deadman's DNS
rsbohn
14:07h
Have a situation where the standard DNS system isn't keeping up with my various linux boxes. Os I came up with this idea. Each computer claims a hostname and IP address from a web service. Then you can contact the computers (ssh etc) using a simple lookup. To claim an address you simply fetch http://deadman/hosts/~myname~/claim. To lookup an IP fetch http://deadman/hosts/~yourname~/?ip. The response is (text) along the lines of (10.0.0.1 10.0.0.2 10.0.0.3), or a list of addresses, space delimited, in parentheses. A simple perl or python script on the client then parses the reply and prints the (best?) address. So you can do ssh joe@`deadman-lookup gnarly`and it works. There could also be a web proxy service: http://deadman/hosts/~yourname~/port=8080/index.html Now watch me code this in ruby (with WEBrick). ... Link
USB Interface on Butterfly
rsbohn
09:51h
OK an ATMEL AVR Butterfly, not the flying insect. I have a USB to Serial adapter I bought from Sparkfun. I want to hook that up to the Butterfly. I have to figure out if the Butterfly RS232 port is -12V to 12V or just 0V to 5V. If it is 0-5 I can just wire it directly, otherwise I will have to bypass the level converter or use a different port. Am I insane? ... Link
Plumber for Windows?
rsbohn
09:40h
Well it would be nice to select some text (have to be copy?) and then the plumber checks the clipboard and acts accordingly. How about better default handling: Don't know how to process this, what should I do. Then you could add rules on the fly. cf Plumber Wiki Page on the plan 9 wiki. ... Link |

Arduino Starter Kit
MAKE Blog How-to Tuesday posted a challenge: Optimize the sketch code for a pressure sensor bar graph. Here is my second attempt: int gate[] = {10, 20, 50, 100, 200, 32767}; void setup() {DDRB = 0b00111110;} void loop() { int dval = 0; int rval = analogRead(2); for (int x = 0; rval... 12/3/08, 5:42 AM Measuring Supply Voltage
I'm running my latest handheld computer on solar power. It starts up when the sun rises and runs all day. I started wondering how I could measure the voltage coming in from the solar panel. I came up with a way to use a diode and a resistor and the... 7/29/08, 9:53 AM Ten Pin ISP adapter
I've already built a six pin ISP adapter, but my Olmex cards use the ten pin ISP. I put a header on a scrap of perf board, added an LED for the heartbeat, and then connected the ten pin cable. Actually it is a fifteen pin cable, off a joystick... 7/16/08, 10:00 PM Hello 5x7 Style
Wrote a new firmware for the 5x7 display. Now it scrolls out 'hello' over and over again. I'm running it on a solar panel, so it wakes up with the sun and runs all day long. When I built the LED matrix I put resistors on the five columns. I'm starting... 6/17/08, 12:48 PM Provo, Utah
With a walkable downtown and access to two Universities, Provo Utah is a great location. I live next door in Orem. Kipplinger: Provo: Pristine Tech Mecca (Video) (Text) 6/2/08, 10:07 AM Another release of AVRISP sketch
There is a new release of the AVRISP emulation sketch for Arduino: avrisp.02.zip. This one should work with Mega8 and Mega168. mega-isp 5/28/08, 4:48 PM Sorting Out Page Sizes
There is a new release of AVRISP Emulation for Arduino. This is an Arduino firmware that allows you to program other AVR microcontrollers. The new zip file (avrisp.01.zip) should compile on the current Arduino IDE, and I changed the comments that put the wrong labels on the SPI pins. Go ahead... 5/27/08, 11:31 AM Flash Problems
I'm building a project using the AVR ATMega8 microcontroller. Once I got the thing wired up to where I could write firmware to it I found that it was always failing. I made a .hex file full of 0x10 values (256 bytes worth) and tried uploading that to the chip.... 5/16/08, 2:56 PM William's Arduino Board
I'm building an Arduino-compatible board for William. I'm building it on the Evil Mad Scientist MegaXX8 business card. It will have four built-in LEDs and a USB interface. It will also have connectors so he can use it with a breadboard. Perhaps we can connect it to some of his... 5/15/08, 7:26 AM Cybord Signal Detector
Some digital radio signals use Frequency Shift Keying (FSK). This often has one frequency for a Mark and one for a Space. I plan to build a cybord or other chip that will decode an FSK signal, producing three different values: NO_SIGNAL, MARK, and SPACE. The signals would then go... 5/15/08, 7:20 AM destinations
