Getting In Touch with Hobby Lobby
The internet and email have changed the way that many people communicate. Unfortunately, it can sometimes lead to miss communications, as has happened with some of Hobby Lobby's valued customers. In speaking with Jim Martin, he noted that the best way to get directly to Hobby Lobby for your answers to questions about products, or technical questions, is to use the address that goes directly to them at 74164.2423@compuserve.com
By using this address, instead of the reply via their internet address at: http://www.hobby-lobby.com , you will be sure that the HL staff will answer your question promptly.

build yourself project) costs only $100 incl. the LCD readout and the 3 basic sensors! (volts, Amps and Rpm)
I have just asked for more information on this little marvel, because I want to build one!
I think that Milan can supply the circuit boards and the microcontroller chip which has all the functions programmed in it, as well as a list of the other necessary parts.
I am not sure whether any info is available in English yet. There are rumours that one is being built for evaluation in a UK modelling magazine.
Happy flying! - Hannes
This sounds pretty good, and the price is certainly reasonable. I hope to be reporting soon on the American made controller that will also do this. Hey, Pat, any chance of getting one soon? km

Hi Ken!
My name is Hannes Steets and I live in England,
I usually download the brilliant Ampeer Newsletter from the Web and enjoy it very much.
I just reread the November '97 issue and stumbled over what you wrote there:
"I
have a challenge for all of you "electronics" experts out there. Design a light-weight unit
>to go in a plane to measure RPM, Amps, and motor voltage, and store that data for download
to a computer via a serial or parallel connection. Supply the computer software to display a
graph(s) of that data through the whole flight, and do it for less than $200. Yes, I know it
has been done, but the units I've read about are overly expensive for the 'curious',
average modeller to afford. How about it? Can it be done, be accurate, and be
relatively inexpensive? Km"
I think I have found what you are looking for!
Milan Lulic, one of the editors of the German "Modell" magazine has come up with a little circuit (1 1/2" x 1 1/2" x 1/2"), 1/2 oz. which goes in your plane, plugs into a spare receiver channel and measures Volts, Amps, RPM and has one extra input where a height sensor, temperature or even an airspeed sensor can be connected. You control the measurements from a spare channel on our transmitter. Up to 250 data sets are possible. Then when you land the plane, you connect a LCD readout via a 4 wire connection and then you can scroll through all your data. You can also download it into your PC. The thing even measures your mAh consumption during flight, as well as static measurements on the ground.
And now the really good part: the whole thing (as a
