I'd like to boost 12 volts to 24 volts at a few milliamps using minimal
circuit board space. Regulation is not important, so I thought of
using this
12v

1K R R 1K +->|-+---,

| \/ | |__ --- |
\c /\ c/ | | |
|----' '----| | | load
/e e\ | | |
| | | | |
'----------------+------'----'---'
|
gnd
with equivalent values for the timing caps and resistors giving 50%
duty cycle for a nominal 24 volts out.
Any other ideas or suggestions...?
