Re: SSID for 802.11g/n network at 2.4Ghz not being seen

It had not been hidden. I spoke to someone about it, and it appears that the 2.4Ghz was turned off due to a bug that was preventing the g/n working with b turned off on the 2.4Ghz radio.

SSID for 802.11g/n network at 2.4Ghz not being seen

I have been told that 802.11b was disabled to improve performance on this SSID, but now none of my Pi Zero W's or 3's can see it. I have a 3B+, and it can see the 5Ghz band just fine. I was told that the 2.4Ghz was not disabled, and some 2.4Ghz g/n devices appear to be working just fine. I am sorry ...

Re: OTG - Pi Zero VS Pi ZeroW

Really? I've never tried OTG on my Pi Zero W, but I have had success with the Pi Zero. Only issue I've had is the DHCP/addressing/bonjour stuff, as I was doing this with the Ethernet over USB mode to a windows 10 laptop. There probably is a utility that helps, or some simple setting that takes care ...

Re: Will my setup explode or something?

I'm plugging the Pi into the extension cord which will plug into the wall, and the usb hub uses an AC power converter which will also be plugged into the extension cord. Since we are talking a Zero here, back power it off the hub. In fact, why not power everything through the hub's power supply. Ju...

Re: Pi 0 W uses for after school program

How old are the kids? Pi zero W shines in physical and embedded programing tasks. Scratch, python, some sonic pi. Things like that. Get some buttons, LED's, resistors and wires. Maybe even some cheap motor drivers and motors for some robotics.

Re: RPi B3+ powering through GPIO

Yeah, it was always "you can do it at your own risk." It would be nice if the 5v on the GPIO were protected too. Guess it wouldn't be too hard to fuse and throw a tvs across a power supply. Just been thinking it would be nice to have an alternative power supply, since it feels like usb is being push...

RPi B3+ powering through GPIO

So, I noticed the improved power management chip on the 3B+, and was wondering if there are any advantages or changes in GPIO powering the 3B+? Is it still considered an unsupported hack to do that, or since the PoE board does this anyway, is it considered "more supported" but not official?Is the 5V...

You should be able to mount /dev/sda as a fat partition. Give those parameters to mount, and see if it doesn't work just fine. I swear I used to do it all the time back in the day without a hitch.

Normally a bunch of these components are combined into a device that you need a custom enclosure or project box for. You can get project boxes easily. Maybe what you need to do is make an enc...

Re: i need help using motor driver in python

That's no enable and PWM, that's enable and direction. The motors are controlled through two pins. 0% is stop 100% is full. One is forward and zero is stop. At least, that's how the board is marked.

Yeah, the above answer is the key.
