a GLaDOS lamp project

ok so after the failure/abandonment of the first build of the papercraft d0g model project from half-life 2 i started last year, i've gotten my filthy hands onto bigger and better things: a 3d printing project of the GLaDOS robot from Portal 2

so it's a lamp, and it's safe to assume that almost everybody loves lamp. it's not the open source lamp stack thing, but if you don't know what that is then that's probably a good thing

i don't know how much it would sell for on sold or maybe just in the thread slaw here, but i'm hoping to raise at least $500 or so for a childrens charity like child's play or starlight foundation but someone else can work out who or how to spend whatever it might sell for
-----------

bit of an idea of cost's of the consumables and hardware. $160 for 4Kg or plastic and $40 for the nuts & bolts fittings. $160 for the wiring and led's and diodes. haven't sourced the electronics controller board for the servos (maybe i'll try and use some kind of small transmitter) or led heatsinks (not sure the way i'm wiring it up that i'll need them) also haven't found the right servo's for the moveable actuating parts yet. or the ic controller board for the servo's.

here it is partially assembled to see how it looks before i take it apart again to start sanding, priming/putty filling, painting it and eventually running a wiring loom through it to get it lit

here's what it will look something like when finished, with the led's on my build a bit dimmer than the 3W floodlights on this one. and the orange eye led will work when i can find one, i hope

I could read your post Trillion without translation. What's going on? Also cool project.

Nice work Trillion. I'm a bit surprised at how much its costing though. Post a video when you get stuff moving.

more like next step skynet.

off topic to OP question: Is there a cheap and easy way to DIY webcam motion capture for 3d animation using open source software so I don't have to pay megabux for a hobby?

On topic for OP: Use an arduino. I've just got my mitts on one and it can do all sorts of cool s*** like turning led's on and off, driving motors (steppers, dc brushed, servos to set positions) and make sounds / detect sounds / light (so someone turns on the main light the glados lamp could swing down and set its gaze upon the doorway).

I got this one: http://www.jaycar.com.au/productView.asp?ID=XC4262 It's a 'freetronics eleven' but lists it as 100% arduino uno compatible. Comes with a bunch of s*** that would be perfect for this. Word of warning though, the micro servo they supply is easily over-driven. I managed to f*** it up in the first minute by not setting the limits properly :( Better to learn on that one though, than on a $100 high torque servo.

thanks for the tip. i was thinking of using a zigbee board but it's more suited for another project i have on the backburner (the foam trainer r/c aeroplane)

i remember watching as the arduino was still coming up through kickstarter or some similar crowd funding thing. look's like they've come a long way since it was little more than a breadboard pcb with basic experiment ideas to do

i saw a tonal ic that looked like is would be neat to include inline somehow. it's tuned to pickup whistle frequencies but i'll have to dig in the /. archive to find the link

also for orange, you can buy orange LED's. Or were you after high brightness ones? You mention heat sinks on the LED's so I assume it's those stupidly high current, blindingly bright ones?

Without knowing how big the thing is, you can get normal sized servos that are capable of some high torque. Make sure you get metal geared ones. You can get yum cha ones like the one I had in my RC car, not quite as good as a name brand one but it did me just fine. I just had to make a brass bush after a while because the plastic one wore out. You ever tried drilling a 2mm hole in a 3mm round piece of brass? Not nearly as hard as I thought it would be.

meh i still need to source 2 x 608 bearings so the weight of the hanging robotics assembly glides smoothly without the wearing effect that a copper/brass bushing would exhibit.

yeah the orange LED i need to find in the star configuration @ 1W (not the 3W blinding ones) heat sinks just because I haven't tested the 1W ones for heat capacitance yet so i don't know if i need them (might be overkill buying them and then not using them or using them in a second version of the build if this ones works out)

some other thingies that will be neat tweaks would be

https://dlnmh9ip6v2uc.cloudfront.net/images/products/1/1/7/0/5/11705-01_medium.jpg an inline switch for convenience inside the 12vdc circuit

http://www.limpkin.fr/public/thewhistled/PCB_only.JPG a whistled(?) to whistle a tune and have it turn on or off or for programmable movement positions (that's getting a bit more technical but would make good use of the Microsoft Robotics Developer Studio)
maybe having the sensor recognise the ap-er-ture-sci-ence tune: which i think would be something like A,G,C,G,A

and one of these would take all the brain drain tinkering out of the LED fixing.

i'll have to shelve it and get back to real work before i can budget for ordering and having all this shipped from overseas for all these cool extra bits though




here ya, banana for scale :)

^^are you sorry for potato? :)

jaycar sells a bunch of star led's and their drivers, you could go to a dumpshop or recycle yard and pick up an old lamp for like $2 or something and just use the inline switch off that. An old 240v inline switch will easily do your small DC voltages.

I know the arduino is capable of detecting and acting upon sounds of certain levels because that's one of the projects in my kit but I don't know about specific tunes. You can get a mic "shield" for it (shields are just boards that plug in) and I'm sure somewhere on the net someone has some code.

For bearings, dunno where you live but supercheap, autobarn, beenleigh bearings, bunch of bearing shops in slacks creek or if they're small ones then mr toys sells RC car bearings or ozrc up in geebung will have a bunch of them too: http://stores.ebay.com.au/OZ-RC-MODELS
