Arduino Robotic Directional Wifi Scanning

I wanted to be able to locate wifi signals, so I built a directional antenna and strapped it onto my panorama robot. The waveguide style antenna built from a used can (explains the name cantenna) looked to be the easiest to build. I bought a pigtail with an N male connector to RP-SMA male connector.  I plugged thisContinue reading “Arduino Robotic Directional Wifi Scanning”

Arduino Shield Etching Thoughts

I’ve kept a list of links I found very helpful lately. While I’m no stranger to a soldering iron and I know how to use perfboard, I have never etched a PCB before and I’ve never designed a PCB. I don’t think I would have had much luck at all without the following sites. IContinue reading “Arduino Shield Etching Thoughts”

Arduino Laser Turret Cat Toy

Laser pointer turret, x y coordinate laser pointer, overgrown cat toy, whatever you want to call it. It has been done before 1001 times over, but I wanted to do it again, for myself. The hardware part of this is extremely simple. I just switched the device from the cat annoyance post from solderless breadboardContinue reading “Arduino Laser Turret Cat Toy”

Panorama Robot

The menu for the panorama robot is slowly getting more useful as I learn how to make the menu structure. Once I figure out saving values between power cycles, I’ll be ready to mount the 16×2 LCD screen. Of course I can’t show the video without also showing the result (scaled to 50% to keepContinue reading “Panorama Robot”

Auto Panorama

I have mentioned panoramas before. This time, it got lazy. I’m sure things will improve, since this is the first run. It uses a lazy susan bearing, 2 Futaba S3004 servos, a Hitec HS-55 micro servo, an Arduino UNO SMD, a pile of brackets, bolts, boards and wires. I whipped up an arduino sketch thatContinue reading “Auto Panorama”

Cat Annoyance

I got an Arduino Uno for Christmas last year, and of course the first thing I think of is laser pointer turret. I played with this for months while I learned the basics of Arduino programming. It was knocked apart when hail totaled my Trailblazer. To simplify rebuilding the turret, I bought a pan/tilt kitContinue reading “Cat Annoyance”
