MY NAME IS ANTHONY THE 11-YEAR-OLD BOY WITH THE BIGGEST BRAIN SINCE THE GUINES WHO INVENTED THE DVD PLAYER. I ALWAYS DREAMED OF BUILDING A BIKE WITH TIRES THAT NEVER POP,A BIKE THAT I CAN RIDE ON ALL TERRAINS(LAND,GRASS,WATER,AND AIR)THAT HAS SLAM BRAKES.
Add your comment I want to do that, but I can’t. I want a security wave between transmission media and the receiver.
I’ve made the ultimate technology, the Cool-O- Matic. It has a very fast spinning motor at the left side and a multi led light on a small circuit board attached to a small button on the right. A medium sized normal red/black switch on the right and the white cardboard is metal encased, which I just newly designed so it’s shock proof. I added a resistor and a black thingy that was deepened in on the middle that was on a circuitboard connected to a large sized radio. I used a 9V snap connector at the bottom and get a small plastic fan out of the normal little fans that take the double AA or the triple AAA. Take that fan or any other fan you can find and use that on the top of the motor then put the name of the thing, please don’t take my name its awesome. On the the top of the the front of the cardboard then encase that with see through plastic you can do the same thing with the led light. Just make sure the led light isn’t poking out of the card board you can add some metal or something on the back of it so it reflects forward then you can make the battary pack that has one end glued onto the card on the left and put a screw in on the right. Then you can add anything else you want on it theres a little extra room.
I plan to build a time machine from my broked down geo metro, and parts from radioshack. I will use a 555 circit to control the time shift, and also my mystical quartz crystal ball I just got off ebay for $75 since you need a crystal for time travel. I’ll have to fix the engine first to because you have to be going 80 mph before you can travel in time as well. I’ll let you know how it goes.
what can i buy off the shelf from R.S.
to build an electronic timer
i want to activate a timer with a simple push swith, intially this timer runs to twelve minutes and when it counts down to the two minute mark I need an audio beeper to come on for ten seconds,then at the last two seconds prior to shutting down, I need a six volt output to run a relay. also in the timing sequence when it comes to the two minute mark and the audio beeper comes on and if you activate the switch, you get the timer this time to go to six minutes, and when the timer gets down to the two minute mark again it gives an audio beeper for ten seconds. are there components to build this
at radio shack? thanks Chris
since i opened my old phone i have a tiny microphone and a tiny speaker
my idea is to make a receiver and a transmitter with these two so that i have a tiny hide-able intercom 
it would be really cool kinda hard though
another idea with the same components is to create
just a simple transmitter (with the microphone) which will be emmitting in frequencies which i will be able to listen to through a simple radio
