Re: DIYish DCC Booster Module

That's why I said "effectively" limits. Obviously with Pulse Width Modulation the full voltage is applied during each pulse, but the lower the throttle setting, the shorter the duration and thus PWM generates an effective voltage based on the cycle. For a slower speed, say 20%, the motor has track v...

Re: DIYish DCC Booster Module

No, there is no voltage adjustment. The output voltage is a function of the input voltage. Of course, given that there is no standard to set it to, not being able to adjust the output voltage seems like a non problem to me. I was concerned about a voltage differential between the DCS100 Command Stat...

DIYish DCC Booster Module

Like a lot of members here, I seem to have extra time at the house these days. Luckily I can do a lot of work from home, so the paychecks are still rolling in on time. Since I finally "finished" the wiring in the smaller of the two train rooms, it was time to start planning how to get the DCC setup ...

Re: New KADEE #705 Couplers

I picked up some 705s to put on a few of my GC boxcars and got a bit of a surprise. The 705s use a 00-90 screw and the GC boxcars are setup for 714s which use a 0-80 screw. Luckily I was able to gently ream out the hole in the 705s with a #52 bit and use the 0-80 screw without impeding the operation...

Re: Using a Raspberry Pi with JMRI on the layout

Terry (et al), I was using my laptop to run JMRI and program my decoders. I thought it was OK, but I didn't like using my laptop because that meant moving it back and forth to my test track. I know laptops are portable, but it was inconvenient and I'm lazy. I'm a Computer Scientist by profession and...

Re: Using a Raspberry Pi with JMRI on the layout

After some busy work stuff, I started back on my RPi. I managed to get CentOS 7 running on the SD Card, but it is pretty slow. CentOS is a huge memory hog as well, so I've been scaling back all the worthless processes that it loads/starts. I now have a working version of CentOS, but the default conf...

Re: Using a Raspberry Pi with JMRI on the layout

Thanks Terry. I checked it out and downloaded an image to burn. If I can get CentOS running on the SD card, then I'll move on to trying a hard disk.

Re: Using a Raspberry Pi with JMRI on the layout

So, I got Raspbian installed on the SD Card for the RPi and booted it up. Bleah! As a RHEL user, I'm really hating Raspbian and the lame window manager. Installed the JMRI software and after some wrangling I got it working. Even though I have a SPROG DCC which is capable of running a small layout, m...

Re: Using a Raspberry Pi with JMRI on the layout

Glad to see I'm not the only one. I'll post my progress as I wrestle with it.

First up, get the RPi to boot up!
