassed the adjustable intensity altogether. I did nothing fancy, just reverse engineered what pins to connect to what outside sources and viola! the screens lit up!The two pins connected together in all the models I have listed below may be played with to get an adjustable dimming.
