Datak Direct Etch Printed Circuit Board Etch Kit Here is everything you need to make printed circuit boards with no separate artwork. You wire the actual circuit by rubbing down etch resistant component patters right on the copper-clad board. Connect the patters with the etch resist tape or dry transfer resist traces, etch in ferric chloride solution and in a few minutes the board can be drilled, loaded and in operation.
6' MAGNETIC TRANSDUCER MAGNETIC ELECTRODE / MAGNETIC PROBE MAGNETIC FIELD PROBE / BRAIN PROBE BRAINWAVE ELECTRODE, 12mH, 25 Ohm New old stock (NOS). These magnetic transducers / magnetic probes / magnetic electrodes / magnetic field probes / brainwave electrodes / brain probes can be used for both detecting/receiving and transmitting magnetic fields and as a small electromagnets, depending upon the piece of equipment it is connected to (under 250ma current).
