Putting a Line Voltage Multimeter in a Receptacle Box (VA4K vs Shogun Test)

Video

  By Scott • 2016-10-03 ,

I got a Volt/Amp/Watt/Wh Meter from Banggood and wanted to put it to some use. So I decided to stick it in the back of a receptacle box, making some kind of metered extension cord.

This video shows the process of doing that, but is also a test of the Blackmagic Video Assist 4K vs. the Atomos Shogun for a review I’m working on. It’s a literal side-by-side comparison of the two. Though there’s no difference in quality (there shouldn’t be — they were both recording in ProRes HQ via SDI), I recorded about an hour of footage and neither one showed dropped frames or sync issues during that time. So far so good.

More to come on that later..

Sixteen (!) New Batteries for a 3000VA APC UPS

Video

  By Scott • 2016-02-15 ,

I recently got a good deal on a 120V 3000VA APC SURTA3000XL, a 120 pound beast of a double conversion online UPS which boasts over 30 mins of runtime at half load (and that’s still over 1000 Watts)! It didn’t come with batteries, so this video shows the process of “refurbishing” a couple of old modules with new batteries, and testing out the UPS.

The reason I was hunting down reasonably priced DCO UPS wasn’t because I’m especially concerned about poor-quality power from my wall, but because I needed a UPS that would play nice with generator power.

I’d love to be able to afford a couple of ~7500 Watt inverter style generators (one primary and one backup) to run the whole house during a power failure, but the best I can do is a pair of contractor style gensets. They’re noisy and output a mess of voltages and frequencies, but they work. Well, they didn’t work with line interactive UPSes, but they’ll work fine with something like this APC.

Bullsh*t Product – Defiant 6-Outlet Metal Surge Protector from Home Depot

Video

  By Scott • 2015-09-24 , ,

Apparently I was so distressed by the non-metal “metal” Defiant power strip from Home Depot that I made a video about it.

If you hate videos but love text, then mosey on over to my previous post about this travesty of a product, and follow my adventures getting pissed off about their HDX Whatever Something Light.

Home Depot: Review Rejected – HDX 150-Watt Incandescent Clamp Light

  By Scott • 2015-04-14 ,
HDX 150-Watt Incandescent Clamp Light Model CE-300PDQ - Hyperbolically Aflame

The Rejected Review I know that I tend to be harsh in my criticisms, but this is the most recent review that I tried to post to Home Depot’s site regarding their HDX 150-Watt Incandescent Clamp Light CE-300PDQ: Very rarely do I wish I could give a product a negative number of stars, but this is one of them. I know that for under ten bucks I shouldn’t expect an extremely high-quality, durable item. I know that at this price the light could fall apart completely after a bit of use and it wouldn’t be a huge deal. But what it absolutely shouldn’t do is cause a fire, which is what TWO out of the SIX of these I own … Continue reading

Chevy Volt Metered Charging (Phase I)

Chevy Volt 120V Charger Mounted on the Wall

My wife and I recently brought home a brand new Chevy Volt (named “Sparky“), the plug-in electric hybrid vehicle (PHEV) from Chevrolet.  It’s a really cool car, and you can read about our first experiences with it here. Of course, the whole point point behind a PHEV is the actual plugging in.  The Volt comes with a 120V charger that plugs into your average 15A receptacle, and can fully charge the car in about 10 hours. Chevrolet’s charging station partner, SPX, sells a variety of Level 2 charging stations compatible with the Volt (and most plug-in electric vehicles, including the Nissan Leaf).  The Level 2 charging stations use 240V, and can charge the Volt in about 4 hours.  We’re going to be … Continue reading

Garage Subpanel with EMT

  By Scott • 2009-06-08 , ,

I have a 1 car attached garage (about 25×12) that I’ve been using for various projects. I’ve been wanting to upgrade the electrical since I moved in about 7 months ago, and I figured I’d do it in EMT. It’s rather stupid because the wall I’m installing most of the conduit on is adjacent to the house — however it’s framed separately, and there is a ~2″ gap between the back of the framing and the side of the house. It would make a perfect wiring chase for NM-B, making the job a hell of a lot cheaper and easier. But I wanted EMT because, well, for fun. It looks cool too. This is the first project I’ve ever piped … Continue reading
