Yikes! Never would have guessed from your usual placid appearance, there was a blood-sport fellow lurking inside
Only lurking from the side as well, I can handle high voltage and currents, but I have no desire to take a two-hand sword to my neck
Also I finally found a cheap barebone bluetooth amplifier for my work shop that is actually work listening to.
I wanted a small Bluetooth amplifier for my work shop and bought some cheap bare-board versions from Ebay. This TDA7498 design is over-advertised, but not as bad as other cheap bluetooth amplifiers from ebay.
Test, frequency response and THD+n measurements show how good it compares to the promised performance of the TDA7498 datasheet.

In a celebration of reaching 10,000 subscribers on Youtube, I blew up some pieces of wire with my 2500uF / 2kV Maxwell energy discharge capacitor storing 4kJ of energy.
I also started a new dedicated slow motion video channel, please subscribe if you like to see more non-electronics videos recorded at high speeds:

Congrats sir! I don't know who is updating our resources list these days, but I will check around to see what's up.
I have 8 of these Hicon 6800uF @ 250v but stringing all them in series for 2 KJ is too scary for me!
Teardown of a Nokia Siemens Networks Flexi Multiradio base station. This have been in service as a 3 antenna system for mobile telecommunications. GSM/EDGE, WCDMA/HSPA and LTE capable. 3x70 Watt output power.

A couple of Eurasian blue tit (Cyanistes caeruleus) nested outside my work shop in one of our many bird boxes, put up to attract birds to our garden. A good 3 or 4 weeks went on with day in-and-out feeding of the young before the left the nest a week ago.
Teardowns on the inside of the workshop, new life on the outside

There is a huge difference from the very cheap 8x8 pixel thermal cameras, to the 32x32 and up to the 160x120++. The price seems to quadruple with the pixel count. In this video I am testing the HTi HT02D Thermal camera that I was able to get at 100$ on offer. This is not a paid/non-paid advertisement, my own money, test and conclusion.
Best bet to find these at a decent price is to run through ebay and send off a lot of "make offer" of 100$ on the 150-200$ auctions. But is it worth it? Lets find out!
I came by a discarded full size Dell PowerEdge M1000E server rack. Full SAN, 2 large blade servers, 4 or 6 backbone switches, all power supplies and fans. This is a system that is about 8-10 years old and had a new price of around 1000000 DKR (166666 $US).
It was all unloaded in a big mess into a container and I only had time/space to take a blade server, all power supplies and fans with me. Hard disks all go to destruction and backbone switches and the M1000E cabinet itself is too big and clumsy to have any real value in the work shop.
In the light of the Jordan Pier youtube channel being deleted/closed down without warning, with cryptic message from youtube and it got wide attention from Dave at EEVBlog, Clive at bigclivedotcom and originally from Shango066, I would like to remind you that I am uploading all my videos at LBRY as well. Please consider signing up on LBRY and subscribing there as well.

A guide on how to make the, HP DPS-800GB Rev. A, server power supply run outside of its server enclosure.
A simple bridge between pin 31 and 34 is required and it is important to NOT drill holes through the GND and +12VDC output pads, this will risk short-circuiting the output as its a 4-layer PCB.
This is 9! 12V/7A server fans built into a fan cluster with handles! It is time to wreck some havoc and play with fire and smoke!
I did not realize just how much fire was sucked through the fans until after I saw the photage. As seen in the pictures on the forum link there was some bad damage to the fan blade and wiring. It actually short circuited the DC rails from the fence melting through the insulation. It is also very good at cleaning the work shop floor.

The old rotten and leaking workshop wall and door appeared to be installed on top of an even older rotted wall. It was time to do it properly, I broke everything down and built a new wall with fiber cement, insulation and some proper wood panels on the inside.

Grieg - In the Hall of the Mountain King, on a Musical Tesla Coil
This is a teardown video of a 5 zone induction stove with a total power consumption of about 10 kW.
The induction stove is built up on standard 2-zone modules that are likely used in their 1,2,3,4 and 5 zone models, so just mix and match to get the number of zones needed. For a single zone induction zone, a 2-zone PCB is used and only one of the power electronics sections are populated, all control electronics is still in place.

Your rendition of Weezer/Buddy Holly sounds just like it did in when it was included in Win95 played through the only speakers we could find at the time.
This thread always seems to pop up as target for spammers, I wonder why?
