HOPI-9800 Power Meter Review

I take a look at the HOPI-9800 from #Shenzhen #HOPI Electronic Technology, a meter that displays the supply Voltage and frequency (or “frequence”) as well as the Amperage draw, overall power in Watts, power factor, and annual power consumption.

It’s a somewhat dangerous contraption that’s not all that well put together. And I forgot to even mention the sketchy multi-national power socket.

The WAudio W-3900 Power Conditioner – A Surprisingly Mediocre Thing

WAudio W-3900 Power Conditioner - Cover Image - ScottDotDot

The WAudio W-3900 Power Conditioner is a well-made PDU/power strip, with a couple of bucks worth of filtering components inside. If it were sold in the $50 price range, I’d definitely recommend it for its solid build quality, decent quality components, and retro looks. But at $180, the amount of power “conditioning” (it’s really just filtering certain frequencies of noise at low levels) doesn’t justify the price, IMHO. To be fair, the product can be found on AliExpress for $137 at the time of this writing. Though the marketing materials promise “the highest level of surge & spike protection”, in reality it is not what I would call a surge or spike protector. One weak PTC thermistor is presumably the … Continue reading

Solderable LED Xmas Tree Ornament – Christmas the DIY Way

DIY Tree

I got this because it looked like a cool little project, and a neat (if tiny) gift for the missus. So that’s about the extent of my motivations. If you’re trying to put one of these together, I’m hoping that this video might answer a couple of your questions. It’s not really meant to be an educational video, though; More a demonstration of what’s involved in assembly for anyone considering a purchase. Speaking of which, if you want one you can pick one up for about 5 bucks over at banggood.com.

And in case you were wondering, this is not a paid advertisement. I actually paid them for this thing, so it’s pretty much the opposite. (If this kit were complete crap I would tell you.)

2D Version

3D Version

For viewing with Google Cardboard, Samsung Gear VR, Rift, etc.

A couple of people have rightly told me that you can just set a 3D video to 2D viewing mode, and therefore don’t need to upload 2 versions of the same video.

There are a couple of problems with simply uploading one 3D video, however:

  • Because the two sides of the video are compressed horizontally, viewing it in 2D stretches one of the “eyes” to full screen. That means it’s much lower quality with half the horizontal resolution versus a regular 2D version.
  • As far as I can see, YouTube defaults to anaglyph (red/blue) mode when browsing 3D videos on a regular monitor. That’s a potential turn-off for any viewer that doesn’t know about the switch to view it in 2D instead.

If I’m off base here, please let me know. I’m still learning this whole 3D creation process.

$10 Credit Card Sized Cellphone (Matrix Relarded)

Here’s a tiny cellphone from Aiek (your top brand for cheap-ass mini phones, maybe). I got it for $10, and surprisingly it works pretty well!

I forgot to mention in the video, but it’s GSM and definitely compatible with AT&T’s network. (I tested it using H2O Wireless, but they’re just a virtutal provider on AT&T’s system.)

You can pick one up from Banggood, but unfortunately the price has jumped up twice since I bought it, and now it’s at an unfortunate $18.47 (October 8, 2016). I’m sure it’s sold elsewhere, so hopefully you can grab it for ten bucks from another source.

The free delivery option was surprisingly fast to me here in NY at just over a week.

This definitely won’t be replacing your iPhone 7 or Google Pixel, but as a backup/emergency phone to keep in a handbag or backpack it’s pretty cool.

Etekcity “Outdoor” Collapsible “Camping” LED Lanterns of Doom

Here are some collapsible LED “camping” lanterns from Etekcity. The reason I put “camping” in quotes is because there is no sign of waterproofing on these things.

I suppose if you’re camping in the desert they’d be fine.

Wait, no they wouldn’t be. Because one out of the four didn’t work, and the soldering was abysmal. If you want to see details, I do a tear down in the video.

Let’s [Quickly] Open: AEDILYS Motorola Nexus 6 USB Dock

This is so close to being a good charging stand, except that the USB port is used to hold the phone in place!

Its design is quite simple, as it’s just a USB 2.0 pass-through from a micro-USB port on the back of the dock to a male micro-USB on the front.

There’s not much more to say about it in text, so check out the video to get a full look at it! And this does have the benefit of being one of my shortest videos, so you only need to invest about 2.5 minutes into it. :)
