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”

Toner Transfer on the Cheap
I recently made my first PCB with toner transfer using an iron. It was pretty ugly. I bought a cheap-o laminator from walmart for $25 + tax. It’s a Scotch TL901. I used masking tape to hold things in place. It worked well enough that I’m not going to complain. I never realized what aContinue reading “Toner Transfer on the Cheap”
From n00b to Etching an Arduino Shield
First things first, a picture demonstrating success. And a video! Next, a link to the resources I needed http://www.ragingcomputer.com/2012/04/arduino-shield-etching-thoughts After that, pictures. Lots of pictures.
Arduino IRremote + Servo Problem
I’m having some sort of issue with this. The servo is twitchy. Using https://github.com/shirriff/Arduino-IRremote and http://arduino.cc/en/Reference/Servo It twitches just by having both enabled. I’ve included the code I used for the first part of the video. If you know why this is happening, I’d love to hear it.
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”
Crappy Wireless Device – Auto Reset
I’ve got a piece of crap wireless network device. It disconnects or the server part just locks up, or dies, or I have no idea, but it stops working. I am not fond of this behavior. It seems to work pretty well after it’s reset. It could be any misbehaving device like a modem, router,Continue reading “Crappy Wireless Device – Auto Reset”
Hexbug Spider LIRC Control
As soon as I knew they existed, I got a Hexbug Spider. I wish these things existed when I was little. It is COOL! Now that I’m older and can buy toys for myself, I can do more interesting things with my toys. The Hexbug is IR controlled, like a tv remote control. I haveContinue reading “Hexbug Spider LIRC Control”
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”
