I'm just getting started framing up my On30 layout and plan to use radio control with DCC supplied via Arduino (DCC++).  I currently have three steam type locos, all Bachmann;  2-8-0 outside frame Consolidation, 2-6-0 Mogul and a two truck Shay based on an HO three truck Shay mechanism (Boulder Valley kit).  All three locos have DCC with sound and this is an important feature for me.  I'm hoping to get at least two hours of run time on batteries.
1)  Can someone suggest a good charger for me?  From what I've read I'll be able to use a 400 to 500 mAh battery for two hour run time.
2)  I've been leaning towards the Tam Valley RC system since it's compatible with DCC.  I'm thinking I would be connecting the power supply and Arduino to the transmitter and use a wireless handheld control.  I want the control to have knobs, buttons and switches versus being a cell phone or iPad.  It didn't appear the Tam Valley control would work for my application.  Would other controls work with the Tam Valley system?  Could someone make a suggestion for this?

Tam Valley is a proprietary system. Unless you make your own, e.g. like featured here, you will not have a knob-and-lever control.

Helmet - Thanks for the reply.  I don't want anything connected to the Internet for security reasons.  I guess I'll hafta keep looking.

To use WiFi technology doesn't mean there is connection to the internet. It is always best to understand how the different R/C systems work before making a decision.

Helmut - thank you for your comments.  I obviously have a lot to learn.  I'll keep reading.

Tom,

From what I gather in regards to the former Tam Valley system (also looking at it for future layouts, saves a ton on wiring) there are two modules.  One module is the reciever and it is connected to the decoder.  The other module is the transmitter and that is connected to the command station of the DCC system.  The transmitter will convert the DCC signal into a radio wave and broadcast it through the air, which is picked up by the receivers in the locomotives.  The receiver converts the radio wave back into a DCC signal which is then decoded by the decoder (hence the name).

The system does require additional space for the receiver and the battery pack (plus any control switches, fuses, etc you might want to add.

It sounds to me like a cost effective and much better system than running hundreds of feet of wiring.  You even get to keep all the DCC functions if you want, or use basic decoders.

Oh, and don't forget to look up the new owners of the Tam Valley system.  Tam Valley discontinued, and then sold, their RC system to a new company.  I forget the name but a couple recent threads mention it.

Finally, there's a new kind of throttle coming out called the ProtoThrottle, produced by Iowa Scaled Engineering.  It's a wireless controller with the knobs and buttons, in a simplified format, of a real diesel engine. I believe it will be offered for sale early next year. For an operator throttle, it looks to be perfect.  However, for programming engines and such, you really should have a standard DCC throttle.  Easiest way to start is to buy a beginner's DCC system and hook up an area to test, program, and run locomotives a short distance.

Good luck with the layout Tom, be sure to post progress!

--James

James - I appreciate the info.  I think the name of the new company for the Tam Valley system is called Dead Rail Installs.  I've been going over their website as well as Tam Valley's, CVP, BlueRail, etc.  I'm pretty sure I'm making assumptions based on misunderstandings about how the system works.
I want to use "dead rail" radio control.  I want use Arduino DCC++.  I'm pretty sure the Tam Valley system will work with the DCC++ system.  I think my confusion is about using a hand held wireless controller.  It looks like The Tam Valley transmitter can be added to a wireless throttle.  Maybe this is what I'm looking for.  I'm planning to call Dead Rail Installs tomorrow and see what I can learn there.  I'll get back here with any info I can dig up.

I've looked over the info Deadrailinstalls provide on their website.  What you do is to take the continuous stream of DCC, as provided by a conventional DCC-CS ( any make ), and send it out over the 915MHz band ( 916.49 MHz@2.5mW or 4dBm to be exact, because with the TXM916 ES you can go for 100% duty cycle which is essential for this application ) to all receivers listening there. The receiver( RXM 916 ES, could you imagine?) converts back to a continuos DCC data stream, which is then fed to an H-Bridge to generate a full DCC-square-wave signal. A decoder is jacked up to it in standard fashion. All power needed by the loco must be provided by the receiver module through its H-bridge. The receiver can be fed by battery or constant track power via rectifier and filtering. The decoder uses only the relevant information it is programmed to react upon ( address etc. ). On the CS side, if it is LocoNet compatible you can use any handheld controller ( cable or wireless, but beware - there may be interference because most of the wireless handhelds use the same frequency band ) that works with LN, or if it's Lenz, XpressBus compatible handhelds ( also cable and wireless ). When using wireless handelds, you should better look for ones that operate  at 2.4GHz, saving you from possible interference problems.

Note: Added some technical data for the RF devices used

Tom,
I was exactly in your position 6 mnths ago.
You simply have to read everything in this 'R.C. Control - The Future' thread before you do anything.
 I am running 3 (soon 4) O scale mixed engines on battery power and remote controls a la cheap toys and my grandson is quite enamoured with it and it's extremely affordable - thanks to Woodie, Helmut and Si:Salute:

Here is an interesting device that takes the pulse train (PPM) from an existing 27/75 MHz transmitter and converts it to 900 MHz:
http://www.microflight.com/Online-Catalog/Radio-Systems/Monolith-Buddy-Box-Transmitter

The device may also work to send DCC signals out at 900 MHz.  I have one but have never used it as I switched to 2.4 GHz when that became available.  Maybe one day I will try the Monolith when I have nothing else to do.  Yeah...   ;)
