But either way, I can''t see a simpler circuit that would allow the switch to be controlled by a microprocessor. For example, to turn the P-channel MOSFET on, when the 2 V-50 V rail is at 2 V, the gate would have to be pulled down to around -2 V or lower.
Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as "Cupellation"*. These processes are
Remove all parts of a computer that contain gold and burn them in a large metal barrel. You''ll be able to recover only the charred pieces or chars from the ashes since they''re made of metal. Usually, professional gold extractors will weigh the char volume, estimate the amount of gold and pay for completing half the process.

The reality is that no soldering operation produces perfect assemblies every time. Even the highest quality components fail from time-to-time. That''s why understanding the best rework and repair methods and materials is so important for those who manufacture
· Abstract. The biosorption of gold from discarded computer microprocessor (DCM) leachate solutions was studied using chitin as a biosorbent. The DCM components were leached with thiourea solutions, and two procedures were tested for recovery of gold from the leachates: (1) biosorption and (2) precipitation followed by biosorption.

· Shake the container until the gold is exposed at the bottom of the pan. While still holding the pan under the water, gently shake it to shift the rock powder. Expect the particles that aren''t gold to float away and mix into the water.
· The polishing compound will remove the gold off the pieces and will leave the metal under it unharmed and shiney in the process. A dremel tool with a couple of different shapes and sizes buffer wheels is good for small areas.
· Gold is usually extracted from ceramic IC chips in two steps: The ceramic casing is mechanically removed from the outside of the chip. This often involves manual work to physically split the ceramic "shell" of the chip and expose the microchip within.
_ Modern computer chips manufactured after 1998 have very little gold content in them because most CPU''s no longer use solid gold wire bonding technology or gold-plated lids in their packaging. For example, the Intel Pentium 4 Microprocessor came in an organic (non ceramic) package with a nickle - plated copper lid, & it did not use gold wire internally to attach the silicon chip to it''s package.
