>_< Specifications... i needz them.

So... about six months ago i moved into  new place.  it's great, but the previous tenants kinda trashed the place.  they left loads of rubbish around and were generally horrible to the house.  The previous tenants did leave a few things that are kinda nifty.  First, they left tons of PVC pipe. i have something like 20 ft of 2 inch pvc pipe, 15 ft of 3/4 inch pvc, and 10 or so feet of 1.25 inch pipe.  the second thing they left was an above ground water filter.  The owner's manual to the pump can be found here online: This got me to thinking i could setup a little hydroponic rig in my house. I have a hallway window which i'm too cheap to buy a blind for, and letting a bunch of plants cover it over appeals to me.  However, there's some problems.  The owners guide is critically lacking in any sort of technical specifications and all the info on the web just relates back to the pool pump being used as such.  Sooo... if anybody knows anything about what kind of performance can be expected out of this little dandy, let me know.

Engineering Class Suggestions

I'm part of an Engineering Club at my school and we're looking for future projects that just explore some ideas of Engineering in general. We would like to come up with our own ideas at some point, but for now, a lot of us are inexperienced, so I thought I could come here and find some stuff. So far, we have decided to build a bunch of Stirling Engines and use them for miscellaneous things, but after that, we have no other ideas. Could you guys come up with some ideas (possibly your own or ones that you have done), that are similar to this idea of teaching the basics of making things and stuff like that? Links would be helpful. Guidelines: Because we do this at school, there are certain rules that prevent us from bringing large knives and laser pointers on campus. Power tools and exacto knives are OK, though (IKR?). Also, because we are students, we have to scavenge around for materials, so unless it's less than ~30$, we might not be able to do that either.

Old Engineering Exercise

Hello all! I was just looking through various Maker projects, here and elsewhere, and was reminded of a collage engineering exercise I was told about growing up.  Apparently, they don't do it any more.  My education is only up to an Associates Degree in Drafting and Design, and I never got this at that level. This exercise (near as I can remember) consisted of a student being given a piece of aluminum (I think) and a set of files, a caliper, and a few other small tools.  The student then had to turn the piece of aluminum into as near a perfect cube as they could, using only those tools. Has anyone out there heard of this exercise before?  Maybe done it themselfs? Namely wanted to through this out there, see what people thought.

Is reverse engineering illegal?

Is reverse engineering illegal? Well, if you then go on to sell your version? For example, in an upcoming instructable I'm modding some electronics, well, without revealing my instructable here's an equivilent example: Lets say I buy a little robot at the store, it has motors and the case and everything. Only problem is, it runs on AA's and you want rechargable batteries. Also, the wireless module for some reason is external and is super ugly and annoying. You crack open everything and you find that the needlessly large circuitboards only have about 20 (somewhat) easy to find components that adds up to like 2 dollars. Following traces, you recreate a schematic from the PCB (already did this, that was fuuunnn :P). Now you reengineer the board (still same schematic) so that it's much more compact, you've added a little charging circuit (and correspond boost circuit, replacing a couple of AA's with a lithium ion), and you made it all fit inside the robot (no wireless module just hanging around outside the robot. Now, essentially the schematic is the same, but you've added stuff like the boost circuit and charging circuit. You've also added a few customizing features that make it more special (adding LEDs, microcontroller, cough cough etc.). Would it be illegal to sell a board/kit (incase other people want the board and can't solder smd to good) for people to modify there own robot (same model etc.). Also, the schematic from the reverse engineering is very similar to an example circuit in the main chip's datasheet, and a few other parts are common sense (like some resistors here and there, LEDs, a few extra filtering caps), so the company's circuit is nearly identical to the datasheet, is this illegal to sell?

The cord will be for very light rated appliances or bulbs. Nothing beyond a kilowatt althogether. Specify extension cord wire gauge and anything else needed for the project and it's necessary rating / part number. And most of all, have fun....and don't over think the problem ;-) OK, I blew it.....I knew I had created a similar cord to the one I described, and finally found it....only it doesn't do what I said it does. I merely had Neons that come on when the cord is plugged in.......this is what happens to your memory as you get older LOL.

What I cannot find is someplace that explains step by step the processes occurring that make it actually flash.  The above mentioned circuit is simple enough for me to understand what is going on, but I am not talking about that one circuit in particular. I guess what I am after is a guide that teaches me how to read what a circuit is doing, and for what purpose a component is needed for in a circuit.
