    Yes! my good friend. You're thinking of a classical figure eight Mobius strip! but a triangular Mobius strip can be made from a piece of paper that has a length that's √3, or about 1.73, times its width. :) I know! but you are my rock. You pull me back down to earth and I thank you for that...

    Where to add a potentiometer to vary input voltage?

    Thanks to everyone for these fine examples. I was planning on doing the same. To thread starter; forgive me for barging in, this is your thread alone. I simply had to express my gratitude for the two explanations and schematics thanks again. "We are not here to see through one another but to...

    I love cats I wouldn't throw him down into a Mobius strip he will be repeating himself for eternity. In real life two human beings are doing that already. ;)

    Laser retro reflector for non-contact odometers.

    Correction: Exiting Wavefront and Beam Deviation are interrelated please specify one or the other. I need to know the resolution you seek.

    Laser retro reflector for non-contact odometers.

    Welcome to Maker Pro :) Need to know: mounting system; ball mount,hard mount etc. Spectral wavelength in nanometers. Beam deviation in arc seconds Exiting Peak to Valley wave front deformation. These specifications will dictate the type of retro reflector needed Prismatic or orthogonal.

    Modding a lamp

    I'm worried when you and if you cut out the speaker,you might have shorted the wires together by accident or a bare wire may have came in contact with another part of the printed circuit board if you had cut the wires one by one then you're okay. In these little toy audio amplifier output...

    Modding a lamp

    Does it have a volume control knob on it? You know what forget that last sentence I guess it won't hurt you already have it off took the speaker out so.. I don't think you could repair or do any modifications. enjoy! I don't think I can help you sorry kiddo.

    Sorry about the spelling I'm on speech to text I guess I'll say that up front from now on. If you would like to someday hear the audio again then it would be wise to terminate the transistor to an L pad which would replace the speaker You see that little green blob it's called a (cob) "chip on...

    Do you know how to solder? If you do know how to solder, solder that speaker back in. To confirm that you didn't pop that transistor already you don't have to see physical signs damage on that transistor for it to fail. I got to go kiddo got to go hiking with my doggies.

    Here's your audio amplifier kiss that little transistor goodbye! Would you happen to know how to use a multimeter since you already have the speaker out or disconnected measure resistance of the speaker it'll give you an approximation of the value resistors to use. You going to need more than...

    Man... in all my years...I never come across that quote from Mark Twain. Thank you sir for the information.

    Thanks for scaring the bejesus out of me!! You're asking the question after the fact.. amplifiers need to see a load which is the speaker so I get it about adding the resistor. Take a photo of the speaker you pulled out. The backside I need to see what's written on it

    Part identification help?

    What a small world! ;) I work live and play right by the Huntington library. I feel like fixing it for you! For free... Forgive me if you have already tried Yelp. Two of these companies I have used but not for IP cameras for other security measures. If you're not satisfied with any of these...
