Looking for ideas?

I am looking for ideas here from all you "experts" (where an expert is described as - Ex (a has been) spurt 9 a drip under pressure)) Nothing like insulting the unpaid help! before they start :-)  happy New year everyone. OK A friend has a model of a fair ground ride, this is a steam yacht, http://www.youtube.com/watch?v=zp76RTbqqLk he wants to animate this and would like the motion to be realistic at the scale size. He had tried a number of mechanical solutions, cranks etc but they all give a jerky motion and the real thing is very smooth. Any suggestions. I am inclined to think this is a micro processor solution with either a suitable servo motor or similar driven to mimic the inertia of the real thing. ideas folks?

Can the CP2101 USB to serial IC be used to connect a microP directly to a PC without an RS232 port and a MAX232 IC?

Sparkfun makes an excellent breakout board for Silicon Laboratories' CP2101 IC. It looks like this board could be used to connect a PC to your microprocessor through a USB port without having to use a MAX232 IC to convert the TTL voltage levels to the serial port voltage levels and then a USB to serial converter. Drivers are available so the PC sees the CP2101 as a COM port so hyper-terminal could be used to communicate with the microP. The 'S' in USB stands for serial, it should would be nice to connect a PC to a microP using only one piece of hardware. Am I right about the CP2101 providing this ability?

Need old Microprocessor CPU chips

I need a bunch of old CPU microprocessor chips for a craft project.  They can be totally non-functional.  I'm interested in the physical package, not working electronics.  I'll pay postage and agree upon a sales price. However, I'm most interested in older chips, the 486's and early Pentiums (586's).  See figure 2 as a guideline.  I need a bunch ( > 30) but I'll buy them one at a time if necessary. All are for an Instructable, so it's for a good cause.  Any advice for websites that are selling to old chips would also be appreciated. Thanks for any help!

can anyone help build a basic computer?

The fact is pictures use 24 bits. It is not simple to use available microprocessors to make a computer at home. Way too many pins Well I think that a z80 microprocessor and two 8 bit presettable counters could deliver a picture with 24 bits. Did anyone really ask for microsoft? What task would you work on? Example number one 1)  computer division : this is binary number division with check in the loop  that you just drew up. The microprocessor only has about 125 commands that you write down.  A command can be as simple as jump to line 0000 0000 0000 0000 . this can be a simple loop that has to be done or the chip is scrapped.  The number 2)  Is there a picture chip like the commodore 64 has?  Find one. An easy chip.   3) Are there any monitors left?  Did any one ask for those  sounds microsoft has ? Most people should have figured out apple computers earlier.
