Hi, have a well-known problem: After changing from the built-in CAN radio, my radio immediately presents itself with loss of ignition plus. E.g. in front of railway barriers a problem: When the engine is switched off, but also when restarting the radio sets a restart. So I am looking for a follow-up circuit. One that gives the radio the turn-on plus again from the duration plus, as long as the ignition plus is on. If ignition plus is off, the radio should still be supplied about 20-30 seconds, then then nic There are a lot of funny circuits, but does someone have one at hand, which also works under the disgusting board network conditions for electronicians? Mostly one from eBay or from China – building yourself is often not worthwhile at the prices. (Alternatively, an analog or with Atmel controller, I would have it all there.)
