Electronic – How to turn a switch on/off repeatedly in 1 minute intervals

lightpower electronicstimerwatts

I have a light bulb plugged into an outlet and I need to be able to turn it on and off again and again in 1 minute intervals for a period of 10 hours per day (a total of around 600 on/off events per day). I have found a similar question on SO here: How can I turn on and off a switch every 20 minutes?

However, besides the fact that the question was for 20 minute cycles long I saw a number of answers about micro controllers which I understand will take a lot of work and know-how to achieve.

Is there any pre-packaged solution or something that can be done easily ?

As a side note most digital timers that can be set for 1 minute increments can only be set around 7 times per day (max I found was 50 settings per day) so this isn't a viable solution.

The timer will need to withstand 500-1000 watts (if this matters).

Thanks

Couple options:

  1. Repeat cycle timer (you could find them on ebay for around $20)
  2. Digital timer (you could find them on Amazon for around $25-$50)
  3. Microcontroller (a bit tedious)
