Re: USB keyboard on Pi 400 desktop

Just throwing this out there.
If you are going to use a different keyboard, why not get a RPI4 8GB instead of the 400?

Re: Driveway gate notification project

Thanks ghp for that code, but I'm going to stick with mine. Upon further review of my gate controller, there is a setting that will automatically close the gate after a pre-defined amount of time. I currently have it set at 10 minutes, so my program will work to alert us when the gate opens and the ...

Re: Driveway gate notification project

OK, so I got it to work with my other RPi Zero with a female hammered header. I have the "sleep" set to 60 seconds to see if it will check again and send another email if the gate is still open, eventually it will be 300. What happens is the only way it sends another one is if I close the ...

Re: Driveway gate notification project

LED direction is correct, was able to make the circuit work while hooked directly to a 9v battery. I have modified the program to have the pulldown on pin 17, Will try my other RPiZero tonight. It also has a hammered header, so if that doesn't work, I will try it with my 3B+. If the 3B+ works, I wil...

Re: Driveway gate notification project

So, I found one problem. I'm using the hammer in header, and it appears that they are not making contact. I went as far as writing a simple script to light an LED and that didn't work. Even just hooked up the LED & resistor circuit to the 3.3v pin and a ground pin and still nothing. I have an ot...

Re: Driveway gate notification project

I originally commented out the pull-up, and it was doing the same thing.
I’m outside doing “honey do’s”, but will try again later this evening. Will also comment out the email parts and jut see if it will ptint something to the screen.
Thanks for the suggestions so far.

Re: Selling Arcade Cabinets With RetroPie

From what I have read on other threads, you can do what you like with the Pi after you purchase it. If I were to do it, I would build the cabinets, hook up the Pi, and include an instruction sheet on how to finish setting it up and get/install RetroPi, including the link to their site so they can ge...

Re: Raspberry Pi Zero W not connecting to wifi

You could try the underscore _ instead of a space. Why? When the problem is the unicode quotes rather than plain ASCII quotes. The SSID still needs to be in quote marks. I was unaware that there are different type of quotes available, as there is only 1 key for them on any keyboard I have ever used...

Re: Overclocking RetroPie vs Raspberry Pi OS

Thanks jahboater ,

I just wanted to make sure the change was by OS and not something that was permanently changed on the board itself.
Don't really do anything in RPIOS yet that needs the overclock.

Thanks again.

Overclocking RetroPie vs Raspberry Pi OS

Hi All, I've never done any kind of overclocking before, but might try. On my RPI 3b+ using Raspberry PI OS, I haven't had a need to, but some of the games on my RetroPie build get a bit laggy. Both RetroPie and RPIOS are up to date. If I overclock while using RetroPie, does it stay in place when I ...

Re: Knowing weather a gate is open or closed

Our sensors aren't anything that "drastic". The ones I'm considering are basically a couple of NO or NC reed switches epoxied into a small housing that are actuated by an external magnet. In a safety system these run to a relay which controls all the rest of the safety measures, alarms, co...

Not using “switches” per say. My company make sensors for safety systems, many that are used in the food industry, that are waterproof. The sensors have reed switches in them that are actuated by a corresponding magnet. When the gate is closed, the magnet and sensor will be by each other, closing th...

That’s kind of my plan, the sensor anyhow. We have a lot of sensors that are reed switches. Just need to get the correct actuator (magnet) to “cross” the gap.
