... don't think powering a relay off that would work. Don't know the proposed method of controlling the switching of the servo but a dpdt switch could control the polarity as well. If you are worried about the servo switching off and the blades losing contact, then you have the blades too stiff. The servo will in fact still be powered, it's just that the control signal stops. If you need to have the servo constantly trying to hold its position with stiff blades and use a system which can do this (optional under MERGs Servo4 I think), you run the risk of burning out the servo motor and fairly rapid failure follows etc. In practice it is usually found (at least in my experience) that there is enough resistance in the servo motors gearing to hold the blades in position. If you want to use a Frog Juicer, I think I'm right in saying that TAM Valley ones can handle 5amps, in fact I seem to recall without checking that they are switchable between systems that are less than 5 amps and those that are ...
... topic: 3116 MERG CBUS system posted: 24 Oct 2017 12:55 from: FraserSmith This topic is to complement the MERG DCC topic and be a place where the CBUS system can be discussed. CBUS has been developed by members of MERG to provide a means to connect control panels with devices detecting occupancy, operating points, signals, water columns, level crossings etc etc via just 2 wires carrying messages and two wires providing a 12Vsupply to power those devices. For a control panel one or more CANPANEL modules can be used. Each module can monitor 64 switches and drive 64 LEDs but only need 4 wires to connect the panel to the rest of the layout. For operating servos to change points you can use a CANMIO-SVO that can drive 8 servos to give realistic switch blade movement and also monitor 8 inputs to detect block occupancy or switch blade position using micro switches on the MERG 3D printed servo mount. Additional micro switches can be used on the servo mount to change the crossing polarity as the switches move so eliminating the need for ...
... suppose I should say that I have no connection with the company! posted: 10 Aug 2015 10:31 from: Howard Les G wrote:...the home DIY printers deposit plastic onto a plate, on ours it is heated glass. This deposition process means that any overhangs are unsupported. Test prints of arch-like components all show a degradation of the under-surface at the top of the arch, amounting to about 30 degrees of arc. For filament deposition printers (such as the Makerbot I use for the MERG kits) the effect of temperature can help overcome this. The two servo mount kits illustrated were printed at different temperatures. The higher temperature makes the filament (PLA in my case) less viscous and so it does not span the gap. 1547_100524_220000000.jpg undefined BTW it would help if the scale/gauge were mentioned in these posts.

... /www.copnor.enta.net/FS/TheBouncer.htm I quite like the idea because I couldn't really get my head around the idea of using a Tortoise or Fulgurex motor for a 4mm ground signal. I've experimented with memory wire and like it but it takes up rather a lot of space. Cause for some more experimentation! posted: 25 Nov 2009 06:10 from: Stephen Freeman As far as I can see from his website, The Bouncer gives you just one bounce. Well if you just want it for turnouts, there is the MERG design, I believe the design is freely available along with the software and firmware. but you also have to have all the kit to flash program the chip. The software to do this is free from Microchip but you have to buy the Programmer (Pickit2 possibly- there are others). To buy the kit for Servo4 though, you need to be a member of MERG but if you have no other need for flashing eeproms then membership is recommended as the chip in the kit comes ready flashed. There are other ...
... topic: 3113 MERG DCC system posted: 21 Oct 2017 23:52 from: Rob Manchester Hi, Prompted by a reply on another Templot thread tonight I would be interested to know any thoughts or owners experiences on the MERG kits for a DCC command station and handset as reviewed in BRM last year. It would make joining MERG worth it to get a full feature system for a very reasonable price. Some of the kits for signal and turnout control sound interesting too. Regards Rob posted: 22 Oct 2017 10:50 from: Charles Orr Hi, I have been a member of MERG for at least the last 10 years, Templot even longer. I have built a full CBUS DCC system, comprising a handset, command station and boosters. I use it to control my still evolving layout. I started many years ago with a ZTC system, changed to Lenz and now CBUS DCC. I'm very happy with the precise, flexible control it provides and would thoroughly recommend it. So for me it's TEMPLOT for track and MERG for control ...

We do have the existing units, is it essential that they be changed? Anyone writing new stuff can clearly use any style they prefer, the only really significant point being that it compiles without errors and works. Changing the subject, did we follow up on my previous comments? What I'm finding very difficult to fathom is how to merge the units together? While you have been making changes to these units, I have also been making changes to some of them. Which means we now have 3 versions of each file: 1. as currently on SourceForge 2. as modified by you 3. as modified by me Which of us does the merging and conflict resolution? What happens if while one or other of us is doing that, the other makes some further changes -- which may or may not be compatible with the results of the merging? ...

... out the smaller details are going to be lost. There are several resampling algorithms available for the sketchboard, but the very highest quality is just too slow to be practical. style="BACKGROUND-COLOR: #f8fcff"Regarding the grating 'blackout', this is an effect known in physics and photography, as 'interference lines or rings', (I forget the correct name, it's something like 'Maurrey interference'), where, as lines or concentric rings get closer together, they interfere with each other and distort or merge together to give a thicker (blacker in our case) look to an image, and the nearer they get (the smaller the reduction in our case) the worse the effect becomes. I have posted 5 screenshot images of the turntable taken a varying degrees of enlargement and reduction to show what the effect looks like to this image as being drawn in Visio.

... the plan so far with platforms in place. 479_060625_340000000.png Of course the track is far too narrow for led's, so revisited the thick centre lines options via Output Mode Options/Detail Mode only this time ticked the option with platforms and track bed edges. I set the line thickness at 50. Went back into Sketchboard and in diagram mode had the plan as shown above, but once I deselected diagram mode the track came up thicker, but the platforms have lost their colour option and both the bay platforms and through platforms have merged into the track centre lines.... 479_060631_570000001.jpg What I'm looking for is the thicker track lines plus clearly defined colours for the platforms.

... topic: 2225 Merging sleeper spacings in multiple plain track templates posted: 27 May 2013 21:48 from: acoake Hi, I have created a track plan using NER 45ft sleeper spacings. So far- so good. However, due to the track layout, I have had to use multiple templates to get the various curves and straight sections that go to make up the plan. Each template starts the NER 45ft sleeper spacings from the beginning again, with the result that there are some very short panels at the end of templates before the next template starts. Is there any way to merge several templates together so that a consistent sleeper spacing for the full length of plain track can be achieved or to force a consistent sleeper spacing over a group of templates? Any suggestions will be gratefully received.

... S7. There is a three-way tandem (they seem to be in fashion at the moment, although I've taken heed of all the advice) I need to finish- its just overlayed right and left hand templates at the moment. When I get everything just right I'll put the V crossings in the right place and play with partial templates to produce the definitive template. However- I cannot get my head around the alteration of checkrail lengths, shortened or lengthened! There are several place where check-rails should seamlessly merge through turnouts and crossovers, but I get hopelessly lost in the various acronyms and options, so that anything I produce is actually by guesswork and accident. Can someone help me though this please? Thanks. Phil PS Surprisingly, shoving timbers is actually quite a restful task.

I've done what you suggested and merged the two sets of templates and they look fine. I'm glad you suggested re working the bay platform lead that should make reversing trains into there a lot easier.

... steeper learning curve than hoped for. The more advanced functions are needed and used by experienced Templot users, including me. I can't take them out just to avoid frightening beginners. No beginner is forced to use them -- I don't really understand what is confusing about simply ignoring what you don't understand until you feel ready to try using it. The difference between the control template and stored templates is what makes it easy to build up complex formations from partial templates. During the development phase of Templot2 I tried an option to merge the two, but the general feedback was that it made matters even more confusing, and some operations impossible. The option is still there if you want to try it -- on the program panel window click the program> click-mode options> make-on-click mode menu item. The top toolbar shows orange when this mode is in force. It is necessary to right-click on a template to display its menu. User inputs such as at Real>Rails>Rail Section Data are very nice ...
