Thermal Detonator wiring diagram

I stumbled upon what looks to be the 3d source files for roman props thermal detonator. I ordered one, but it will be a while before I receive it.

I checked out this page: Proffieboard Thermal Detonator

It looks to be wired using an older board. Can you guys tell me if this wiring diagram for a v2.2 board should match up?

I changed it a little - no charge port, and added a kill switch. The battery will be removable.

Those instructions are designed for the KR/OR thermal detonator, so I am working on a new chassis that will fit the roman props.

The kill switch is not really required, as the board has a FET that kills the power completely after ~30 seconds.

I hope you know what you’re doing with the removable battery. I didn’t have the space available to make the battery removable in my design.

Thanks, how does the fet cut the power? Is that the pfet on the helper board?

I think the KR TD has a bulkier shell, hence less room.

Mine is tight, but because I am making a new chassis, I think it will work.
Here is a snip

Yes. When the cover is moved back, the switch is triggered, and that turns the power on. When the cover is moved back, some capacitors keeps the gate low for a while, but after 20-30 seconds, the power is cut.

Nice chassis, hope everything fits. :slight_smile:
Do you have the helper board at the right angle for the button?

Thanks been fun to work on. I hope it fits too. Still waiting on the TD to make sure it is the design I am working on.

Yes, I think I have it! By some miracle, when I placed it in my chassis design, it pretty much fell into place (more or less). I drew up the helper board too to make sure it all fits. The leaf switch looks tight, so I may need to work on that some how. Maybe shortening the leaf.

Been doing more designing than building lately. Hopefully that will change and I can get to this guy.

I think I had to cut mine a bit.

Design takes time, but I’d rather spend time on tweaking the design than tweaking things afterwards…

I probably need to start a build log here, but I just received my Roman Props TD, and the current chassis is exactly as expected. Looks like he revised some of the electronics, but dimensionally, I think my new design will work!

@profezzorn, I am working on the files and config, on your td page, it states to run the following command:

sox --combine=concatenate "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 22050 -p trim 0 0.3" "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 22050 -p trim 0 0.3" "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 22050 -p trim 0 0.3" -b 16 bgnarm.wav

Where/what os do you run this? I tried windows and linux, both said command not found. Poking around the web, it looks like its python?

That is a shell command. It should work on any platform that has sox installed. I would probably recommend linux.

Great, thanks!

After some stumbling around with it, I figured it out.

You need to either first ensure your source file’s sample rate is 22.05kHz, or use a 44.1kHz sound and modify the command like
sox --combine=concatenate "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 44100 -p trim 0 0.3" "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 44100 -p trim 0 0.3" "|sox clash5.wav -p trim 110s 2442s" "|sox -n -r 44100 -p trim 0 0.3" -b 16 bgnarm.wav

Although I’m curious why this works as “s” in sox means seconds, not samples.
But it works as i can see it’s using .005 seconds through .111 seconds for the grabbed snippet.

They sample rates did not match. I gave me an error. however, not knowing how to fix it, I used the included “older” files that came with the font. Do you know if there is an easy way to check the sample rate in windows?

You got me. this is the first time even hearing of this program. :grin:

I do not.
In MacOS, it’s just part of the details shown when highlighting a file in the “explorer” a.k.a. Finder window.

I suggest you download Audacity, a free audio editing tool. Just opening the file will show you the rate, but also allow you to make all kinds of edits to files, record new ones and much more.
I personally prefer version 2.4.2 because newer versions broke stuff for me.

Then you can make whatever kind of noise you want your sounds to be, including bgnarm.
Something like this comes to my mind, which i just whipped up combining and editing 2 sounds together in Audacity. Sounds from https://freesound.org/

Thanks. I have used audacity before.

Pretty cool sound you did there! What sounds on the site did you use to make it?
