Soldered 0805 vs 0603 vs 0402 vs 0201 vs 01005 vs 008004 today :)
Howardlong:
I did a video of soldering up a complete circuit from beginning to end with a 0.4mm BGA package, and 0201 and 01005 passives, including the good, the bad, and the downright ugly. I need to remember to stop drinking a pint of coffee before doing this stuff!

Edit: this is my first attempt at a multi-camera setup, which kicks in at 07:20 after an introduction. I was running four cameras, and switched between them all in post. It definitely adds a lot of time for editing.
Pedro147:
Wow thanks a lot Howardlong I for one appreciate you taking the time to do this.
Just about to sit down and watch your handiwork. It is going to be good :popcorn:
ElektroQuark:
A lot of time but a lot of fun too.
I have three videos on my Youtube channel right now (just started), but I'm really considering a multi-camera setup, even a multi-angle setup.
Howardlong:
Rather than doing the switching completely manually, I have a multicam plugin that comes with the software I use (Powerdirector) which supports up to four cameras. I can't particularly say one way or another whether this software is any better than any other software, as the only other video editing I've ever done is with Moviemaker.
The plugin allows me to select up to four media files, and allows you to sync them all up in the plug in by a number of means, I use an audio analysis. You can then compare and choose a default audio channel. You then play all four channels together, selecting which camera view you want with the mouse or the number keys 1, 2, 3, 4 corresponding to the camera view in "real time", but you can also go back and change. This is obviously far faster than having to completely manually edit dozens if not hundreds of separate clips.
On playback I noticed that some of the focussing isn't quite right, so I need to pay more attention to that next time. Getting a decent image through the camera port of the microscope is tedious, as it requires fine and repeated adjustment, and is of course co-dependent with the eye piece focus which is what I'm seeing.
Three of the cameras I use have a half hour cut off, so I have to remember to take a break to re-start recording. Thankfully I did remember!
One of the cameras will do 4k/50p, and you can pretty easily tell from the video which one that is. The other cameras will also do 4K but only at 25fps. I prefer 50fps, I find it's smoother, so I run them in 1080p, all with a shutter speed of 1/100th across all cameras to reduce motion blur. I also ran some of the cameras with the "ex tele conv" which crops the frame to native pixel-for-pixel resolution increasing zoom without deteriorating quality.
There's a lot to learn.

** Be careful, there's fakes out that are made in China; they're easy to spot as the last I looked, they were going for ~$6 per pair (Vetus?). To put this in perspective, the genuine Swiss made Regina ~$30+ per pair.

Besides the price, what should one be on the look out for to detect the fakes?
Are they total crap, just the best of el-cheap'o tweezers - or are they actually usable in a pinch?
Thanks
