Re: Wishful thinking for an additional product

I would suggest an alternate lid to the official Pi4B case that includes ventilation holes (over the DRAM package) and a small fan over the SoC. It should have a couple of female Dupont leads to plug to 5v and ground connections of the users choice. A couple of minutes with a Dremel and the $3.50 M...

Re: Image File Utilities

They're not picky about where you place them (/home/pi would be fine). You must make them executable (chmod +x ...). They could also go in ~/bin (that's /home/pi/bin ). Raspbian automatically adds ~/bin to your path at login if the folder exists. mkdir ~/bin is all people need to create it. The sys...

Since this isn't flux-core solder, it'll basically last forever. Old flux-core solder often doesn't work as well and needs liberal quantities of flux pen to make nice joints. 20/80 might've found some use for soldering valve/tube mounts, if your facility has been a recording studio for a really long...

I just added the line reading the output signal of the sensor (line in green) and it works nicely.
Oops, I forgot to put that back in. I don't have the sensor, so I had a line that created random numbers instead.

I think you need to be looking at a different platform. While the 4B is much faster than previous boards, a capable NLVE platform it'll never be. It's still basically a mobile phone without a case.

After your log.write line, add: log.flush() Python I/O is buffered, so if you break out of a with open(…) loop, the data may never get written. From the file documentation ( pydoc file to read it): | write(...) | write(str) -> None. Write string str to file. | | Note that due to buffering, flush() o...

There's always WordGrinder:

Personally, I prefer dosbox + Protext or Microsoft Word 5.5, or even Wordstar under CP/M. But those require a certain patience with fiddly emulator details.

Re: Print raw data to label printer from python2 not working as expected.

I don't think having lpr vs lp makes much difference here. I've found that cups-bsd gets installed automatically by other packages, as I've never knowingly installed it, yet it's always on my systems. I do reflexively use lpr in preference to lp, as I was a SunOS user for a very long time.
