Hey Terrere,
I know you posted these messages a while ago, but in any case, welcome! Always good to see someone else getting into MT.
I'm just getting back into building guns now that I'm on holidays over Christmas, so have been catching up on posts in here.

It's interesting what you discovered about the Rev J PCB on OSHPark. I'll have to put a note on there about the shortcomings you mentioned so that other people don't fall into the same trap.
I've never actually tried building a module with that PCB, I just uploaded it exactly as-is after downloading it from this topic:

I can vouch for the Rev H board. I've built about 8 of them now with no real issues.

One thing I would avoid at all costs though is buying the boards through OSHPark. I personally don't think they sell very good quality boards at all. Almost all the boards I've bought from there over the years have either straight up not worked, or failed within a couple of months.

For my last batch of boards I used . The quality seems excellent to me, very easy to solder, and they are pretty cheap.

Oh and you're assumption about the score collection was correct as well.

I've used the "MT550-02 RevH 1700 16MHz.HEX" firmware for guns, and "MT542-01 FULL.HEX" for score collection, and haven't had an issue.

Hi heningto,
At the moment I think your best bet for DIY Core boards would be Rev H seeing as it is so well documented. I've built some and not had any worries.

If you're interested I've uploaded the PCB design to OSH Park:

I would also really appreciate a parts list for Core Rev J.
I'm currently building Rev H boards myself and haven't had any problems with them, but it would be good to change to the newer version at some point.

I know it was a while ago now but thank you so much for publishing these Jim.

For anyone interested in the Rev H board, I've just uploaded it and shared on OSH Park.

Thanks heaps for the reply Tony.

I'm only getting about 0.02V across pins 3 and 5 on the USB-RS232 cable, so I guess that's the issue.
I was trying to use one of these:

I think I'll grab one of these:
It actually mentions in the description:
"RS-232 data signals; TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, GND."

Do you think that should do the trick?

Hey guys,

Sorry to resurrect an old thread, but I'm having trouble with this same thing at the moment.
I've got my cheap USB-RS232 adapter cable, and I've made up a simple cable just like in the core manual for connecting to the board (using pins 5 and 3 on the DB9 connector), but I'm not able to get the LED to flash when the gun is placed in SFX Recording mode. The sensor LEDs just stay lit.
I'm using the 6.24 Standard firmware, and I've tried on two different PCs, one Win 7, one Win XP. Both times the drivers for the USB-Serial seemed to install and work fine. The COM port is coming up in the sound recorder application, but yeah no luck getting a connection unfortunately.
Anyone have any ideas?

This looks great Jim, when will it be available for sale?

Thanks very much Jim,

That was the problem alright, this IC programming n00b was using the wrong config fuse settings :-p

Also thanks for checking on the shipment, although having thought about it unless you've already sent them it probably isn't worth sending a couple of chips all the way to Australia. Maybe I could just get you to put them in next time I make an order? I don't think this will be too far off, I'm pretty excited about the new gamebox and scoring system.

Thanks Ale, tried that and it didn't make things any better unfortunately.

I programmed the IC myself, but the board was purchased from milestag recently (still waiting on the chips due to a shipping error), so I assume its a 16MHz crystal.

BTW the firmware I'm using is RevH_541-01_16MHZ, and I have sensors connected.

Hey guys,

Just a quick question - will a MT core function with a blank sound chip? i.e. brand new chip inserted in the PCB, no sounds saved to it yet?

Asking as I'm testing a new gun and its performing really strangely so far - The timer doesn't seem to count, reloading takes forever, can't shoot, etc.

Thanks for checking those, and letting me know about pin 6.
The problem turned out to be that I hadn't enabled the option for the PICkit to power the circuit, doh!

Here's the solution for anyone else:

BTW Tony, thanks very much for getting that gun body kit to me so quickly, I received it the other day and it looks great, really looking forward to building it.


MilesTag CORE / PIC18F2525 programming help
« on: December 21, 2013, 03:02:54 AM »

If someone could please give me a hand to get this IC programming thing sorted out, I'd be really grateful.

I've recently purchased a PICkit 3, with a universal adapter board, but I can't get the mplab programmer software to recognise the PIC18F2525.
I suspect its probably the wiring. I went with the wiring that seemed logical to me, based on the PICkit 3 pinout diagram, and the pin diagram for the PIC18F2525, but hey, I've probably got it completely wrong.

The attachments show the pin diagrams for the pickit 3 and the IC.

Here's how I'm currently connecting the chip:

PICkit 3PIC18F2525

Any help would be great, cheers.

MilesTag Micro (uMT) / Re: uMT issues outdoors
« on: May 27, 2013, 02:14:01 AM »
Ah ok, now I get it.

Ok so I'll try to establish what the focal length is on the lenses that I have, use the formula to see how well that matches with the TSAL6100, and if it doesn't look good I'll have to change one or the other until I have a combination that will work well.

Hi Tony,

Thank you very much for your help.
Thanks to your last post, I've been able to improve things quite a bit. I've tested outdoors with focal lengths between about 128mm and 140mm, and I'm getting much better results.
Now I'm trying to work out as close as possible, through using the formula and testing, what my ideal focal length will be in terms of decent range and spread.

If you wouldn't mind checking my logic on this, that would be great.

The mounting of the 50mm lens results in a usable diameter of about 45mm, so using this:

Radius = 45/2 = 22.5
FL x tan(10) = 22.5
FL = 22.5 / tan(10)
FL = 127.6mm

So what do you think, is approx 128mm likely to be the best focal length for my application?
