Removing insulation from fine wires

JOHN CRONHELM <johncronhelm@...>
 

My wire stripper won't strip these small digital and audio wires. I used a sharp blade around the circumference of insulation but very labour intensive.
Any better ideas?

Re: Hijacked: C vs C++

Hi Jerry:

I've seen statements like this:

    It's always been straight C (K&R or ANSII) if I want to code for speed or size

many times before, but I've never seen any a priori proof of this or articles that discuss it. It seems that it would make sense to be so, but I don't know if that's pushed into the generated code or if it's an increased load on the parser given the semantics of C++ versus C. Some even say that, because C++ uses templates in the libraries, the code generator can perform more optimizations on the code because it "knows" what you are doing (What are the fundamental differences between C and C++?).


I don't have an answer, but I do try to follow the goals of C++ where it makes sense, especially encapsulation. If anyone has a definitive answer, I'd really like to know about it.

If anybody want's to pick apart my use of USAish or my C indentation style (or lack thereof), have at it.

It's always been straight C (K&R or ANSII) if I want to code for speed or size,
and for the last couple decades I've been resorting to Python for easy coding. 
This violates my primary beef above, I do try not to be overly pendantic.

A more thorough explanation, then:
"their" is possessional - it's the plural of "his/her/its"
"there" is positional - in this case the position/place is in the code and eventually on screen.
They sound the same but have vastly different meanings. This is partly American dialect and partly sub-standard education - not your fault, but your teachers in childhood and the system they operate in. It's akin to "your/you're" and even "yaw", and that dreadful "y'all". Really, don't get me started ... do 100 centers make a dollarer? and where the 'ell is the "L" in sodder and goff?
Better?

The BITX group includes persons for whom English is not a primary language.  It also includes
English speakers form all over the world who speak one of more of the many English dialects.
This results in deliberate or accidental use and abuse of the language.  It probably serves us best 
to allow a little flexibility in how we spell and speak any of the languages used here. 

Topic of this thread is "Nextion 3.2 Display"  and not how the language is being used, unless of
course it refers to C-language and coding for the Nextion Display operation and interface.

p.s., Allen: I'm not an English major either, just a kid who listened and learned. Our school leaving qualifications were School Certificate and University Entrance. In S.C a pass in English of 50% was mandatory. I managed 70%, and that was my 'failing subject', the lowest in the subjects I took and omitted when aggregated for the final 'Pass Mark'.

I've used one like the picture below for years.  I think I picked it up at Harbor Freight for a few bucks with a coupon.  I had always heard it was an awful tool but figured I would give it a try.  After a little adjusting it has been by go to for small gauge wire ever since.  I think Harbor Freight is US only but you could probably find something similar at Canadian Tire or your favorite purveyor of Chinesium finery.

I have an old pair of strippers I keep around for fine wires.  They are like these:


You adjust a sliding screw to set the size so they are not as convenient for stripping “regular” size wires but they can be adjusted for any size wire up to their maximum size.

Re: Removing insulation from fine wires

Rob Snow
 

I use my teeth.  I gave up trying to find a pair of strippers that would strip the insulation while not taking a few of a braid with it.  If it's really hard insulation, I'll score it first.

I'm sure this is not recommended.

I placed a photo of my 3.5 Nextion, CECs firmware 1.094. It is installed and running on a Ubitx version 3.Nextion has a list of 3d bezels for each size with downloadable stl files. I ordered a 3.5 bezel from 3d Hubs and it cost me $10. I think it looks pretty good on the face of my rig enclosure.

I can vouch for the size increase with C++.  When I was teaching C and just getting my feet wet with C++, we did a direct comparison.  The results showed a 1.5K executable for C and 80K for C++ with the exact same code, simply renaming it .C++ instead of .C.  It is due to the libraries being pulled in.  Speed is a different issue since it is highly dependent on coding style.

I kinda cheated... my 20x2 LCD was mounted above the Lexan, so I repurposed some of the holes and left the others there.

Re: Removing insulation from fine wires

Brian L. Davis
 

I've always used a small pen knife kept very sharp.  It takes a while but you can feel the difference between the insulation and the wire underneath.
I just hold the wire and roll it with my thumb against the blade to strip the insulation off.
The only problem comes when you get a different knife, I've nicked my thumb more than once with a new knife I wasn't used to.

Re: experience with Sunil VU3SUA's enclosures #ubitx

Mark M
 

In my experience, he's more likely to respond on Facebook. He posts there in the uBitx groups now and then. I had ordered a case in late March and shortly thereafter he announced a couple new colors in a FB posting. I sent him a message via FB about changing to one of the newer colors and he was very willing to switch. He had inventory in the color I wanted (blue with white panels) and sent it out right away. I had several FB messages with him. You might give that a try if you're on FB.

OTOH, a friend of mine ordered a case shortly after I did and has still not received it and has had no response to several email inquiries. He is planning to file a complaint with Paypal.

As for the case itself, it's well done. You might want to remove some of the paint from various places to be sure you get good contact all around. I think some of the connectors could be higher quality and the off/on switch failed after only a few uses. I also had to adjust the position of the board so that the display would line up with opening...I elongated the four holes about 2mm to the right (looking at it from the front). Overall, it's probably worth the money, esp. if you don't want to do a lot of drilling & filing & acquisition of connectors, etc.

From some postings on FB, it looks like he's working on a version to handle the touch screen displays.
