We want someone to design and build a small electronic circuit which has following requirements 1. Time delayed relay circuit 2. Preferably operated with 9V 3. Should activate for approximately 5 seconds after every 12 hours 4. End actuator is a 9V operated dc motor (This is just for information not to be considered in scope) 5. Compact as possible (Preferably within a boundary of 50x50x30mm) 6. Should be very econimical built with basic electronic components like Micro Controller, transistors, capacitors, resistors, potentiometers) 7. Final product should be low cost as it need to cater mass production Please send your best proposals. One time design cost and recurring developement cost can be discussed

Hi, I will use small microcontroller (probably ATTiny 85), with RTC circuit to get actual time, and for relay we can use 5V activate Relay. I will use eagle to design this circuit. your board constraints is enough. I think It can be smaller. Let's discuss this over messenger. Best Regards, Rijal

My solution is to use a very small and cheap microcontroller Attiny4 with sleep-mode current as low as 0.4 uA together with a Low Quiescent Current LDO Regulator such as MIC5231. A typical 9V alkaline battery has a capacity of 550mAh so this approach will give a very long battery life (5+ years) and a very small footprint. Instead of a relay maby a N-channel MOSFET could be used :)
