Wombat Pulsed Oscillation

[Tec]

The ‘Wombat Pulsed Oscillation’ uses a mono coil and capacitor (tank circuit) oscillating freely, similar to a good old BFO or a ‘VLF’ detector.


Unlike a BFO or VLF detector, it uses a ‘time of flight’ chip, the TDC7200, to measure frequency and amplitude change with...

I'm repairing an XP ADX 150 mainboard. The 10-pin IC located right next to the crystal , burned out after the coil cable was damaged.

The original IC markings are factory erased by XP.

Here are the PCB pin measurements without the IC installed:...

Aziz and myself have collaborated to bring you SPULE32 which is Aziz's coil modelling software.
He has kindly provided the original source code ( C, C++, ASM ) which originally was built for windows and I ( with AI help ) have ported to Javascript.
So to be clear Aziz did all the work and...

I have invented a most powerful drawing transfer method (for fine arts) a couple of years ago and it isn't published yet.
So all the...

The mono loops have a TX and RX winding which are fully coupled and not inductively balanced. The Tx/Rx are wound together. The Tx is 18awg tin plate stranded with pvc insulation(258uH 0.6R). The Rx is about 30awg single strand teflon or kynar insulation(228uH 6.0R). Inside the coil is a protection...

Thought i would share with you all the full schematics i made up for
the M/lab SD2000.Over the years with all the fiddling on the 2000
i did and the resulting hand drawn schematics,why not do the whole
thing and present it to those that have an interest.
I would like to give...
