This is a followup video on the 300W pure sine wave inverter I reviewed a couple of weeks ago. A couple of people we’re curious how the output mosfets are switched in order to obtain that nice looking sine wave on the output.

Voltlog #114 – Aneng AN8008 Probably The Best $25 Multimeter
Today we are taking a look at the ANENG AN8008 multimeter. This product was sent to me by banggood.com free of charge for the purpose of this review. They also sent me an ESD mat, because I have two benches in here in only one of them had an ESD mat so I needed a second one.
There is also a newer model, the AN8009 which I also reviewed, you can read about it here.

In this InTheMail segment I receive the HP 3478A 5.5 digit multimeter, a Probe Master 8028s test lead set, the Anker Astro E3 10000mAh portable battery charger and the Seagate Expansion 2TB external storage hard drive.
VoltLog #8 – Kit Assembly 0-30V 0-3A Adjustable Linear Power Supply
In this video I am assembling a 0-30V 0-3A Adjustable Linear Power Supply kit. Will it work at first power on? Or will Murphy get me this time? Watch the video and see how I got myself into trouble. I also reverse engineered and got a schematic of this kit which I am showing towards the end of the video.
VoltLog #5 – HP Agilent E3611A Power Supply Teardown and Calibration
I got this HP Agilent E3611A Power Supply from ebay. It was marked as not working and I was planing a repair video on it. Unfortunately the unit turned out to be fully functional so I only did a teardown and calibration.
