Two-Wheel Tuesday

Bikes have been on my mind lately. Here's some video inspiration.The insanely good Ryan Leech displays grace and precision in Prague. Julien Dupont uses a motor to explore the city, but impresses nonetheless. Fixies strut their stuff in SF. And for some old-old-old school stuff, here are tricks from over 100 years ago.

What are these two things for? Answered

They are pieces of a video player from a DIY store (you know the little tv thingies playing commercials 24/7) I got when they moved part of the store out. I want to make a dvd player out of it to hang in my dorm but I have a problem (well not a really big one but still). The dvd player has a side way hatch where you can plug an SD card and/or usb drive into. When you do that and the USB or SD contains a movie the player immediatly starts playing the movie when you plug it in. But when you don't put in an SD card or USB drive you get a start menu with: photo camera (just an icon of a photo camera nothing stating camera), music, photo + music, movie, setup, calendar, clock, alarm, auto-power, edit, favorite But I can't select anything in this menu because I don't see any buttons! Also this is not a touch screen (I checked) So my question is, what are these things for, if they are the buttons how do they work and if not where would the buttons be?

Two-way hinges

My wife and I bought an 80s designed house that's not that well designed. We keep one of the litter boxes for our cats in the garage, which is accessed from the inside through the laundry room; and we want to install cat doors so our aging felines can pass through the doors easily to get to it, while keeping the draft from the garage out of the family room. The interior door (between family and laundry rooms) is a standard hollow core and the exterior door (between laundry and garage) is fire code rated solid wood door.  We tried a standard top-hinged door with the cats already, at our old apartment, and the cats didn't take to it, so we we're hoping to do french doors, since they know how to get through normal doors pretty well. But we're kinda stuck on our lack of knowledge about hinge designs; we need hinges that swing both ways. Has anyone out there successfully completed such a design/installation and would be willing to share pics and secrets?

I got TWO books!!!!

Ok, so, it was a pretty lame day at work, what with the apogee server crashing, and me being the only one to sort it. There was three upsides to my day, Firstly, my colleague gave me a cool pair of 3D glasses! (which is good, cos now i can see everything in 3D!) Secondly, my local burger king opened again, and i had an extra large bacon double cheeseburger! Thirdly, my book came, along with, MY OTHER BOOK! I knew that i had got into the book twice, which is great! but i only expected one copy of the book! Alas, i am now the proud owner of two copies of the book! So, i have to ask, does this mean i get two patches? did anyone else get into the book more than once, and received two copies? am i one of a kind? - gmjhowe

My Cycle Two Stroke Engine

Hello everyone, I wonder if any one can help me? I have fitted a two stroke engine kit to a cycle of mine, the thing was running perfect for 220 odd miles then starting stopping and would start again after a few minutes of pedalling. I have changed the petrol mixture and this has seemed to alter things slightly, now it will go but will not rev and only goes to a certain speed then starts kangarooing. When I engage the clutch it will not ideal it just conks out. Could there be something wrong with the accelerator perhaps? Thanks a very frustrated Paul

Cheap Two Stage rocket

If you were to take two model rocket motors and remove the secoundary charge (that pushes out the payload) from one and possibly fill the rest of the cartrage with homemade propellant. if you put one cartrage ontop the other and secured it with a little tape, would that work as a two stage rocket. does anyone think that the flame would travel into the secound cartrage and the pressure would blow out the first cartridge. Just wondering if anyone tried this before and is still alive and happy.

Will the amperage still double with both cells in parallel?
