Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

  Bryan1 said   Hi CC,
The simmstick 30 pin buss was a great idea and it was great to see your cgmstick included that concept. Now with your new board by putting a 30 pin header on the end of the board would allow users to put a header on say some veroboard and gain access to the not only the Arduino buss but also other pins that are left available. That way users that want to use the Arduino buss can make their own boards easily by using a 30 pin header and not have to pay $$$ for shields etc.


Bryan:

I'm not sure if I am interpreting your suggestion correctly or not. I had considered sending all of the I/O pins (from the MMBasic perspective) to a single row of pins along the edge of the see of holes. That ended up making for a messy layout.

The 'original' MM I/O pins are available at the duplicated 2x13 connector at the top. The 'extra/Arduino' pins are located in the shield pattern. You would need to use jumper wires to run these signals into the sea of holes, but you could duplicate something much like the Simmstick layout there.

I'll be selling a 12V "wall wart" power supply for the CGCOLORMAX (ColorMax). If I pick a supply that has a "barrel" connector on the end is that preferable over picking one that has just two bare wires?

Barrel connector:



The input for the ColorMax power supply will accept 8V - 18V DC. A 9V wall wart will work, if you have your own. I'll have a 12V one for sale. Not sure what the rating will be for current, yet.

The power supply will provide up to 75 mA for the 3.3V power line and more than 200 mA on the 5V line for the circuits that you add to the board.

For me I would prefer the barrel connector if that is what the power input socket on the CGCOLORMAX requires. Of more concern is the input voltage and pin configuration for the wall socket. I know Australia is different from the USA in both of those respects and other markets probably have other variations.

Hmmm. Excellent point Bob. I have designed devices for 220V/50Hz and have specified adapters with various prongs on them for 'mains' voltage. I'm certainly familiar with that. I would like to be able to supply a modular wall wort that works in several countries.

I'll see what I can find. The first one out the chute might be US-centric with a universal one to follow.

Thank you for expressing this concern - it helps.

The nearest thing I have seen to a universal wall wart was on my Western Digital TV Live media player. It came with a replaceable, clip on set of pins to suit the Australian wall socket. Not sure whether the input voltage was universal (100-240 VAC 50-60Hz). I can't easily get a look at it as it is "buried" at the back of the stand for the very heavy (80Kg) plasma TV.

That is exactly what I hope to find with my supplier.

I have one that is a switcher and 5V/250mA out somewhere in my office. It would be something like that.Edited by CircuitGizmos 2012-10-05

I will buy one, but I'd prefer to wait until the plastic case is also available so I can get them shipped at the same time.

Waiting with baited breath.... hey - what do you expect from someone with a fish as an avatar?

Good find there Don. I found the one Chuck referred to and it was variously AU$20 to $30 + shipping. Side benefit also, this one supplies enough power for welding small jobs (slight exaggeration, lol).

Thanks Bob, these are also a HP surplus product, but there are many similar products, at similar prices.

Would cost you more than this normally for postage. Let the Chinese government pay for postage on power supplies I figure.

Don, what's the description for a power cord suitable for that power supply. Deals Ex may have them too. I tried searching but I don't know the right words.

First hit I found:
http://tinyurl.com/97cpj58



Product Description
IEC-C7 Appliance Power Cord - 2m Length

2-core light duty power cord as used on some small appliances and laptop power supplies

Fitted with an IEC C7 / Figure 8 connector and Australian 2-pin mains plug with insulated pins compliant with AS/NZS3112.

==============================

You can get them in local areas with local AC standard plugs on the end. I'll have a bet that most users will have a box with a few in it.

see:

I figure if you haven't got one, any cash converter store should, perhaps even you local hardware etc.

Here's another option.
You can pick the plug you need for your country from the drop down menu.
$4.95 + $7.25 shipping to Western Australia.

Those are some excellent places to pick up country-specific wall-wart power supplies.

COMPLETELY different from 5.5mm. Beware!!

(Sarcasm, just in case anyone wonders.)

I wonder why they can't just say 5.5? Do they not know?

I'll bet they don't know that the center post is 2.1 or 2.5.

The label:




I doubt it is CE and/or UL.

And that's how they keep anyone from plugging 12V into something that wants only 9V.

The 9V is 5.46mm, the 12V is 5.47mm.

There is NO POSSIBLE WAY that the 5.47mm 12V plug can be used in a 5.46mm jack. That 0.01 is the safety.
