Voltlog #115 – Pure Sine Wave Inverter Circuit Waveforms

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.

Voltlog #113 – 300W Pure Sine Wave Inverter Review & Teardown

Today we are taking a look at a 300W pure sine wave inverter which was provided for free by banggood.com for the purpose of this video. First we take a look at it’s output on the oscilloscope and then we continue with a teardown of the inverter.

Voltlog #28 – InTheMail

In this episode I am showing my latest mail items which include: a bunch of Vishay-Dale shunt resistors which I got for a bargain price, different sizes silicone wires, ultrasonic sensors, a voice recorder, the st-link v2 programmer/debugger, dmx512 decoder board for driving rgb leds, rs485 to ttl converter module, a pair of 433MHz ASK transceivers, some thermal plaster, a metal marking/punch tool and a hiking monocular.

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.
