In this video I’m gonna show you how to load a custom image on the e-paper display. Let’s see how easy it is to get started working with one of these e-paper display modules and an Arduino board.

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.

I understand there has to be some research and testing done for these fuses to meet the safety requirements but can that account for the huge price?
I’m moving to a new apartment and I have more space for the voltlog lab. Unfortunately I won’t be able to upload any videos for 1-2 weeks until I have everything setup.
In this video I am repairing a power supply board from a Samsung TV. The part number for the power supply board is MK32P5T (BN44-00213A). The TV was showing the stand-by led but refused to turn on. It turns out this was a common problem with a simple fix.

This is a behind the scenes video on how I designed and assembled the raspberry pi 4 board.
This week I build a DIY bluetooth 4.0 audio receiver. I used the CSR8635 bluetooth module, a recycled lithium battery cell that I got out of an old laptop, a TP4056 battery charging & protection IC and a DIY PCB I made myself.
Here are links to these items if you plan to build one yourself:
Or you can just buy a ready-made bluetooth receiver.
It all started a few days ago when I was talking with a friend and he suggested, since we do most of our phone charging at night, why not charge them at a lower rate for increase battery life. As you may know, when you increase the charging current, charging happens faster at the expense of losing battery life over time, you get fewer battery cycles before it starts losing its capacity.
So I decided to build this small gadget, that goes between the usb output of my charger and the usb plug from my charging cable. In my case I have an Iphone and the charging current can be limited to 500mA by having a set of resistors on the USB data lines.

In this episode I am building an analog adjustable dc load with parts easily obtainable from ebay and banggood. The advantage of such a dc load is that you can understand how it works, modify or repair it if necessary far easier than you would with a digital one. I was able to push mine up to 60W dissipation, but it is recommend to stay under 50W to protect the mosfet.
Here is a list with links to the parts used in this project:
