Basic 74AC240 Bicore

I wanted to upgrade him with a solar engine, and I decided on the FRED solar engine.  Originally, I was going to build the FLED solar engine, but it is so inefficent it drove my perfectionist side insane.  Sooooo, I ended up spending half an hour getting this circuit to work, and I suceeded in getting it to pulse in direct sunlight and under an incandescent desk lamp.  The FLED couldn't even pulse with the light bulb literally on top of the solar cell!

I included a video of it pulsing wherever videos I embed in my posts go/are.

Driving a motor with solar cells (without a solar engine)

What I want to do is this: I have a basic bicore hooked up to a vibration motor.  He kind of flops around, but it isn't totally random.  Anyway, I was wondering how I could power him with some solar cells that I have without using a solar engine.  If that's possible, I would really like to hear some ideas.

A long, long time ago, I went to Maker Faire NYC. To be precise, 4 months ago in September. While at Maker Faire, I bought a Spurtbot kit from ignoblegnome, and I … Read more

Miller engine .... but it dose work

Ok it looks a mess but it dose Work .... So why am i posting this .... couple of reasons ... first off its my first proper working circuit and i have a few questions about it.

As i have  very little to work with im delighted to get this to work (hopefully that will be changing shortly .... just have to get paypal sorted with my bank and ready to order a few bits and pieces.)

Beam photovore problem

Ok so I made this beam photovore robot using an online tutorial (google: rays beam robots) and after I completed it only one motor moves. Watch my video below.
This is my first Pummer I have successfully build and I am pleased with the work. It is a simple two LED pummer. Took me nearly 10 hours to complete due to the fact … Read more

stop a capacitor charging when full

i a ma a complete beginner and i am reading a book about beam bots (mostly) and i had an idea for a beam bot which probably wont work and i might not build but i decided to try and draw a schematic anyway. the idea is it goes towards light and when there is lot of light it starts to charge a very large capacitor before going back to following light. when it detects vibration(can you get vibration sensors?) it uses the power from the large capacitor  to run until there is a lot less light ( ie it is under something) and stay until the vibration has gone.

This robot is a free formed robot that I made, its like my symet but better. It uses a simple analog circuit that stores up electricity until there's enough to make … Read more

Detecting laser beams?

Using an Arduino, I guess I would modulate (PWM) the laser module and have the photocell light sensor pick up the frequency. Would this work?
