well everything discussed here was enough for me (does not know much about electronics) to finished building my version of the minibrute. And just look how it turned out! =)
this of course does not imply that you wont stumble upon any other difficulties but thats why this form exists. To help people!

Well i know something in electronics but anyway double check of everything is needed.
Your coil works very good. Just a question, what is the current limit there?

Hi Austin,
Congratulations on the DRSSTC. Nice to see it running indeed!
One little thing in video, watch the garage door opener above the coil.
I blew the receiver on mine once with a DRSSTC.
May want to move the coil over a few feet so not directly under the opener……
Rgs, Ch
As for your coils they are inspiration how beautiful you make it. Usually personal projects i just lash-up, rarely make it pretty. And now i will try to make something similar to your coils :)

If you send me your address, i'll be happy to send you a new 1.6 ohm resistor.
Is it possible for me to buy one Fairrite 5978006401 from you? Shipping&handling included on my cost. I almost found all parts but fairrite does not have this part number and i dont want to pay company shipping and custom tax from company for 1 core. Ultra will stock me with TVS and im ready to go
Second i did list of errors mentioned in this thread. All builders can help to fix what i mistaken, and help Dr. Shock in next revisions.
Collection of errors found within parts list, schematics and book.
1. C101 decoupling capacitor
This capacitor is not located on bridge board, however oprating without it will blow the IGBT-s. You will need to add it "manually"
2. c32 exists in schematics but not on the board. Its needed to solder this capacitor on board
3. Note: put the current transformers on the output of the H-bridge, not between the MMC. This is not an error, just a reminder
4. c32 not on board. Add manually
5. r28 needs to be OPEN - reminder
6. C81 should be soldered directly on the temperature sensor
7. Unamrked capacitor in top left of board. By EVR:
Yes, this was kind of an optional capacitor. Just as an energy storage reservoir. Not really needed, but if you put it in there, its not going to hurt anything. Just helps supply energy to any bypass caps during switching. these capacitors are typically rated at least 10x the combined bypass capacitance on the board.
8.Swithces on advanced modulator DPDT instead of DPST
9. When setting the current meter, you need to disconnect one lead of the 1.6 ohm resistor. This is an error in the instructions.

My goal is too keep all the wiring at the bottom of the base. under the heat sink. Keeping it in place with aluminum tape. As for the display board, I ordered a 36" ribbon cable for the connections. I wanted to have access to the pots on the control board.

Can I get some opinions on this layout.
Looks good, but like Ultra7 said, wow, that is definitely overkill on the heatsink.
I wanted to have access to the pots on the control board.
Aha! Good idea!

Thanks for doing this Kreso. I plan on eventually building another one, and this makes it a lot easier. I've been meaning to do this for a while, but this thread is really long. This list really sums up the key points in this thread.
