I did some research and found out that almost every Amscope can change its work distance by adding an additional LENS on it. In my case I would need a 0.5x Barlow which decreases the magnification but increases the working distance:

I have a tendency to buy one microscope with more working distance than 100mm because the one that Im using right now is a CHEAP german microscope with 20x magnification and only 70mm working distance. It is mounted on an old TV boom stand so I can swing it everywhere on my desk. The next one I...

What do you think about Amscope SMZK-1TSX It has a working distance of 8" or 200mm

"dried up sea water" that is exactly how it looked!!! I made a quick search on eBay and in some auctions of IPA the sellers claim "for technical purpose" or "for cosmetic purpose" I never thought there were a difference since both of them are 99% pure!

It would be much easier to identify your posts when you have an avatar Maybe something like this :p Feel free to upload more examples!

This is another case where the improperly aligned MagSafe kills the OneWire circuit I cant remember any Video of Louis pointing out how important the alignment of the adapter is... It is more likely the opposite way how he handles the MagSafe in his videos when he tests boards! It looks like he...

Be careful with your measurements. On the board there are a lot of caps across CPU/GPU and GND! CPUs and GPUs appear as a very low resistance so it looks like the cap is shorted! You have to desolder the CAPs to get proper measurements. AGAIN headache :D

Witch alcohol do you use? Which brands? I tried the same way but it left white stains behind. The board looked worse than before :D I used fresh isopropyl alcohol directly of the bottle

btw which SMC chips are compatible to each other?

Nice to hear that :)

I had once a similar accident with a naked DC in board and a aftermarket charger! If you don't have the alignment of the case and you don't be careful enough you put 18V to the middle pin of the DC-in board witch is the dataline! This fries your one wire circuit as duke mentioned! In my case I...

I had a similar problem with a machine where the spongy thing on the lvds connector was shorting all the pins when the cover was on. After placing capton tape around the connector it worked!

The most parts of the motherboard (not to say all :)) are connected to this specific rail so if one of this parts is shorting to ground you won't be able to tell which one unless you realize which one gets hot. BUT PP3V42 can only handle about 250-300mA so it will take reeeeealy long something...

I've been searching for a while with no luck! I'm trying to implement the *.brd extension into windows so it opens my brd-files automatically with board view. This is what I tried: I saved boardview.exe on my local HDD -> right-click on any brd-file -> open with -> search boardview.exe -> sat a...

I used an ATX power supply before I get myself a proper bench power supply. BUT you have to be very careful where and how you inject the voltage since the 3.3V rail of the PSU delivers over 14 amps and that could blow your traces right of the board!

I remember a video where a bad tantalum cap prevented the machine to boot. If you give these broken caps some heat they will work again for a while. I don't know which section you really heated up and what temperature you used BUT maybe you should try reheating the caps first with under melting...

totally agree with you guys A BIG THANK YOU!!!

As Louis once said "you don't want to see the customer again" so be sure you tested the machine well before giving it back! ASD is the first but not the last test you should run! Speaking of ASD: I have tons of different versions of ASD and it was a pain in the butt to get them all. Nevertheless...

No Title Thank You for the reply Q5500 was the first place i looked at - I forgot to mention it Everything measures and looks fine I attached a picture so you don't need to search it your self PPBUS_G3H on the left side is already 7.6V so the outgoing signal on PIN 3 is also 7.6V The...

Hi there, I am glad to be a member of this community and here is my first post :) I managed to fix a 820-3437 Board by removing a short to ground on PP3V42. I had to replace some Caps getting very hot when I was injecting 3.4V with my bench power supply. Furthermore i had to replace the...
