Voltlog #296 – Microscope Camera Focus Issue Fixed!

Welcome to a new Voltlog, as you may remember in Voltlog #282 I got a new trinocular microscope and then in Voltlog #292 I got a new camera because the one shipped with the microscope had issues. Banggood till this day did not replace the camera which I believe is defective, they kept asking me to try these various settings in the camera menu to improve the brightness but none worked.

Now to get a good image and have both the camera in focus and the eyepieces you will need some kind of reduction, an optical adapter between the camera and the microscope port. So first I got this SZMCTV 0.3X adapter, after reading some reviews who were claiming this will give the best field of view.

After installing this adapter I noticed the field of view was almost the same as through the eyepiece which is great but I couldn’t get it in perfect focus with the limited adjustment available on the adapter and I was getting this tunnel vision which I couldn’t quite explain but it was obviously not what you want to see.

And so I got this newer wide body 0.5 adapter and installed it on my microscope and the problem was solved I could now get my camera into focus at the same time with the eye pieces but with a loss in the field of view due to the 0.5x adapter. Getting the SZMCTV 0.5X adapter would probably also work, that’s a bit cheaper, but I went with the recommendation of getting the newer type of adapter with better optics.

Voltlog #294 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. Before I get started I’m gonna take a second to remind you to subscribe to the channel and hit the bell notification icon because that’s the only way you will know for sure when I upload new videos. 

Depending on which part of the world you live in, you might be dealing with the same isolation measures as I am, the government is recommending we stay inside as much as possible here in Romania, to avoid contact with other people. So that gives me more time to work on projects, learn new stuff and of course discover and order stuff from the internet.

I’m gonna start with this notebook which has a retro looking leather cover, I think it’s quite neat looking, I’m not sure if this is real leather or not, description just said leather. I always keep a notebook around the workbench, it can be useful for drafting a quick schematic, some dimensions or just for writing down some measurements. Another cool feature of this notebook is the binder style clips you have inside, which allow you to insert or remove paper and what’s even nicer is that you can find this type of paper with different grid styles and they’re very affordable.

Voltlog #292 – Hayear Full HD 34MP Microscope Camera Review HY-1139

Welcome to a new Voltlog, you might recognize this, the trinocular microscope which I reviewed in Voltlog #282, it’s a great tool to have especially if you start to feel your eyesight is getting weaker but also if you have good eyesight you can’t possibly solder 0402 passives comfortably or you can’t spot very small problems on soldering joints without something like this.

However I had an issue with the camera, the image is too black and so far there has been no solution provided by Banggood but I am still in contact with them and they’ve told me they are working with the supplier to find a solution but due to the whole Coronavirus (COVID-19) issue, there’s been delays.

So I’ve asked them to send another camera for review, it’s a Hayear branded microscope camera, it’s capable of up to 2K at 30fps and 1080P at 60fps, it has HDMI and USB 2.0 output as well as SD card storage support. The USB output is capable of 1080P at 30fps but that’s okay, cause I will be using this on it’s HDMI output on the 1080p 60fps setting.

Voltlog #282 – Did I get a trinocular microscope for micro-soldering and inspection?

Welcome to a new Voltlog, to save you from waiting, the short answer is yes, I did get a microscope for the lab but before I show you the microscope let’s talk about why I got a microscope and why you might want one. If you are occasionally soldering boards, electronic kits, mostly through hole components or even surface mount down to 0603 and you have good eyesight, then chances are, you don’t need such a microscope, I’ve been doing that for years.

On the other hand, if you want to be able to solder surface mount components smaller than 0603 comfortably or you want to do board level repairs on modern gadgets like smartphones and laptops, then you most definitely need a microscope as it will massively improve the quality of your soldering and the general repair process at your bench. 

Voltlog #268 – RaspberryPi 10 Inch IPS HDMI Monitor 2560×1600 2K

Welcome to a new Voltlog, it’s product review time again, this time we’re taking a closer look at a 10 inch monitor with hdmi input. This is the box it comes in, the monitor has a resolution of 2560×1600, that’s about 2K resolution in the scheme of things, 300 pixels per inch density, 16:10 aspect ratio which I’m a fan of. My desktop monitor is also 16:10 and it works so much better for everyday activities but especially if you are doing any CAD design work. It’s an IPS panel so we should have good brightness, contrast and colors, it’s rated at 400 candela per sq meter. We also get built-in speakers and the HDMI supports video & audio so you should be able to get video and sound through the HDMI cable and that’s useful because we have built-in speakers on the monitor itself.
