Re: Warrenty of the Pi ?

Because that connection is not required for normal operation. I've been using Pi computers for years and never found I needed it. Modification of almost any product will void the warranty. That's pretty standard warranty stuff. It's actually quite rare to find the opposite, so you should have thoro...

Warrenty of the Pi ?

Hi. Can somebody from the Pi Foundation please clear something up for me. The Pi run / reset pins do not come populated with pins. I was told I had to solder them on my self. I bought 7 Pi boards for a project I am working on and soldered the pins on as required. I found one of the boards did not bo...

OK that seems to have done the job. Sparkie care to explain why I may not comment out lines that was not required ? I like to know why things work the way they do.

Re: How do you force a wifi interface to be a certain wlanX?

No this is a Jessie install. OK I will change the file as stated and test. I have a bunch of Pi's out in the field. They are still on Jessie. I created 5 new ones and they all seem to work with the config. But they are stretch images.

Re: How do you force a wifi interface to be a certain wlanX?

I have one Pi that does not want to set the dongle to wlan1. Why would it do that ? The dongle is in at USB position 4 or where wlan2 would be. It makes the onboard "rename4" and the dongle wlan0.

Re: Run/Reset pins will reset the Pi if I close solenoid valves.

OK. One more thing. Why are these pins not soldered on by default ? Do I loose my warranty if I solder them one myself ?

Re: Run/Reset pins will reset the Pi if I close solenoid valves.

The wire is about 15 cm. So if I understand the solution correctly I should do the following.

1) remove the relay I was using to bridge the run pins
2) replace the relay with a optocoupler close to the reset pins
3) use a short wire to drive the optocoupler

Is that what I should do?

Kind regards.

Re: Run/Reset pins will reset the Pi if I close solenoid valves.

How are you powering the solenoid? What BJT or MOSFET transistor do you have between the GPIO and the solenoid? Have you thought it might be the sudden in-rush current for the solenoid that's shooting the RPi dead rather then the RUN header being shorted to GND? Hi. How can that power reset the pi ...

Re: Run/Reset pins will reset the Pi if I close solenoid valves.

Why does the Pi do this ? I have now gone with another solution. I have created a read-only image where we can just remove the power. So I am no longer using the UPS module and reset pins. But Why does the Pi reset when not even connected to anything on the other end ?

Readonly Image time is wrong [Solved]

Hi all.

I followed this tutorial https://www.raspberrypi.org/blog/adafruits-read-only/

All seems to work fine except the date and time is wrong. It seems that NTP is not working anymore.

How can I get that back ?

Any idea on how to stop this ? It seems that wire is acting as an antenna and picking up the power in the air.

We also get a reset with just the wire connected also. In fact the Pi will reboot if it is running off battery with no wires connected to anything. We only have the wire connected to the reset pins but the other end not connected to anything, it is just loose in the cabinet. Then we get a reset when...
