  1. Closed: Re: RF Transmitter - Pulsing sinusoidal wave @ 10.5K Hz. Pulsed every 36ms

    Thanks for the quick reply! After reading it I figured i might as well build thing thing to run off of 9v since it is a readily available, inexpensive battery type. I suppose i could just ramp the...
  2. Closed: Re: RF Transmitter - Pulsing sinusoidal wave @ 10.5K Hz. Pulsed every 36ms

    Thank you so much for responding. As you saw in my other post I was able to build an Anduino-based version of the transmitter, but this new microcontroller method you have proposed is very...
  3. Closed: Re: RF Transmitter - Pulsing sinusoidal wave @ 10.5K Hz. Pulsed every 36ms

    Thanks for the feedback! Before i saw this I actually built a transmitter using an Aduino Nano and some code. Now that i have read this I am very interested in the PIC200 method you mentioned. Do...
  4. Closed: Need to boost 10.5KHz RF transmission distance from 4" to ~25+'

    I built a remote transmitter for my cat's shock collar using an Arduino. It is based on this circuit and code: https://www.instructables.com/id/Arduino-PetSafe-Cat-Barrier/#CPW6UOMJI0JKWIT

    It...

    The builder mentioned an easy way to build this using a 556...
  6. Closed: Need to power 1.5W 5V load with a battery /recharge off solar.

    Hi everyone, sorry for the noobish questions but I’ve been trying to figure this out all day and I need help.
    I have a 1.5W 5V (USB) load I want to power with a battery and have the battery recharge...
