Ultimate Bandido PCB?

[driscoll]

Good evening M. Magman116,

Your promises are very interesting, but for now we could not appreciate your talent.

Where are your shematics ?

Where are your PCB's ?

Regards

[Magman116]

The schematics are only partly completed electronically. My Partner has them hand drawn right now. I guess I can just scan them and post the scans.

Let me see what I can do today.

Here are the hand drawn schematics for the Half-Dime.

Thank you,

Indeed, it is interesting.

A quartz controlled transmitter (like Fisher), LF444 and LM324, a lot of voltage reference, i like it ...

Bests regards.

VERY interesting, low noise design. I VERY much like the receive amplifier. Good impedence match to the coil and following stages I think.

[Magman116]

The transmit oscillator can be changed to operate at any desired frequency. Initially it ran at 15Khz, but was then changed to run at 8.192kHz with a custom 8" or 6" concentric coil. The first build used a Garrett Ground Hog II concentric coil and could get a dime at about 16".

The LM394 is critical to a low noise preamp and is used in many of our designs.

Nexus ancestor.

Why do you think this is an ancestor of Nexus?

Why do you think this is an ancestor of Nexus?

Cause I am reading some treads here that discuss Nexus. Some hints of Nexus author about schematic can lead to this solutions or opposite, who know? More provokative question than one claim.

PCB etc

Magman116, you mentioned about making PCB's for this, and making an offer... have you considered this any further, and at what price range ?

Magman rode off into the sunset

Here today, gone tomorrow...the circus left town.

Yes.. only some traces left

shame this project stopped i was interested in buying a bandido in kit form (readymade pcb )for the sole reason do not know how to make pcbs and not got the equiptment to make 1
