No, it is a motor used to align the laser head inside the Playstation that reads the disk. The motor that spins the disk is very similar to the type found in portable Walkman type casette players. They're large, about the diameter of a quarter and a half inch thick. The laser positioning motor is roughly twice fatter than the original Bit/Zip motors, same length, but has two flat (trunkated) sides. They look very similar to the motor used by that smart fellow that made the Bit powered airplane. These little motors are some of the most efficient I have seen to date. The average motor in these micros (and this is an average example as all the different varieties have different specs. This is how a 1.0 is so much slower than a 2.6 running on the same load for example) has a rating around 1.5VDC @ 80-100mA. The motor out of the Playstation is rated around 1.5VDC @ 10-30mA.
Yes, more efficient motors would make quite a difference in how these micro cars perform. They can be compared to athletes that use their stored energy in the most efficient way possible. Allowing them to run longer and faster with the same fuel supply.
Here's how I discovered these little jewels are so powerful. I once built a solar powered slot car. I powered it with a pager motor because they are much more efficient than the sguare motors that come with the cars. When the solar engine fired, the car would scoot along for about 10 ft or so until the capacitor bank was depleted. I then replaced the motor with one from the playstation. It now scoots for a good 50-100 ft on the same charge at several times the original speed! I don't know exactly as I don't have a straight stretch long enough to let the thing go all at once. This was accomplished at a rating of 3VDC@ 18mA supplied from the capacitor bank. At the V/I rating supplied by the PCB in these little cars, this motor would literally scream down the track. I keep eyeballing that slot car and wondering if I should take that motor out and put it in a zip, but I don't want to destroy it. I might just put a pager motor back in there and have a go anyways.

More pictures available of a cleaner circuit!

This new site should have Data transfer to spare! "I hope"

I'll go for the zipzaps land speed record!!!

Read all about my Zip Dragster at my site!!! Yet another CHEAP project!

Cheap Top Fuel Pro Stock zip Dragster!

enjoy

Hi, i'm kinda new to all this electric stuff so please bear with me. i was wondering if you could show or explain how to do the mod where one batt send power to motor and one to pcb. you help would be much appreciated. please help meee!

Everything is pretty much on the site, please read it, and I'll be glad to answer specific questions, Keep in mind that if you can't follow the instructions maybe this mod is not for you, This mod assumes you have soldering skills and some knowledge in electronics.

Good luck!

This is your ZIPZAP on steroids!!!

....Any questions?

Where could I find some of those little plugs/connectors that you used for the battery? Those are the perfect size for the micro rc cars, and they are easily unplugged, and changed. I have been searching everywhere for those and can't find any. Any info you can provide would be greatly appreciated.

Those come from IC sockets, you can see them on these picture.

you might have to copy and paste the link! but that's where they come from those sockets are fairly common and CHEAP!!! you'll have to cut into the plastic first to get them out without damaging them.

Ok I finally had some time to set the LapTimer in one of the rooms, the most distance I could find was 12 feet, the rest of the house has carpet and ceramic tiles...SO I had to set it up in one of the rooms

Oh well better than nothing. The 4.5v Dragster took 2.11 seconds to do the 12 feet track. Not bad. These took a lot of trials

the steering needs to be pefectly aligned because at those speeds turning is not easy. so the car has to go as strait as possible. I can't imagine having to run 20 feet...Geee!!!

I still believe that ZZs have a poor tire design compared to Bits, the rubber on the ZZs is not even so when you mount the tires and spin them they are offcentered. Bits are much better at this. my Bit runs much more strait.

I used the wifes makeup mirrors to setup the track so as soon as I get more mirrors I will take measurements at 3, 6, 9 and 12 feet with one pass, that way I can compare speed between the 3 feet segments.

Yup, I noticed this too. But only on one of my cars and only the left front wheel. No matter which hubcap or tire I use, it is lopsided. Obviously a manufacturing error.

So is there no way to use an H-bridge to boost amperage to the motor while still using one battery instead of one for the pcb and one for the motor? The h-bridge would retain reverse. Thanks.

dougal · #27 02-20-2003, 03:05 PM

I've got an old pager somewhere. One of these days I'm going to have to find that sucker and tear it down

I don't think you've got the land speed record just yet.

I have a 6 V BATTERY!!!!!! in scale mph, it goes 580!
Top that!

Hmmm! I have all the parts for a simple H-bridge I don't see why you couldn't use the same battery, I don't know if it will actually help but in theory the same battery could feed both the Board and the H-bridge in one side and the direct path to the motor on the other, I'll have to try it.
I'll be using 2 2n2222 and 2 2n2907 for this setup! and hopefully get REVERSE back!

Nive try, but I just took the little 12v battery from my car remote! BEAT that!
