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!!!!

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.

OpenHab Wall Switch

So recently I started thinking about my HA system when I have guests.  I have a small house (not a tiny house) just a small house.  When my parents visit they setup camp in the living room.

vYtvpWpWorking on getting PIR motion sensors to turn things on and off.  But with guests, I need a guest mode to disable the motion sensor…. and not because I tend to dance in front of the motion sensors.

 

 

89b1c00006954836a703dfc0457c8626But with the motion sensors disabled.  There still needs to be a way for the folks to control the lights.  So I started thinking.

What I came up with was physical buttons, pass something to mqtt, then to openhab.  Openhab rule to control “group” of lights aka living room.

So time to start proto typing some things.  First I wanted to see if I could somehow make it work without putting holes in the wall.   WAF = 10 on that one.

2016-06-12 17.31.52So I started by 3d printing a light switch blank panel.  It’s a rough print, but needed to see if I could make it deep enough to put some triple A batteries to run it.

Once I tested some depth I was happy.

Frank-GrimesNext to build build some electronics.

 

So I broke out the good old arduino uno.  This is my go to for initial builds even though I usually end up with a pro mini in the end.  The uno is a great test bed.

So it started out with Uno + Ethernet Sheild + 2 buttons.

2016-06-12 12.53.39-2

 

I ended up adding just a notifcation LED just so I know once it’s connected to MQTT since I am not watching via serial monitor now.   2016-06-12 17.34.42So what does this get us now?  Well.  It boots up.  You press one button, all the lights in the living room turn on.  Press the other and they turn off.  I know what you’re thinking.  So what?

One of the lights is a phillip hue light.  The other is controlled via z-wave.  So how did I do this.  Lets start with the item definitions in openhab.

//Group Definition
Group gLivingRoomLights

//Items
Switch Switch_LivingRoomStandingLight "Living Room Light"     <light> (gLivingRoomLights,gDashboard) { zwave="2:command=switch_binary" }
Switch LivingRoomTableLight   "Living bulb" (gLivingRoomLights,Switching) {hue="1"}

//Dummy ITEM that is set via mqtt
Switch LivingRoomLights "Living Room Lights" {mqtt="<[mqtt:switches/livingroomlights:state:default]"}

So in my items file, I have the 2 light items and a dummy switch.  Notice the 2 light items are in the “gLivingRoomLights” group.  This is important.

Now for the rules.


rule "Living Room Lights"

when
Item LivingRoomLights changed
then
if(LivingRoomLights.state==ON)
{
gLivingRoomLights.sendCommand(ON)
logInfo("All Living Room Lights","ON")
}
else
{
logInfo("All Living Room Lights","OFF")
gLivingRoomLights.sendCommand(OFF)
//off
}
end

So this rule is triggered when the Dummy Switch (LivingRoomLights) changes.  If the state was changed to ON then i send the “ON” command to the entire group.  Same for when I turn it off.  So to test it I used mqtt-spy and manually did it.  All is working.

k16232506

What’s next is I am going to work on shrinking said project down to using an arduino pro mini, 2 AAA batteries.  For the network transmission I am back and forth between 2 options.

  1.  esp8266 – using the esp is great, but it’s not very forgiving on power.   I know there are deep sleep modes, but they aren’t really good for what I need with multiple buttons.
  2. nrf24l01 – RF modules.  These little suckers are really easy on the power.  If I use these I have to build a rf->ethernet bridge.  But with these I think the power consumption is much simpler.

Either option I go with, I can use a pro mini and have 2 interrupts I can attach to buttons.

Down the road if I need more buttons, I can use a pro micro and get something like 14 interrupts and still be able to use deep sleep.

iphone-battery-iconIf I wanted to cut holes in the wall and run cable I wouldn’t be as concerned with the battery levels.

 

 

 

Want to see it being tested?

 

 

Traffic (actual cars) Woes

So in the last 2 weeks I have been put to the test of patience and road rage.

giphy

Last week there was a guy that decided to take his dog for a walk on the over pass and decided to stop and contemplate jumping.  This closed down a 3 lane highway and the 2 joining lanes completely in morning rush hour.  Diverted traffic was diverted to a 1 lane exit.  I sat in traffic for 3.5 hours!!!! At that point I called the office and said “i’m working from home, it will take me hours to get there and 30 minutes to get home.”

That was pretty rough.

This past week was obviously not as bad.  But 4 out of 5 days this week my normally 45-50 minute commute was 90 minutes.

So normally I spend 4hrs 10min on the road commuting in the morning and roughly 5 hours in the evenings (traffic gets worse)

But this week was almost 7 hours in the morning and 5 in the evening.

12 hours……

I don’t think you heard…. 12 HOURS!!!!! Just driving!!! It’s stupid.

traffic-zzz

 

Man I could get a lot of work done driving a tesla!

 

 

 

So I had this dream this week, very strange I know, and some of the details I am omitting here because well… some of it was quite sexy…. but that’s not the part I am hiding.  There was another device in my dream that I have thought about making before and in my dream I had it done.  But it had a new feature…. it told me if my drive to work was going to be longer than usual……

I know I know.  “Just watch the news you jackass!”  I can hear you all saying that.  However I cut the cable many many many moons ago.  I don’t get the news.  Two.  Well, my past brain problems have led me to a life where I don’t watch the news often because the news is generally bad and I find myself a much happier well adjusted member of society if I don’t watch the news in the morning.  But I got side tracked.

So after the wife telling me
Untitled

I decided to look into this thing that my brain was hinting at.  So I spent some time looking for mapping/navigation api’s.  I found out that TomTom has one.  Pretty good to, you can tell it what kind of vehicle you have, and if you want traffic to be taken in to account and all kinds of stuff.  So I got an api key and started coding against it.  Pretty neat.  68747470733a2f2f646c2e64726f70626f7875736572636f6e74656e742e636f6d2f752f343034323534372f746f6d746f6d2e706e67

But then I found this.  This turned out to be pretty interesting by itself since I currently use a dashing dashboard for a few things internally.

I set it up for myself in dashing and it works nicely.  So we are close, but not quite what I am looking for.

So I decided to keep working, and thinking, and eating chips.

Wait.  No chips.  Just working and thinking.

I decided what I needed was 2 fold.

  1.  Traffic time must be in my Home Automation system so I can create rules based on the time.
  2. The times must be stored somewhere so I can get a new idea of “average” drive time.

I got it.  Create an item in Openhab.  Update said item periodically.  I already have openhab mysql persistance enabled.  This will work.  I will be able to run data reports based on time of day (aka MORNING during the week) and see what the average/no accident drive time is and over time even see how much time an accident add’s to my trip on average.

So now in my openhab I have the following ITEM configured in my home.items file.

Number WorkDriveTime "Drive Time [%s minutes]"

and in my home.sitemap file

 Text item=WorkDriveTime

I have a cronjob that runs every 5 minutes that just fires off a php file to get the tomtom info, convert seconds to minutes, round it off and update openhab.

My simple php file is here.


<?php
$string = file_get_contents("https://api.tomtom.com/routing/1/calculateRoute/28.3852,-81.5639:33.8121,-117.9190/json?routeType=fastest&traffic=true&travelMode=car&key=YOURAPIKEY");
$json = json_decode($string, true);


$DriveTime = round($json["routes"][0]["summary"]["travelTimeInSeconds"]/60);

if ($DriveTime != 0) {
sendOpenHabUpdate("WorkDriveTime",$DriveTime);
}


function sendOpenHabUpdate($item, $data) {
 $openhabserver = "http://192.168.2.90:8080/rest/items/" . $item;
$options = array(
'http' => array(
'header' => "Content-type: text/plain\r\n",
'method' => 'POST',
'content' => (string)$data,
),
);

$context = stream_context_create($options);
$result = file_get_contents($openhabserver, false, $context);

return $result;
}


So with this now running in my crontab I have my database slowly updating with drive times.

Oh. If you want to get a key for TomTom yourself just go to http://developer.tomtom.com/

So what do I have in store for this. Well, there is another value that comes back in this specifically related to “delay from traffic” so I may add this in as another number item to track. But the plan is to know before I leave the house if I should take a regular coffee or a giant coffee to get me through the morning commute. download

New Firewall Status!

So a couple weeks ago I wrote about the new firewall setup.

Quick update on the status of that.  I built it out.  Got it working.  yay!

294989But I want more cool stuff.  So I have a business class fiber line run to the house with 5 static IP’s.  So I decided to see if I could get pfsense to do failover router.  You know, because why not.  I tried to get pfsense to install on this old thin client I had.  No go.  WAY TOO OLD!!!

So I moved on.  I too my esxi box and with the second nic ran it to another small unused switch of mine.  I then configured esxi with a second virtual switch that uses that NIC on the new physical switch.  I know, I could do that with vlans.  Duh!  But I am waiting for a cable for my switch so I can configure said vlans.

vSphere ClientSo with this new physical port I was able to build a pfsense box in my virtual environment.  I configured it with dual nics, 1 in each switch.  As you can see here.   My routers are named voot1 and voot2.  Named after the voot runner from the show Invader Zim.   My main network scheme is based on characters and vehicles from this show.

So now I have a physical router configured with one of my public ip’s   x.x.x.253.  Internal its configure as x.x.x.2.  I then configured my CARP ips.  You create a virtual IP for both lan and wan.   External is x.x.x.250, internal is x.x.x.1.

pfsense - New Page (1)

Set the outbound nat to use the .250 address and we are golden.  Setup all the carp sync settings to push the settings to the backup pfsense.  This works BEAUTIFULLY.   I was so amazed as how easy it is.  I just make a change pretty much anywhere in the main router and its automatically sync’d to the backup.

Once the backup is sync’d it’s time to test.   Reboot the primary.  Network dropped and didn’t come back up until the primary fully booted…

stewiegriffin-familyguy

Ok.  I got it.  The arp change caused some problems with the esxi side.  There is a switch security feature that blocked it.  You have to set the switch to accept promiscuous mode….. $%^& I think my switch is a slut.samantha_jones_promiscuitypromiscuous

 

Ok.  So now that my switch is acknowledged as a slut, it works.  Reboot primary router and the backup comes online, takes over the gateway x.x.x.1 and the external x.x.x.250.  This is awesome for various servers that I have in different datacenters that have ip security configured.

So this all went great, but the original reason for the upgrade was my old hardware choked itself out with my ipsec tunnel to AJ doing the encryption/decryption.  So we need to get the tunnel back up.   We got some time over this weekend to get the tunnel working.  We now copy back and forth at 30mbps.  30!!!!!   Fully maxing my fiber line over a secured tunnel and my cpu was only at 25%.  WIN!!!

 

BUT!!!!!! We have this awesome failover working…. will the tunnel come up on the backup too?   *checks the backup router* well the ipsec tunnel config was sync’d.  So what happens if I reboot the primary now….

NO EFFING WAY!!!!!  My tunnel re-establishes to AJ on the backup router too!!! HAHAHAHA this is awesome.

So Aj had asked me about a raspberry pi project on friday called pi-hole.  From the website..

“The Pi-hole is an advertising-aware DNS server that prevents ads from being downloaded. Once installed, configure your router to have DHCP clients use the Pi as their DNS server and then any device that connects to your network will have ads blocked without any further configuration. Alternatively, you can manually set each device to use the Raspberry Pi as its DNS server.”

But it seems like something that screams virtual machine.  I didn’t want to tie up a raspberry pi just for dns.  Turns out pi-hole doesn’t require pi hardware.  So it is possible to put in a vm.  So I configure a tiny ubuntu server and install pi-hole.

curl -L install.pi-hole.net | bash

Very simple.  But it works.  So I build out the vm.  Export it as an ovf and ship it off to AJ over the new tunnel.  He brings it up in his virtual environment and gets it working on his end.  Now to update our respective DHCP servers to tell our networks to use the new adblocking dns.   But… what if it’s down.  Ads/banners coub-1137363

There is a tunnel…. use each others as a backup!!!  Beautiful.

No my pi-hole is the primary on my network, AJ’s is secondary, and if both are down for some reason the network defaults to google.  services_ DHCP server

How well does pi-hole work?  Why do I keep saying pi-hole?  It sounds dirty.

pi-hole pi-hole pi-hole pi-hole pi-hole pi-hole pi-hole pi-hole

Yep.  Still sounds dirty.  But I got distracted.

Pi-hole Admin Console

That is insane…. 1726 ad’s blocked today.  We were gone for 4 hours and it’s still that high.  Crazy.  But you should see some sites without their ad’s.   Interesting.

This week/weekend has been pretty cool for getting some network stuff done.

 

New Firewall Build

So I have been running my home network on a home built router for well over a decade now.    Many moons ago when I lived in my apartment a client of mine was working on converting Eckerds to CVS stores.   As part of said conversion he had a ton of this little MaxTerm thin client machines.

3759951495_91064ca6e9

Which was not bad at all.  It has a little bit of memory, enough cpu to run as a router and an expansion slot.   Throw an extra network card in there and there you go.  Next to no power router.  I have been running http://m0n0.ch/wall/index.php since the beginning.  M0n0wall is now a dead project.  It will be missed, it sparked some of the great pieces I use today.   pfsense, freenas ect.   I have the last version on my little thin client and it runs well.

geek-is-coolBut like everything, eventually you run into something that makes you move on.  I had this recently.  Remember the great data apocalypse of 2015?  Well, that has sparked many changes in my backup replication plans.  One being that a buddy of mine and I are building secondary NAS systems for our freenas to put in each others server racks.  Yes, my buddy is a geek too.  So as part of this secondary nas setup.  We are going to be doing replication across the WAN.  Even though it uses SSH communication to do the replication.  We both felt doing an encrypted tunnel between locations was better.  Plus would let use gain access to each others resources without having to open unnecessary ports.  So we setup a nice encrypted tunnel.  Time to test some transfers…..

150kbs a second……..What-Meme-13

Now I never said I was a smart man.  But there is something wrong there.   AJ’s wan is 150/150 MEG!!!! (thank you FIOS) and mine is 50/50 also on FIOS!!!

No no no.  No sir, I do not want another.  I want the one I originally asked for!!!!!

Who broke that chair!!?
images

Ok.  I am calm now.  WTH is going on.   Checks the traffic graphs…

That’s not it.

Checks CPU graph on thin client….
hell-fire-1

Stops file transfer and checks again….
i_call_upon_the_power_of_ice_and_snow_by_fromzerotohero-d60aqs9

What the hell!?!  Now who broke THAT chair!!!!??

4565396395_c89b9c22f3_b

So it would seem that doing the encryption is causing a problem.  The cpu is just choking on the encrypt/decrypt over the tunnel.  That kind of sucks.  However we are also running on an old piece of hardware (12 years old?) and running on and EOL firmware.  Ok.  New Router time.

So this weekend I begin working on my new pfsense router.

Using this Intel D2500CCE Atom D2500 Dual LAN motherboard.

51mMt8cv6CL

Amazon

With a 2 gig memory chip this is ready to go.

I will post an update after I have this in and running for awhile and testing the encrypted transfers.  To see if it really is all in the cpu.

Some projects and upgrades

So I have a few things on order coming from china for some various projects.

I figured since I haven’t posted much lately I will post some pre-project dribble.

Phoenix Connectors – Aliexpress

phoenix connectors I have these coming to be able to connect audio up to my ClearOne XAP800.   ClearOne XAP-800 Professional Audio Conferencing System Pic 4 xap800_l

The XAP800 is going to be added to my Home Automation system to be able to control/mix/route audio from various sources to various destinations.  If you want to read more about what this can do check out my buddy here.

3d Printer Upgrades

Its funny.   The whole time I have had my printer I have been constantly wanting to upgrade.  Maybe because I built my printer from a kit and know each piece.  I look at upgrades thinking, this will help just a tiny bit more.  This will make it a tiny bit better.  But also, I enjoy these projects.  So I have what I can only hope are my last big round of updates.  Nevermind.  I just thought of one more.  Bowden extruder…. but that’s for another post.

Motor Coupler – Aliexpress
The motor coupler is going be to used to connect my 5mm drive shaft to my below 8mm threaded rods.

Lead Screws w/ Copper Nut – Aliexpress
Replacing my current threaded rods and nuts with some nice thick Lead screws and longer copper nuts should add some additional stability and durability in that I won’t have to replace the nuts regularly like I do now.

Aluminum Build Plate – Aliexpress
The aluminum build plate will replace my glass bed.   I have hard it does well for heat distribution but also I need it for the below proximity switch.

Induction Proximity Switch – Amazon
I am going to get rid of current auto level setup.   I am going to the inductive sensor so there is no longer going to be a swinging arm.  This will hopefully improve start up time, and keep better accuracy.

20 555 Timers – Aliexpress
ne555I have these 555 timers coming because I plan to use them on a small solar charge controller project I need for my Green Sprinkler system Project.

 

100 Optocouplers – Aliexpress
111781498246_1A couple weeks back I designed and tested a small circuit that will detect when the 12v accessory line in my car is turned on and off.  Using these optocouplers I will be able to use this signal to either power on my raspberry pi in my car, or to tell it to turn off.  This is going to be useful so that the pi doesn’t turn off as soon as I get home, but will be signaled to turn off in about an hour.  This will give enough time for sync jobs to run, backups and any config changes I want to do.

So there it is.  Some of my up coming projects

  • Big Printer upgrade
  • Solar Charge Controller
  • CarPi Power circuit deally (i need a better name)
  • Green Sprinkler System
  • Home Automation Audio Router
