Looks good to me, TwinDad.

I did check the datasheet and apparently there are no issues however you set the inputs. They even need to be the same for turning off the outputs. I don't like the...

Well, the first thing to notice with modern ESU decoders: Get the latest JMRI (production) version. A lot has been done on ESU decoder support between 4.18 and 4.20 and quite another bit between...

I don't know that chip, but I'd assume that too :) as well as some reasonable behaviour if both inputs are active for some reason (floating FET gate).

I understand you are OK with always having...

Yeah well, you got past the frog, so it doesn't really matter where exactly the rails join :)

Nice clean work,

Well, not directly. It's a full-blown DCC command station for ops with Loconet support, 120 locos and an integrated LocoBuffer-clone for connecting a PC. Although the output power is heavily limited...

I spent a little time with a pencil, drill, hobby knife, files and worked some holes into the housings of my Minibox 2 DCC command station:

Just wanted to wish you good luck :)

Go ahead. Especially on design things, I'm "wrong" more often than not ;)

Those two get my vote. Not sure whether I prefer the round or the parallelogram, definitely voting for the wider (higher) green background stripe to the lettering. Though maybe somewhere in between...

Sorry for that :lol: :cool:

Just a quick warning: UK customs are crazily busy with Brexit right now. Sounds crazy, since the rules for shipping to the EU are basically the same as for shipping to (for example) Canada, but all...

That was going to be my first sentence on this :)

There's one big problem in any H-Bridge: If you take a half-bridge (N-FET+P-FET with connected gates and drains, like your Q2/Q4) connected to...

I can't really make it out from the picture: Did it lift because it got longer (or the wood shrunk)? Your note on having to unsolder it sound like that to me.

In that case, you can "just" make a...

Depends on what the stuff connects to. As a rule of thumb:

Stuff that only connects to the track signal (like autoreversers) are compatible with each other (within the scope NDave and TwinDad...

I love them too :) I don't have a proper crimper, but I solder them. Works as well, as long as you don't get any solder running into the contacts themselves. The plastic hood is long enough so the...

Yes, #5 should work. And it doesn't leave you any more exposed to human error than #s 2 and 4 :)

You could even glue some stop piece on the controller or fashion some kind of removable stopper -...

If you can, get it out. Try pushing with a toothpick from the outside, it may be press fit and not glued.

If not, use liquid masking material. I've had good results with Micro Mask Liquid Masking...

I stumbled over some very large import tax free amount for goods delivered to the US and CA. Can't recall how much exactly, but somewhere in the $400 to $800 range, I think. Don't even recall if it...

Depends on how large your layout is... The closer you get your boosters and "power managers" to your power districts the better.

On an HCD or 8 x 4 that doesn't matter. But on an around-the-room,...

They don't always have spare parts in stock, but if they don't, often...

Keep in mind the issue is not really how much current your locos draw but how much current your command station/booster(s)/circuit breaker(s) need to detect a short.

So even if you only draw 200mA...

I've been busy programming a little and documenting a lot for my DIY WiFi throttle controller called wiFred.

The latest 0.6 version is not really documented in there, but the PCBs have reached...

What TwinDad said.

Yes, or if you were running a 500kHz PWM and needed to slow down the rise and fall times of the gate voltage on turning the FET on and off to avoid radio interference in a commercial product. Or if...

I beg to differ: I'd keep R2. It makes sure the FET stays "entirely off" while the Arduino reboots or is flashed or if you accidently turn the pin to an input. If you leave it floating, it may load...
