Questions / Re: Need immediate with battery case!!
« on: August 12, 2018, 02:33:05 PM »
Hi Steve, very sad you have an overheating battery issue. In my personal research I have found that the issue happens when the battery box is inserted with the batteries 'up' which risks the batteries touching the electronics.

Honestly this didn't crop up with the first run off Kickstarter sprouts and I sadly can't comment on the new units as I refuse to work with data garden any longer. At the current price point, I suggest you treat this as a manufacturing fault and send it back to the dudes. I don't know the best conact email for them, please review your purchase emails. 

I do much of the support on the forum, along with our beatified amazing biodata sonification explorers.  I'll provide anything i can give, and battery boxes are cheap (shipping sadly it's not).

My primary repair suggestion is to trim the wires find a decent gauge of wire any color and solder it to replace the melted segments Use shrink wrap tubing to cover the joins. And then connect a 2 pin header in order to mate with the main power jack. I think soldering is fun, but I understand not everybody has the tools or the excitement!  or I'd be happy to send you a battery box with a header soldered on, and you just need to make sure that the batteries are facing down when you put it into the enclosure.

If you are in Philly, I'd be happy to help in person. Look around and email me directly.

Best of luck, sorry for your trouble.

and stay tuned, I am working on a new version with another group which will provide some significant enhancement, greatly improve support, and perhaps intruding some Wireless, multiple device, and modular connectivity. Get excited.


Questions / Re: MIDI Sprout Tools looks....odd

oh yes as you well know my friend links do change. I changed my entire structure for my website, so anything that's not sitting in my GitHub probably isn't going to link back. Based on your note I'll try to upload to my GitHub this weekend for the mini Sprout tools. Here try this link electricityforprogress.com/DataGarden/pd/

Development / Re: EMG for midisprout?

ure, the 555 timer is set up as a galvanic conductance monitor. Simply replace the galvanic circuit with something that actually can do your egm measurements, put that signal to the 328p,
 and rewrite the software to translate those signals into something meaningful, and then algorithmically process those changes and signals to trigger notes. It is actually would be a completely different system, but you can build and code it on your own.

While midi is magical, you have to learn about specific programs in order to make music. Nicola is an amazing example of someone who is able to use Hardware synthesis and software synthesis at the same time.

I realize that musical instrument digital interface is the hardest part of this system for people. But making electronic music is extremely challenging. Making music with plants is actually quite easy, all you need is a biodata sonification interface.

Yes the device was in for all the hours of the experiment/test.

You can easily modify the code and turn the lights off, just look in the variables declared and set the noteLEDs = 0; which will defeat the main light show (not boot up light show tho).

there is one very large Hazard associated with leaving your Sprout on for multiple days. If you use very low Quality Batteries, I'm talking an Amazon or off-brand or anything that doesn't have a copper top or some green text of the side like aniloops. The batteries will leak after a long drain, just like any device and their batteries. think of the Sprout as a flashlight, it is in no way different than any other electronic device, and you shouldn't think it's special electronically or based on its battery usage, there is no difference in its battery consumption whether your computer is turned on or not.. But you should be able to run on basic power for four to seven days without any trouble.

If you really excited you can easily attach a regulator in a solar panel and a couple charging caps which can keep the unit running indefinitely.

Questions / Re: Question about midi data
« on: July 01, 2018, 08:24:20 AM »
The MIDI data consists of simple notes, most pianos have a max of 88 key, 66 keys, 42 keys, or even tiny one octave keyboards.  The biodata readings are much more nuanced and I have attempted to maximize the sensitivity and resolution of the biodata sonification system by allowing notes to 'loop back' once the highest or lowest note is played.   

If you hear notes jumping from very high to very low, that means that your plant is at the edge of one of these activity areas and the note mapping is jumping to the next loop back point. 

In the image you provided (thanks nicola for posting the linked image) you can see the notes cascading down, down down and down.... this trend is showing a steady increase in 'activity' and conductivity fluctuations.  Yes this is typical for sprout usage and the data is simply wrapping.

Insights .... well that's really up to the user whether a biologist, botanist, philosopher, or florist.  As an engineer, i simply provide the tools, it is up to you and your research to find meaning.

Questions / Re: Using Sprout without IAC Bus?
« on: July 01, 2018, 08:17:22 AM »
What are you using as a USB to MIDI interface? 

You only need to select your USB MIDI device in the visuals program.  The IAC midi bus is a built in router in OSx which is totally not needed if you are doing the direct USB connection.

1. Plug you MIDI/USB device into the computer (don't matter if the Sprout is attached or not)
2. Open sNoize MIDI Monitor and check to ensure the USB/MIDI device shows up
3. open your visualizer program and choose the MIDI/USB device

Kit Instructions / Re: MIDIsprout Kit Build Discussion

The jack for the trodes should not be connected to ground. The tip goes to the threshold/trigger on the 555 chip, the other goes to discharge with a 100k pull up resistor.

If you are building this on a breadboard, I suggest building just the 555 timer block and get that red led flashing based on touching trodes. Then connect the 555 output to the 328p/Arduino.

Questions / Re: Setup and Usage of MIDI Sprout
« on: June 14, 2018, 09:04:48 AM »
I suggest that you use a Midi Monitor (I use the snoize app), and you can ensure that the MIDI device appears on your system and that the MIDI data is flowing.  Once you can see that the device is connected and the midi is flowing, then you can try use the MIDI data in an audio program.

Hello severin. I always have kits available on my electricity for progress store https://squareup.com/store/electricityforprogress

Also the instructable is very old and you should follow the instructions on my GitHub https://github.com/electricityforprogress

You can use an Arduino Uno (with the 328p chip), upload the code, and pop the chip off the Uno and into the sprout circuit board. Otherwise use ICSP to program a bare 328p using an Arduino as ISP setup.

You can use the jack you have, just need to connect the two unswitched pins on the jack to the top two pads on the circuit board.

Look in my git and you can see the uno/breadboard project example if you want to see how using an Uno and simple breadboard works.


Yes any iOS to MIDI adapter should work.  If you can see the iconnect in a synth app on your device, then you just need to connect the Sprout to the MIDI 'Input' of the iConnect and you should see MIDI on channel 1

Questions / Re: Help with midisprout and snoize on Mac

The Sprout is the same as any general midi device, if you can see the device in Midi monitor and you are not getting any data then perhaps you have the wrong jack plugged in to the sprout. What midi USB device are you using?

Development / Re: Future versions of MIDI sprout

Hello good pelgrim, thank you for all of your support, questions, and feedback!

For 2, the sweet spot changes over time. It all depends on what the plant is 'doing' at any given moment. But I agree that software could be a good solution here, perhaps I could include an auto ranging mode.

 power and a rechargable battery at a very simple mod, just hit adafruit and get a battery and charger with 5v out and micro USB input. The main reason not to use USB in rechargeable batteries on the product, is shipping since batteries are dangerous.

Uploading code through USB, yeah that would be easy, but I have included the icsp header and it should be easy enough to use a programmer or an Arduino board to flash code on to the chip.

Above all, the midi Sprout is a simple work. It was never intended to do everything for everyone, and while data Garden continues to produce my open source design, I don't think they have any interest in innovating the process, hence why I left working with them. The whole point of Kickstarter is to invest, not travel.

I already have Wi-Fi and Bluetooth versions which are available directly through me for anyone who's interested. I also have multiple plant interfaces if you're trying to use more than one plant in any given time, and those are available direct from me as one-off experimental units.

Questions / Re: Info about MIDI Sprout translation
« on: May 08, 2018, 01:05:59 PM »
By default the Sprout puts out notes in a 12 chromatic scale. Many if not most users use some other scaling algorithm either in software or even programmed into the sprout, in order to get the lullaby sounds that you tend to hear.

Notes are sounded only when a change in electrical conductivity is sensed in the plant, the note that is produced is proportional to the difference in conductivity between a Baseline and the measured change event.

As conductivity increases the note will go down in Pitch. Since there are only 49, 66, or 88 notes on a piano keyboard I allow the notes to ' wrap-around ' from the highest to the lowest note. This allows very fine changes in conductivity to be expressed using just a few musical notes. This can be seen when the Sprout oscillates very quickly between a very high and a very low note, showing that it's just at the edge of one of those regions.

There are effectively no plant pulses, rather the constant changing electrical conductivity of the plant is measured many thousands of times per second and changes in that conductivity are detected. I wouldn't say that the plant is putting anything out, it's more like we're listening in.

Questions / Re: Using Ios app with a presonus itwo?
« on: May 07, 2018, 12:55:35 PM »
Many midi USB devices will work with iOS, the app and the sprout are standard midi compliant devices. Basically, I suggest searching if your midi adapter works with iOS and everything else will fall into place.
