More Blinkylights

Behold Blinkylights Two!

As of yet I still haven’t got much in the way of input for the arduino so it’s limited to just flashing sequences for the time being. Although I do have some potentiometers I can hook up, adjustable fade time would be nice.One thing that has bitten me though is how much I suck at maths. :P

I may want to consider getting a couple of those 16-Channel PWM chips I linked to previously. Then I’d be able to really get some shine on! :D But next step should be actually assembling some of those power-led driver circuits.

My first Arduino Blinkylights!

My Arduino finally arrived the other day and here’s the first thing i’ve done with it. It’s not much, but I was just sat on the sofa in the living room with a breadboard, a handful of LEDs, resistors and a bit length of Cat-5.

Watch blinkylights!

I also made a pulsing light with PWM. Which is nice and glowy. :) The documentation in the Arduino Playground is really quite nice.Next step, make the High-Power LED driver and hook up some of the Luxeon stars :D

Happy Orbit

Haven’t posted in a while, just thought I’d pop my head out and wish the interweb a happy new orbit! (I like the word orbit, it doesn’t get said enough)

Not been up to much myself. Did nothing over xmas/new orbit, pretty low key.

I’ve got an Arduino and an range of different components on the way from various places. I got me 16x 1W White Luxeon LEDs for a tenner (horray ebay!) which was nice. Unfortunately they’re just sat in their packet at the moment, nothing to drive them with. If I could find that redundant USB lead that’s knocking around, I would’ve already blinded myself with them by now, but not yet.

For now I’ll start out with LEDs and Pulse Width Moduation to dim them. I’m very fond of LEDs, so any kind of LED-based lighting is just happy-go-luckly-magic-land-of-horray for me.

A couple of clickies relevant to my unfiltered ramble:

http://www.cpemma.co.uk/555pwm.html – Simple enough circuit for PWM using a 555 timer.

http://www.instructables.com/id/ECM4Q6NH9IEWOF32MJ/ – High power LED driver circuit for MCUs and the like.

I also came across this chip (Tremendous Geekery: http://focus.ti.com/lit/ds/symlink/tlc5940.pdf) in a couple of Instructables and there appears to be an Arduino library for using it. So I may have to get me one (and spare) of those to play with.

When I’ve got something working I’ll post a vid. Everyone loves videos of blinkylights right?

Anyway, that’ll do for now – laters.

Hampshire Web Developers – Introduction

Hey all! Just a note to say, I’m a Web Developer and I live in Hampshire. I work with Rich and Dave, who told me about the idea. So, hello.Currently I work mainly with PHP5, MySQL with a view to playing with PostgresSQL. I’ve been using a lot of XSLT lately, XML rocks. Also on my to-do list is some jabber fun, not sure when I’m going to get on my arse and do something about it though. I’m very interested code structure, how data moves around different systems and the separate layers within a system. I’m someone who sees their code as their art, and it is art. Or at least it should be. Haven’t really been up to much of note lately, as you can probably see. But I do have a bunch of LEDs and batteries on standby. My solar panel arrived the other day, still waiting on the charge controller. As I write this though the thought dawns on me that I haven’t really chosen the right season for that, never mind. But expect stuff along those lines along with the possible exception. Anyway, I’ll be off, need to perform cat-maintenance…

Damn You Apple!

For their size, the Apple Pro Speakers that came with the iMac G4 are very good speakers. The iMac is now old and replaced, but I can still use the speakers! … no.

Is a 3.5mm jack somehow insufficient in it’s ability to carry two channels of audio? Why on earth do you insist on mucking around with ports?! The only thing I can use those speakers with is the iMac. Well wasn’t that just a stroke of genius? I want to use your speakers! Why won’t you let me!? I would have far preferred the USB Pro Speakers that you could get with the G4 Cube. Those would still be useful.

But it doesn’t end with audio ports. Oh no, you like to fiddle with display ports too. Remember the Apple Display Connector? Or even the Apple MultiMedia Display Connector before that? Thankfully I think you’ve got the point now that one fancy port to carry a bunch of other ports is just a pain in the arse and have stopped doing that one. The Mini-VGA, Mini-DVI then the Micro-DVI ports. I see why you’re doing it, display ports are a bit big. You want to include the port but don’t want to compromise the design of the computer. But is it really necessary on the iMacs?

The real pain though is when, after you’ve finished mucking around with perfectly good ports, do you fail to include an adapter?! That is just cheap and/or greedy, it’s also a slap in the face for the iMac owners, they don’t even need a special port!

My MacBook Pro has a normal DVI port. Thank you. You also supplied me with a DVI to VGA adapter. Thank you again. ‘Course I should bloody well have expected to get one for what you charge for the machine in the first place. It still annoys me though, my mum and sister both have regular MacBooks which have a Mini-DVI port. DVI – Awesome… But. No. Adapter. So when my sister came back from a college trip to Greece and wanted to show her photos on the big screen, she couldn’t, because you just couldn’t help yourselves. If you’re going to do it, then include an adapter. They cost you pennies, and it makes your users life easier.

P.S. While i’m on at you, where the fuck is my remote?! Why don’t I get one!? That is Not. Cool. Good thing mum has no desire to use her remote. *yoink* S’ok though, your man haggled.
