Does anyone have any Ideas to incorporate the small projects into PH on any of these pages?
http://www.geocities.com/kiwi_36_nz/tlog/tlog.htm
or better yet:
http://www.cesko.host.sk/GamePortTemp_eng.htm
or how to get the illumination level of an LDR connected to the game port.... the hardware is no problem, the software is my problem...
with 4 temp.measurements I can e.g. measure the watertemp. of my solarboiler, as well as the Central heating and the temp in the living room and the temp. outside

Peter,
I checked out the sites above and at first glance, PowerHome should be able to be interfaced several different ways.
The first site showed the temp sensor going to a parallel port. You should be able to write a simple program in VB to monitor this and then using Windows Messaging, send the temperature to PowerHome when a change is detected or at regular intervals (You would need Windows 9X or additional software to directly monitor the parallel port for NT and 2000). It also mentioned the sensor being interfaced with a serial port and you could use the internal COM routines within PowerHome for this one.
At the second site, it would probably be even easier. The author says that source code as well as a DLL is available to monitor the 4 temp sensor on the game port. You could wrap this DLL in a simple VB program and then use Windows Messaging to communicate with PowerHome. It also said that it included an internal HTTP server. With this approach, you could use PowerHome's ph_geturl function to query the temp info. One last approach would be to use the supplied software that writes to a CSV file and then read this into PowerHome for temperature parsing.
Dave.

Or, since Dave is working very, very hard on the K8000 support, you could use the analog in's on the Velleman K8000 card in the very, very near future, right Dave

That is correct .
I actually finished my K8000 two nights ago  (it was a long time coming). Ive coded up the initial communications and hope to test soon. I didnt have a 25 pin male to 25 pin female cable, so had to go out and buy one last night. Couldnt find one, so ended up getting a parallel transfer cable (laplink??) male to male and a gender-bender. I got to thinking however that it may not be a straight-through cable. I'll break out the multimeter and test it tonight.
Dave.

Since PH is running on a P100 with 2 comports and one is in use for the mouse, leaves just one, this is needed for the CM11a.....damn, no comports left

Well I always choose the easy way, I have taken the hard way long enough ...However like I said: programming is not my strongest point (to say the least) I can do a little bit with the formula functions in PH (Newbie right...) but VB is another.... When I have completed the hardware I'll try to make it work woth the internal http like you mentioned. But if anyone has the time to scrap a VB script together, that would really be a barnburner for me... (silent hint) Perhaps I should buy the book "VB for dummies" or something like that.... All the post you and Tony make, I read carefully, because there's always something I can learn....

Definately buy the book...you'll probably actually find it fun . Once you've put the hardware together, let me know and I'll whip up a little something for you in VB.
Dave.

Tony,
Not sure if you were asking about the K8000 or not, but if you were, the best price I could find was about $125.00 here: http://store.qkits.com/moreinfo.cfm/k8000

Didi,
Well, that damn parallel laplink cable wont work  . However, I did finally come across a straight through cable and was able to use that.
The good news....it works!! Was able to test my initial coding and I was successfully able to turn on/off my digital outputs. I am stoked  !! I was able to prove that I didnt make any mistakes in my assembly and was able to get my own I2C routines going. It's a good thing I got the kit because without having the hardware there, I would never have been able to tune my programming to get it working right. I was able snap on 16 digital outputs in less than a blink of an eye...and that was turning them on individually and not a whole chip at a time.
Anyways, thought I would let you know the great news and that progress is being made .
Dave.

Dave: I searched over here for the parts, one shop had the guts to ask $27,- each! However now I have ordered them on the internet (conrad) and they'll be here next Monday. So before Monday the VB doesn't have to be ready....At conrad they still are $7,- each but that is still cheaper then $27,- right

Thanx dave, could you please comment in the VB so I can study it....the hext project has been given by my wife: She wants a firealarm to be installed with smokealarms and a panicbutton so that all shutters open when there's an alarm. So that will be my next project when this one is finished. I've already got some ideas but I'll start a new thread when the thermometer is up and running!
