Making Ice Cream

A couple years ago, my girlfriend wanted to make some ice cream. I didn’t have anything going on, so of course I was up for this. We went to Wal-Mart and got a Rival FRRVCB40-BL. It seems to work pretty well, especially for only being $25. I mostly go by the recipe in the manual,Continue reading “Making Ice Cream”

Beyond Logic Serial Analyser Log Printing

This was a quick hack with some perl to chop up the logs and spit out the results I wanted. This is not normally something I would share, but I want to be able to find it again, should I have a need for it. The first one replaces the non-printable characters and separates theContinue reading “Beyond Logic Serial Analyser Log Printing”

Rimage DTP-4500 RAS 13 Initialization Sequence

Initialization sequence for Rimage RTP-4500 RAS 13 autoloader duplicator robot. Serial sniffing with Beyond Logic RS-232 Protocol Analyser in ASCII mode. For interception, I made a cable with 2 8-pin mini din connectors wired straight through after patching through a solderless breadboard. Connection to PC is 38400-8-N-1 using hardware flow control. I will post pinoutContinue reading “Rimage DTP-4500 RAS 13 Initialization Sequence”

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”

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”
