Here we are,Velleman do three kits,  K8015,  MK111 and VM141 all with adjustable start, pause, restart functions, all available in North America, I think they would be more suited than a 528t.  I'm sure sometime I've built and used an MK111 for this purpose.

i also have a simple circuit design you could use if interested. it uses 2 NE555U IC's and two adjustable pots to control the timing of the pulses and the duration of each pulse.

C1 and C2 are used in conjuction with the adjustable resistors to control U1 and U2. U1 controls how often the pulses happen and U2 controls how long each pulse is. with this setup you can run up to a 20amp load.
