Hello!
im doing a project, where im making my own flashlight. Because it is a quite powerfull one and eveything is getting hot i used watercooling to cool everything down.
i designed a analogue circuit that shuts the light off when the temperatures are getting to hot or the battery is to low.
the light, and waterpump are turned on and off by a switch. now, when i turn off the light, the waterpump stops pumping inmediatelly. What i prefer is that the pump still pumps for approx 10 seconds, while the light is off to cool the light down better.
does somebody has an idea on how to manage this 'delay' with just analogue electronics?
with kind regards,
WVDW
