My Virtual Life

Fig 1: Three experiment--two with the samsung remote on the left, one with the Radio Shack remote on the right--to control a  +Adafruit In...

I've been away from this book (Make: Electronics by  +charles platt  ) for a couple of months.  I have really enjoyed the experiments, a...

This chapter ends with the concept for another robot, this time one that responds to light with photoresistors. I decided not to go all the ...

The saga continues... I put the pieces of the cart together as shown here: I attached the hinge to the body only to expand the pilot ho...

3rd attempt at the cart.  Used a hand saw this time, and my handy drill. I marked Xs on the pieces I want to cut out to remind me what I...

So, carpentry and fabrication are not my strong suits. Evidently I'm not real strong on following directions, either. Anyway, this i...

I'm ready to start on this. First step was to gather the materials.  The parts list on page 268 is incomplete, although on p. 276 there...

This is one of those things I've wanted to do for over 55 years.  If I'd only had more motivation and more support, I would have.  W...

From Make: Electronics, by Charles Platt. Sebastopol, CA: Maker Media, Inc, 2009, p 259. In Experiment 30, we are creating distortion...

Note: first, apologies to  +Eric Buijs  who noted that the TEA2025B runs hot at 9V.  I either did not notice or did not perceive that in ...

I know very little about audio, etc., so this experiment is very interesting to me.  When I was 10-12 years old, I read about people maki...

These three experiments, like #25, are pretty short. Since they're related, I decided to do them all together.  I thought of doing this ...

Experiment 25 is a very simple grade school experiment on electricity and magnetism. Charles includes it because it's neat and because...

I've been away, and recovering from being away, for a couple of weeks, so I'm just getting back to my journey of discovery with Char...

This is an interesting and challenging experiment. Challenging because I sometimes have problems getting from schematics to breadboards, an...

This experiment is deceptively straightforward. The only issue I had was a bad chip. First, I mentioned in the last experiment that the sl...

After the last experiment this one is pretty straightforward. One 74HC32 quad OR chip, 2 timers, one SPDT switch, 2 tactile buttons, 2 LEDs,...

Getting past the fact that the 555 won't supply enough voltage, ever, the next question is how can we amplify it. The answer is with a t...

As I noted that 555 Output Pin 3 voltage will be lower than the Vcc on Power Pin 8 by up to 1.7V.  That probably should have been the first ...

This has taken a while. Snow, family visiting, setting up my new generator, an fuel oil spill in my basement, and other events have dominate...
