Re: Advice about screen

I am slightly disappointed with screen quality as well, but you have to accept it as cost for simplicity and low price. There are three basic ways of how to output video signal from RPi Zero - HDMI, Composite and SPI through GPIO. For start we can forget about SPI (or other GPIO) screen, because the...

Re: Is my ribbon connector faulty?

It was same with mine, i believe this is one of minor changes of v1.2 PCB revision. The flap can be locked, but it is really hard. I fought with it for several minutes as well. My recomendation is to push the ribbon in as far as it can and then start pressing with your fingernail (or other suitable ...

Re: Lightning button on the rear...?

On v1.2 revision (second batch) devices it does nothing on default. But it is connected to one of the GPIO pins of raspberry (specifically GPIO 17) and it can be accessed from command line, through script or other programs. So in theory it can be used for anything and only your programming skills ar...

Re: Charging is too slow?

If slow charging due to overheating is issue, it might be worth to try some "slower" charger, like 500 mA. Heat dissipation on charging circuit is product of voltage drop and current, so if you reduce current, you reduce the heat. This of course lenghtens the charging but beacuse of how li...

Re: Charging is too slow?

The combination could work, but unless you are perfectly sure about what you are doing I do not recommend it. Trouble could be with quality of the power source. Those chap "universal" sources are quite often not or poorly stabilised and filtered, which is perfectly fine for powering of sim...

Re: Using Battery Indicator Button as a Controller Button

It cannot be used as Controller Button - at least not in default state. This button is connected to GPIO pins, that is as internal hardware signal. However in default setting Retropie recognizes only USB input devices and GPIO does not behave as one. In order to do so, you would have to configure th...

Re: raspiboy possibly damaged by mistake

Can you clarify what is your present RaspiBoy status and what is your problem? From what you are describing it seems you are worried the PCB is damaged, but you did not find any damage and device seems to work (or at least charging. Is that so? If yes, then although not recomended - this should usua...

Re: 1 hr battery life

I would say suggestion given by Pierre about increased consumption due to flash drive is most probable. Those devices can be quite power hungry unless managed properly by OS, especially at bigger sizes. Trying it without drive is first think you should try. But there is also another way how to verif...
