Prototype LED Osculator - repost


I need a circuit that can blink 50 LEDs at a speed of 1Hz adjustable up to 10MHz or more.

Adjustable resolution of 1Hz steps.

LCD screen to display frequency.

Buttons or dials to adjust speed.

Perhaps 1 button for Hz, 1 button for MHz?

On/Off button or switch.

9 volt operation for prototype.

and if that works, I will need a 12 volt model with no LCD screen,

12v model should work only on a programed frequency. Not adjustable.

12v model should power 100 LEDs, in two sets of 50.

I build my own circuit board and prototype.

Please no milestone payment until prototype is working.

I have paid two Freelancers before that collect money and provide broken design that never works so I will not pay anything until this one works.

PIC chip is ok and preferred. =)

Thru hole components preferred for prototype.

SMD components are ok for resistors, transistors, diodes, capacitors, but NOT for IC or PIC.

Thru hole only for IC and PIC.
