Title: KPE - www.kaizerpowerelectronics.dk (see latest post for new videoes)
Post by: madsbarnkob on April 03, 2017, 07:56:02 am
Hello All

Just wanted to tell you a little about my high voltage, Tesla coil and general electronics website. 8 years of projects and data :)

It contains schematics, pictures, instructions and videos of 10 Tesla coils of different topologies, a DRSSTC design guide on how to chose components for building such coils. Another 10 smaller high voltage related projects, 3 tube amplifiers, many online electronics calculators like IGBT gate drive, transistor base resistor, MMC calculator and single layer coils. Theory pages with data lists, file archive with a good collection of application notes. General electronics and everyday experiments.

A new article has been added that describes the thoughts, design, construction and test of a very high impedance primary circuit QCW DRSSTC, where the voltage ramp is coming straight from half wave rectified mains supply and a mains synced interrupter is used to trigger at the right interval.

The article covers the fall pits and strange behaviour of Tesla coils driven in this manner.

The project is highly experimental and the results were not as satisfying as expected, but problems with switching transients was a much bigger issues than initially thought of.

Read it all, see all the pictures and view all the videos at: https://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iv/ (https://kaizerpowerelectronics.dk/tesla-coils/kaizer-drsstc-iv/)

It's better now, but since you asked, I'll put in my 2-cents... You look a little rigid and need to loosen-up a bit. Also, stop looking up to your right before cutting forward. Fasten your eyes and maybe experiment to see how a brief mischievous eye works for your style (you may not be comfortable with that so try what works for you - but be sure to hold the eyes till the first cut).

Since HV is kind of risky and exiting stuff, a continuity of background beat music is catchy (volume and edge should suite you not anyone else). Raise and lower background volume to not compete with voice-overs and effects. Since it's short, make sure cuts are fast with some light-flash cuts and definitely in-sync with the rhythm. Maybe some help here (https://www.videomaker.com/community/forums/topic/cut-to-beat-vs-against-the-beat).

Lastly you may want to cut down, break-up or even lower the long spark sound at the beginning, since noisy intro's get old pretty quick when returning to the channel (but it could be just me the semi-retired schlager musik fan).

Thank you for the feedback.

I know I am a little stiff in it, I think it comes from English being my 2nd language and maybe a little stage freight, handheld camera as I do not even have space for a tripod in the cramped lab :) So I spend too much brainpower on keeping camera still enough, to keep my head in the shot etc etc. I never make a script beforehand, I do retake some scenes, I often feel the big disadvantage of being alone to do both experiments and filming, its hard to do both really good.

I do try to be more happy, less dry in my speech and so on, but damn its hard when it gets technical :)

Problem with music and youtube is that they will almost instantly slam you with a copyright claim, so I just stopped using it, maybe once I build my sequencer/VCOs I can make my own, but it will hardly be any good. Even royalty free music / commercial free music does not go free of this.

I made that splash screen with spark sound as my trademark, as you have seen on many videos, lowering the sound and shortening it to 2 seconds will be tried in the future.

I have been working on getting better audio (external active microphone on DSLR), unless its handheld smartphone recordings and lightning, but a 10 sq.m. lab that contains 9 sq.m stuff really makes things difficult, but I do not want to let that stop me from making videos :)

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. 3x90 Watt output power.

https://www.youtube.com/watch?v=nL69J6KHYRE (https://www.youtube.com/watch?v=nL69J6KHYRE)

Flexi RF Module Triple (FXxx)

The Flexi Multiradio Radio Frequency Module (FXxx) or RF Module, is a 3-branch multicarrier,multi-standard radio transceiver module. The module consists of three independent branches, capable of transmitting and receiving signals of multiple radio technologies concurrently:

    Up to 6 GSM carriers with 400 KHz minimum carrier separation
    Up to 4 WCDMA carriers with 4.6 MHz minimum carrier separation
    Multi-carrier LTE signal with 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, and 35 MHz carrier bandwidth
    Multi RAT operation with combination of GSM, WCDMA, and LTE

The RF Modules FXDA, FXDJ, FXEA, FXCA, and FXFA/ FXFB are referred to as 70W RF Module variants. RF Modules FXEB and FXDB are referred to as 90 W RF Module variants. Each branch consists of a transmitter and two receiver chains. FXxA and FXFB (70W) variants have front end software tunable filters (STuF). 90 W RF Module variants have fixed full band filters. FXxx is a 3U high module with an integrated, replaceable 3-fan assembly for module cooling. The supported functions are:

    Chaining up to three RF Modules with OBSAI RP3_01
    2-way receive diversity in the receiver chains
    Integrated antenna line supervision
    MHA, Antenna Hopping, EGPRS2, and VAMOS support
    Digital and control circuitry, optical interface, DC/DC power conversion, and other necessary functionalities
    Integrated DC line OVP, Class II rated to 5kA pulse (FXFB, FXDB/FXEB)
    Remote Electrical Tilt (RET) support (FXFB, FXDB/FXEB)

Flexi Multiradio BTS GSM/EDGE modules are equipped with an integrated air guide plate providing full thermal compliance without casings. This allows installation of the modules without casings in Flexi cabinets and enclosed 19″ racks. Casings and covers are recommended in standalone 19″ racks (no cabinet) for safety reasons. Casings are not part of the FXxx delivery package. If the configuration requires casings, Flexi BTS Module Casing (EMHA) kits must be ordered.

The Flexi Multiradio RF Module variants are:
Version    Description
FXDA     GSM 900 (E-GSM) 70W
FXDJ     GSM 900 J-Band (P-GSM for CDMA co-siting) 70W
FXEA     GSM 1800 70W
FXCA     GSM 850 70W
FXFA/FXFB GSM 1900 70W
FXDB     GSM 900 (E-GSM) 90W
FXEB     GSM 1800 90W

- Guesstimate the internal resistance of a unknown meter
- Design custom scales if you have a blank meter or want to use a meter for another purpose than its original.

The HP T-620 Thin Client is a powerful little machine, that with ease can be hacked into using a random 19VDC PSU and run Windows as any normal PC, easy and cheap PC!

This thin client was thrown out, without anything else than the box itself, no power supplies, no nothing.

https://www.youtube.com/watch?v=d0CsY1bC3pI (https://www.youtube.com/watch?v=d0CsY1bC3pI)

The port and connector layout from the manual shows that the HP T-620 models needs a 19VDC power supply. A little searching showed that it was not as simple as just supplying it with 19VDC. HP has put in a few tricks to make a "smart laptop charger" so that you can only use their chargers.

The "smart laptop charger" restriction can be bypassed with a simple current limiting hack as per this little schematics. All credits for this hack goes to:  http://nerdipedia.com/wiki/tiki-index.php?page=Smart+laptop+charger (http://nerdipedia.com/wiki/tiki-index.php?page=Smart+laptop+charger)

Post by: madsbarnkob on December 08, 2019, 12:36:33 pm
This is a Aethra Colour CCD #Webcam that was part of a system made for remote #medical diagnose / consultation for patients in remote locations.

The system was mounted in a car to be mobile, so a driver could visit patients and make a call to the doctor do complete the consultation within the patients home. The system was driven by a #embedded PC with a complete circuit for the interface, audio/video and running all peripherals on a RS232 daisy chain. The whole setup used some kind of GSM link to transfer the video and audio signal, seemed to be a very expensive and complex setup.

I don't see that reed relay as lasting too long.. maybe when it got stuck they would kick the box to make it work for a while longer. I wonder if that isolation transfo would have reqired litz wire? Also, nice outro music - Cheers! and Happy New Year!

Title: DSO138, Not Even Once
Post by: madsbarnkob on January 20, 2020, 10:21:31 am
Before you buy a DSO138 or DSO150 from ebay, amazon, wish or aliexpress, it is important to understand what you are getting. The specifications are very loosely written and what looks good on paper is useless in practical use. Here I test the DSO138 specified at 200 kHz, but in reality it is worthless above 20 kHz.

Buying the right oscilloscope is knowing your work area limits and where it might be in the future. I recommend that you read: 12 things to consider when choosing an oscilloscope: https://www.mouser.com/pdfdocs/Tektronix12_things_to_consider1.pdf (https://www.mouser.com/pdfdocs/Tektronix12_things_to_consider1.pdf)

This is the first upgrade for the Anet A8 3D printer. A new powersupply from a HP server will be a fire-hazard reducing upgrade compared to the original undersized and over-specified power supply that came with the printer.

12V @ 62A is of cause much more powerful that needed for the printer, but this will keep the fan spinning at minimum speed. You do not want to be in the same room as a server power supply running at full current output with maximum fan spin. It is like a jet engine.

This is part 2 of my #diy #led flood light that is going to be used for high speed video filming with the FPS1000HD camera. It should be able to deliver around 20000-25000 Lumen.

Here I modify 3x HP server power supplies to deliver 36VDC, add fan controllers for the heat sinks and box it all up in a "very compact" box that can be handheld.

This is part 3 of my DIY LED flood light that is going to be used for high speed video filming with the FPS1000HD camera.

In this video the lux value is measured to 25000 at 1 square meter which corresponds to the given lumen value for the LED COBs.

The 36VDC power supply ripple is examined, the 50 Hz ripple is limited to around 1VDC and the high frequency 20-45 kHz switching noise is no apparent problem.

There is some flicker in the background when recording at 1000 and 4000 FPS, but once it gets up to 8000 and 20000 FPS, there is not enough light to even get the subject properly lit up.

I prefer to put it on the ground and crawl into, I think it is homemade and made from a large gauge wire or one that was used in full contact medieval combat sports, would explain why it was ripped and thrown out. That is a pretty violent sport. I recorded some fights in a tournament back in 2016, crazy people coming out with concussions and broken arms/legs etc.

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  :scared:

Also I finally found a cheap barebone bluetooth amplifier for my work shop that is actually work listening to.  :-BROKE

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.

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!

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.

This is a teardown video of a 5 zone induction stove with a total power consumption of about 10 kW.

https://www.youtube.com/watch?v=G-GHxlLsCy8 (https://www.youtube.com/watch?v=G-GHxlLsCy8)

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.

All pictures of details can be seen at: https://highvoltageforum.net/index.php?topic=1270.0 (https://highvoltageforum.net/index.php?topic=1270.0)

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.

Good question I've reported a few lately. Mads runs highvoltageforum, so one wonders if the problem there is un-contained?

Interesting  :-// we did talk in pm about a certain user making trouble before, with all kinds of bs reporting and anti-spam threats, any coincidences there?

I got very little problems with spammers on www.highvoltageforum.net (http://www.highvoltageforum.net) it has only been the usual Russian IP accounts that has been effectively stopped with bans, came from a few single sources, so was easy to get that sorted.

My 2021 New Year resolution is to do annual battery checks on all my battery powered instruments. I found batteries as old as 13 years over expiration date that had also started to leak, but much less defective batteries than expected.

Thank you for following Kaizer Power Electroncis in 2020. See'ya next year!

2000 kg (4395 lb) would be the weight of the AC motor that this 630 A / 440 kW contactor can turn on and off. This also explains the shear size of this contactor, a almost solid piece of metals, copper coil, iron core, copper terminals, platinum contact points and aluminium enclosure.

Building large flight cases and transport boxes is easy and much cheaper than buying them. Hinges, locks, fittings and aluminum rails is readily available at almost all audio / light retailers of equipment for disco, clubs and festivals. I share the tips on how to construct it in a simple way and make sure you get parallel edges that looks good when the boxes are locked together. With so many different rails, hinges and locking mechanisms it is easy to make a mistake and mount something off-center or with distances that does not take aluminum rail thickness into account. The stencil template, I show how I made in another video How To Make a Stencil For Spray Paint With Cheap Hand Tools (https://kaizerpowerelectronics.dk/technology/how-to-make-a-stencil-for-spray-paint-with-cheap-hand-tools/)

In this video I show you how I built 3 boxes in total at a cost of around 300$, two very large flight cases for my secondary coil and topload. The third box is a cable and equipment box that is just made from the leftover plywood from the two large cases.
