Speak-n-Ode

nobody@flickr.com (barnoid) — Mon, 18 Mar 2013 14:39:03 -0700

This is the latest incarnation of Ode, a bad poetry generator that I first made when I was 13.

See the web version for more information and the code.

This version runs the output of the Ruby code through espeak on a Raspberry Pi.

The music that plays behind the poem is called "Life" and is taken from a four part sequence, "Birth, Life, Dying and Death", composed by Matthew Barton and myself at about the same time as I wrote the original Ode.

Raspberry Pi - Project #1: GPIO to Breadboard Breakout

Using the breakout adapter and an old floppy drive cable. The cable is too big by eight holes but the excess can just hang off the end.

This video shows to some extent how the bottles are played.

This project by BuildBrighton member Jason Hotchkiss was on display at the Noise Toys workshop.

LED display and clock

My latest project. I'll write this up properly at some point. The plan is that it usually displays the time and scrolls messages when instructed to over the serial port, and possibly more.

BuildBrighton White Night Workshop - Setup and Session 1

nobody@flickr.com (barnoid) — Sun, 31 Oct 2010 09:28:49 -0700

barnoid posted a video:

This is a timelapse video of the Light Brigade workshop run by the BuildBrighton hackerspace as part of the White Night festivities.

The workshop involved soldering together a badge consisting of an RGB LED, a microcontroller, battery, IR LED and IR receiver. The badges have a unique ID which is represented as a colour on the LED. They constantly transmit their ID using IR, other badges can receive the transmissions and collect colours which they cycle through on the RGB LED. They also have a zombie game mode where a badge can become "infected" and flashes red. It will then infect all other badges that receive its transmissions.

It was far more popular than we anticipated, some people waiting over an hour for a place and many being turned away. A lot of work went into it, particularly from Mike and Matt and I think it was very successful, people seemed to enjoy it. I saw several people who'd never soldered before pick it up and walk away proud of the flashy badge they'd just made.

This video covers 19:05 until 21:20 and includes some of the setup (you can watch Toby and Mike working on the code and us eating our dinner) and the first session. It was made from 1776 shots taken with a Canon Powershot S2 running CHDK, then made into a video with ffmpeg.

Cress in Progress

For the next five days this is happening in the cupboard. Cress really moves fast, the seeds started swelling as soon as I put them on the cotton wool.

Humidity and Temperature Sensor

This is my Honeywell HIH-6130 breakout board populated with components. I tested it and it works perfectly. I only made one, this is a composite photo to show the front and back.

My First PCB

nobody@flickr.com (barnoid) — Sat, 18 Feb 2012 11:13:34 -0800

barnoid posted a photo:

Actually my second, I didn't realise until I was about to start soldering that the first was mirrored and so couldn't work with the surface mount chip.

It's a breakout board for a Honeywell HIH-6130 humidity and temperature sensor. I designed the layout in Eagle, printed it out and transfered some toner onto the copper board by pressing the print against it and heating with an iron. This didn't transfer enough toner though so I went over it with a pen.

BuildBrighton's Noise Toys workshop was followed by an evening of accomplished performers of loopy-beepy noises. This is our own Unsymbol with projected visuals by our also own Luke.
