Hi DMNC,

Is there a way of creating an icon that calls Terminal and then TG-Timer? It would be nice just to click the icon and away we go!

Thanks

Snake
Hi!

Just open the script editor and type the following code:

tell application "Terminal"
do script "tg-timer"
end tell
Save as app, and there you go! You can add an icon later on through the finder.

Anyway, just downloaded this app, I haven't used it a lot but it seems to be working pretty well with a cheap phone handsfree kit.
It's struggling to pick up some diver's noise but it seems to be working great on other watches.
I'll try tomorrow with a piezo mic but so far so good.

Keep up the good work!

I just wanted to say thank you for this awesome software. I use it extensively to monitor my watches.
Keep up with the good work and thank you for making this open source.

fyi folks:

SECOND UPDATE: i'd like to thank WUS member 'Apollo83' for his post in this thread, which shows the use of a Logitech webcam as a sound input device - after going through this thread twice i had a 'smack the forehead' moment when i realized i had one of these in a drawer - works under OS X and Raspbian (Debian GNU/Linux) - and now i have a much cleaner input source than the cheap lapel mic i had been futzing with - so thank you, sir!

UPDATE: tg-timer builds and runs just fine under the Raspberry Pi's Raspbian Debian ARM distro... i have it installed on an RPi3 with a CMedia USB mic input and 3.5" TFT LCD (client is run via a VNC screen-sharing session due to resolution constraints) - a little timing device for less than US$60!

very nice!

ORIGINAL:

- the Win7+ .msi version of tg installs and runs just fine under CrossOver on OS X 10.10.5....

(now off to find a decent mic)

+1 to the developer - very good work

A mic from a timegrapher wouldn't work with this? Just curious while trying to read what everyone has used so far.

I don't see why it wouldn't. I have two old Vibrograf mics and one has the original Rochelle salt microphone element and one modified with a modern piezo disc. The original one is much more sensitive, but they both work.

What's kinda plug do you have on them? I have a watchmaster mic that has a 1/4 inch male plug, was thinking of getting a modern one and converting the plug into headphone plug to work with this.

The original Vibrograf plugs are proprietary, and they're both different. I actually had to make a suitable plug from scratch to fit my old B100.


For the TG, I just changed one of the cables to a standard shielded microphone cable and a ¼" mono plug connector, which then plugs into my Apogee Duet interface. The type of plug you need of course depends on what you want to plug your microphone into. Mine is an ideal scenario, since I have two separate mono 1/4" instrument inputs in my audio interface.

If your microphone has a standard 1/4" plug, all you really need is a 1/4" to 3.5mm headphone adapter to fit most sound cards.

Could you take some photos and share them?

OK, so here's my modified cable for the Vibrograf mic. The nice thing about these mics is that you can just unscrew the whole cable and swap it to another similar mic. Anyway, this is the end result:

1.jpg

This is what goes inside the mic. The springy part is just an electrical connector and the spring allows it to bend as you change the position of the clamp. The knurled part is the negative terminal, which is connected to the shielding braid of the cable. In my case, the cable is two pole, and the white lead is not connected to anything. The red lead is connected to the positive terminal, which is the springy bit.
2.jpg

This is the other end of the cable. The red lead (positive) is connected to the center pin and the shielding braid (negative) is connected to the other terminal, which is basically the whole larger metal portion of the plug.

3.jpg

And finally, if your mic already happens to have a 1/4" plug, you could just use one of these headphone adapters if your sound card/interface only has 3.5mm input jacks. You don't need to worry about the adapter being stereo. You're simply using just one of the two channels and the other one is shorted to ground.

Perfect, exactly what I had in mind. Vary much appreciated Aku Ankka, I dont think that this has been posted on this page yet so maybe people can get an idea. Awesome

Not a problem. It's a very simple mod and even if one doesn't have much experience with electronics, it's still very much doable on a very limited budget.

Now that I've been playing around with the software a bit, I thought I'd throw a few development suggestions out there:


-Average rate calculation over a period of time, say 1, 5 and 10 minutes for example. This is what the Witschi software does, and it is extremely handy. Ideally you should let the watch stabilize for something like 30 seconds to a minute and only then the software starts measuring. While the Witschi software does this automatically, TG could just have a button that you could click to start the selected measuring period. Once you have measured in 'all' six positions, you can easily read the results and draw your conclusions from them.

-Possibility to print out the results would be nice.

Was gonna say printing would be cool.

Hi my friends!

Unfortunately I had very little time to play with tg lately... I would just say thanks to all of you for your feedback.

@linux.author: I'm happy to learn that tg works on ARM!

@Aku Ankka, nauz: Long term averaging and printing are definitely on the to-do list!

Just to answer my own question and to bring up this thread - this setup works just fine. It doesn't need a preamp and that piezo mic seems to be less prone to ambient noise than a regular iPhone headset.

tg-pickup-mic.jpg

1. Piezo Clip On Microphone Pickup for Acoustic Guitar (~$4)
2. Mono 1/4" female to 1/8" male adapter (~$1)
3. 3.5mm Male TRRS to 2 Female TRS Audio Connector TRRS Y Splitter Cable Adapter (~$2)
4. Vintage MacBook Pro (already owned).

The vital part is that TRRS adapter as you can't just plug your mono mic (TS) into the headphones jack, it won't work.

Also there's a neat little software called LineIn (free) that allows you to hear what TG hears, just plug your headphones into the second TRRS adapter jack.
