Product BOK-11131 | about 3 months ago
Of the series, I would have to suggest you get this one. It is by far the most useful and practical. It also makes a great accompaniment to the “Getting Started in Electronics” Mims Book (BOK-10764). And it’s the only one I still keep handy. Start with “Getting Started…” then build using “Timer, OpAmp…”. You will often find that a circuit you build does not work quite the way other resources suggest. Mims' circuits simply work. He makes it easy for you to modify and combine the many circuits, included in the book, for your own needs. He even provides IC part numbers. I’ve personally found the LM324 quad op-amp to be most user friendly for use with this book. Half of my Mobot’s circuit solutions were found in this book. Happy Hacking!

Call Guinness. It’s time they added a section for the hand and re-flow soldering world records. And that means it’s also time to track down the world’s largest hot-plate :)

Anyone else seeing failures here? Many of them I bought seem to only switch states.. some times.

Yeah! Thank you for saving me the time, Nest dudes :) I’ve had this project on my mind for a while. Guess i can check that one off the list./

FPGA’s Rock my world! Imagine the ability to run bits of your code in either parallel or series.. mixing it up however you please. No longer must you run every function in your code one-at-a-time. FPGA’s allow you to, for example, read 20 different sensors, and dynamically control 10 different actuators, at the same time. Buah-hahaha! Love it. [insidious smile, heart races, crazy eyes] Can you feel the POWER? Can you?

Solarbotics performs their own Drop Test, in response: http://www.youtube.com/watch?feature=player_embedded&v=MJT3_D_cZsc Why aren’t we using quality materials, folks? Personally, I would pay an extra buck to ensure the robustness of my $100+ robot.. which I hope to be able to use again and again and again,…

Guys, you continue to amaze me with your.. customer service and willingness to please / break things.
Don’t get me wrong. This still looks like a GREAT LITTLE PLATFORM, especially for a $15 kit. You could expect to put in ~$35+ and 4 hours of work to make a similar one from scratch.
Just don’t plan on any high jumps or parachute drops with this baby. Keep it on the road.
On another note, has anyone figured out how to laser cut Lexan? It does now come in tinted colors. You could drop test a good Lexan bot frame from 100 feet. It’s also a great material to machine / work with. I

Is it loaded with Tetris? Seriously. Some are :)
