I bought a wire rack from walmart and put the PiPlanter back inside my house. Hopefully the plants will live longer than they did last year so while I’m at college I can continue to develop on this model. Images below.

PiPlanter 2 | Solving Broken Pipe Errors [Errno 32] in Tweepy
If I haven’t mentioned it already, https://twitter.com/piplanter_bot IS the new twitter account for PiPlanter. Like last time, I’m using the tweepy library for python to handle all things twitter for the project. What I’m NOT using this time is Flickr. From a design point of view, it wasn’t worth it. It was too complicated and had too many things that could go wrong for me to continue using it. Twitter is more than capable of hosting images, and tweepy has a very simple method of passing these images to twitter. Recently I moved the whole setup indoors and mounted it all onto a shelf seen here and it came with a set of strange problems.
Long story short, what I think happened was that since I moved them to a different location, the complexity of the images increased, causing an increase in the size of the images themselves. A broken pipe error implies that the entirety of the package sent to twitter wasn’t sent, causing the tweet not to go through. I first started to suspect this problem after seeing this:
The graphs were going through just fine, but images were seeming to have a hard time. You can’t tell from this photo, but those tweets are hours apart as opposed to the 20 minutes they are supposed to be. Once I started having this problem, I bit the bullet and integrated logging into my project which produced this log:

Hours and hours of failed tweets due to “[Errno 32] Broken pipe”. I tried a lot of things, I figured out that it was the size of the images after seeing this:
Photos that were simple in nature had no problem being sent. After scaling the image size down, I’ve had absolutely no problem sending tweets.
If you are tweeting images with tweepy in python and getting intermediate Broken pipe errors, decrease the size of your image.
Thanks for reading.
PiPlanter 2 | Progress Update
I’m almost done with a very stable version of the Python code running the PiPlanter. There are many specific differences between this version of the python code and the version I wrote and implemented last summer, but the main one is that I tried to write functions for pretty much every task I wanted to do, and made each routine much more modular instead of one long line after line block to do each day. This took significantly longer to do (thus the lack of updates, sorry) but is much more expandable going forward. Below is the new version of the code, but by no means am I an expert programmer. The following code seems to work very well for what I want it to do.

Note the distinct lack of comments. I will put out a much more polished version of the code when it’s done. Before I move onto things like a web UI etc, I would like to do a few more things with this standalone version. The above version renders videos into time lapses, I would like to be able to upload those videos somewhere, hopefully youtube. I would also like to be able to email the log file to the user daily, which should be easier than uploading videos to youtube.
The script that renders the MySQL data into a graph is the following, it on the other hand has not changed much at all since last year and is still the best method to render graphs like I want to:

I’ll do a much more thorough post when the project is further along. For those playing along at home, you can see that I’ve totally re-written the code for this new version. So far, it has much less functionality but much more stability and flexibility.

Smart Speaker | Modifications and Repair of Lepai LP-A6FM/USB
When trying to charge a cellphone via the USB port on the amplifier, I blew a power resistor and the 5v regulator on the amp. The following images show the repair process:

Here’s a video:
Not much further explanation needed for this post. The design process for delivering power to all components of the system is complete. The topology is pretty simple:
12v Battery -> switch on positive rail -> 5v Switching Regulator & 12v rail -> Amp & 5v Linear Regulator -> Arduino
If you have any questions, please let me know.
Smart Speaker | Full Working Prototype
Here is a video of the whole thing working:
The whole system works! If you look at this post, which basically shows the whole thing can be battery powered as well. The following photos show the way the cable is run out the back of the housing. Both sets of the 3 wires are tied together and then to the output of the digital pot:
Contrary to what I thought, the 10k ohm digital pot can change the volume just fine! To be safe though, I ordered an SPI digital Pot that can do 50k ohm resistance.

#define numOfRegisterPins number_of_74hc595s * 8
boolean registers[numOfRegisterPins];

Once all sample have been made, each value is compared to a like value. If every && evaluates to true, this means whatever object above the sensor has been there for the "cycle_delay" * the number of comparisions made.
It will confirm that the user wants their hand the be there and it was not acciential.
Think of the following loop as the ambient mode, the user can't adjust the volume from here, but they can enter the mode where they can adjust the volume.
It has much less precision by design.

The only difference between this one and the last version I posted was the height of the check value. I made it further away from the sensor.
Before the code is “finished” I would like to add a few things. The first being an averaging loop in the raw input ; instead of just using variations of map(analogRead(IR_rangefinder),20,600,0,9); each time, I’d like to maybe write my own function that is more general for assigning comparison. The downside to this however is that it may slow things down and the top priority with this project is keeping it fast and accurate.
Smart Speaker | Amp Teardown and Potentiometer Problem
Here are images of the teardown:
A couple of things to note: I over heated the pads when removing the gain pot and lifted a trace by accident. Instead of soldering directly into the lug hole, I just tied directly to the resistor that is in series with the pot signal.
I also am also not going to be able to use the digital pot I have been working with so far. Note the image that shows the pot with a resistance of 50k, and the one I’ve been working with is 10k.
I’m going to order a pair of these, and many of these to try and solve the bluetooth static problem.
Smart Speaker | Power System Proof Of Concept
Here’s a video:
This is very simple. Basically this whole thing will work like:
12v Battery -> Amp (5v Regulator) -> Arduino & Bluetooth & Cellphone Charger
I may have to add a separate linear regulator in order to get less noise on the bluetooth as seen in the video.
