Re: Removing insulation from fine wires

Robert Alexander
 

Those are great for stripping or cutting. I used one for 30 years for stripping wires of almost any gauge.

I use these for CAT5 wires for the breadboard, and 30 AWG wire wrapping wire. There is a sliding screw nut that the opposing side hits against to set the depth of cut for repeated stripping of the same size wire. And I use a velcro strap to kinda hold the handles partly together, otherwise they spring out far apart. Or you could look for strippers that also strips 30 AWG. They have about 6 small wire sizes on those, and they are almost never in a store, you have to order them.

It isn't a voltage doubler. You need a second cap for a doubler. The Diode to ground keeps the load symmetrical (more or less) for positive and negative excursions. There is no need to double the voltage, there is plenty of voltage and current available to light an LED.

I have the Nextion 3.2 (non enhanced) display working with my uBITX, but the screen is not fully utilized.  The file I used is ubitx_32.tft.  Will an updated .tft file for the 3.2 display be available at some point?

Thanks to all who have made this great little rig available to the amateur community - your hard work is appreciated!

It's clean and concise and powerful, I get far fewer coding errors than when writing in C/C++.
If there are time critical functions to implement, write them in C and call them from the main python program.

That's how I started (IBM 370/168) but it was a bit more than 40 yr ago. After a while I got into cooler stuff like Pascal, a little FORTRAN on PDP 11's, assembler on various microprocessors, then C under various flavors of unix on minis & micros, C++ and finally Java on various platforms. Java is pretty cool but has gotten pretty bloated. C is still the best, IMO. I like to write code but don't seem to have the patience for it any more. It might be different if I was still getting paid for it. :) I can really appreciate the time & effort you guys put into it.

Talk about bringing back memories!

I learned on a 300baud teletype in high school - my school was the second in the nation (so I understand) to offer computer programming, and I took it the second year it was offered.  We had access to the school system's mainframe through the teletype.  We also got introduced to our first computer game - "Star Trek".

Then I progressed to Fortran on punch cards.  And waited for the (hopefully thin) stack of printout.  (For those who don't understand, if you did the job right, you got a very thin stack of fanfold paper.  If you made a mistake in your programming, you got a big pile with all of the messages and errors caused by your mistake.)

Back on Topic - I'd wondered why Arduino code seemed familiar and why I had little problem figuring out the routines I needed.  I'd studied C on my own several years ago.

I started with a 110 baud teletype (also in high school).  We learned BASIC on it.  Once I learned ‘C’ I never went back to BASIC.

I don’t recall getting reams of paper due to Fortran errors.  I remember that you could get a very large stack of paper if you botched the first character (carriage control).  It would feed the paper at maximum speed and only the CARRIAGE STOP button would stop it.  It was always something to see the operator come flying out of their seat to reach over the printer and blindly slap the CARRIAGE STOP button (inconveniently located on the other side of the printer).

Re: Hijacked: C vs C++

When I was attending USF back in the 70s, the system and four mainframe printers (the old ultra-high-speed drum printers) were in the room where we submitted our punch card stacks.  They routinely had several huge packing-crate boxed of tractor-feed paper behind each printer - all connected together, and it would print out a page (lots of text) in a couple of seconds or so.  One day I saw one of the funniest sights I've ever seen connected to computers - somehow all four printers had been put into full page-feed mode.  The paper was flying vertically out of the top of the printer and hitting the ceiling above it (all four printers), first it would pile up against the ceiling and then fall forward, then backward.  The sysop for that day was in the back of the room running around in a little circle while shouting "Turn it off!  Turn it off!!! Turn it off!!!" - and although they had everything shut down in less than a minute - the area behind the counter was waist deep in loose printer paper.  It took them (as I remember) at least a day to get everything cleaned up and back in operation.  (We had to come back a few days later with our cards.)

I had one of those printers, along with a mainframe given to me several years ago, but could never find the right adapter or terminal to use them... and the Florida humidity got to them and ruined them.  I forget all the specs now, but it had for it's day a huge hard drive, a fast high-capacity platter drive, and SCSI connectivity (except you couldn't program through the SCSI port).
