    uW energy harvesting

    hello, I was reading in multiple papers that some researchers will use a weak power supply to power electronics that are at higher power demand. They do that by using a capacitor and some circuits to store energy and releasing it at once when it is enough. I believe the circuit will maintain...

    Ultra low power transmitting for short distance

    Hi, I am using a small battery to power both a sensor and a transceiver to send a signal for ~500 meters. I am looking for the lowest power-consuming method. I don't really care about how low my transfer rate. 1 sample per 1 is good enough For my sensor, I was thinking of using a Thermistor...

    PsOC 4 BLE (pins problems)

    I am running a project using a thermistor. I started by using the evaluation board as shown: The program runs fine. After that, I removed the module from the evaluation board and powered the module using an external power source (3V). I moved the resistor and thermistor from the evaluation...

    Converting 1.5V from AAA cell to 0.8V output

    Hi all, I'm designing a circuit that needs to take 1.5V from two AAA cells in parallel and outputs 0.8V to a DPDT toggle switch (on-off-on) that connects the load to +0.8V, 0V, and -0.8V depending upon the switch position. The output current would ideally be able to reach up to 1.5A for safety...

    Help with EMI Ferrite (magnet?) Rings

    Could someone point me to where I can research, measure, calculate, and/or size these ferrite rings if voltage and rough max amps are known? It's for 5, 12 and 24VDC low power system pulling up to 2 to 3 AMPs per run. Some amps are far lower. Also would like advice about bundling several...

    Understand low power gate timer TPL5110, any alternates?

    I was reading datasheet of TPL5110 it says "the TPL5110 has a unique One-shot feature where the timer will only power the MOSFET for one cycle." I do not understand what does it mean by "One-shot feature" and "turning on MOSFET for one cycle" here what does it mean by one cycle? I want to turn...

    Cat tracking collar

    Hi, I'm trying to build a radio beacon that would be mounted on a cat collar. The goal is to get the distance of the cat - every 10 seconds. - for ≈ a month - with a ≈ 30 metters range detection - through walls - can fit on a cat collar (battery + electrical components) Would it be possible...
