Therefore, the topic of microscopes for diagnostics and soldering has long been relevant, and if the USB “fine scope” for 10-15 USD was more or less suitable for the first one, then soldering under it was extremely unpleasant. And now the vision is not the same, and the details are painfully small.
In the last photo – the inner world of K511LA3 – could not resist – opened it. Here it is – happiness, but no – as already rightly written, a ring illuminator is far from always good, and here I am again drilling holes for the backlight lamps on a flexible base that were in the trash. However, the "pieces of iron" came, but what to do with them? Life has become more fun – there is a button – you press it, the image is displayed from the computer, you press it again – from the microscope. And so, after reading the review, I ordered the same set for myself. Not very pretty, but in general, almost perfect for my "pieces of iron" The solution is simple – I ordered an inexpensive KVM- a switch with a minimum of functions, USB. < /p> We modify a little with a file, drill holes and cut threads for fixing screws, and the microscope is ready. Personally, this is convenient for me, despite the more "cool" and less cheap ones suggested in the comments models.
(The photo is already protected from “scratches”, when trying to insert it somewhere.) At the same time, in the upper position, and, accordingly, the optimal, as it seems to me, magnification for soldering, from the object to the objective lens is 220 mm. I got it in this form I found parts https://jiji.co.tz/55-formal-shoes/formal from several MBS microscopes, but the assembly I needed was missing everywhere, and then a work colleague told me about attempts to make a drilling machine from the remains of MBS-9 … I wanted to immediately throw away the incandescent lamps and firmly insert home-made ones from 3 1-watt diodes, but the picture of the backlight with incandescent lamps seemed interesting, so for now I refrained from breaking the lamp sockets – I will make diode ones on the same base. So, the first task is solved, however, there is not enough space on the table for 2 monitors, and it is lazy to switch connectors many times, and it is not useful for their long and healthy life.

Another implementation of the Eakins microscope

I have complained more than once about my age and vision – in my youth, doing amateur radio (that was the name of the “nerd” occupation with a soldering iron and the Radio magazine in my hands), I practically didn’t use a magnifying glass, but now … Satisfaction is complete, on a 19" monitor there is an excellent picture, without any delays when moving. The microscope itself, the lens and the illuminator are considered in great detail in the review, therefore, in order not to tire the reader, I will not repeat myself. In other things, in my youth, surface mounting there was practically none, and probably the smallest thing that needed to be seen was the value of the resistor 0.125W.
In general, I persuaded him … Who cares how it ended – read on, however, the final version – in the title photo I went to the garage, found my old photographic enlarger, and realized that it was neither for me nor someone else will not come in handy – the roller drive is completely "eaten" by corrosion.
