I hope a native speaker can correct me :)

! Whoever really sent you that Wun-Hang-Low package deserves an honorable special mention in your next video. That was fabulous !

[nicknack]

Love the high framerate - not experiencing any blurriness or issues due to the 50fps like others are, so I don't know what's up with their situation. I'd say stick with the HFR :D

[lanimereala]

A bit of clarification on the role of the antenna on the back of the PenPad. The hybrid chip on the flat flex is the wireless communication device that is used to connect to the USPS mail truck docking system that works on a 2.4 GHz system, encryped using a special (i think 256-bit encryption) connection using WiFi, and the mail truck in turn uses the internet connection provided by one of the major US carriers to reach to a server somewhere. Hope this helps. Btw, in the mail van the dock is for 2 PenPads.

it is kind of weird how much we like these mailbag videos... its pretty much like a poor kid watching his neighbors open presents on Christmas morning through the window... knowing he's not getting a damn thing. and ENJOYING IT 0_o

[Barnacules]

I was laughing so hard when I saw the Wun Hung-Lo tear down :P

[Nostalgianerd]

After view of video, I am agree that Wun Hung Low product is very best. I go fully recommend to people I meet. Very good qualitty.

[fibrodad]

fantastic mailbag, the one hour time was brilliant, the quality was superior, the special guest openers were a welcome surprise, and the final segment was pure hilarity. thnx.

[sonicase]

impressive design from the wun hung-lo factory

5:08 one little side note.. the method of detecting ionizing radiation (e.g. Gieger counter or scintillation counter) determines what sort of radiation you're going to detect. For instance, GM is not suitable for detecting gamma-rays and x-rays due to the low efficiency 

[MasterControloriginal]

fuck 4k,  50-60 FPS are the future!

PS: framerate conversions are bad, decide what framerate you want to use and set all the cameras on that (or at least the half of that). 25 and 50 fps or 30 and 60 fps, not this 25 and 60 with a 50fps conversion.

His wife starts opening at 42:06 if anyone is interested :)

Hi Dave. In the MAVO-35 multimeter, the transformer is used for AC current measurement. It is a curent transformer and the different windings are for the different ranges. Sorry for my english! Like your blog and youtube videos. Best to you and family.

[rickbronson]

Loved the Wun Lung-Lo! Absolutely hilarious spoof! It instantly brought me back to 1968, sitting around the table with a bunch of ham radio nuts and one guy mentions "one hung low". I had no clue what he was taking about at the time.

[electrodacus]

For mailbag and similar videos where camera is stationary and there is not much movement 25 or 30fps is better because at the same encoding size there are less frames so each frame can be of higher quality.
For places where you have the cammera hand held or there is a lot of fast movement 50 or 60fps will give better result less motion blur.  

[laurancehayes]

Keep up the good work Dave... Mr Wong forgot to tell you that board was on the repair line where Mr sum ting Wong (head of diagnostics) works but it had not been repaired yet. The fault was found in testing by Mr bang flash ow when it was powered up.

[Psychlist]

Also notice Wun Hung-Lo sent the letter to Austria, not Australia. I'm going to assume it's a joke, because no one would call out a cold solder joint.

I'm really curious what the writing says now. Any translators here?

[sparkyprojects]

Love the way that D9, R12, R13 have been raised from the board for airflow, so essential for cooling

[capoman]

The Wun Hung Lo segment was amazing, just too funny. I can't believe this is real.

[illustriouschin]

The framerate was immediately noticable on my big plasma before you mentioned it.  good job buddy.
