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?

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?

Q1 needs to flash six times .25s on .25s off and then stay on for 10 seconds Q2 needs to turn on and stay on for 15 seconds Q3 has two functions either: red LED on for 15 seconds OR red LED on for 1 second then green LED on for 15 seconds Q4 needs to turn on and stay on for 15 seconds I only want one LED option to be on at anyone time across the three slave boards.

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!

I'm fairly new to the world of DIY electronics, but I would like to start working on projects that incorporate microprocessors. I've been looking at many of the projects that use arduinos, but I was looking for a little more info on them. I'm sorry if these are stupid questions but with my little knowledge about this stuff I don't really know any better. Could a single microprocessor be used in place of an arduino? Could an arduino be used to program an IC chip and then the chip be removed and only use that for the project or does the whole arduino have to be used? and any other tips you have for me to help me learn more about stuff like this is greatly appreciated. thanks.

Asked by sylviebarak 4 years ago
The servo would be used to move eyes, eyelids and possibly the mouth. Basically I want to operate a servo without using a radio control unit Space and weight are limited. I am a pro puppetmaker and know this kind of device would be very useful. The motors would be operated by a switch in the puppets mouth. In the case of a costume character I want to put a push switch in the perfromers hand and have them operate the mouth.
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.
