| Yet another resistance decade box |

| Dave:
I forgot to mention that the similarity to the Aperture Laboratories logo is strictly coincidental. ;D You could remove those direction selection jumpers on the bottom and reduce the size of the board slightly. It doesn't matter which way the current flows through a resistor. |
| Fortran:
@Dave - In order to avoid lawsuits, this too was strictly coincidental ;D Made it for my nephew. It's a "lights and sound thingamajig(tm)". |
| PeterZ:
I etched a small test pcb today to check if the make-before-break operation of the switch. I used the continuity tester to check if there is a short beep when the switch passes from one setting to another. Result: yes, it does work. I think i will make two versions of the board: one as in original: break-before-make and the new make-before-brake, maybe a few versions of a small 5x5cm panel (sort of), consisting MBB only, BBM only and MBB+BMM versions. |

Subbed, just in case there is a group buy, count me in. |
