@@scraplawless5693 Have played it already but not on this coil. A bigger one. My DRSSTC I

@@latenightprojects ight

@@patrik2749 ?

for the UD2.7 driver the output is the same as the incomming powersupply which is 24VDC. if the GDT ratio is 1:1 then the output of the GDT will be around +-24V. That under no load tho and under load it does decrease. While it is over your igbts rated voltage it still should be fine tho do add tvs diode on the gate and maybe one or 2 less turns on the secondary of GDT. It is such a high voltage on the output bc its needed to turn igbts on faster and fully and necesery for igbt bricks or igbts with high gate charge.

High pressure

That's just how it be

When its turned on it the first thing it does is calubration. First turn on its full cal and every next time you turn it on it does quick cal

Thank you!

Why so?

@@latenightprojects Just the rhythms and notes that aren't right but I still like the video so whatever

@thebeaverkidd2970 I see, I will try to improve that. Tho it may just be bc I'm limited to 2 notes at a time with the DRSSTC. Am working on a new interupter which should sound better.

@@latenightprojects Hey it’s chillin bc it’s still cool to watch regardless.

DIY one tesla sd interupter based interupter

You can set it to sync to a NPT time server everytime you turn it on and then in periodic intervals. You do need to connect it to WiFi or lan for that but it works well

@@latenightprojects Ok cool didn't knew, but still you shouldn't have to do that on a scope so that was a real surprise.

@@dtiydr yea true although afaik basically all the scopes are like that. Atleast all the ones I've used

@@latenightprojects I have a few little older handheld ones and they are not like that, had and old Tektronics and that was not like that either. Guess they have just ignored that in in modern scopes which is messed up since it would be so extremely easy for them to fix.

@dtiydr for handheld ones it makes sense as the battery is always in it and there's no psu that's getting switched off. Should have clarified that all the other scopes I've used that even had a clock option were modern digital scopes.

Yes, it is a very good deal for the price. Very usefull tool. So glad i didnt cheap out when buying my first scope.

I got them from DigiKey. You can also get the HFBR-2412 and HFBR-1414. Or a cheap alternative is the toslink transmiters and receivers.

now I put everything on board, but before i plugged it in, i tested the 24VDC between + and - and it beeps and shows 0.3 ohms. I don't know if that's a problem...

@edicizmak4229 hmmm that is a problem. You have a short somewhere. Second though is that it's only short for a short while untill the caps charge but 0.3ohm is even too low for that. So very likely that u have a short

Is there a tutorial to follow to upgrade to 200Mhz? I am considering to buy this scope as well

ALL THE AMPSSS!!!

Sure, lmk what exactly do you want me to send you. Might be better if you email me.

@@latenightprojects never mind dude.. I've already got what I needed from Alexandre Creuz. Though you have replied to me way very late, thanks anyway dude.

Yea ik abt the arcs striking nails and possibly starting fires. After noticing that they did i ran a ground wire down that wall to minimise that risk. And yes the driver board is good.

Glad you like them!

Yea sure ill do a video testing the driver. I have also designed my own smd version of the UD2.9 driver with poor-mans pulse skip so am waiting for parts and then will test it in my DRSSTC.

Thanks! It took a while to build and solve problems along the way. Still not completely problem free but works super well for a first DRSSTC. Had to up the power a lot after changing the cap bank which in turn is causing some heating issues so ill have to find a way to solve those. The OCD tunning wasnt too hard, i first aproximatly calculated the peak primary current and set the ocd close to it. Currently its around 1kA. Its twice what i originally designed everything for lol. But yea i must say without a scope id be having a lot of dead igbt bricks.

Hope 2 CU soon with a new video on how to scope your drsstc b4 powering it.

Yeah its a very nice scope with many features.

With foam you can get an even surface. Might be hard to do that with just paper and glue. Sounds like it would be pretty fragile and pain in the ass to add tape

yes

Then whole bank is rated up to 800VDC but in the shown clip it was charged to just 565VDC. Capacitance is 880uF

If you have an isolation trafo, you could put the primary and secondary in series to get 460VAC or 650VDC. You can also chain a bunch of other trafos in series with that to get basically whatever voltage you want.

Yea i uploaded some short vids i filmed while my friend was visiting me. And i have few long form vids i still need to edit

Lol yea. Tho my workshop is in a house and my neighbors are like 50 or so meters away

Yea it is the same desk. Tho the black stuff was impressive to fully remove because it had burned pretty deep into the table top

@@latenightprojects Oh wow

Yes, my old workbench top lol

@@latenightprojects Great. What voltage is this and how much current does it pull?

@@TantalumPolytope voltage I estimate to be around 10-20kv. Current not sure, will need to measure
