Yet another dumb ST to VGA adaptor, take 2

Postby mpattonm » Tue Aug 22, 2017 7:36 pm

Hello,

as promissed, I have manufactured another batch of "Yet another dumb ST to VGA adaptor". Actually, in the process I have also comitted few slight changes on the design too. So whats new compared to original design (as seen here viewtopic.php?f=15&t=31929)?

- the switch lever is now facing upwards so its position can be seen and its easier to operate from above
- the bottom of the PCB is now filled with ground plane. At these frequencies its not really a design requirement, but it helps the assemby a bit and actually looks better.
- there are now (empty) solderpads that you can use to add resistors on RGB signal paths, should you ever need it. Simply cut the 0 ohm track between the two solderpads on each signal track and solder on the resistor with value of your choice. Solderpads are visibly marked with corresponding R G B letters.
- on top of already available solderpad for mono audio-out there is now one for composite video-out as well. They both share common ground. You can eventually attach a small cable or pinheader on to these, if required.
- minor changes in layout to allow use of (in near future) produced CNC cases
- more logical HI - LOW/MED switch printing placement. Just cosmetics...

And as a last time, I have few pieces left for anyone, who is interested. Price remains the same:
DYI kit is 9 EUR /10 USD
assembled version is +5 EUR /+6 USD
P&P 3.50 EUR /4 USD for european shipments, or 4.50 EUR /5.50 USD anywhere else in a world, shipped via priority mail postal service.

Please PM me, if you are interested.

Just a heads up, 2 last units are left from this batch. All the rest is either shipped/sold or on confirmed order.

All gone, sorry to Baert and others who could not get one. Again, I could eventually make some more.

Just a last handful of ST2VGA adaptors from second batch manufactured, tested and ready to be shipped out on Monday.Third mfg batch will follow some day soon.

What you might notice is that I have changed clip-on support of VGA connector for even more robust screw-on type. Not that I would have a single complain till now, its just to satisfy my hunt for perfection. At least for a while :) On the other hand, I would not dare to sell an assembled unit which has VGA connector only resting on its solder joints. They could break off easily after some re-plug cycles.
