As for a motor-controller, you must have one to drive the motors. The R/C receiver is simply there to tell the motor-controller how fast to go... it works with very small current (5 milliamps ro so) and your motors will need somewhere around 25 amps (25,000 milliamps). The arduino in this project was only used as a translator between the R/C receiver and the home-made motor driver that I built. You can get around using the Arduino board by using a Sabertooth 2x25 motor-controller that essentially has an Arduino chip built in to convert the R/C signals from your reciever into motor speed signals that directly drive the motors: http://www.dimensionengineering.com/products/sabertooth2x25 If you need more information, I have a website and a forum for more detailed questions: http://prototyperobotics.com/forums/forums/lawnbot400 cheers, JD tag:makezine.com,2005:msg.4613 2013-06-09T17:59Z 2013-06-09T17:58Z johndavid400 I know this is old but I hope someone will see it. I have two motors from two razor scooters, 24v for sure but not sure on any other specs. Would I need a speed controller or can the rc reciever control them direct? Is that some of the function of the arduino? Thanks. tag:makezine.com,2005:msg.4612 2013-06-08T20:37Z 2013-06-08T20:36Z DrPepper23 Has anyone got this to work with a piezo?

They want $15 to ship it -- and the globe only costs $10! Seems a bit excessive... Thanks. Fun project, by the way! I'm done with the construction, about to wire it up. -Dan tag:makezine.com,2005:msg.4610 2013-05-28T18:42Z 2013-05-28T18:41Z dchernikoff Anyone find a cheaper source for the globe than 1000bulbs?

When I've seen the features of the immersion heaters Norpro 559, I told me that could be a problem becouse I'm in Italy and here we have 230V at 50Hz. What I can do? Which parts I have to substitute? Thank you very much tag:makezine.com,2005:msg.4606 2013-04-17T20:19Z 2013-04-17T20:19Z albi I couldn't figure that out, either. Evidently it only connects to Windows machines (e.g.: I succeeded in getting photos into a Lenovo Thinkpad). I can't remember if I needed to install the drivers or not from the CD-ROM. The written documentation is fairly bad, too. tag:makezine.com,2005:msg.4605 2013-03-16T14:46Z 2013-03-16T14:46Z GFavalora Hey friede00, it looks like you forgot to add the photo link to your last message. tag:makezine.com,2005:msg.4604 2013-03-11T23:36Z 2013-03-11T23:36Z Laura Cochrane yes the screen is removed before use. Yes your ideas are good, that's the way to do it. This way is just the easiest quickest way for me to get a bugproof poo barrel right now. The diagram of the urine diverting funnel in this issue is incorrect, it should be smaller and off-center. I don't use a funnel with mine, I pee separately. thanks for the comment! happy humanuring! tim tag:makezine.com,2005:msg.4602 2013-03-09T15:39Z 2013-03-09T15:38Z tim_anderson Thanks for the pics. That's a VERY nice build. I like the rocker power switch. Looks like you have a couple more circuit boards on deck for future amps. The chip can be run from a single supply rather than a bipolar one. It requires a coupling capacitor at the output to block the DC. Also the input has to be referenced to 1/2 of the B+ voltage rather than to ground. If you Google up the data sheet for the chip you'll find 'single supply' applications in it. There's quite a bit more circuitry but it's doable. tag:makezine.com,2005:msg.4601 2013-02-28T09:59Z 2013-02-28T09:59Z BAUHAUSLER I wanted to post a pic of my amp. http://www.flickr.com/photos/marsvsstarwars/8513857201/ and say how good it really sounds. Also Ross, I posted last year a question about powering the amp with 18 volt power tool batteries. As you replied, I would need 2 batts. to make up the bipolar power supply. So I've been doing a little online research, and found some info that one could power a bipolar P.S. with one batt. like guitar effects peddles, which run on 9 volt batts. Anyhow if you have any info on how i could make this amp work with one 18 volt battery, appreciate the help. It may well be its not worth the effort, i don't know. I get this op- amp chip needs a bi polar P.S. There must be a way to do it. By the way, its been a real learning experience, and am working on my next amp, built into a 4" pvc conduit, with speakers on both ends. tag:makezine.com,2005:msg.4600 2013-02-28T02:13Z 2013-02-28T02:12Z simcain
