Open Discussion / PCB etching question

Getting ready to etch first .  I've etched enclosures with ferric chloride.  Will the copper etch quicker or slower than the aluminum?

Open Discussion / Favorite Slow Downer iApp?
« on: August 13, 2013, 10:32:41 AM »
Downloaded Anytune free.  The $14.99 version seems very feature rich but I hesitate to recommend a $15 app to my students.  Anybody have any input or alternatives?

Build Reports / First Strip Board Build - Triple 3 OD
« on: July 19, 2013, 04:19:24 PM »
Based on the Lovepedal Eternity layout from tagboardeffects. Probably not an original idea but I put the LED in a 2x8 piece of vero with the CLR and hot glued it to the enclosure (don't particularly care for soldering wire to the LED leads:)
Fired up first time!

Open Discussion / Is a LM7805 the same as a L7805?
« on: June 18, 2013, 11:05:44 PM »
I placed an order for a LM7805 and received a bag labeled L7805CV.  When I double checked Tayda's website and my old order, it read "LM7805 L7805 7805".  Are these all one in the same.  There seems to be different spec sheets floating around the web.  Is it a matter of different manufacturers?

General Questions / Noob Solder question
« on: May 17, 2013, 05:54:17 PM »
I'm having a little issue with my soldering iron.  It's not heating evenly across the end.  It tried to go ahead and use it.  My question is, can the solder touch on adjacent components.  The top side looks fine.
