Re: Coburns take on powering the Raspberry Pi via batteries

<t>Sorry, you are right. I did not read that line.<br/> What I do not understand is the charging current. Why should I want to change the charging current from 1.2A to 100mA? In order to protect the battery with slower charging? In order to charge a smaller capacity battery? or in order to give more...

Re: Coburns take on powering the Raspberry Pi via batteries

<r>I was thinking on powering the Raspberry pi with something like that. I already saw the charger you mention but I was unable to find some technical details about that product. It is not specified if the charger is able to charge the battery and drain power from battery or power source while charg...

Re: Using RPi as a Standard Robotics Interface

<t>My approach would be to use the RasPi in conjunction with a UBW or a cheap microcontroller with some extra components. Use the microcontroller or UBW for ADC, PWM, etc. and take advantage of the cheap USB peripherals we could add without extra coding attached to the RasPi. For instance, a Wifi, G...

Re: Coburns take on powering the Raspberry Pi via batteries

<t>I am not an expert in electronics and correct me if I am wrong but I think that one of the main advantages of super capacitors would be the charging time. You could charge them for 10 seconds and have them powering your Raspberry Pi for almost 3 hours. If you loose the charge you just charge it a...
