WTB UK – Douk Audio Two Board Oscilloscope Clock Kit
« on: October 20, 2020, 11:49:43 am »
Hi!

Is there any EEV Blog Forum Member who managed to get one of the "Douk Audio" 8SJ31J Two Board Oscilloscope Clock Kits willing to sell one to me, built or unbuilt, (CRT not absolutely needed but useful), please?
As a minimum I would need the two PCBs, micro and power supply transformer!

I've tried to buy one from every single eBay, Shopping and Amazon listing I can find and every seller has come up with "no stock!", sometimes over a month after the original purchase date!

(Why don't these sellers remove listings completely when they're sold out?!)

As an alternative, if anyone has one of these kits but wishes to keep it, can they send me a high–quality photo of the bottom (copper) side of each PCB and a copy of the Assembly Manual please?

I can trace the component positions and some of the tracks using Sprint Layout software, working out the exact connections from the circuit diagram, or drawing my own from the photos!

The transformer I can probably make at a pinch once I know the dimensions!

Also needed is the full micro type number – I can re–compile the "SC200" design code provided to suit the micro used!

Any reasonable price paid and postage reimbursed!

Hi!

That's excellent – source–code and hex as an additional bonus!

The seller of the Original eBay Listing provided top views of the blank PCBs in high enough resolution to import into Sprint Layout using the "Scanned Copy" function, from these and the circuit details you provided I can complete a prototype design apart from the "T–SC1" – if anyone knows where I can buy this transformer please let me know!

Thank you for your time to furnish me with the details & Code Sir!

Another o-clock kit:

It's more of a raster display than "vector graphics".
