3d Printing Problems on the Replicator 2's

Was finally able to complete a print of the infamous shift knob this AM.  Used Adam vice Eve this time and tried something completely different.  I mounted the (white) filament on Eve and strung it across to Adam.  It was much easier to monitor the slack and several times detected overwraps that would have not have been seen behnd the machine.  I suspect that even minor tension on the filament will cause the type of problems I have been having.  A good solution might  be to mount the reels on the wall where they can be better observed and controlled.  You definitely can't walk away and hope

HERMS Progress

Hey MakeHaven,

Just wanted to let everyone know we have several updates to the HERMS project page.  Have a look to get up to speed.

We're still refining the process, but we're also making beer.  I was considering scheduling a brew day to introduce people to the project, and get them some time using the machine.

Arduino Matrix

My computer science teacher and I are trying to make and program an led matrix, (possibly like 5 X 5 or a little bigger). We started off with a scrolling 1 X 5 led matrix, but that the letters were pretty difficult to read and it was too simple, so we moved on to a srolling 2 X 5 matrix. However, that was still pretty dificult to read and didn't look great either. Neither of us have much experience with the hardware for excedding the maximum number of output pins.

Sound Absorption / Treatment

 

I recently moved from an apartment on a noisy street to a different apartment a few blocks away on the same noisy street.  I have wanted to work on a few musical projects that involve recording live instruments, vocals, etc, for some time.  The loud nature of my living quarters has made this impossible.  In my studio in the new apartment, however, is a rather large closet measuring 5.5' x 4' x 8.5'.  It is not luxurious, but it is more than sufficient for a vocal/small recording both provided it is treated properly.  To get it to a useable state, it will require some bass traps around the sides, some treatment on the door, and foam around the sides and on the ceiling.  

Tool envy -- Shapeoko

I love robots. I love computers. And Im starting to love tools the more I get to try to improve on my n00b skillz. So when I get a chance to see tools and computers together that I can have access to in my own house, garage, or makerspace that I am happily a member of,  I think this may deserve a look as something to add to the space.

C2000 LED Experimenters KIT

 

So I got this C2000 LED Experimenter's Kit from my Texas Instruments representative.  I have it setup on one of the PCs running the color light demo.  Everyone feel free to mess with it, the documentation is in the box next to the PC.  The kit itself supplies a license for developing on the kit via the USB. The kit includes a Piccolo microcontroller which has dsp functionality.  This may be a useful platform for the sign contol, and they have reference circuits for powering the LEDs.
