Re: Brighter LEDs

How many of these LEDs can I run off of my Raspberry Pi GPIO? Directly? None if you want your Pi to live. 0.03A is 30mA which is more than the GPIO pins can supply. Forward Current is the same as the current they actually draw, but can be limited by the resistor used. A larger resistor will reduce ...

Re: transfer pictures from PI to windows PC without SSH

I believe that windows assumes that SD cards can't possibly have more than one partition, so ignores all except the first one.

There are ways of getting around this, but as a non-windows user I don't know which software is needed to do it. It has been mentioned on the forums before.

Re: Voltage difference between PSU and test points

F3 is the large green (usually) polyfuse on the underside of the board near where the microusb connector is (on the other side). It is large enough that you should be able to hold a test probe on each end to measure the voltage across it, which could be the drop you are experiencing.

Re: How to identify which RFID it is

The current kernel that my Raspi is running (3.10.25+ #622) has CONFIG_INPUT_EVDEV set to "m", which basically means it is enabled, but as a loadable module, not a built in driver. Don't worry about that, it just save memory as it isn't needed in most systems. You can load it by "sudo modprobe evdev...

Re: Voltage difference between PSU and test points

Are you still powering via the micro USB power socket? If so, try measuring the voltage drop across F3. It does always have some resistance, even when not "blown".

Also test the drop on your power cable (some uUSB leads are appalling!).

Power. The usual problem is inadequate power. Forget what the label says on the PSU. Try another one. Try another power cable. Measure the voltage between TP1 and TP2 on the board - it should be between 4.75 and 5.25V, the closer to 5V the better. I don't tend to run my Raspis for long periods, but ...

Try just one more thing

I don't understand why you are running those commands. Why would the SD card/reader show on the PCI bus? The reader is a USB device, is it not? Try lsusb and see if it shows up there.
