This is a quick post to update any followers of the site. I spent the beginning of the week installing laminate floors in my house. I neglected most of my college course work, and now I’m trying to catch up.
I’m working on a 4 speaker Cigar Box Amp. It’ll make it to eBay sometime next week. It’s a working prototype. The electronics are basically the same except that I’m adding an external power jack, a hard battery clip, and a front cover that may or may not look good. I covered most of the front with fabric to cover the speaker holes. I’ll have pictures up next week in the Cigar Box Photo album. I’m also removing the power switch and using a stereo input jack as the switch, and I’ve added an LED to signify that the power is on.
The suitcase amp is still under construction. I do not like version 1.1, and I’m probably going to scrap the 2 watt version for now. It has a horrible “hummmm” when used with wall-warts, and I probably need to add some smoothing capabilities to the incoming power. I am going to test it out with the LM386 circuit and see how that sounds.
That’s about it for Tech-tut.com’s latest updates. I haven’t said this in a while but remember that “it’s more than just a project.”
