Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun?

So I was shooting my potato gun after talking about car repair today, when I got the idea. Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun to achieve optimal fuel/air ratio? Finding the chemistry of the aerosol fuel would be difficult, and I wouldn't know where to start with the computer stuff, but could it be done? If so, has anyone done it? I searched instructables and no one has even mentioned it. I found on a mazda forum that a wideband O2 sensor may detect the air/fuel ration when using propane, but what about aerosol? Propane in a plastic gun is just begging for injury. I use Right Guard sport deodorant (Without antiperspirant) as the fuel, I think it works the best. The primary ingredient is Denatured Alcohol.

Help please! Repairing trip-up!

Please Help!!! I need help to fix my telephone's mic! I have a telephone at home that was dropped many times and ultimately finished breaking something (e.i. the microphone) so while me being an aspirating electronic engineer (NOOB!) I tried to open up the phone and change the mic with a solution that I thought pretty smart; I learn some time ago that if you change the polarity of a speaker, you can use it as a mic so I naturally opened up the phone and to my surprise I find 2 freaking mics that look nothing like a speaker (or even a freaking mic for that matter) (Picture below). So I was asking myself... Can someone help me to change the mics in the phone with the speaker (Picture of the speaker below, any of the speakers are ok), by telling me about any changes that I have to do or any alert that this might not work (keep in to consideration the voltage, speaker type, and the polarity)... P.S. â€‹II was also thinking about changing the antenna because it's pretty weak!(Pics below). Any thoughts about that? And Thank You! Sincerely; Your hopefully future friend and companion: AntF

Parallel beam of light out of biconvex lens f=45mm

Hi, I would like to create an almost parallel beam of light with an LED and a biconvex lens. Therefore I have to place the LED directly in the focal point. I thought of a setup with a PVC pipe with threading: I could glue the lens to one end and screw a cap onto the other. Then I would drill a hole in the middle of the cap and stick the LED through the hole. By screwing the cap back and forth on the PVC pipe I would be able to find the exact focal point and then fix the cap in place. There is just one problem: Lenses are either incredibly expensive or only available as sets. The only exception I found so far are lenses for google cardboard. They sell for just a few euros on ebay. Google cardboard lenses have a focal length of 45mm and different diameters, I would like to use a diameter of 25mm which is no problem. Now I wonder: Is the focal length of 45mm too small ? Will I be able to get an (almost) parallel beam of light out of this setup ? The LED is no ideal point light source. Originally I wanted to get f>80mm but that is really expensive. Anyone with experience on this kind of setup ? Tips you could share ? Can I get this to work, or will the approach be too unprecise.
