Hello to all you atoms out there!
Are you ready to get this laser going?!
You call that a response? It sounds like you’re in a ground state out there, and I’m going to need you at least two or three levels above that! That’s right, I’m going to need you to get excited tonight! Come, on let’s get this population inverted!
Hey, that’s better! It looks like some atoms in the back have a nice wavelength going – let’s all join in for a cascading effect!
If you’re digging this gain medium, let me see you get amplified!
Yeah, now you’re getting your photons in step!
What: The Midsouth Makers are hosting a laser class and demonstration! The goal is to demystify lasers and how they operate. For the demonstration, we will be etching some aluminum business cards with your designs, which you will then be able to take home with you!
When: November 19th at Noon
Where: The Space
Cost: $10 for Midsouth Makers Members, $20 for Non-Members. (The price covers both the business cards and the cost to run the laser)
What to Bring: Please bring a laptop on which you can design your business card. The cards themselves are 3.5” by 2”, and we ask that you try to come with your design ready to go, but open to changes if necessary.
Please sign-up on our events page if you wish to participate: http://www.midsouthmakers.org/events/
Great Scott! What’s the date? Oh thank goodness, we’ve still got time. Listen, I know this may sound “heavy” to you, but we’ve got to get you to the Midsouth Makers soldering class on October 8th at noon or the consequences could be dire! I can’t tell you why it’s important without creating a temporal paradox, but I can promise you that learning how to build a RBBB (“Really Bare Bones Board”) Clone will be pivotal in your future in some way. An RBBB is one of the smallest, most affordable arduino-compatible boards available right now. You don’t even need any plutonium to power this baby, just plug it straight into the breadboard that the Makers will be providing to all the class participants. How many gigawatts is it? Where we’re going, we don’t need gigawatts, just bring a soldering iron and the rest will be provided. Once you’ve completed this class, you’ll have you’re very own arduino compatible microcontroller, power cable, data cable, and breadboard to build it all on, the combination of which should help you save you from – oh no, I’ve already said too much! Hurry and sign-up on the events page at the following link: http://www.midsouthmakers.org/events/. Then you too can say, “I finally made something that works!”
Class: Soldering Part II: RBBB Clone
Date, Time, & Location: October 8th at the Space at Noon.
What to bring: Soldering Iron
What you get: An arduino compatible microcontroller, power cable, data cable, and a breadboard to build it on, plus a greater knowledge of soldering and circuitry.
You must sign-up before the day of the class so that we know how many parts to order!

Sonny recently shared his current progress of his UAV Quad Copter project and included a test flight video.
So today I had my first real flights with my quadcopter UAV. The setup is pretty advanced and it takes a lot to get up to speed. I’ve learned a lot from my build. I made custom printed PLA motor mounts, which have worked out really well to hold them on the end of aluminum pipes. Unfortunately the cross in the middle which is also PLA could not handle the rough landings and cracked. I’ve secured it for the time being, but I think I’ll be milling something better Wednesday. If I can work out the stability issues, I’ll bring it Friday. Anyway, check out the first flight/set of flights.
Ben sent me this writeup of his progress on his Rep Rap Prusa printer. Here’s his progress using one of the teensyduinos that PJRC: Electronic Projects with Components sent us.
I am currently building a rep rap Prusa 3D printer and one feature I want to add is a Graphic Display to display the nozzle temperature and the heated bed temperature. Once I had the Teensy in my hands, I rummaged through my parts bin and found a 128×64 graphic LCD.
As an Arduino newbie, I was blown away how easy the Arduino environment is to get up and running. Within minutes, I was able to get the IDE installed and the Libraries installed for the Teensy.
Using the GLCD example on the Teensy’s website, I populated my breadboard. The Crystal Fontz LCD (CFAG12864B-YYH-N) I used in the project has the NT7107C driver, not the KS0108 found in the GLCD example. The pin out on the Display ended up being different, but worked just fine.
My plans are to use the I2C output on the GEN7 Prusa electronics to send the temperature data to the Teensy over the i2c bus. For prototyping, I used the “Bus Pirate” to send i2c commands to the teensy to simulate the GEN7 electronics.
Haunted by old computer parts? Frightened by the prospect of having them go to waste? This Friday, May 13th at 7pm we’re going to break the curse of broken electronics with our first de soldering class! Come by the space and you’ll learn how to exorcise the demons that plague your old hardware by learning how to remove solder and reclaim your parts for good!
There is no cost to participate, however any donations to the group would be greatly appreciated.
You won’t need a young priest or an old priest, simply bring the following supplies if you can (if you cannot, don’t worry, we will share!):
• Soldering Irons
• Picks (dental type)
• Alligator Clips
• Solder Suckers
• Stainless Steel/Brass scrub pads
• Circuits that you wish to desolder
We will provide participants with the following items and our assurances that they are free of any bad luck:
• Solder wick
• Solder flux
• Brass wool
• Kapton tape
• Helping Hands
• Alcohol (for cleaning flux)
All black cats, broken mirrors, and open umbrellas are welcome! Sign-up at http://www.midsouthmakers.org/events
