This is my 2nd successful robot in a row! Im so proud of myself...
Anyways, this is my robot, Fettuccine, 1.2 (fettuccine is the series of 555 timer robots, and 1.2 because it is my first one, the .2 because of a resistor change in the schemmy). It runs on 2 555 timers, 2 transistors, and all the components needed for astable operation.
It is a completely custom circuit! It is powered by a 3 volt battery pack that i made in 2 min by taping peice of wire from + to - and then a wire leading from teh opposite ends. I then wrapped it in electricians tape (bought 10 500ft reels for 2$!) and soldered into robot. The dual 555 are run in an isolated astable mode, with the resistor from pin 7 to pin 6 being a photoresistor. The output (pin 3) is connected to a 2907A PNP transistor, which its collector connected to the motors and green LED. I used a 10k resistor for the connections between pin 8 and pin 7, and a 10uf cap. between pin 1 and pin 2. This is exactly the same for the other 555, which are independent and run their own motor.
Everything is then encased in a chicken nugget container that i found in my moms tupperware (I had to fight her for it lol). The motors are bolted on using rector set peices, which are easy to use. It slows down when encountering bright light, and speeds up when encountering no light. I accidently put on 100k ohm resistors in place of the 10k, and it took the robot 1 minute to cover 6 in! Explanation of photos folo below.
1310: Note the "high quality" and patience into puting the circuit into its incasement. You can see the 'antennae' aka the photoresistors quite well (red things sticking out in bottom porton of photo)
1312: I think that was a close up image of the photoresistors, which diddnt turn out too well.
1313: better pic of photoresistor. You can also clearly see the coaster and my dog in the background, with the circuit board bolt in the foreground (coaster touches ground, look closelier).
1314: clearish image of the 2 555 and the transistors. Also the caps are easily identified.
1315: bad image of 555 yet again
