“You’re like a robot!”
“You’re some kind of robot, you don’t feel anything!”
I’ve heard a lot of this sort of thing from my exes. I assume it was meant as an insult.
So I had this idea to make an actual robot, that bumbles around avoiding obstacles, and, every time it has to stop what it’s doing and change direction, it will yell something like “You’re like a robot!” at whatever got in its way.
The first step of building things like this is to fuck up some consumer electronics. I have a Zig Zag Zog toy, which is a little space alien in a saucer that takes off when a kid bops him on the head, and uses forward and upward-facing IR sensors to avoid the kid bopping him again. ZOG is also an acronym for Zionist Occupied Government, which is one of those terms used by people who think Jews are conspiring with Reptile Overlords to corrupt our American Bodily Fluids &etc. It’s an oddly conspiracy-laden name for a space alien kids toy. Start them young, I guess. Zog has the sensors, a couple of lights, differential drive steering, and a speaker. It also has a second speaker connection, which I can only assume is to warn your kids about chemtrails. It wasn’t hooked up to anything.
Anyway, I took Zog off his ship, and pulled the motor control/sensor board. I’ll be using my own control board. The sensors are easy to deal with, they’re just an IR led and a 38kHz IR receiver. Drive the LED at 38kHz, poll the receivers, and see if the LED is lighting anything up. I also removed the upward-facing sensors, since my robot isn’t concerned about toddler-directed death from above.
The head of the robot is going to be a “Memorex” Ipod/Clock radio. It’s comically over-engineered inside, yet junky. There are 5 different PCBs. The main PCB for the FM radio, amp, and clock timing stuff, one for the buttons, one for the Ipod dock, one for the LCD, and one for the IC to drive the LCD (Fucking blob on board on board. Who even does that?). The main board has an audio amp chip, a separate 4-channel audio processor that does stuff like bass/treble and balance adjustment (none of which is available via the interface of the radio), an FM radio IC (these are practically the size and cost of sand now), a DS1302 battery-backed realtime clock, and a SyncMOS 8052 clone with some Flash memory.
So it’s this insane spread of technologies ranging from the 1980s to now. That processor core is older than I am. You’d think with all that gear, it could be… not shit.
Nope!
The enclosure is ported, like bass reflex speakers. The left and right speakers are in the same enclosure. I’m pretty sure that the ports are not tuned, because The Left And Right Speakers Are In The Same Goddamn Enclosure. This is not how you stereo. Not even a little.
Also, if Memorex had anything to do with this, I’ll eat my hat. The model number on the LCD driver (RT-5228) matches a lot of cheap Ipod clock radios from China.
On the other hand, the two speakers and the Ipod slot make the whole thing look a bit like a face, so I’ll let it slide.
Pictures to come when I give a fuck!
