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!

 

 

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.

Random

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

This guys has his shit way more together than I do.  Look at him!  He’s wearing a suit….  I barely wear pants!!!!

 

 

 

 

 

 

My first Thingiverse Item (Light Saber Stand)

So I owed a buddy of mine a stand for a light saber.  I took his saber and measured it up and actually designed my first real 3d design.

Its nothing crazy and will have a couple more tweaks as the tolerances are a little too tight right now.

My First 3d Printer (part 2)

Wow, its been 6 months since I wrote part 1.

I will show a few more pics of the build and then go into some MAJOR things I learned.  Some links to really good resources and some pics of various prints I have done.

2015-04-21 21.49.04

This was the picture after I got a lot of the main support structure together.   I thought I was getting close to being done.  Oh how wrong I was..

All of this info so far happened in the time between Wednesday and Saturday that first week.  So Saturday night the wife is off to work, the kids are pre-occupied.  PRINTER TIME.  2015-04-23 22.03.16

So I am putting on the heat bed the the y-carriage support (that acrylic plate in the middle.)  You have springs you put over the screws so that it has constant pressure keep the plate level.  I am pressing these things in…. crack!!

2015-04-17 17.53.20

Yep, broke a piece of my printer before I even plugged in it.

2015-04-25 14.03.51

I was devastated.  However, not the end of the world.  I continued on and just jammed a sticky note pad in there… don’t judge me.  Desperate times called for desperate measures!

At that point I stepped away for 2 days and began working on it again going into the new week.  Electronics time!!!

Now we have to hook up all that stuff.

Look how clean a RAMPS board looks before you hook everything up.2015-04-24 18.27.08

So I get everything hooked up.   I’m done.  Lets hook it to the computer, upload a test pattern for the motors and make it move.

 

 

Nothing…

 

Why isn’t it registering….  Why is that power light coming on and fading out…. Did I get a bum arduino mega?  No worries!!! I have an extra one from another project, lets test it.

Out comes the magic smoke….   1 of those little green stepper motor boards was on backwards and fried not only the arduino mega, but the mega, the RAMPS and 4 of 5 stepper motor drivers.  Thank you amazon for having just that kit available for someone like me.

 

Now I am considering just setting it all on fire, molding it into something, and calling it “3d printer art” but we have it powering up now.   So I had to give the dining room table back to the wife (she hates when I take over the table for projects)

2015-04-28 23.52.08 2015-04-29 16.48.36

So its time to start trying to print.

HA!!!  I wish it was that easy.   1 simple word for anyone considering 3dprinting.  CALIBRATION!!!!  Do it.  Do it again.  Keep doing it.

That clicking sound in the video.  Yeah turns out that is bad.   I was having problems with the motor being able to push the filament through the nozzle.

Calibrate your temperatures!  Make sure you aren’t too close to the bed.   Sigh.  This went on for awhile.

Good calibration cube http://www.thingiverse.com/thing:214260

 

Then I ran into this lovely issue.

2015-05-09 01.53.38

So much heat transfer into the extruder that it softened and jammed up.  I cleared this SOOOO many times.

Look on the top of that heat block.  See that little bit of leakage?  That became the bane of my existence.  Long prints and I would get a random build up of that plastic, it would drop on my print, cool, and snag the head.

Fixed the jamming with adjusting my cooling settings and print head temp.

Fixed the leaking head by pulling that throat tube out and putting some plumbers tape on it.  Shouldn’t have needed it, maybe it was a bad tube, but worked like a champ since.

I had another problem later with all the vibrations my heating element fell out of the heat block.  That was weird.  Had to tighten everything down again.

Thermister broke…  Replaced that.

Replaced nozzles a couple of times due to bad clogging (nozzles are cheap, order spares, you may be able to get acetone to dissolve a lot of the clogs, but who wants to wait multiple days)

 

 

My first 3d Printer (part 1)

I have been looking for a 3d printer for a long time.  Finally had a chance to get one so I did some looking around and found a great price for a prusa i3 kit.

The kit I got was folgertech.

image

The price has dropped from $299 to $289 just since I got my kit.  So the price is insanely cheap.  Especially for a US based company.

So I order said printer along with a display.

image

The kit shows up after almost 2 excruciating weeks.  I knew I had to build it so this wasn’t a surprise.

More coming!!
