hey that's pretty cute! Is the bootloader burner on the kit chip?

Can you post your bresenham implementation? I've been getting odd/inaccurate results and haven't been able to figure out why.

Well, as someone mentioned above you would probably do better with Lego Mindstorms than Arduino.

That said, what is the "end product" you are referring to? If it is a self-generated/self-designed project, there is no end product until you complete it. If you don't like programming but have ideas, maybe you can partner with someone or hire someone to do the programming parts.

I sort of know what you mean - but if you are doing something custom, there is no help for getting your hands dirty (or hiring someone to get their hands dirty).

Maybe you would enjoy using Scratch for programming?

Doesn't work with Arduino (afaik)

Hi - not ink jet, but I've had much success using commercial PCB transfer sheets at the local copy shop. Just put in the transfer sheet and copy the layout on to it, then iron on to the copper. Most copy machines are laser-based these days.

The transfer sheets are cheap and reliable. I started using these for my custom boards after wasting time with an old laser printer along with the laser print-on-paper transfer method. Would rather waste the time on writing bugs in my code...  smiley

Hi - someone asked me about this the other day so here is the info I gave him:

This is the  sensor I used:
http://www.acroname.com/robotics/parts/R48-IR12.html

comparison of the Sharp sensors:
http://www.acroname.com/robotics/info/articles/sharp/sharp.html#e8

I got a better price at http://www.pololu.com/ as I recall - but wherever you buy it **Be Sure* to get the connector with it - it's a non-standard connector that is hard to find.

Here's some code for reading the sensor:

Using a capacitor with the Sharp sensor (this was important):

I don't know the innards but the Wiring (uses the ATMega128) board IDE might be worth trying: http://www.wiring.org.co/

Is anyone connecting at 115200? I'm able to connect at 9600 (Macbook Pro 10.5) but no faster rate.

You don't have enough analog pins on arduino to run that many sensors directly but you can use a multiplexor. There is a good tutorial on the 4051 chip in the playground. It's pretty easy.

I think it depends on the sensor - some are very narrow beam, some are more funnel shape. Arconame has a good comparison chart. Also, I found this article very helpful @ info regarding capacitors and the mythical need-to-ground-the-case issue (no)

I'm using the Sharp GP2D12 sensor - 24 of them, multiplexed through a 4051 chip (though I have only hooked up 8 so far). If you decide to go with the Sharp sensors, a capacitor across the sensor power/gnd is critical. It doesn't mention that in the data sheet but I've been digging around and found some helpful info from other users. Also, 10 sensors are going to draw more current than the arduino can provide so you will need to power them separately (with a common ground).


I found the prices here to be the best:

Also - buy the cable. The connectors are hard to find elsewhere.

Wish they had a screw terminal block option- I don't trust the push-in connectors - though a 2x screw terminal is would be a strange beast.
283  Forum 2005-2010 (read only) / Bar Sport / Weather proofing a Sharp GP2D12/Arduino? on: October 02, 2009, 07:16:12 pm
Anyone have experience weather proofing an IR sensor like the Sharp GP2D12? And for that matter - a 12v power supply + Ardunio board.

I have the opportunity to install an interactive light piece in a park for 4 months- likely this Winter. I'd need to revise a bunch of things for it to be outside but before I even consider it, I'm wondering about moisture, extreme temperatures, placing the sensor within a plastic or glass housing, etc.

Thanks - I'd be interested in any ideas, issues or links.

I've ordered from FutureLec just once - don't recall a big delay. I did have trouble with one of the boards I bought and their customer support offered to replace it, etc.. I would order from them again- but agree - they are a bit hard to get a hold of sometimes.

Hi - just came across this Processing tool: InitSketch

http://inittemplatep5.sourceforge.net/InitSketch_P5_Tool/Home.html

It does a simple thing: loads the contents of a default text file into your sketch. If you get tired of always typing setup() etc. or want to use a custom header or comment block, this will do it.

Just tried it in Arduino 21 and it works. (OSX). Perhaps this could be included in the Arduino dist?
