My
product is a HVAC filter monitor which you can read more about on our
website (www.airflow1.com). The CFM-GM Clogged Filter Monitor has an
option to connect directly to the breakout board for Twine, you then set
rules to send yourself a text message when the switch closes to check
your air filter.

I've had this running now for over a year and it works great!

Sorry
for informing everyone about it here and on other discussion channels
but hope you take the time to at least see what else the Twine can do!]]> 2 years in from KS & over a year since unit in hand - Promised analog ever coming to breakout board? http://minervakestner.com/discussion/511/2-years-in-from-ks-over-a-year-since-unit-in-hand-promised-analog-ever-coming-to-breakout-board Tue, 31 Dec 2013 13:03:09 +0000 Hardware developers Sean McPherson 511@/discussions
From the original KS: "breakout board --- provides analog or digital input, power and ground
(allows you to easily wire up other sensors that you think up — no
soldering required!)"

From the store website for over a year: "Connect the Twine breakout board to your Twine's external sensor port
and instantly get the ability to measure anything with your own digital
input (analog coming soon)."

Really, this was *the* biggest reason I bought the twine. Everything else I can do thru existing arduinos and such, but I KS'd this because the analog functionality was going to make it useful. As it is, it's been floating around my house for a year as I try to find anything serious to use it for to recoup my costs.

I know so far the external sensors can be only on/off (which is a shame) but i'm wondering is there a way to externalize the existing internal temperature sensor or ultimately add a new one by hacking directly the board.

the place i wan't to use my twine is not covered by WiFi so i need an extension!

thanks

From the comments on the Facebook post, it's currently only on/off... but how many on/offs are there to the shield interface? If there are two "touch capacitive buttons" and a whole bunch of GPIO pins, it seems reasonable to send more complex signals using multiple GPIO pins. Is this possible? Can I say

If pins 5, 3, 2 and 1 are high,

Then send a message "The number is 23"

If so, how about a cable or clip on device that would connect a standard 9volt battery direct to the mini USB slot?. Cable would work, but a holder that a 9volt battery is inserted into, with a mini male plug would work also.

]]> No support for multiple sensors even with splitter http://minervakestner.com/discussion/325/no-support-for-multiple-sensors-even-with-splitter Thu, 24 Jan 2013 14:39:18 +0000 Hardware developers Gustaf Rosell 325@/discussions

I connected the moisture sensor first (which was correctly identified). Nothing happened when I later added the breakout board. When I closed the circuit on the breakout board, the moisture sensor became "wet", and the rule for that sensor was applied (they are all basically just 0/1 contacts anyway).

Everything was exactly the same if I did in the reverse order, with the exception that it was presented as the breakout board.

Can we hope for support for this in the future? Should work, since it is basically just 1-wire IDs.

R6 is the offending resistor, it's an "0603" size. It's 75ohm originally, I replaced mine with a 560ohm "0805" because I had one handy and it still fit over the pads. However you could easily go to 1Kohm and it'll be plenty bright for most situations (maybe not in direct sunlight though.

This mod will also reduce the current draw of the device, although only by a small amount, every bit helps!

A bit of red electrical tape over the LED and now I have a red(ish) LED instead of white, easier to see. Use any colour tape you wish though. ]]> BugTwine: A (super) simple Twine hanger. http://minervakestner.com/discussion/222/bugtwine-a-super-simple-twine-hanger Fri, 14 Dec 2012 11:37:47 +0000 Hardware developers Andreas Suter 222@/discussions
If this is in the wrong section, please let me know and I'll move it.
This is a thread based on the discussion here: http://community.supermechanical.com/index.php?p=/discussion/45/mounting-options-or-insulation.

Using a twist tie I found, I threaded it through the center two holes towards the top of the Twine. This gives me a new mounting point that I can use to hang it with. Thinking about it a bit more, I decided on a twist tie over a paper clip because the tie is a bit more insulated, possibly helping to avoid interactions with the internals. This hanger could be molded into/glued to a magnetic plate, giving more options than the single hole. You could also hang this on a curtain rod, etc.

This "mod" required no modification of the Twine itself. There was enough space inside to thread the tie without issue.

To remove the white case: remove the batteries, and spread the two white clips with your pointer fingers while pushing with your thumbs on the floor plate of the battery compartment. It's pretty easy, but I'm happy to post photos if requested. You might be able to thread the twist tie through without separating the board and white case, but it's easy enough to remove that you'd probably save time by removing it.

I can't figure out how to post photos directly into this post, so for now I'll link to the Google+ album I made: https://plus.google.com/photos/111943890093334087737/albums/5821836919943336097.

Let me know if you have any questions! Thanks!

Is there a Schematic available for Twine? I'd like to save time by using your source documentation rather than do a tear down and create my own document.

Having this info will help me understand the fundamental capabilities of the design and allow me to think of experiments where this will be useful and potentially tweak some of the settings so I can make my experiments more intricate.

Thank you!

I'm trying to determine the feasibility of building my own external sensors. This thread gives the pinouts of the 3.5mm jack:
http://community.supermechanical.com/index.php?p=/discussion/19/3-5mm-jack-pinout

Sleeve 1 gives the ID of the external sensor. I imagine that it is just a resistor value. If you have a multimeter and a sensor could you please measure and post your findings here?

The ID is probably measured against 3.3V (tip) or GND (ring 1) as shown in this diagram: goo.gl/IOPcv

Curious to see that the status for the breakout is either open or closed - is it a pure digital input, then? Or is there firmware coming that could make it an analog input?
