Quoted from Butch2099:
I would buy a few that ran off the flashers. I also can't believe nobody has made them. There seems to be enough demand
So I was planning to wait until we were further along to make an announcement but after seeing this thread I feel compelled to do so now.
We have been developing a universal plug and play shaker motor kit for several months. We have done an extensive amount of research and development and have a couple prototype boards we are currently testing. The motor can run off of flashers as well as pop bumpers and will be compatible with just about any machine that have either. Testing has gone very well with all WPC era machines and older Stern SAM systems that were made prior to them including shakers from the factory (POTC for example). We are still trying to get them to work with Williams System 7-11 series as well but we havent gotten the results we are happy with yet. It should also work with Gottlieb, Data East and Capcom generations but have yet to test them. It will also have up to 8 differnet inputs that you can select with an on board dip switch so you can choose to have more than one flasher triggering the motor.
The entire kit is going to be plug and play, no wire splicing or soldering required. The most invasive part will simply be drilling the holes in the bottom of the cabinet to mount the motor. The kit will even use it's own power supply so there will be no need to draw power from the machine's power driver board. We have developed a way to easily tie the separate power supply to the machine's 110vac so that it will turn on/off with the machine so you dont have to unplug it. The power supply will also have addition plugs so you can connect other game mods that take 12vdc like LED strips etc.
Right now we are doing some final testing to make sure we minimize or eliminate any EMI coming from the motor. There is a lot of work involved in a project like this, it is not simply just a circuit board with a few transistors and capacitors. There is even an extensive amount of computer coding involved in a microcontroller. We want to make sure the kit is completely safe to install, after all they will be in all of the machines in our own collection and we know how expensive it is to replace a pinball power board or MPU! There will also be a thumb screw adjustment where you can adjust the motor speed by hand in the 25%-100% range so you can get the perfect amount of desired shake.
Look for more announcements in the next few weeks along with photos/video. We will be finalizing the price point but it is looking like it will be in the $175-$225 range for the entire kit which includes the motor, motor bracket, plastic shield, driver board, power supply, wire harness and mounting hardware. We will also be interested in beta testers, PM me for more information on that if you are interested. The plan is to call it the "Pinshakers Universal Shaker Motor Kit".
