    Ultra-Low Power and Long-Range Design of LoRa Modules

    Hi, I am working on a similar project, and tried to change settings, using a button press menu. I found a problem where for my system to work all the settings need to be the same for it to work, so, as soon as one changes the other is incorrectly set, so failed. I am using a repeater, so this...

    YI car camera hacking

    Hi, Here is a photo of the schematic, in case it helps find either the wifi or composite output. C

    YI car camera hacking

    Hi, I have a couple of YI car cameras, which send vision to a mobile phone, and saves videos on an SD card. The range is poor, so I'm exploring different ways of imroving this. Either boost the wifi, or find the composite section on the schematic, and transmit it via radio. Any ideas welcome. C

    Programming PIC to sontrol 6x SERVOs

    Hi N, Thanks. As #59, I used a shift register, to cycle through each SERVO/MOTOR, while leaving each one on for the 'set speed' time. C.

    Wireless momentary switch

    Hi C, I use HC-12 radios for this type of thing. I use PICs but a mosfet connected to an Arduino witl do it. A small PIC can have 8xlegs. C

    Programming PIC to sontrol 6x SERVOs

    Hi, I received help from another forum, and added a 'shift register' to my PCB, this switches in a loop round all SERVO/MOTORs and sets an angle or speed for each one as it goes. It's working fine. C

    Bias_T and inductor resistance

    Hi K, I checked small Caps e,g, 10pF and it worked fine, within 10%. I'm interested in the LC oscillator, and I'll ask again, when I've got time. Thanks C

    Bias_T and inductor resistance

    Hi, I've just posted another one, forgetting that this one is live! Anyway, I bought the #14 ones, but now I find they can't read the small value inductors I need to read. Is there a way I can read them, withought spending any more money? C

    Bias_T and inductor resistance

    Hi, I've just bought some component measuring tweezers. They look ok, but they aren't able to read uH inductors, which I need to do. How can I check the values of uHinductros. Camerart

    Bias_T and inductor resistance

    Hi K, Thaks, I want them for surface mount compnents, so these will be fine. C

    Bias_T and inductor resistance

    Hi K, This looks like the one shown earler. Thanks I'll consider it. I'm looking for tweezer type, if possible. C
