HC4046 VCO Spice Model Updated
The HC4046 VCO Model on my website has been updated with a behavioral version (the device-level version is still included). You can find it at... HC4046_VCO.zip on the Device Models & Subcircuits Page...
 
Paparazzi drones
I suspect that little more than a dish antenna and a spark plug is required to over-ride the radio control of these things. The use of these will piss off nearby TV users but not as much as a shotgun...

Step-down transformer backward?
I have this transformer: model M4L-2-10, 210/230/250 primary with 115 secondary. Is it safe to use it in reverse to get 230v from 115 mains? This is in N. America. Thanks.
