Drift is in both directions, but usually CW. The program is simplified to the point where only the encoder related code is present. I also directly downloaded a simple encoder program from the arduino website and the problem still remains. I also eliminated serial output and used an LED to...
So I am reading a rotary encoder through an an arduino using interrupt pins for the quadrature output. I'm not an expert, but the system seems to work fine, i.e. gives correct output readings. It is for a pneumatic inverted pendulum, which can jitter, and change the cart velocity very...
Well, your legs essentially are the undercarriage, and that's how hang gliders have worked for years. However, if you assume that the subject can handle a higher impact (probably a better word to use than that) velocity, that would make the design specifications a lot easier. However, the idea...
Just looked at a video of the atlas rope ascender (google it) and thought it was pretty cool. However, I feel as though using a more "capacitive" approach and taking advantage of the fact that ascensions would not occur frequently could allow for the use of a system that slowly recharges over...
What do you think about the feasibility of adding leading edge slats to a hang glider in order to reduce the stall speed and increase the wing loading.
I've seen charts showing nearly a twofold increase in the achievable coefficient of lift because the angle of attack can go so much higher...
yeah, weight/power is way way waaaaay to high for solar panels. Just last week there was an attempt at human powered helis, not sure how it went. However, I do not believe horizontal surface will be a problem, as hph designs are probably going to be the best place for you to start. These...
I'm also interested in building my own as well. The primary concern with every diy CNC machine (IMHO) is going to be a balance between cost and capability. Cost obviously being how much money you're willing to put. This directly translates to your capability, which mainly consists of what...
yeah, pulleys is what initially popped into my head too. the setup is very application specific, so it would really help if you describe your setup/purpose. Try to use as many numbers (i.e. forces, diameters, tolerances, etc) as possible.
Keep in mind that any type of pulley or gear...
Yeah, the wood plug sounds good, as long as your setup is very rigid. I'm assuming you won't have a center drill because you want an entire disc, so you'll have to find a way to mount the plug cutter.
Also don't underestimate making an oversize cut by hand and then sanding it to the...
Thanks for the insightful response. I'm not quite as worried about the brightness as much as I'm worried about the focusing. For brightness, I think I might use a light dependent resistor, possibly with shields so it only accepts light from frontwards.
Can you expound a little more on the...
I'm am looking at the plausibility to make/hack an eyepiece HUD out of a reflective piece of curved glass/plastic, a camera, and a viewfinder/mini-screen.
It would be nice for it to all mount to either a modest sized helmet or a tight head strap. I remember having an old '90s video game...
This is for MEM 220, a undergraduate Fluid Mechanics class, and we aren't expected to put in more than 5 hours each. I have already put in a good portion of that just on this forum. Most groups talk about how pressure increases with depth or do a dumbed down version of Navier Stokes. The fact...
Thickness: I had it in my head that dacron was more of a thick plastic-like material,a good couple millimeters thick. Not sure why,maybe the name, or because there are transparent variants. It look's like it's actually negligible like you said, so we'll probably just ignore it.
Good...
