Bike generator for 18650 battery packs – Part 1

Part 2 of the Bike generator for the 18650 battery packs. In this one we build the mounting frame for the treadmill motor, 3dprint an axle connecting sleeve and do some tests with the multimeter to see what kind of voltage we can!. Getting closer to starting to record power generation data to the home automation system!

 

 

Bike generator for 18650 battery packs – Part 1

Welcome to part 1 of the bike generator build.

This build will add a pedal powered bike generator to help charge my 18650 battery packs. This will be in additional to the small solar panel currently in use.

The charge controller and statistics will be build on an arduino controller and tied in to my openhab home automation system for tracking and graphing.

The controller will connect wirelessly using mysensors and an nrf24l01 radio.

 

Good Vibes!!!

So… I have a “friend” that asked if I could help with something.

 

She had something called an OhMiBod.  It’s a …. um… it’s a vibrator.

HAHAHAHA

Super mature.  Anyway.  She has this thing called an OhMiBod Club Vibe.  It’s supposed to vibrate to your music  Looks like this.

HAHAHAHAHAHA

Pervert

Dude really?  ANYWAY!

So apparently she prefers to crank her music from her phone to said vibe.  But apparently this thing is when you crank the volume, the primary function of this thing (vibrating to the music) all but disappears and it’s just “on.”  So I was asked to fix it.

I bet you fixed it.  Haha

Don’t you have somewhere to be?

So.  I decided to see if I could knock back the levels on the audio.  I remembered a tutorial I saw once on how to make an attenuator for video to create a safety track on one of the channels.

Really?  Safety Dance?

So I built out a quick little voltage divider.  Started with a 150 ohm and a 1k ohm.  It helped but it got better once I went down to a 150 ohm and a 220 ohm.

Hehe

*sigh*

So I tested everything out using the breadboard and alligator clips.

Nipple clips..

DUDE!

So now it’s time to tighten everything up

….

NO!  Before this guy completely implodes here.

I took a dead marker out of the craft bin and cut it apart.  Put a piece on each side of the attenuator and soldered it up and have a male and a female 3.5mm jack on each side.

Shut it…

 

 

 

 

 

 

 

 

 

 

 

Once it was all soldered up, I hot glued the pieces together and wrapped some tape around the one end to give the shrink wrap something to hold on to.

 

 

 

 

 

 

 

 

Now lets throw some shrink tube on it and make it nice and neat.

So I gave it to her and from what I “hear” it’s getting the job done.

And I’m the perv… 

So in all seriousness.  This was actually interesting.  I have never hacked part of someone’s sex life before but this was interesting.  Not my normal stuff, but hey, glad I could help.

You lended a helping hand..

I’m done.

PS.  Is a hackgasm a thing?

Progress on the green sprinkler system project!

I have made some progress on the green sprinkler system project.   I even shot some video recently!!!

 

Here is some testing of the water quality…. WHO PEED IN MY BARREL!!

 

Now for the big update!!! Built a battery from recycled 18650 laptop cells.  Hooked it to my pump.  Drained my rain barrel!!  Then charged the battery back up via solar!!!

Man I am feeling kind of green!

Like this guy?

Oh and I am the one that peed in your barrel

Oh %^&* you’re back too huh.

You do realize I am you, you are me right?

Man I had a long night last night.  Don’t do that deep %^&* on me.

Ok Ok.  Check out his (my video)

Rain Barrel Growth Check!

My last barrel was the white kind and it did not do well at keeping light out so there was a swamp monster in it when I checked it.  Glad I wasn’t using it for anything, that water was gross.

 

I switched over to these blue barrel’s in hopes it would be better.

Got a cool endoscope camera from amazon

Amazon

With this camera I figured…. where can i put this….

STOP THAT!!!!

 

 

 

 

Check out my youtube channel for other project videos!!

NO!!! I want to print more!!!! or Offloading octoprint timelapse videos

octo

I use octoprint to manage my printer.  When I can, I batch print.  I will literally print things back to back. But I also love the timelapse and we have all seen it….warning

 

But I have more robot stuff to print!!!!

Settle down there smart guy.

Nobody asked you!

Ok, interruptions aside.  Running octoprint on an original pi is a little slow.

Did you say apple pi?

captain-picard-facepalmI don’t like this guy.

I said ORIGINAL pi.  Yes, old school slow.

So what happens if you try to print again while it’s rending a timelapse… well, you get a lot of stalls on the print, meaning the head sits over the print causing some unnecessary melting.

So how do you fix it if you are so smart?

Well, you would offload it.  I have a linux box that handles all sorts of random tasks.  It could do it.

So here is how I offload it.

  1.  setup an NFS share to a nas/other server
     192.168.X.XX:/mnt/vol/dataset1 /home/pi/fs nfs nouser,atime,auto,rw,dev,exec,suid 0   0 
  2. Configure octoprint to store the timelapse pics on this NFS share.paths
  3. All that is doing is changing the location of the timelapse, not offloading jerk.
    I KNOW!!!  I’m not done!
    Sorry
    So now we need to setup the exact same share on the other linux box.  If I had thought about it early on I would have changed the path on the pi to be something like /media/share/ instead of /home/pi/fs
    So we put the same path on the other linux box.
    (see 2.)
  4. Now the fun stuff.
    Finally!
    I created a small shell script on the PI.

    #!/bin/bash
    ssh root@192.168.X.X "ffmpeg $@"
    if [ $? -eq 0 ]
    then
    # everything was good
    exit 0
    else
    exit 1
    fi
    
  5. Set up your pi to be able to login with no password (using keys instead) so that the ssh connection will not hold anything up.
  6. Configure octoprint to use this new script as your ffmpeg path.
    2016-11-07-19_03_42-octoprint

So let me walk you though it.

Good idea.

Are you being nice all of the sudden?

No.

Anyway.  So octoprint is now setup to store your timelapse images on the network somewhere.  Linux box is setup to have the exact same path.  When your print is done octoprint executes the timelapse.sh script thinking that is ffmpeg.  So it runs it waiting for it to exit with a success or failure.  So in the script, we ssh to the linux box, tell it to run the ffmpeg with the $@ which means everything octoprint wanted to pass to ffmpeg locally we are passing to the remote ffmpeg.  The other box does all the heavy lifting and returns an exit code, we pass that exit code back to octoprint.  It’s none the wiser.

The cpu is next to nothing because we are just waiting for the ssh command to finish.  So I have started additional prints with minimal issues.

I have noticed that if you keep your filenames short and sweet it helps.

Is this a great solution or what?

No.  Buy a better pie.

Don’t you mean a “pi?”  Haha.  Jerk.

Time lapse in new printer enclosure

surprised-rainbow-faceSo awhile back I came across an instructables article regarding using some ikea lack tables to make a 3dprinter enclosure…..

I love ikea….

So this was the project.  http://www.instructables.com/id/3d-Printer-Enclosure-from-Upcycled-Furniture/

I went to ikea.  Got 2 lack tables and put them together…. I want my printer higher up.  ELEVATE TO THE LEVEL OF THE GODS!!! no.  just high enough I can watch it cause I like to watch it go back and forth while I make printer noises.

So I ordered a 3rd table.  Put it on top.  Sweet.  Much better.  I moved the printer into the enclosure this weekend (no sides put on it yet) and decided I needed to get the lighting in place.  So I took some neopixel strips I had laying around and hooked them up to an arduino.

13694706_1455593267790887_1215760066_nOk, so that’s now how I am leaving it 🙂  but it did look cool.   Now I can set the colors.  Plain white for printing.  I am trying to figure out how in octoprint to get a hook in to detect when it’s heating up.  That way I can turn the lights orange or red to indicate heating phase.

 

 

So I did a timelapse and a vid.   The vid of the whole rig setup

Here is the timelapse test print

 

I am working more on trying to get some good photo and video in with these projects too.  If you like the videos give a thumbs up and a subscribe.

Who’s That? What’s That? CCTV setup

Hello Hello again.   Recently I was chiming in on a thread on reddit regarding CCTV.  I mentioned how my cameras/cctv is setup.  Then I thought.

light-bulb-momentHey, you know would like to know this?

EVERYONE!!!!

 

 

Really.  Conversation totally happened in my head.  Told you Doctors it’s not too crowded up there.

Let’s begin!!

This all really started because of my 3dprinter…..

“How…. Huh…. But you…..”  I hear you saying it.  It makes no sense.  But Ill fix that little red wagon.

Aerial_Vista_Security_Camera_preview_featuredI love searching around on thingiverse.com it’s actually part of my daily sites to check.   So I came across this thing.   It’s a security enclosure for a raspberry pi and pi camera… WHAT?!?!?!

I know.  I thought the same thing.  I need that…..   So I started printing the parts.

2016-03-18 07.09.022016-03-18 07.48.26

Once I had it printed, I threw in my pi camera (NOIR).  The NOIR made it even better for being a security camera.  Ok, so cool.  How about software?

I was looking for some super simple camera software as there are tons of “security” camera projects out there for the pi.  I came across this one “MotionEyeOS.”   58732063Being built off the program Motion I decided to get in and test it out.  Flash the SD card and boot it up, gets an IP.   I just checked my dhcp leases on the router to find the ip, then gave it a static IP.

 

Once you have the IP just throw that ish in the browser!!  Configure your network settings ect.  But in the expert settings there is a switch.  Turn it on.

 

No seriously.  Turn it on.

2016-06-16 15_38_25-iseeall.noip.me - Remote Desktop Connection Manager v2.7

Yes I know.  The fast network camera page on the wiki looks like it kills alot of stuff.

 

The Differences

When you have Fast Network Camera enabled, you’ll notice that:

  • your motionEyeOS-based camera can reach a significantly higher frame rate, at a higher resolution
  • you can tweak many CSI camera-specific parameters directly from the UI
  • your browser will eat up less CPU at the same frame rate/resolution (it uses a pure MJPEG stream, rather than triggering every refresh from JavaScript)

On the other hand, this doesn’t come without some disadvantages:

  • no more motion detection
  • no more motion notifications
  • no more pictures or movies
  • no more overlaid text (date/time, camera name)
  • a significantly higher network bandwidth usage
  • you’ll need to forward port 8081 as well, if you want to access your camera from the Internet

 

No motion detection!?!?!   Are you crazy that’s why I am even reading this stupid page!!!!!!

 

EcstaticTightBuckeyebutterfly-size_restrictedCalm down.   Please calm down.  Can you even use that as a weapon?!?!   

Just let me finish before you use that thing!!!

So you enable fast network camera.  This lets you get some faster higher quality out of the camera.  Now here is the fun part.

I setup a VM of ubuntu and installed MotionEye.  Not MotionEyeOS but MotionEye.

BeQZIS7CEAAemgwOnce you have it running hit your motioneye server (http://<motioneyeserverip:8765)  and you will get another nice web interface.

In here, you will add a new camera, and set it up to point to your raspberry pi camera.

camsettingNow what is really cool here is you can setup a few cameras.  When I first set it up, I had 1 camera and then I found 9 traffic cameras and marina cams and what not from places all over the world and was able to plug them in.  Truly felt like a super villain being able to see everything!

Now that you have your cameras in motioneye we can now use the motion eye server to handle our motion detection.  See, I told you I would get there.

There are some cool setting here that you can do.  For example:

settings1

settings2

 

 

 

 

 

 

  • I have my video streaming setup so I can embed individual streams if I want into a web page, maybe a security camera sitemap page in openhab?
  • I have still images setup and capture when motion is detected.
  • I have Motion Detection configured that more than 5% of the frame has to change.
  • Then the fun part in Motion Notifications

I have a script configured on motion detection.


/usr/bin/notifycam.sh %t


This script is very simple.  It has 2 lines currently.  I honestly could knock it down to one.   Or I could add some additional code to handle different items for each camera.  The %t just passes in the camera ID.
57448311Ill go over that in a minute…. I SAID IN A MINUTE!!!!!!

On my Kodi media system in my office I installed this great add in called

Security Camera Overlay

It’s a very interesting add in.  You configure it for your security camera.  Well, I have mine connected to motioneye.

2016-06-16 20_46_26-ubuntudev1In MotionEye if you click on the Streaming Video there is a link in there called “Snapshot URL”

2016-06-16 20_48_34-KodiGrab that, you will need it to configure your Kodi system.

Put that snapshot URL in the Image URL field when configuring your add on.

 

 

 

 

2016-06-16 20_48_22-KodiOn the Behaviors tab, if your camera supports 16×9 I definitely recommend changing the Window width/height.  I have it refresh every half second and auto close after 4 seconds.

 

 

2016-06-16 20_37_41-KodiSo what does this look like?  LIKE THIS FOOL!!!!

It pops up right over Bob’s Burgers!!! refreshes a few times, let’s me see what’s going on and slides right back off.

 

Back to the script


/usr/bin/curl -g "http://xx.xx.xx.xx:8080/jsonrpc?request={%22jsonrpc%22:%222.0%22,%22method%22:%22Addons.ExecuteAddon%22,%22params%22:{%22addonid%22:%22script.securitycam%22},%22id%22:%221%22})"
/usr/bin/curl --header "Content-Type: text/plain" --request POST --data "ON" http://xx.xx.xx.xx:8080/rest/items/PorchMotionDetected

Explanation:

Line1: sends a json packet to my Kodi install in my office telling activating the great addon Security Camera Overlay.  This makes it slide over whatever you are watching.

Line2: sends a “motion detected” packet to openhab.  In my openhab Items file there is a simple switch I can add all my rules around.

downloadIn writing this I learned something today.  I am going to make a couple modifications in the future.

The notifycam.sh file will be adjusted down to 1 line.

It will just make the call to openhab.

But it will look something like

<pre>/usr/bin/curl --header "Content-Type: text/plain" --request POST --data "ON" http://xx.xx.xx.xx:8080/rest/items/CameraMotion%1

That way I don’t have to recode the script when I add a camera. I just need to add a new item CameraMotion<ID> to openhab.

Then I can add all the camera’s to a gSecurityCam group and build some rules around state change in that group. Then openhab can send out the notifcations to pop up the stuff on my kodi and any other kodi system I wish, as well as send me notices through other openhab notifcations.

I hope this was long enough for you…
