For me, the first time I saw one that started to look like it could actually be useful, was when the Andonstar A1 arrived on my work bench: finally an affordable and reasonably stable microscope that you could connect to a PC via USB, so that you could manipulate and inspect your circuit boards and soldering workmanship. Quite quickly this manufacturer followed up with models that had a built-in LCD, which removed the necessity (partially) of a connection to a computer: an enormous improvement. With every new addition to the Andonstar family that has progressively become available, a few things were changed, added and improved – you would expect that by now a point has been reached at which a new model is little more than ‘more of the same’. There are already four different models in the Elektor Store, and there is now the next version: the Andonstar AD407. What changes has the manufacturer made that justifies the existence of number five? Regarding the implementation and price, this new microscope is closest to its predecessor, the ADSM302, and for this reason the characteristics and specifications of the AD407 are compared to this model and the other models are not considered here. Image display and storage When you put the two microscopes side-by-side (Figure 1), the difference in screen size is immediately obvious. The screen diagonal for the LCD of the new model is more than 5 cm (2") bigger, which is an enormous improvement. While in most cases it was reasonably comfortable to work with the 5” screen of the older model, in our lab we nevertheless connected an external 10” monitor via HDMI for the more detailed fine work. Figure 1. The Andonstar AD407 (right) next to its (slightly) smaller sibling. When it comes to the image quality, the already limited documentation from Andonstar is somewhat vague. According to the manufacturer, the AD407 has a 4-megapixel sensor, while the ADSM302 doesn't get any further than 3 megapixels.

Review: Andonstar AD407 Microscope Review: Andonstar AD407 Microscope For some time now, cheap USB devices have been available that are pitched as ‘microscopes’, but the early models were really too flimsy for practical use in the electronics lab, while the focus distance was generally too small to be able to solder under it. So for that fine-pitch soldering work (SMD) you needed to make do with a magnifying glass (lamp) or reading glasses, other optical aids were either unusable or not affordable. microscope when unpacking and writing this review. In normal use of the microscope (and in our lab that means ‘soldering and/or checking of solder joints’) the remote has no additional value, in my opinion. Furthermore, the AD407 contains a hex wrench for assembling the stand and – according to the manual — a UV filter. The latter was missing from the microscope that I received for this review, but to be honest, I cannot immediately think of an application for it. Then remains the question: if you already have an older Andonstar model, would you consider the purchase of the new AD407? With the A1, V160 and ADSM201 my answer will be a resounding ‘yes’, but in the case of the ADSM302 I'm a little more reserved. It is quite handy to be able to inspect an object from an angle, but: you do not necessarily need such a stand for that (you can also place the object at an angle). The large LC display of the new model finally turns it into a real stand-alone microscope. As already mentioned, in the Elektor lab we use, in many cases, a (small) additional monitor next to the ADSM302, but with the AD407 this additional clutter on the work bench becomes unnecessary. This is for me a more than sufficient reason to give a clear preference to the new Andonstar, if I were to make a new purchase. And if I already had an ADSM302, and the budget permitted it, then I would certainly replace it with an AD407.

WCastro PodeSim!, uso um fone bluetooth para ouvir musica e atender chamadas. ressalva: quanto mais coisa deixar habilitado, menos dura a bateria, bateria bem curta.
