Today we are taking a look at this old network equipment, it’s a Nokia IP330 Firewall. This router / firewall was released probably in 2000 or something similar, I couldn’t find any exact info on the release date but we can safely assume it’s at least 15 years old

Today we are taking a look at this SilverCrest USB charger that LIDL had on offer the past week here in Romania. I think it was sold for approximately 3.5 EUR which is not bad value for money if this turns out to be a safe to use charger.
Today we are taking a look at this soldering station which I got from Taobao (Chinese Ebay). This unit is fully contained, power supply is built-in, it works with T12 Hakko tips and it has a nice 1.3 inch OLED display. It’s powered by the STM32 microcontroller which should make it easy to hack if anyone is interested.
This USB charger is sold very cheap on GearBest.com and a viewer suggested I should get one and do a teardown to check the safety aspects. So I got one, and it looks decent inside, however clearly built down to a cost.
This is the new 2016 revision of the Gopher CPS-3205C. Gopher has addressed some of the issues I found in the old revision and sent me their latest for review. You will see a teardown as well as various tests performed on this power supply.
In this video I’m opening the Fluke 77 I scored at a recent auction to show and repair a small issue it has. One of the MOV (metal oxide varistor) in the input protection circuit had suffered damage probably while protecting the rest of the circuit when a HV signal was applied to it’s input, so I decided to replace the MOV.
The original MOV part number is V910LSX1399 specs: 910V 10% 1mA
The replacement MOV part number is Panasonic ERZV10D911 specs 910V 1mA
In this video I am showing various techniques I use for desoldering and salvaging electronic components like: inductors, tantalum capacitors, connectors, ceramic capacitors, op-amps, comparators, switches, battery connectors, dc jacks, mosfets, fuses and ferrite beads from old motherboards.
I am also taking a look at some laptop optical drivers and lcd pannels to see if there is anything usefull we can save before taking them to the recycling bin.
Here are links to some tools you can use for desoldering jobs:
