Andy Y Posted February 16, 2010 Share Posted February 16, 2010 An interesting piece of kit John. I'm assuming then that if the point blades are wired to the frog then there's no need for any switching linked to the point motor - I can see this eliminating the shorts that occur when a point throws but the attached switch fails to act accordingly.

BromsMods Posted February 16, 2010 Author Share Posted February 16, 2010 Exactly Andy. I'm experimenting using it with circuit breakers at the moment - will report back when tests complete. Link to post Share on other sites More sharing options...
BromsMods Posted March 8, 2010 Author Share Posted March 8, 2010 Provided that Frog Juicer is wired OUTSIDE of the circuit breakers it seems to work fine and would appear to be a solution to those in the DCC area who are reporting continual problems with shorts on points.

Sorry to be thick! By "outside" do you mean between booster and CB, or between CB and points? I would assume the latter, otherwise the user will have to adjust CB speed to be a bit leisurely. I see an extra advantage of these items to be the ability to use DCC with live-frog points without motors, which will assist in certain designs of layout where point motors are seen as unprototypical, and either five-fingered, individual lever or lever-frame operation is preferred.

It is also useful for unmotorised sprung or trailing pointwork, and obviously live crossings that would otherwise need a changeover switch on the panel. I can't really see it solving issues that can be overcome in other ways, but it does have the advantage in being a "Fit & Forget" product that saves alot of time.

Ron Ron Ron Posted March 8, 2010 Share Posted March 8, 2010 I'm quite interested in one of these devices. It would significantly simplify the wiring for the station throat that's on my drawing board. Tam Valley have a couple of wiring diagrams on their web site. They show just how easy it is to wire points and crossings using the Hex Frog Juicer. The double crossover just requires four wires ! Here's the link Tam Valley - Hex Frog Juicer ....I see an extra advantage of these items to be the ability to use DCC with live-frog points without motors, which will assist in certain designs of layout where point motors are seen as unprototypical, and either five-fingered, individual lever or lever-frame operation is preferred. Indeed; but you could also use manually operated point motors with built-in switches, such as the Blue Point Manual Turnout Control or the Bullfrog Manual Turnout Control, attached by control rods or wire-in-tube to your chosen lever arrangement. For just a couple or so points/crossovers it might be a cheaper route. . Link to post Share on other sites More sharing options...

I would assume the latter, otherwise the user will have to adjust CB speed to be a bit leisurely. I mean that the supply does NOT go through the CB, otherwise the HFJ will be restricted by the speed of the CB. If the HFJ was to operate via the CB there might well be a conflict. You want the HFJ to switch the power BEFORE the CB cuts power to the circuit. Link to post Share on other sites More sharing options...
RMweb Gold Donw Posted March 24, 2010 RMweb Gold Share Posted March 24, 2010 These also look to be the asnwer to diamond crossings where you would otherwise have to link up to associated points. Donw Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted March 25, 2010 RMweb Gold Share Posted March 25, 2010 I've got to say these sound great and if I were starting Summat Colliery now, with the Powercab then I would be seriously considering them. I problem I can see though is the "hex" bit. I'm sure I'm not the only one with a layout with two boards and a few points on each. To realistically use this device I would have to have one with MORE wires running between both boards - increasing the chances of failures etc at shows. I have just four wires running between the two boards at the moment, two for the DCC bus and two for the 19vDC supply. What would be good would be a series of boards, binary, tertiary, quatro frog juicers so I could have afforded to have a pcb on EACH board as I currently have with the accessory decoders. It is still far more cost effective in this senario to put a cheap microswitch on each point (or use tortoi) and a couple of NCE EB1s to protect against shorts. Not the same operationally, but to be honest, even with a Frog Juicer if you run against an incorrectly set trailing point you will just derail rather than stop due to a short (agreed this senario will be VERY useful to those with unsprung points that are operated by the movement of the loco over them in a reversing loop!) Sorry I'm rambling, but you can tell that I've put a lot of thought into the issue of automating frog switching Link to post Share on other sites More sharing options...
BromsMods Posted June 18, 2010 Author Share Posted June 18, 2010 With our latest stock we've managed to reduce the price to £49 for each Hex Frog Juicer plus £3.50 carriage for each (to a max of £7) - this then covers Special Delivery for multiple purchases, as many customers have come back for more, buying two or three at a time.

Tref67 Posted October 27, 2010 Share Posted October 27, 2010 I presume this will happily deal with anything with a Frog in it? So just as effective on a single slip.. I have heard of stalling causing sound fitted locos to "restart" does that happen with this? Not that I have any sound fitted locos yet, but would rather be aware if it could cuase problems later! Thanks, Tref. Link to post Share on other sites More sharing options...
BromsMods Posted October 27, 2010 Author Share Posted October 27, 2010 Yes, it should do - remember, though, that there are settings in Loksound decoders that prevent a loco going through the complete start-up process if there is an interruption to the sound. In addition, the capacitor that comes with many sound decoders should retain sufficient power to overcome any momentary break in current supply, and the HFJ is so quick that it should eliminate any break in sound. Incidentally, we should be able to retail the HFJ through our web site from January, I'm told, so it will then be available on-line. We are currently out of stock but will have more on Monday 1 November. Edit: Mon 1st Nov - now back in stock Link to post Share on other sites More sharing options...
Tref67 Posted October 27, 2010 Share Posted October 27, 2010 Thanks for that... it may provide a solution and allow me to play trains and test track on my layout before I get point motors installed, which have kind of stalled the project so far... I'll set an alarm for Monday! Tref. Link to post Share on other sites More sharing options...

BromsMods Posted November 1, 2010 Author Share Posted November 1, 2010 how many points/frogs will it work? Or should I go for the single units? (1) 6 - but it doesn't "work" the points, it just acts as a device to eliminate short circuits on the frog. (2) That depends on your requirements............

Tref67 Posted June 24, 2011 Share Posted June 24, 2011 Hmmm... so it would seem from this thread I ordered this in October, and only now am I connecting it up... which leads to a couple of questions: 1. Depspite having only four points and a single slip I appear to have more than 6 frog-wires dangling below the baseboard (just counted 9... how did that happen?)... being of a lazy mind, can I use a "trial and error" approach to see how many of these can be doubled up, or could the potential short cause damage? 2. Can I do any damage checking continuity with a multimeter (I seem to recall I have one wire on the track fed round the wrong way from my initial wiring up, but I can't "see" where it is, so will have to test)? 3. Will damaged be caused if I were to connect up a conventional DC controller (an old H&M Duette) for checking clearances with stock not yet converted to DCC? Thanks to anyone who can provide answers, Tref. Link to post Share on other sites More sharing options...
BromsMods Posted June 28, 2011 Author Share Posted June 28, 2011 Any plans to stock the Mono version John? We have had both mono and dual versions as well as the hex and servo on our stock list for a few months now, though we have sold out at the moment, but expect more in a week or so.

BromsMods Posted August 4, 2011 Author Share Posted August 4, 2011 Received even further stocks today of the Hex Frog Juicer, with a small stock of the variant designed just to work with the NCE PowerCab. Have managed to reduce the price a little as well. Also have a small stock of the 5A booster from Tam Valley. Link to post Share on other sites More sharing options...
