DRSSTC PCB pack release includes UD2.9 skip pulse gerbers
« on: May 15, 2018, 03:30:24 AM »
Hello,

I am releasing the DRSSTC PCB pack.  This includes the UD2.9 skip pulse gerbers, as well as PCBs for interrupters and bridge boards.  These boards are all less than 10 by 10 cm and so can be made for $5 from many PCB houses (not including shipping).  If you get many boards made at once, you can spread the cost of the shipping over these boards.

Boards included:

1)   UD2.9 skip pulse
2)   UD2.7 conventional board (without skip pulse)
3)   UD3.1 that uses the PSoC5 CYC8KIT
4)   Half Bridge with 2 transistors and a place for a capacitive divider for the other side of the bridge, and a place for RC snubbers on each transistor
5)   Half Bridge with 8 transistors (4 on each LO/HI side)
6)   Full bridge with 4 transistors and a place for RC snubbers on each transistor
7)   Full Bridge with 8 transistors (2 on each LO/HI side, two half bridges)
8)   Burst interrupter with external triggering
9)   AC line interrupter, includes a spot for the ATTINY85 to implement the OneTesla tiny USB interrupter.

These are all made with kicad, so you can modify them as you need to (kicad is open source software).

Thank you for the massive contribution. looking forward to see what coils people (myself included) will build with this release.

Thank you Dan!

I envy the amount of work you can get done in little time :)

I will share this on my facebook page for kaizer power electronics.

Hello,

I made a small change to the PCB pack.  The burst interrupter now includes the MIDI USB interrupter as well, for those who don't want to have to try my experimental interrupter to get the MIDI USB capability.  Of course, you don't have to add the chip to the board if you don't want it.  If you get a AVR ISP you can plug it into the interrupter board and program the ATTINY85 chip and have a combination burst/standard/audio triggered/MIDI interrupter that should be good for all kinds of stuff.

The revised DRSSTC PCB pack is attached.

Corrected versions of DRSSTC pcb pack

Hello,

I have a new version of the PCB pack with some minor fixes.

1.   I built the UD3 driver, but I found that some of the components get in the way of plugging the USB into the target board, so I moved around some of the components to allow for better access to the usb connector.

2.  I built the line interrupter.   It works, but I had to tweak a couple of component values.  It is possible that interrupting on the AC could cause a lot of noise for other devices on the circuit.  However, it does seem that it allows for more power to be drawn, perhaps indicating a better power factor.  This requires more study.

3.  The two interrupters contain a USB MIDI interrupter on them that may be optionally populated if you want a combined test/sound/MIDI interrupter.  I have included the compiled project so that the ATTINY85 microcontroller can be programmed, including source code because the code is open source.  It required a few tweaks and updates to work on more modern versions of avr-gcc, which is one reason why I included it.  The fuse bits on the ATTINY85 have to be set as given in the flashing.txt file, and then you can program the microcontroller, both using avrdude.
