Folks, the fellow in Cuba who designed the single-sided board sent me the GERBER files, etc. I have posted then in the "files" section of this group in a file called "UBitx files from Cuba".

Just a few thoughts on Dexter's wire length suggestion. ? A simple manufacturing jig is one way around this, one for each Toroid?version with a different number of turns. ?In basic terms, think about a sheet of wood, about A4 size, the working line will be the centre. ? At the top you need a holder for the wire, I assume you are using reels, so it needs to be able to rotate with some resistance, so the wires not too slack. ?So a spindle with a crude slipping clutch, a sprung material covered portion of the spindle support would suffice. A little lower down, you will need a guide ?support for the wire, it has to be at the wire working height above the board, nothing complicated, something like a closed cup hook, like the ones used on net curtails, screwed into a support above the board, This will act as a first guide for the wire. Next a bit below the hook a further guide for the wire, a small funnel, again nothing complicated, how about the top of a washing up bottle, drill the correct sized hold in another piece of wood and glue it in. Then a clamp, one of the toggle clamps used on test jigs etc. ?just to hold the wire firmly while winding. Some distance below needs to be a measuring edge, again another length of wood across the board, more on this later. Then the working point, a bit down again to give working clearance, about the distance you need the lead lengths to be I've used all sorts, the cap of a ball point to a simple pencil, anything similar to what your currently using . Next another measuring edge, below the first by the length required for winding a lead length. ?On both the measuring points you will need a marking point, something like a small headed tack or panel pin to distinctly mark the measuring point. Setup, open the clamp, place the wire roll on the spindle, tighten the retaining nut, ?run the wire through the first cup hook then through the funnel (bottle top) and under the clamp leave enough to reach the first (upper) measuring point. Close the clamp, the jig is now ready to operate. Operation. Open the clamp, pull the wire down to the second (lower) marking point, close the clamp. Wind the toroid until there's only enough wire left to reach the first (upper) measuring point. ?Cut the wire, hopefully job done. You may need to adjust the measuring points according to the number of turns on the toroid. You can use anything to hand to make something like this, you must have some ladies that are better than others at winding, use them to test your idea to make sure it doesn't slow them down ?too much. I hope this gives you some ideas and helps you to retain the services of you ladies, and enable us all the order a uBitx sooner. |

Always subject to human error.
I would prefer to have all the information so that I can make my own (and make my own mistakes). Or I can repair an error myself. That's part of being a home-brewer, which is the general purpose of all of Farhan's rigs. Make and measure. That's the process. I think the schematic contains all the relevant information. If not, ask for that, not for industrial change on a large scale. Of course, good suggestions are always welcome, especially mods that work to fix a problem. Hi. john AD5YE |

At great risk again, ...from what Farhan has said in the past and now, the wanted staff for this job to be youngish Indian girls. And they most likely have no job experience. And as girls, that don't have experience with these kinds of things, let alone, what to do with them.
He has already worked long and hard to teach them how to make the parts.. Such as they do. But from the sound of it , My comparison, it's like working with the mentally handicapped people. And I have worked with them. Telling or teaching them to do their job differently now is usually very difficult,? It's difficult to say that one of these is, just like the other, without being offencive, or playing it too cool and losing most of the message. The point is , is that he has a problem with job training his workers. And has to be creative ?with teaching and using a jigs for fool proof product making. He really has his work cut out for him. It's too bad you can't borrow smarter girls to work in the BITX shop? |

You opening line is politically incorrect, use the word employees.

As I remember these employees are from another factory that closed down. They will have some experience. I will recommend Farhan to use toroid winding machines operated by these employees. I am sure less issues will crop up! Raj At 11/08/2017, you wrote:

One could use more professional people. It would just drive the costs up. At the moment, things are not so bad on the bitx40. It is just a matter of training people. I have a belief : if you produce a challenge for people, they do step up to it. It is just that one has to 'debug' the production, find out the troublemaking points, sort them out by checklists, simple tests, etc. measure and fix. that's the mantra. - f On Fri, Aug 11, 2017 at 1:11 PM, Raj vu2zap <rajendrakumargg@...> wrote: You opening line is politically incorrect, use the word employees. |

handicapped if he tried?

If the person who wrote this would like to think back a few years ago he would realize that at one point in his life he had great difficulty tying his shoelaces (similar to winding a toroid) until someone (probably a woman) took the time effort and trouble to teach him how to do so.?
