So, this week it is autumn break for the schools here. I've been working a bit less this week, and took the opportunity to finish a project that me and Middle Boy have been discussing, the
First Stomp Box. This one's a really easy one, just a switch and a LED in a 1590 style box. Its purpose is to switch from clean to lead channel on his guitar amp; the LED is simply in series with the switch and indicates "Lead channel" when lit.
TE used:
- Originally, to debug the interface0, my Fluke 27.
- To make certain I did not solder the switch wrong, and also got the LED the right way; the 8060.
Both meters of course are older than he is, and were chosen for being close by when we wanted to debug this. I think they suffice.
Footnote 0: The vendor, German brand Hughes & Kettner, sells the same style stomper, but call the function that one can light up a LED using the current that'll flow when you short the logic input to ground, "phantom" -- a description I take issue with, because it is not. A "phantom voltage" will exist in a circuit in a way that is independent from its usual current flow. Here, it is the same current that lights the LED and drives the input low, and therefore, it can't be a "phantom voltage".
