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

Implementation of two way communication

Hi, I'm working on a project where we're working on a tele-operated robot and we are looking to include the ability to have a conversation. We would be looking to use earbuds and a microphone on the operator side and a speaker and microphone on the robot side. Does anyone know how to go about implementing this? It needs to be hands free on both ends as the operators arms are being mapped to the robots arms. Thank you.

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

lift table from old adjustable bed

Have two old electric linear screw actuators that work great. I Need a lift table but can't figure out how to put it all together. I don't know what width or type of metal use for the lift or the bolt hinges???.  Does it have to be a scissor lift or can I keep the actuators where they are at each end of the bed, wire them to work together and make a lift that way?  I need an affordable way of doing this and it only needs to lift to about 500 lbs. from 17 inches off floor to 30 inches off floor.  All framing is angle iron but seems heavy duty. Anyone's help if greatly appreciated as I just cannot afford to spend $ 1000. + on an electric massage lift table. The pic is after everything but the motor/actuators were removed. Thanks Deb

Why won't my two stroke run?

I have a two stroke weed eater engine (actually from a tiller but it's the exact same) and I am having trouble getting it to run. I have the carb screw tightened all the way so the carb is opened up as much as it can be but when I start it, it coughs like it wants to die then it dies. If I squeeze the throttle a little it will continue running or if I squeeze it all the way it will still run. It just won't run if I let it sit. Also, I am intending to use it to put on a bike and it has a clutch but it doesn't really work that well. It will engage without even squeezing the throttle. Any idea of where I can get a small geared clutch that will fit it? Thanks.

The assembly of the Two Hands Project was complete as we fortuitously intersected directly at the gates to NoiseBridge nouveau. An odd bunch from Chicago/Alaska, Michigan/Boston, and Florida/notsureyet we were meeting for the first time since the inception of the project, and we were ready to rock. Having almost no equipment after meeting up with Mitch and experiencing excellence and consensus in action we go to Sadies house (what a great lady), stay up late, and work all night. Starting the tradition that will continue to this day. Hopping on Paul's tiny folding bike I run across town gathering Mic's, video cameras and miracle fruit. Meeting up with the crew dazed and confused walking around town with tons of gear on their back we were glad to have a brief breakfast with SkyT, Mitch and FBZ before checking out the reMakeLounge.At the reMakeLounge we met up with Inna who saved our lives, 300 times. With her help we were able to talk with the folks at the Internet Archive where we met up with Mang. She drove us over to Oakland, back to SF, and finally back to the Airport. If there's one lady that made the SF leg of this trip possible it was Inna.Mang and his roommate Mike have an awesome Hacker Space appended to their home. We were given a rare peek into Radish Research which they opened up to us. It's been amazing how much people have opened up to us this trip!

2 Different dreams in the same place?

I just realized that I had a dream this morning in the same location... twice. By that, I mean (in a gaming sort of fashion) you started playing a game, then halfway through, your mom called you and you had to save your progress. You then resume to your most recent progress in the game and continue playing. It felt something like that, and I can't explain how that happened (also given that I had the first one weeks ago). Out of curiosity, has anyone else experienced such a thing? And if so, what are they called (if at all)? ***It's been a while since I've done anything in Instructables lately.

230vac extract fan speed control - help

Hi I'm just in the process of refurbishing the bathroom of a flat I bought. It's all been plastered out already and I realised I've no extract! So, I created a plenum at hi level and mounted a fan under floor and have ducted it out. I want to run the small AC extract fan 24/7 at low speed (kinda tick over speed) and then switch it to hi speed when either the humidity goes up (cos the shower is running) or the light goes on (assumes someone's using the WC!). I can't get to the lighting wiring so I'll need to sense that remotely. I can fit a humidity sensor in the duct work. I've tried everywhere to find something suitable with zero joy. Is anyone here able to point me in the right direction?

Two way intercom design for tele-operated robot

Hi,I'm working on building a tele-operated robot that will be able to send signals generated by moving your arms and mapping these to the robot arms. I'm looking to add an intercom system to the robot that would allow for the operator to speak into a microphone and come out a speaker on the robot and a microphone on the robot so send audio that someone speaking to the robot generates to the operator.I've currently been looking into VOX circuits and walkie talkies but all walkie talkies I have seen require both sides to use a headset. It would be fine for the operator of the robot to use a headset but it would be better for the speaker and microphone on the robot to be out loud. Does anyone have ideas about how this type of system could be implemented? Could I replace the PTT button on a walkie talkie with a voice activated switch kit available online?Thank you.

2 to the 2 to the 22 power

I recently took the pamel (pennsylvania math league test thing) and for one of the questions it said: rearrange the numbers 2 in anyway with mathmatical symbols to get the highest number possible. I though the answer was 2 to the 222 power The answer was 2 to the 2 to the 22 power Is this correct? I thought that you would multiply the powers to get 2 to the 44 power, now have the power to the power and get 2 to the 4194304 power.

Could this cooler cool?

My idea is that instead of putting ice in the same spot as the beverages, you put them away from them. In the cooler, instead of four walls and one bottom, there would be eight walls and two bottoms. In the inner walls(the walls in the cooler) will carry ice water(with salt to make it colder perhaps?) and so would the very bottom. The center will of course carry the beverages which would become cold by the ice from the bottom and the sides. For a lid, I was thinking of just plain of latches, or a ledge on all four sides to support a lid. Also, which is better for a cooler? Foam or plastic?
