Today I tried ripping off the +5V trace under the pin (on the PWR IN microUSB), and it still has continuity. So I'm pretty sure there's a rabbit right under where the pin is, going into the board. I tried to lift the pin, but the soldering iron doesn't quite get it hot enough. Also it's hard to get ...

Depends, you could perhaps in software change some GPIOs used, but some (e.g. power) will not be able to be changed. You could watch some de-soldering videos on YouTube to see if it's feasible in your case to remove the header and re-install it (or a new one). Or keep that Zero as is, and get a new ...

The Raspberry Pi is very much more powerful than the Arduino in many respects. So you are not going to add much "power" to the Raspberry Pi. Think of it as, the Raspberry Pi is like the computer in a tablet, while the Arduino is like the computer in a smart thermostat. You can certainly do projects ...

Discovered this similar forum post. Slightly different goal, same idea. No resolution though.

I looked at the Zero W power components with a strong magnifying glass, and compared to the schematic, and a few measurements with multimeter. If the USB PWR IN jack is down, the 2306KE chip is above it, that's the power chip. It has four capacitors in a line, left to right, which seem to be C8 (1.8...

I have soldered tiny stuff at work. We have a USB microscope, fine tip soldering iron, etc. What I'm most concerned with, is where is the best place to do it? Is there a specific resistor/capacitor I could disconnect? (I can't find a specific schematic for the Zero W.) I don't really see the trace c...

The micro lipo charger only charges. The PowerBoost 500 only provides 5V power at 500mA (no charging). The PowerBoost 1000 provides the same 5V power at 1000mA (no charging). The PowerBoost 500C and 1000C provide charging in addition to their regular feature (of providing 5V power from a 3.7V batter...

I have a Zero W and an Adafruit PowerBoost 1000C. I want to use the PowerBoost with a battery to power the Pi (and charge it) but I want to use the original PWR IN microusb on the Pi, instead of the microusb power in on the PowerBoost. That is, I want power to go from the power supply to the Pi powe...

It has been years since Mac was PowerPC, and before that it was Motorola 68030 (later used in Palm Pilot).

I have v1 of the PiTFT 3.5 resistive touch screen and have been playing with getting it working with RetroPie 4.3. These days, the RetroPie image has the overlay so you just need to add the dtoverlay line to /boot/config.txt and get fbcp running (the Adafruit setup script does this fine). I have fou...

The command line (terminal) is running a thing called bash which is a type of shell; it's a program you use to run other programs, it's how you interact with the system. Bash knows nothing about GPIOs. The commands you are trying to run (import etc.) are not bash/system commands, they are python com...

For IDE, recently, I'm liking Visual Studio Code. It's a lighter, electron-based editor, like atom.io or Sublime Text, but with better debugging functionality.

You can install it on Raspberry Pi. Then install a C++ extension for it.

Instructions etc. here: https://code.headmelted.com/

OK I missed some pages of this thread, I'll read more. Thanks!

Check the kernel logs (dmesg) and also see if there are any Alexa logs (in /var/log, if not, try to run Alexa on a command line somehow, preferably with args that say to be "verbose"). Sorry I don't have Alexa running to say how to do this. Good luck.

I'll probably make a dash cam some day eventually. If I do, I'll make a guide.

You just want to collect data and feed it out through USB? I'd suggest Arduino, output as CSV text over the USB serial connection. On the host side (whatever PC you're using), read the CSV over the USB serial connection and do with it what you wish. You can also get fancier and send simple commands ...

I touch type too, I know what you mean. Search for VNC clients for Unity, see if anyone has one that works on your phone (i.e. not just Windows). If so, then it's easy, just use Unity to make the app. If not, find a VNC client that has an API you can use to grab the remote desktop image. Then use th...

For touch screen, you can use something like https://www.adafruit.com/product/1770 . There are others that are bigger or smaller. You want the "PiTFT" ones (not the others that work with Arduino etc.). It will plug onto the Pi like a HAT, you'll install the display software (or use the provide OS im...

When you figure it out, be sure to let us know what the problem was, and how you solved it. Good luck.

As for what is I2C... it's a very simple serial protocol using only two wires. One is a clock (signal voltage goes up and down) and the other is data (up or down during a clock signal to be counted as a 0 or 1 binary digit). E.g. you can use it to communicate to a sensor, or an Arduino microcontroll...

Unfortunately I have not yet installed Alexa. Easiest would be to get a USB mic that works. You'll eventually need one. In the meantime, ensure your audio works. Go here and test that basic sound works without Alexa. https://www.raspberrypi.org/documentation/usage/audio/ Presumably it will work then...

I want to do something similar, but as a dash cam (recording forward as I drive).

You could add yourself to be notified when new stock arrives. That controller is not as good quality as the BUFFALO/iBUFFALO brand controllers. The dark area is just a sticker (not plastic) and the buttons are likely mushy. If you just want a bluetooth controller, try the 8Bitdo SNES30 wireless game...

You can definitely connect 7 buttons to GPIOs (pins on the Raspberry Pi) and write code (e.g. Python) to read them. I imagine it should be possible to have that code run in the background, and switch emulators when it detects a button press.
