Well, got it together. Hopefully it will work.

My first attempt at surface mount soldering

Not too bad, both harder and easier than I expected in certain ways.

Only screwed up one component. 🙂

Review of the Chaney 20 Watt Mono Amp Kit – C6444

by @ 11:03 am. Filed under Component Electronics, Reviews, Technology

So I needed a mono amplifier, I decided to just pickup this kit: http://www.chaneyelectronicsstore.com/servlet/the-121/20-Watt-RMS-Mono/Detail

Chaney C6444 Mono Amp Kit

Which I must say had some good and bad effects on my project.

#1 The PCB. I hate to start with a negative but this one is a glaring disaster. The single-sided circuit board was simply horrible. It had no information printed on it whatsoever and relied on the instructions for all placements and orientations. (It did not even have information as to what wire connections went where, you’ll notice my sharpie markings)

#2 The kit came with a much smaller heatsink which was extruded aluminum rather than the sheet-metal one that appears in the sales shot. This is fine for my uses as i’m putting the thing into a box with multiple other components.

#3 The instructions. Three pages, color, very concise.

#4 The Pot. Too short, the knob I put on it barely fits at all, this could have been far better.

#5 The included wire. It was red. Why one color of wire was included in a kit that needed 6 different wire connections is beyond me, I guess they just figure that you will connect the same red wire to your unmarked power connections and somehow remember which is which.

The kit does what it says it will do, but in the end I was not very happy with the overall construction and contents of it. A friends suggestion made it sound FAR better however.

C6444 Improvement

This consists of one 10uH inductor, 1 560 Ohm Resistor and 1 10uF Capacitor (Need not be 100v). Put them together as shown in the “+ Input” line between your source and the board. I found the new sound to be much deeper and full.

Good luck.

All accelerometers are not created equal.

by @ 8:52 pm. Filed under Component Electronics, Personal, Technology

So lately i’ve been playing around with electronics parts, and I stumbled upon a post that said there was a really good accelerometer in the Wii Nunchuk controller.

Not wanting to let a good thing pass me by I ordered a cheap one on Ebay for $5. Well, that was my first mistake.

The data was horrible, totally substandard, today I bought a true Nintendo brand nunchuk used for $15 and well, the data speaks for itself.

Lesson learned, I now wonder what other controller devices have such awful components in them that we never “see” outside the packages, nor get a look at the raw data.
