Best (and inexpensive) way to warm an outdoor disability ramp?

I recently had a disability ramp built for the entrance to my home.  It is made of pressure treated lumber and deck boards.  I am putting down rolled roofing to help with slipping.  I would like to make it so that it could keep it warm to prevent snow and ice build up.  I was thinking of doing a solar water heater to feed piping underneath the ramp, but not sure if this is the best way to go.  I also considered purchasing some sort of heat tape to go under the rolled roofing.  What does the community think?

Modulate a transmitter with a signal generator? Answered

Hi I'm doing some experiments with an fm transmitter. Now, instead of transmitting and modulating audio, I wanna try to feed the base of transistor using a ramp generated by a NE555. I ended up with this schematic , would be ok to pass the signal on the base using a 220 ohm resistor and a 10nF capacitor? I suspect that I have to increase the value of the resistor R5. kind regards.

slow voltage current builder: how to increase voltage,current in ramp manner upto the desired value?

Let us assume a system requires 230V ac, 6 amp. When we switch it on, the voltage and current instantly shoots up from zero to 230V,6amp. I want the system to receive the voltage,current slowly ,i.e, when it is  switched on, the voltage,current should increase from zero in a ramp manner ,and when it reaches 230V,6amp, it should remain there till  the system is switched off.

Help with some engineering issues on a folding tail gate ramp?

I'm building a folding ramp to replace my tailgate on my truck. It's going to be used to load/unload a ztr lawn mower. (It's been built primarily from discarded bed frames, with the addition of some expanded steel grating.) Because these mowers are back heavy, and low to the ground, a longer ramp is needed than you need to load a conventional mower. My solution is a spring loaded 8' ramp that is comprised of two 4' sections that fold down and out. It functions, it fits, the mower goes up and down it ok. The problem is that it is so heavy, that after it comes down about 2/3 of the travel, it is very difficult to control. When it comes down hard, it puts tremendous stress on the center - where the two sections of ramp meet. It can be hard enough to break it. I know my welding isn't the best, but that's really not the issue here. This is a design problem. I'm going to post a few pictures, to better illustrate my situation, and to show some of the things I've tried to soften the blow. The picture of the partially folded ramp was taken at the point where it begins to get difficult to lower without losing control. So, to clarify, I need a way to lower and raise the ramp with more control, and or soften the blow towards the middle.  The springs I'm using are 140lb garage door extension springs, the largest springs available at any big box home center. I need to get this finished yesterday, so I'm going to try some things while I'm waiting for a response, like move the springs back further in the bed to put more tension on the whole thing. I'll also post this to the welding web forum, but I started here because I've got a lot of faith in the ingenuity of the instructables community. If we get the bugs out of this thing and anyone wants it in instructable form, I'll do my best. Thanks for reading the War and Peace of ramp questions. -Amir

"Super-magnet ramp" is world's best visual illusion

The video below was awarded Best Illusion of the Year at this year's Vision Sciences Society meeting.  I originally saw this posted in Nature News: In a packed concert hall, Kokichi Sugihara wields a pickaxe and mimes a blow to the stage. "I am a miner, and I have a secret," Sugihara says, adjusting his hard hat and headlamp. "I have discovered a new super-magnet." A screen behind Sugihara begins playing a video. A cardboard structure appears, consisting of four ramps ascending to a raised platform. A hand places a wooden ball at the base of a ramp, and it rolls uphill, before stopping on the 'super-magnetized' platform. As the same trick is repeated for the other three ramps, the crowd lets out an "ooh". Thanks to Kiteman, here's the author's own Web site: Image and video from Koichi Sugihara, Meiji University.

Why will my Arduino not power up when I use an external power supply for my Ramps 1.4?

I am working on my 3D printer and I am using the Arduino Mega 2560 with the Ramps 1.4 board. when I power the ramps board the Arduino will not power up and operate. I have tried moving the header pin across VCC and the other connecter but there is not effect. I have to power the Arduino separately Via USB. is there something I am hooking up wrong or is there damage that I have to fix on the board itself.

What sensor should be used, or what can i make to precisely align a vehicle up to a ramp?

Sorry i couldnt decide how to word my question but here is my situation and i would be gratefull for any input because i am not sure what would be the best or easiest way to go about it.  My car is lowered and therefore i can not park in my driveway without having a ramp(plank of wood) infront of each tire at the sloped base of my driveway. This does not bug me as much as the fact that every time i go to back out of or pull up to my driveway i have to align my tires as best as i can guess up to the ramps, take car out of gear, put on parking brake, get out, check one tire, then the other, and occasionaly move the ramps left or right before i can get back in my car and procede up into the driveway. Ok so its not only my laziness that fuels this project... my mustang isnt the quiestest and when its late I feel bad leaving it idleing (making noise) while i get out to make sure i'm lined up to the ramps. I would love to make some kind of proximity sensor or something that lets me know when each tire is propperly lined up.   I have thought about a few different things like a camera under the front bumper that feeds to a monitor on the dash, (similar to a backup cam) also i was trying to think of a way to use an old cell phone and its camera for this.  IR proximity sensors in the bumper attached to LED lights on the dash that tell me im lined up if the propper LED's are lit. I dont know much about them but maybe some sort of magnetic sensor or metal detector.  One issue is that the placement of the ramps can be detected in different ways depending on the sensors used. whatever the factor is, that is being sensed (reflective surface, metal, tiny magnets) needs to be durable and able to be ran over on a daily basis. Also I want something that can be fairly accurate, although an err either left or right of an inch would be alright. Sorry for being longwinded but i look forward to some ideas! Thanks!
