Voltlog #120 – Mini DC Power Supply Review
So I guess a gadget like this is worth 10$ because you could replace that linear breadboard power supply with a more efficient one, which will give you voltage and current display as well as adjustable output.
Here are some images I took during the teardown of the mini power supply:

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.
