Bee Venom Collector

[Papaflesas]

Hello,

I am still a freshman in electrical engineering, so I know a bit more than the basics, but I have to create a device for some personal use.
I want to make a bee venom collector.
From what I know this device delivers an electric square pulse every few seconds and stops after a 45-minute period.
The pulse is then transfered in a panel made out of steel.( The photo below present it in brief detail ).

Some other chatacteristics are:
Power: 11 - 15V battery or power adapter.
Output voltage to collector frames: AC 15 - 40V (adj.)
Output frequency: 300 - 4500 Hz ( (adj.)
Consumption: 80 mA.
Reverse voltage protection.

I have heard that is not that hard to be made, thus I am still a rookie in circuits.I would really appreciate your help.

A diode will be adequate to provide reverse voltage protection.
I do not understand the output requirement. Either it has an ouput frequency or a pulse every few seconds. A microprocessor could give the frequency and duration times.
A 555 or 4093 can make a simple oscillator to drive a pair of fets at the required frequency.
You will need a freshman in electrical engineering to design a transformer. A ferrite core is probably suitable, I use TV line output transformer cores for much higher powered cases.
Output voltage variation would be easier done by switching transformer taps.

Alright, I will try to do it with the 555 . Thanks
