New Youtube Channel for a new time

I’ve decided to start a new Youtube channel simply because I feel as though adding my projects and the things that I like to a video channel will drive me in ways I hadn’t had before. Thus far, I have 0 subscribers (aside from myself) and I’m genuinely curious to see how well I can make a Youtube channel work out. I believe I have some interesting things to share and some boring but popular things to share as well and a new Youtube channel that explores all those things.

Here’s a link to the channel

https://www.youtube.com/channel/UCwxvlEKdkh9eV9qLXHBh3fw

Not the most graceful URL but I will get a better one once I get some subscribers and I’ve been around for a while. I will explore things that I do such as electronics, gaming, machining, photography and whatever else I come across.

Here’s a video detailing something mundane, my calculator collection.

So, feel free to look at my channel, subscribe and like a video or two. 🙂

A quick post, Basic program for day length

Just wrote a little FreeBASIC program for calculating the length of the day and the difference from each. Just enter your latitude and it’ll output a text file for the length of the day and difference from the previous day.

Anyways, it’s not well programmed or anything but the function could be useful for somebody out there. Who knows

As a side note, time is in hours.

The magic of EDM machines

The other day we were asked to remove a section out of a valve. It’s not a huge valve but milling it would’ve been difficult all the way to the center so we put it on the EDM to blast out the side to make the inside visible. through to the stuff on the inside. Here are the images.

And a view from the top. gotta love the clean edges with the rough gritty surface.

Here's a look at it from the side

This was all burned at 150 amps which is max for this machine.

A look as it was being burned, not much to see

Nothing crazy interesting, but I thought it may be neat.

Playin’ with the Canon G12

This weekend I just purchased my new Canon G12. What a delightful camera. It’s robust, effective and just small enough to fit in a pocket (A big pocket)

I’ve been re-inspired to start taking photographs again since I have a good pocket camera again. YAY! I’m also playing around with some different techniques on filtering. Just an attempt at some different styles and ideas that I’ve been staying away from such as B&W and Lomography.

Here be some shots me hardies!

Krebs to Poise Formula

Looking for a decent formula on the net for a Krebs to Poise conversion I’m left empty handed. I found a chart that had listed direct numerical conversions.

Here’s the Best Fit value in the Quadratic form ax^2+bx+c=y

y=0.00419037x^2+(-0.306745)x+6.40025
y=poise
x=krebs

It may be somewhat rough, but since KU is a unitless value…

(Update Nov 4, 2013)

Got some info from a fellow in Costa Rica that the formula seems to match more closely to Newtonian Poise. Using this for Thixotropic fluids would most likely be innacurate at best! I would agree since Thixotropic fluids require specific velocity differences to accurately determine viscosity at a value differing from standard measuring techniques.

3 point quadratic regression formula

While developing the in-process stormer viscometer, one of my goals is to allow the end user to calibrate the device with 3 fluids of known viscosity. With a bit of help from mathematica, I’ve found the formula and for whoever wants it, it’s posted, also for my own future edification. This formula is meant to convert 3 data points of the form {X1,Y1},{X2,Y2},{X3,Y3} into a form of ax^2+bx+c=y. This is probably the fastest way to do this kind of operation on a microcontroller. Here’s an image of the formula

also, here’s a dirty FreeBasic program using it. regress-3point.bas

Also, for fun I decided to do a cubic version. This is in the form of 4 data points {X1,Y1},{X2,Y2},… converting to ax^3+bx^2+cx+d=y

You gotta love Mathematica!!!

Still goin’ at ‘er, now attending the self employment program

Well, no new project pictures or anything. Summer is almost here and I’m pretty happy about that. I’m going to start at a training course for 8 weeks starting May 11.
The program itself is funded through the Canadian Government or Employment Insurance. This program is geared for people who wish to start their own business but lack the experience starting one. This program also has a 4 month post-class coaching period. From what I understand, they assist with the minutia of business and get you hooked up with financing. This program also allows one to keep collecting EI through the 6 months of the training, but not afterwards.
My idea in this case in terms of starting a business is a nebulous one at best at the moment, however, I think that by lending my skills as a machinist and programmer and technical dude, hopefully I can eke out a living or perhaps even a prosperous business in these difficult economic times.
I think that this program will help give me an introduction to the business skills I lack in abundance. Anyways, hopefully tomorrow will be a sunny day, I want to do my full report on minolta md lenses.

A Drawing of a Servo, for reference.

Well, my servos have all come in for a project I’ve been working on. These ones being some cheap Chinese servos that I picked up off Ebay. Here’s a photo of one of them.

Now that I have them I guess I have no excuse in not doing the project, especially since I bought so many of them, despite them being cheap. In starting my project I’ve decided to offer a PDF of a drawing for the servo since I had no idea how big they were or what they would measure until they arrived, thus, if anyone else wants the drawing, they can use the dimensions for their own purposes.
Here are a couple of pics of the drawing for reference.

As the project progresses I’ll review the functionality of the servos. After I had ordered them I had read that they are susceptible to outside interference, especially from the likes of human contact around the housing. From what I read, this made the servo “Freak out”. We’ll see I guess, I’m going to make a standard testbed circuit for testing anyways.

So, anyways, for anyone who wants it the drawing, here’s the PDF

Hopefully someone will find it useful.

Credos/Sayings that some people seem to live by…

“With low enough standards, you can achieve anything!”

“If you aim for the ground, you’ll always hit the mark.”

“If it’s worth doing, it’s worth doing poorly and half way.”

“If at first you don’t succeed. Lower, lower the bar.”

“If it can’t be done quickly, it’s not worth doing.”

………………
Just saying…

Playing around, drawing a valve.

I was a little bored today so I decided to draw a valve. While the dimensions are entirely drawn from my head and the valve itself wouldn’t be very efficient, I like the look of gas compressor valves. It took me a couple of hours to draw but they look OK.

I didn’t tag them or describe them. There is a seat, a guard and a valve plate. I omitted the dowel pin, bolt, center nub and lock nut. I just wanted to see what it looked like in solids. 🙂

A new Youtube video

Yes, I haven’t made a new youtube video in some time. Now the video I make is a redux of one I’ve made already, namely Doki Doki Panic. The reason I redid it was because the original wasn’t narrated. This one is, for only to add some personability and add some information to the video about Doki Doki Panic.
