Starting a Tkinter App on top

August 8th, 2011 by tekromancr received No Comments »

I have been building a Tkinter App using python, but whenever I run python MySweetApp.py I ran into an issue where the app would appear behind my terminal window. This, of course, led to no end of frustration as I had to tab into the app window just to see if the changes I had made had the expected result. 10 mins worth of google searching later, and I found one line that will fix ALL THE THINGS!

root = Tk()
app = App(root)
root.wm_attributes("-topmost", 1) #this line sets the root object as the topmost window
root.mainloop()

That fixed my problem. Now every time I run the script, the app spawns on top of all of the other windows.

Arduino powered robotic webcam

June 29th, 2010 by tekromancr received No Comments »

This sunday, the studio that hosts FAIL had an open house, so, to show off some of the things we have been doing at out little hackerspace, I decided to hack together a fun little robotic webcam for the guests to play with. The controller was just a cheap off the shelf xbox 360 controller. The whole project took around 5 hours and is powered by python on the display / control side and an arduino on the servo/camera side.

Playing with Django, or “Fun with Sms gateways”

February 2nd, 2010 by tekromancr received No Comments »

So, I have been playing with the Django framework as of late. Every time I start toying with it, I am stunned at how wonderfully simple it makes complicated tasks. I haven’t done anything too cool with it yet, except for this. It isn’t much, but works as a neat prototype for something I have planned. And with that, here is a list of email-to-SMS gateways for most American phone companies.

FAIL for the win! (or on the nature of µackerspac...

I am excited to say that the first official meeting of the Free Association of Intelligent Lounging will be held at the Raw Deal (click for map) at 7:00pm on 01/27/10. This meeting will kick off a (hopefully fruitful) experiment in small scale hackerspaces (a.k.a. µackerspaces or micro-hackerspaces). I really hope to see as many people as possible there! More on the idea of a µackerspace after the break.

MERDE!

So, wow, this sucks. Today was freeday at sparkfun. They were offering 100 usd worth of products to everyone (up to 100,000). I spent a great deal of time assembling my shopping list, doing research, finding out what I might need to build TTTC. I even woke up early to make sure that I was able to get on the site. For 3 solid hours I was unable to connect. By the time I got on, they had ended the giveaway. :’(

I was really counting on making use of this as an opportunity to learn a lot more about electrical engineering, and microcontroller programming (not to mention that alot of that would have made TTTC happen a lot sooner). But, I suppose I will get over it. TTTC will still happen, albeit much less quickly.

I am still looking for help in regards to circut design, so if anyone knows a fair deal of analog electronics, contact me, okay?

Are you creative? Do you like to make things? Would you like to learn to make cooler things?

Than F.A.I.L. needs you!

I want to start an informal study-group in the Menomonie area for technically minded people. The idea is that we will meet periodically, share skills and knowledge, converse, and generally have a great time. All are welcome. I plan on holding meetings once a week at Raw Deal.  Drop me a line in the comments if you are intrested, and for god sakes, spread the word, people!

Tick-Tock Ton Coeur

Black and white heart cage

My next project:

A gear powered mechanical heart!
. . . sort of.

Actually, it will be a wearable mechanical heart shaped heart rate display. The project is comprised of three parts.

1) The Heart rate monitoring unit.
I plan on accomplishing this with a home made pulse-oximetry unit. This works by shining high intensity IR-light through the skin and measuring the amount of returned light. Conveniently, the amount of light returned coincides with the rising and falling of ones heart rate.

2)The filtering/processing/amplification circuitry
This part I am a little bit less clear on. Obviously, I need to process the signal in such a way that the motor in step three spins ever so slightly every time a pulse-beat is detected.

3)The motor/heart/gear assembly
This is the part that is visible to the world. A motor, passed through the back of the heart shaped case, spins a gear inside, hopefully in time to the wearer’s heartbeat.

The heart shaped case (according to the seller) is 27mm, so I need to find a slightly smaller gear (preferably brass) to fit inside of it. I am guessing 18mm just to be in the safe side. Any one know where I can make/purchase such a gizmo?

I have a pretty good idea how I am going to pull steps 1 & 3 off, but my lack of electrical engineering knowledge leaves me at a loss as far as number two is concerned. If all else fails, I could just dump the input onto a lillypad arduino, do signal processing that way, and then control the motor from the arduino.

First!
