It’s not a marvel of engineering. It doesn’t light-up blue. It’s not as nice as the push-button anti-spark, or similar (out of stock) on Enertion.
It’s also not $45-60.
This might be a bit remedial for some of you (you know who you are), but i wanted to show how i built one in case someone else wants to make their own. You can do it easier/simpler, but i had some time to fiddle in the garage and enjoyed making it for my next build.
Starting off with the anti-spark XT-90:
I took some 12/2 wire i had laying around and the copper ground wire works perfectly to bridge the contacts for the loop.
I like modular. If it ever fails or i want to do something differently i can easily swap it out without cutting it out.
The slot is so i can squeeze it to better fit/solder.
Finished with some heatshrink and paracord so i can easily pull to disconnect.
Only issue i can imagine is depth to fit. I will likely turn it flat and secure the bottom down. I might also attach a small cord/wire to the paracord loop to prevent it from getting lost.
Nothing too special, but i think it turned out well. I plan to install on my new e-Omen (ongoing slowly).
Hope it helps!
