Telerobotic Tank

telerobotic tank

the ‘mars rover‘ is a telepresence robot made by robo-hobbiest kerwin lumpkins.  he created it as a mock up of the real mars rover, but on a more down-to-earth scale.

controlling the tank is a general purpose robotics development board, also designed by kerwin.  the darc board takes input from infrared and sonar sensors, controls locomotion and camera aim, and has basic ability to make decisions based on a combination of its immediate environment and operator commands which are sent to the robot over a rf modem connection.

here’s what makes this cool.  if the robot detects that a given command would place in in jeopardy (such as running into a kitchen cabinet) it will abort and send back a warning to the control station.

to better simulate a real mars rover system, kerwin uses some tivo-like time shift software to delay the incoming video signal 5 seconds.  this makes controling the rover more difficult and is why onboard decision making is a must for your own martian explorer project.

Foxblocker Filters Out Fox News

Fox Blocker

oh yes folks, just what you’ve always wanted. the foxblocker is a little piece of metal that screws into your coaxial cable on the back of your television (or cable box) and will block out the news channel, FOX News. this is a very interesting concept because in theory, you could start to daisy chain these together and filter out whichever stations you wanted. i think it’d be fun to see these made into “nickelodeon blockers” or something to that effect. whatever will make your little brother cry.

it’s available now for $8.95 from the official website. thanks to off the hook for informing me.

wow, such heated debate!  the fox blocker is what’s called a band-stop filter.  you can make your own and block whichever cable frequency you wish.

sidenote: in the old days, cable companies would screw a few of these on your line to block premium channels that you hadn’t paid for.  good samaritans would occasionally crack open the cable box and remove all the filters for everyone on their block.

i thought the band-stop filter post was a nice juxtaposition to yesterday’s amp, but that’s just me.  if you are more interested in making things louder, the chu moy amp circuit used in two of our previous posts might be a good place to start for your dreamcast amp guts:
