Hi. I need some maker advice. I am making a fountain. The structure and shape of the fountain is plywood. I had planned on using some leftover mosaic tile I had from my kitchen but am unsure of how to bond it to the plywood so that it's waterproof. I treated the plywood with sealant and then tried to apply a thin layer of portland cement to all the surface area first but it didn't bond to the wood and just dried and flaked off very easily. How should I go about doing this? Many thanks in advance for any advice offered!

You need to cover your plywood with chicken gaas. Then cover that with cement. Then you have a good base to stick your mosaic to...

hi folks, 
I want to build a camera jig (pan tilt and slide) for my local church.
It is going to be motorized, and I need some tips and help along the way. For example designing control system and choosing motors, gears etc. 
Anyone keen to help? :)

I'm not sure this is the right forum for finding you a solution. Someone is welcome to prove me wrong, but you might want to try the support section here:

Call for participants, Build a racing sculpture.

A feature of Cambridge River Fest in the 80's, is returning from a long hiatus, http://sculptureracing.org   Creations were pushed, pulled, and occasionally pedaled on a course of up to a mile.  Pieces would stop and give little performances to the crowd.  Outlandish trophies were awarded.  Tongues may have been planted in cheeks.  Crowds were over 100 thousand strong.

The Artisans Asylum has been asked to build and race an entry in the re-inaugural event on June 6th. Here is a chance for the Asylum community to build a large and somewhat silly piece of art, and show their work (and the Asylum's name) off to many thousands of people.  An object almost as big as Stompy, but providing near instant gratification,  as it will be weeks rather than years in the making.

Starting on April 12th with an "organizational" meeting, and continuing Sunday mornings  till mid to late May, will be an open building event.  This isn't a class, its a project.  If you are a member, participation is free. (If you aren't a member, you are still welcome to participate, and a 5 pack of day passes should cover things)  Festivities will be from 10 am till around 2 PM, in the Tardis (aka MPR2).  On April 26 instead of building, we will be part of an exhibition at the MIT museum, a "Signature" event of the Cambridge Science festival, showing drawings, some work in progress, etc.

To honor the tool using focus of Artisans, and in a nod to another racing event that used to take place in Somerville, the plan is to build a scaled (up) super-modified class racing belt sander.  The finished machine (and the first order of business is coming up with a name for it) will be 10-15 feet long, and 5' wide.  We will be building it out of foam, with a metalized mylar (space blanket) skin, on a frame of steel and wood, with bicycle based running gear.


The prototype is an  early 60's model known to collectors as a "locomotive" style. Its going to have a whole bunch of sponsor stickers, like any good dragster, wheelie bars (that double as the push point), flames on the nose, and the ugliest piece of shag carpet or critter fur I can find as the sanding belt.

Here is a chance to figure out how most theatrical props get made, but this is for more than the foam carving brigade.  Costumes would be a great thing, and an area which I am completely clueless.  The machine could use lighting and sound effects.  Skunk, could SCUL come up with a Disco ball to replace the knob on the front?

I have a question for the people who are probably smarter than me. I am writing a pythonscript that I want to use to control my servo with just my 3.5m audiojack. I have a quickly written up script that will wait for a command and just print "Success! moved to Position here" But Now I need it to actually send the waveform through the headphone jack. Sooo how can I generate those? Can a pythonscript generate the 50hertz signal needed to control the servo? Can i generate the signal for each stage, and have it play a certain soundfile depending on what I am asking it to do?

Thanks for the help in advance!

True.... Alittle crude but if it works without too many bugs not a bad way to do it.

I've a pet project that I've been working on for a long time, but I've reached an impasse. To continue, I need some self-extending/retracting telescoping rods, which operate in concert. I've come up with some designs, but I wonder if I'm not over-complicating this; I don't want to reinvent the wheel, and it seems like such an object should already exist, even if I haven't been able to find anything online. Does anyone know of a store or vendor that sells something like that? Or have a link to instructions for making such a thing?

Look for "linear actuator", or "threaded rod".

This is probably mostly a 'problem' in my area... I love to create stuff out of discarded things, scrap and waste.  But there aren't really 'junk yards' around any more.  

Where in the San Francisco Bay Area can you get inexpensive/free materials?  I'm not afraid to dumpster dive, but even there, the resources are slim pickings in an area that recycles so assiduously!

Hi, I am trying to buy or create a wireless-enabled interface for my LED can lights. The light has a 2-wire connector between the socket and the light. I was hoping to create something basic to allow me basic on/off and dimming functionality. 
Any ideas?

If you want the simplest solution, just buy a zwave home automation switch...look up infineon maybe I think they have dimmable switches.

If you want to build it, and don't want to get too embroiled in the ESP8266 and all that stuff, then a good solution might be the sainsmart relay boards.

http://www.amazon.com/SainSmart-Channel-Arduino-Mega2560-Duemilanove/dp/B00B17HMXE/

That, plus an Arduino Mega 2560, and a wireless module should have you pretty much set for on/off. But to be honest by the time you've bought all the bits you'll have spent as much as the infineon switches.

Dimming is more difficult and might require you go build something more custom. This is a pretty good guide to that http://www.alfadex.com/2014/02/dimming-230v-ac-with-arduino-2/

You'll have to learn a whole bunch about AC power ;-)

Looking for someone in Los Angeles knowledgeable in electrical engineering to help realize an artist's museum installation project. It consists of tiny Chinese firefly-circuit LED globes which need to be wired together and mounted at the ends of rigid tubes which are in turn mounted on boards running up a stairway. Send me a message if you're interested in working on this project.

shopvac vs fan
I was looking at DIY cyclone separators for a shop vac.  If I made a cyclone separator and hooked up a box fan to suck air through it, would that work?  A shop vac pulls about 140 CFM but a box fan does about 2000.  What I'm not sure about is, will the box fan give up as soon as there is an air restriction.  Might give it a try but thought I would throw it out there to see if anyone sees a big problem with it.  I would put a air filter or two before the fan so anything that makes it through the cyclone doesn't clog the motor.

Hey all - I've been practicing on a Trotec laser engraver, really liking it.

Wondering if there are any useful forums or communities for laser stuff - I'm trying to figure out how to do bas-relief in wood from photographs.  Thanks!

Hey folks ... can you spare a minute please ...

At the KC Startup Weekend EDU event one of the groups is working on a Mobile Makerspace ... I know that this group has some feedback.  The form is geared towards educators but they really would like the Maker Community feedback too.

Can you help them get over 100 individual data points?
