As the title states, has anyone tried this iron? You can see it at http://www.web-tronics.com/lesostwdic.html. It's somewhat similar to the Hakko clone, but has an iron similar to Metcal irons, and is a higher wattage, at 70watts. Looks like it could be a great iron, however I'm not too sure of...

I'm building a Dynalo, and right now I'm working on designing a low-cost but reasonably good power supply for it. I've attached a schematic of a tracking voltage regulator from the datasheet for a LM78XX regulator IC. Now, instead of using that IC, I plan to substitute a TI uA723 regulator which...

Ok, I've already made a Meta with a OPA2132, now I'm trtrying to make one with a AD8620. I made an entire new Meta with the 8620, but the left channel didn't work at all. Next I used another 8620 and installed in in my original amp, after removing the OPA2132. Again, the left channel didn't...

I'm attempting to make a smaller version of the Meta, that will be rechargleable as well. I'm planning on using 2 3.6v Lithium Ion batteries, so the voltage would be 7.2v. First of all, would the AD8620 work with this voltage? If not, what other SMD mount chip would? Also, are there any SMD...
