Redbull Creation Contest 2013 Here we come!!!!

Posted: April 14, 2013 by kwood94xj in Events

This year UmmDorian was awesome enough to enter us into the 2013 RedBull Creation Contest. This years hardware is called the TURBULL ENCABULATOR!!

“The TurBULL Encabulator is our very own super simple, but extremely complicated, multi-function circuit board designed to give Makers a powerful tool in the creation of controllable LED lighting art and inventions. The Arduino-controllable board features a tri-axis accelerometer, temperature control sensor, as well as a 2nd generation reciprocating dingle arm (no, not really) in a Bulls and Sun shaped circuit board.”

Our TurBULL Encabulator is in the mail and should be here very soon. Stay tuned for more updates!

Programmable Power Supply Kit.

Posted: March 20, 2013 by kwood94xj in Bench Tools

Recently I was in the market for a new adjustable power supply. I searched all over for reasonably priced full featured PSU. I was considering going the hacked computer PSU route, but with its voltage maxing out at 12VDC it would not fill all my needs. Then I stumbled on this kit. It is a very well designed board based on a Atmega8 chip.

It features

  • A 16×2 LCD that displays the set voltage and current. it also displays the actual voltage and current.
  • A 5 button control interface to set the voltage and max current. There is a Store function that will save the current settings and re apply them on power up.
  • You can build it in many different voltage and current configurations. (22VDC 2.5A or 30VDC 2.0A are the standard configs)
  • Very low part count and all the components are through hole making it easy to assemble.
  • With the optional DDCP to USB kit you can set the output voltage and current with your PC via USB

The price of the kit is also very attractive at $31.99 it is a bargain. All that you need to add is a Atmega8, an 16×2 LCD, Heatsink, Transformer/Rectifier, and a Case.

The DDCP to USB kit that allows computer control is only an additional $17.20

I will post pictures of it in action along with a full review when I have completed the build.

Welcome ummdorian!!!!!!!!

Posted: March 12, 2013 by kwood94xj in Hackerspace News

I would like to take the time to introduce our newest member to the Blog ummdorian. He brings extensive skills in web design and micro-controller programming. I personally look forward to his contributions to the hackerspace community.

Drones For All!

Posted: February 21, 2013 by kwood94xj in For Fun

There has been a good bit of talk in the media as of late about Hobby and commercial drones. Debates on there regulation by the FCC and how they relate to surveillance on U.S. Citizens. There is a great group of people over at DIYDrones who make a arduino based Unmanned vehicle board. I have been following the project since its first board was designed. There newest version is nothing short of astounding. Not only can their boards be used on R/C Aircraft but also on R/C boats, cars, helicopters. Check it out and build yours today before the laws change and make it more difficult for hobbyist to comply.

Homemade X-Ray Tube

Posted: February 11, 2013 by kwood94xj in Misc Electronics

Today I was looking thru Ron Soyland’s Youtube Videos (Glasslinger) and saw a awesome video of him making a very small working X-Ray tube. This guy is absolutely amazing. His videos are fun to watch and very informative. Check it out after the break.

 

H-Bridges

Posted: January 27, 2013 by kwood94xj in Events

The other day someone asked me about building a large H bridge to power some 25+ amp motors. Well after finding this Tutorial I then researched some higher current darlington transistors. These are rated at 50A and 120V up from the TIP-147/142 rating of 10A and 100V the price per BJT is about 7 times higher than the TIP series but if you need high current there is a cost.

PNP transistor link ON Semiconductor  MJ11033G $10.29/ea

NPN transistor link ON Semiconductor  MJ11032G $9.65/ea

These transistors would take the place of the TIP 147 & TIP142 BJT’s other than that the board traces would need beefing up to handle 5x the current. Also since these are in a different package (TO-3 vs TO-220) the board layout would need to be redesigned. I would think about mounting them on large heatsinks then running wires to the board.

CNC Porn

Stumbled across this video of CNC fabrication of a circuit board. This is something I hope to be able to do with our new DIY CNC machine.

 

fink000 is in!!

Posted: January 25, 2013 by kwood94xj in Hackerspace News

I would like to take the time to welcome fink000 to the Hackerspace. He brings to the table a background in Programming, Linux, RC Aviation. We look forward to having him post updates of his MAME Arcade and RC Lawnmower.

Tutorials, Tutorials, and alas more Tutorials.

Posted: January 24, 2013 by kwood94xj in CNC

Tonight while perusing the Buildyourcnc.com website I noticed a Tutorials section. Being naturally curious I clicked it and was blown away by the amount of video tutorials. These guys have really made sure that anyone can build a CNC mill if they so choose. Keep up the good work guys.

For the lazy among us (Myself included in that) here is the link right to the Tutorials page.
