In this video I am doing a teardown of the S-993A desoldering gun to check if there are any problems with the wiring inside.
This is a short review of the S-993A 90W Desoldering Gun which was sent to me for free by banggood.com. I was planning on getting one of these for a long time and I’m happy that I finally got it, it’s very useful in repair jobs as I’m showing in the review video below.

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.
Like I mentioned I’m the first to get this board, months before the official release date, this is an engineering sample.
I was lucky to have a good friend of mine, a childhood friend, that works at the raspberry pi foundation. He is the guy that did the layout of all the raspberry pi board you know. So I was having a chat with my friend this week when he showed me this and I just didn’t let it go until he asked the right guy and finally got the approval to let me show this thing on camera.
I’m not allowed to keep it because it’s one of the few engineering samples that exist but we can take a good look at it so let’s go to the bench for a close-up.
Here are some high-res images below, please credit with link to this page if you plan to publish them anywhere.
This is a review and teardown of the LCR-TN components tester. It is a rather new model that comes in the form of tweezers and does a whole range of measurements.

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:
- CSR8635 Bluetooth 4.0 Stereo Module
- TP4056 Battery Charging and Protection Module
- 400mAh Lithium Polymer Battery
- MCP6272 op-amp
- 3.5mm Stereo Jack
- Generic ABS Plastic Enclosure
Or you can just buy a ready-made bluetooth receiver.
