als je ze koopt bij hantz in duitsland, die leveren ook in nederland, zijn
ze
ietsje duurder 32 euro.
hantz, is een gerenomeerd bedrijf.
de persoon die ze aanbood op ebay, is ook van hantz.

Aha, ik zie het. Tja, de wet van de grote getallen geldt hier. Als ik
10.000 bluetooth multiplexers ga maken, kan ik daarmee concurreren. Let
wel: de goedkope modules van Hantz zijn class 2 met een bereik van 10 meter.
De modules in de MiniPlex-4xBT zijn class 1, met een bereik van 100 meter.
Dat maakt qua prijs ook een wezenlijk verschil.

Hi all,
Our Bluetooth enabled multiplexers have finally seen the light.
See www.shipmodul.com for more details.

Definitely an interesting product, wrote some thoughts about it on my
weblog, www.panbo.com/yae. How do you see Zigbee (www.zigbee.org) and
NMEA 2000 fitting into this? Will they obsolete your products?

I don't think so. Not for the near future. Like I mentioned in my other
post, NMEA2000 is quite costly. It is just too darn simple to put a simple
serial interface on a device.

As for ZigBee, I'll have to investigate that one. It is of course not such a
widespread standard as Bluetooth, but it has it merits. But I'll always have
my doubt about equipping every sensor with a wireless link. As long as you
have to power something with a wire, you can also transport data over that
wire, eliminating the need for wireless.

Yes, I understand that last point, but then again, Zigbee was
developed with exactly that requirement in mind. It's extremely
efficient with power so that it can be used for a long time running on
a battery, or on a few solar cells. This would probably not be
feasible with Bluetooth. Although they are now developing a
low-powered version of Bluetooth to deal with this problem...
