Re: Triang Wheel Sets

Firstly thanks for the replies. Replacement wheels, whilst ideal, would be difficult since there are few model shops dealing with trains and/or spares here in South Africa. Also the Postal Service is to all intents non-existent even more so with the virus lock-down. I have been ordering electronic i...

Triang Wheel Sets

I am partway through renovating a Triang Diesel Shunter (R152) of early sixties vintage. As usual I put the cart before the horse and installed a DCC chip and got that side working OK. I have now started to try and re-profile the wheels to work on modern track and have hit a problem. I have removed ...

Re: Using vintage hornby locos

Thanks for the feedback regarding case hardening.

We have a club meeting at the end of the month so I will put some feelers out to see if anybody has access to a lathe etc

Re: Using vintage hornby locos

Hi thanks for the reply. Most of your options would be difficult achieve in this part of the world as we seem to a dying breed. Model shops a becoming few and far between. I have just tried running a number of locos over some Roco and other manufacturers points and they seem to jam at the frogs. I t...

Using vintage hornby locos

Most of my locos are from the 60's and have been converted to DCC. I have laid a new layout which incorporates a number of Hornby R8072&3 points. Originally I wired the track (blocks,sensors etc using twin flex but I continued to have conductivity problems especially with the frogs. Having watch...

Re: DIY 4 Function Decoder

Further to my previous reply I have now received the adapter (from China) and have programmed the chip without any problems.

I have also etched the pcb and mounted all components except the PIC and the output IC (hasn't arrived yet).

Many thanks

Re: DIY 4 Function Decoder

I have now located a surface mount to DIP adaptor for $1.31 on Ebay so I have ordered one which, if it works ok, cut out a lot of frustration etc.

Re: DIY 4 Function Decoder

There are a number of ways I can tackle this problem. I think I'll wait until the components arrive so that I can get a better idea what I'm up against. Even my soldering iron will need refining to a needlepoint.

I will come back in couple of weeks when the comps arrive.

Re: DIY 4 Function Decoder

It seems that I am having finger problems again as my last reply is out of sequence. For those interested the POWS web site is:- http://usuaris.tinet.cat/fmco/home_en.htm

Re: DIY 4 Function Decoder

Hi I didn't go to MERG as suggested but instead did what I should have done at the beginning and that was to do a Google search. Many of the search results implied that I should put a suitable connection point on the PCB so that there would be a permanent connection on the board. However since the P...

DIY 4 Function Decoder

Hi I am about to build a 4 function decoder as shown on the POWS site and I have just realised that I can't program the PIC12F629 in my normal programmer since this decoder used surface mount components. I will have to program it in situ ie once it is soldered to the PCB. I have never done this befo...

Re: TCS T1 Decoder Help

What I have done is to make a 4 way function decoder from a Web Page using a Microcontroller (PIC12F629). This gives me 4 led outputs two of which I can use for the front and rear lights and one of the remainder for the interior lights. In fact I could even split the interior lights into 2 strips. I...

Re: TCS T1 Decoder Help

Many Thanks

I thought that was the problem. I'll open up the body a bit further to get to the pcb etc and see what would be needed to separate the interior lights from the running lights.

TCS T1 Decoder Help

I have a Bachmann two car DMU (32-902a) which I purchased a few years ago as DCC Ready. The DMU comes with running lights on each unit plus interior lights. I have fitted a TCS T1 decoder to the power unit and I have also installed another T1 (spare at the moment) into the dummy car. The T1 comes wi...

Re: Locomotive LED's

Hi Steve I'm surprised nobody has come back to you on this. I am a relative newcomer to this subject myself and am still in that learning curve although I have built a DIY DCC system from a circuit shown on the web and this process made me aware of my shortcomings. The question is how good are you h...
