Does tough love count  ?

Made in Dex by the Author of Dex ...

The 'Typical Horn Circuit"

- Ford Horn Ciruit  (cir-uit typo -1-)
- for a ..dodge viper (car image  -2-)
- with three horns (yeah sure, typical cars have three horns. -3-)
- with a shorted relay coil (that relay never does anything -4-)
- and missing connection dots (at least 5 of em -5,6,7,8 and 9 -)
- and a switch that does nothing but connect the horns, through a resistor and a mystery box labeled 'y', to ground. -10-
- on a sheet labeled 'Horn Ciruit' (Cir-uit typo -11-)

Designed by someone appropriately named Art, initials S.M. . At least Art is happy with Dex: it fits his S.M. tendencies to a dot.
So there is at least one known customer that uses it...

And all this at revision 1:8 .

At this rate we're going to need 64 bit integers for revision numbers , before we get this one error-free.
Maybe we should use floating point numbers as DEX is really good with em. The zero: zero coordinate can be represented in at least three incorrect ways. All close to, but not quite, zero.

Love and kisses.

I have fixed example that comes with DEX. It is meant as an example to show you the type of graphics you can do and not to be an actual real car diagram.

S1 is not doing much. nothing at all to be exactly.
try connecting the swich between the VCC and the relay coil, and the other side of the coil to the Ground.

Yep. The relay winding can not be energised without a current source.
The switch must be in series with a branch from battery red and the other side of the relay to GND.
