Hello!
Something on the order of three weeks ago, I said that I would start posting every Tuesday and Thursday. Seeing as this has been my only post since then, we can all see how we’ll that worked out.
At any rate, on to today’s topic – high- and low-pass RC filters.

Hello!
I was recently working on homework for electronics class when I decided to try to solve an interesting circuit, which is a slightly modified resistor bridge circuit:
All of my first inclinations on how to solve for the resistance were incorrect, and this circuit became a good self-introduction to Thevenin equivalent circuits. Read on for the full solution.

Ah! I keep on forgetting to post!
I’d just like to point out that I’ve added a new feature. I have a little dinosaur on my desk and I’ve started making him hold quotes. You can see today’s quote on the sidebar and an archive in the “Quotes” tab above.
Thanks for reading!
DIY Oscilloscope – Part 2
Posted by bluepichu in DIY Oscilloscope, Electronics, Project on July 28, 2012
Hello again!
This is a continuation of part 1 from yesterday. (Speaking of which, it seems to be a very popular post – thanks everyone!)
This time I’m going to cover the range fitting circuit.
DIY Oscilloscope – Part 1

I haven’t posted in, what, a whole week?
To make up for this, I’m going to try to do a post every day until Monday. So anyway, here goes with the first one.

It’s been so long since I posted!
I recently purchased two Boarduinos from adafruit for an infrared control project I’ve been working on. However, I found it quite annoying to get the correct frequency for a square wave so that the IR detector would get the signal.
After a long day of searching, I came across a lot of sites including libraries that would (supposedly) do it for you and a lot about using the Arduino’s built-in timers and pulse-width modification (PWM). Since I needed 56 kHz, I had to combine a lot of the info I found to make it work, but in the end I got it! Here I’m going to show how you can use the Arduino’s timers to make a square wave of any frequency quickly and easily.
