This project is a wonderful example of what can be accomplished with a rather complicated logic circuit. It's an Etch-a-Sketch made from a 16x16 LED grid. That in itself is only somewhat interesting. But when hearing about the features and that it is driven by logic chips we were unable to dream up how it was designed. There's no schematic but the video commentary explains all.
Hey guys the other day one of the members who are working on the Redbull project was talking about a Fire piston. I had never heard of this, so I decided to do some research. I found a video of one that is made of acrylic and really easy to make. I go camping alot and a way to start a fire without matches or lighter is something that would come in handy.
Starting the project I needed to figure out how to interface a RFID reader with the Pi. I wanted to interface it with the UART pins but due to time constraints I ended up using a sparkfun USB adapter with my Innovations ID-20 RFID reader. The only thing I has to do was monitor the USB in /dev and receive the RFID tag ID when someone scanned their card.
The package arrived from redbull today, and almost got sent back because they forgot to put my apartment number on the address label. Luckily I stopped by the post office to check on it. And OMG.
Over the top laser cut packaging.
Crazy long addressable rgb strips.
So many IC’s to learn, someone should post all the datasheets.
We’ve got until May 5th to make our creation and we’ve got to make a video of it less than 3 mins so minimal build video. We’ve got a plan which we think will blow people away but I don’t want to give anything away so our competition gets a heads up so ask Kyle or Me. I’m working on some stepper motor controls and this weekend we’ll start construction. Let’s do this!
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!
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.
- 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.
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.
Here is a quick vid of my new MAME machine. I do plan on doing a full writeup on the process I did to make this, but for now here is a video.
Cornell University researchers have been pulling all the tricks out of the bag for this one. By using living cells in a collagen gel as the printer’s “ink” the printer layers the gel into just the right ear shape for cartilage to cover, without having to make a mold first.
