Here are some pictures of Bots built by others following my tutorial or ideas:

Click on the pictures to see them FULL-SIZE.

Click on the pic to see "Frog," built by Justin Woodman, using this tutorial. Good job, Justin!

Here's a very clean design built by Harold Ilano using a PCB Kit from Radio Shack. Very clean construction and aesthetics. Notice the heatshrink on the FLEDs too. Very nice job, Harold.

Here's Adam Kosick's new Fred. Click on the pics to make them bigger. Notice the electrolythic timing caps. Neat eh?

Here's Garibaldi Pineda Garcia's new Fred and Battery-Vore. Click on the pics to make them bigger.

Here's Justin Zoll's Photopopper. Notice the two solar cells... Click on the pics to make them bigger.

Here's Joey Caron's BatteryVore (Battery not shown). Nice and clean construction... Click on the pics to make them bigger.


I decided to post some of the e-mails I get from people about this website and tutorial. I didn't want to do it at first so as to not sound like I was bragging. I've deletted many good feedback e-mails so I just started fresh here.
I want to thank all of you who've sent me e-mails thanking me for the website and the tutorial because this has taken me a lot of time and hard work.
So, hoping not to sound stupid, here's the Feedback:

Hi, My name is Justin and I am a 14 year old who lives in NY. This e-mail is kinda pointless but I just thought I'd thank you for your photopopper tutorial. I'm really interested in robotics and particularly BEAM so it was very helpfull. It was my first BEAM bot and of all the tutorials I looked at yours was the most clear and conciece. The thing that surprised me is that my bot actually worked on my first try! Please keep up the good work and thanks for such a great tutorial, mabe now I'l try something harder!



Hi ray Last time i said that my bot was photophobic but i inversed the motors leads and now it can move toward light. It don't follow the light but it can reach the brigtest light spot... Tanks for all your help and support and for posting my pic on your site here is another one showing the top. I bought my caps at radioshack and they are soooo big Ill try other motors with the same circuit soon I plan to use geared motors...

Thanks a lot.
Joey Caron


I just wanted to drop you a letter of thanks for your informative web site.
I printed and built a 'FRED' without any problems at all ! When I connected the solar panel, it came to life and works perfectly!!
It took about 4 hours in all.
I since then built another one (took 3 hours) and it too worked perfectly the first time.
We have a foreign exchange student from Belgium going to our High School, and he was simply fascinated by my demo of the two bots. Turns out, he is going into industrial engineering, and wants me to mentor him in the making of these robots for a school project.
I took the bot to Radio Shack, where I bought most of the parts, and they too were impressed.
I'm looking forward to the finishing of your other tutorials, in which I give FULL credit for my success and rekindling of this fascinating hobby.
Thank you very much.

First off I want to say how much I enjoyed your site. I'm newish to Beam and electronics in general so I've found your site very helpful.
I purchased and built a few solarbotics kits, photopopper, solar roller, miniball (bought awhile ago). I've also freeformed a symet and a Chiu photovore.
Anyways I look forward to you finishing your walker tutorial. I would like to build something similar to your grasshopper 2.5.
Thanks and keep up the good work.
