usb page turner foot pedal?

i have a foot pedal for my yamaha keyboard with a 1/4" jack at the end of a cable; i want to connect it to my laptop to turn pages while i am playing music; as you all know laptops dont have 1/4" audio inputs; could any one please describe a way to connect the pedal to the usb port? i have the software for the laptop to recognise whether the pedal is on or off; usb cables have 4 wires, two for data and two for power; i am assuming that i would have to use the power lines for this since the pedal is simply a switch; any info/help would br highly appreciated thank you

How to mod keyboard to use SPST switches?

I'm converting my bluetooth keyboard into a foot controller for my iPad. I opened it up today and I don't understand how the signal gets sent in a keyboard. It looks like the piece of rubber presses down to a white dot, and I don't get how that works. How can I mod this to use momentary SPST switches to send signals as if they were keys on the keyboard?

Can I use a DC foot pedal on an AC machine? Answered

I have an ancient Pfaff (German) sewing machine. The original foot pedal died in a plume of smoke. I bought a replacement electronic pedal and didn't notice that it says 200-240v. Oops! I'm in the US, so the machine has been running on AC. Will a European foot pedal work on it? The machine (from the back) plugs into an outlet in the wall. A separate cord (on the side) goes from the machine to the foot pedal. Modern machines usually use the same machine connection for both the power and the foot control. If I try it on the AC machine, will I damage the machine? Aside from the motor, this is a strictly mechanical machine.

Good source for foot switches? Answered

I'm looking to build a stomp box of sorts, and am having trouble finding a good source for foot (stomp) switches that will hold up.  Neither Mouser nor Digikey seem to have something appropriate, at least based on my searches.  I found DIYstompboxes.com, which seems to have decent enough prices ($5.00 a pop). So my question is, what's the best (taking into account reliability, speed, quality, and best deal mainly) place to get a foot switch that will hold up without breaking the bank? Also, when I say foot switch, I mean a button.  Not a pedal.

Turning horizontal linear motion into vertical

Hi guys, I have a dmx controller which is connected to two sunstrip lights which I control with my foot during gigs. It means I have to balance on one foot and slide the fader up and down with the other in order to get a swell/strobe effect. Have you any idea how I could hack it to turn the horizontal linear motion of the fader into a vertical motion (basically a pedal I can stamp on it swell like a wah) Any suggestions helpful. Cheers!

Possible to use a single foot pedal switch to activate a linear actuator?

I acquired this mechanism which I would like to modify for ease of use. The original set up uses a linear actuator and a 3 way toggle switch. The linear actuator comes with built in limit switches. The 3-way toggle is not practical as my hands are fully utilised on the work bench. I would like to modify the set-up so that I can use a single foot pedal switch to get this motion. One step on the foot switch and the linear actuator extends to its maximum length. Then another step on the same foot switch and the linear actuator retracts to its maximum. Any help with the circuitry and parts will be greatly appreciated. Thanks in advance. ROY

What is it? Is there a modern equivalent?

This is from a 1949 Pfaff 332 sewing machine foot pedal. (I believe the machine was brought to the US by a war bride.) When I tried the machine recently, it wouldn't completely stop when I took my foot off. We opened it up and found this partially decomposed multi layered 'thing'. Other than dust and dirt, it looks like the only damaged part. Does anyone know what it is? Does anyone know what a modern equivalent would be?

New drums: Kick pedal question. Answered

Greetings! Background: My xmas 'from me to me' present was a Roland TD-9K electronic drum set.  I have a concern with the drum kick.  I think I have it set up properly and it's either a setup problem or a user/technique issue.  The instruction manual says you can adjust (insert list of a bajillion variables) and 'set it up how you like' basically, without explaining how each variable effects the end result. My problem:  The kick pedal is set up as per the instructions and occasionally (every few beats) double-taps.  The hits are extremely close together, and are hardly audible if you're not listening for them, but they do exist in the midi data. (i.e. 1/64th beat later) The hammer is physically bouncing and hitting twice, it's not just spurious noise or an oversensitive pickup.  The brain lcd has a What I can adjust: Technique:  If I move my foot a bit it changes the harmonic frequency of the hammer, and it can solve the problem, but sometimes my foot ends up back where the problem exists The pedal assembly: -Spring return tension -- more tension = ability to hit faster but more effort required, problem exists everywhere from full soft to full firm. -Hammer location - it's centered on the sensor per instructions, and strikes flat and square. I could move the pedal off to one side slightly, or change the effective length of the hammer so it hits higher or lower (would change the periodicity of the system). -Angle of the sensor - per instructions is set straight vertical. -Electronic filtering - I can tell the brain to ignore hits for a period after a given hit to eliminate the spurious hits, but this wrecks my ability to intentionally use techniques where fast double-hits are wanted -'Home' angle of the hammer -- the angular moment with which the hammer moves with each kick.  Setting this too far away tends to make it hit the top of my foot (quite painful), and too short means its hard to make it work. Other Thoughts: I play barefoot, should I have a set of drum shoes?  Would that make a difference? I want to use these also to play rock band thru the midi adapter (people report its fun) -- but the double-hits would seriously impair scoring ability, and I need a way to fix them!

Wiring 2 pots together?

Ok, so I am in the hobby of hobby grade rc. I am currently working on modding a ps2 racing wheel and foot pedals to work with a spare 2.4ghz remote I have for my cars. I got the steering wired up fine and it works good. Now for the somewhat tricky part. The foot pedals each have a potentiometer in them. They share ground and power, and have separate signal outputs. I have the right one wired in for the throttle just fine. On my micro car it was easy enough, just switch the throttle reverse switch and push the pedal and it goes in reverse. But most escs wont calibrate to that. How would I go about wiring them together? essentially I want to turn 2 pots into one big pot. So when I push the right one down it sends the signal for forward. When I take off the right one and push the left one down, it signals reverse. I could bring my micro controller into the mix, but I really dont want to for something that seems so simple. Plus it is on a serb right now. Any help?  Thanks

Wireless switch , need help on how to make

OK , I am a tattoo artist. I want to make a wireless foot pedal to control my tattoo gun. This is how it works now. It has a foot pedal with a 1/4" phono mono jack that plugs into the power unit. When my foot is pressed down it simply closes the connection and tells the power unit to apply voltage to my gun which has a separate cord coming from the power unit. I would like to make a wireless for this. Maybe a simple remote control toy can give me all the conponets needed. I want it to be small , maybe a 9 volt battery supply. I can have my foot pedal  wire just 10" long going to the a sending unit with an antenna. Then alls it has to do is maybe close a relay that I can wire to a phono jack to just close the swicth to tell the power unit to turn on my tattoo gun. I know this is going to be very simple but for some reason im having trouble thinking of how to do this cheap. Thanks for the input. Jeff

Resistance Isn't So Futile

Nissan has introduced the Eco Pedal, an acceleration pedal that pushes back on the driver's foot if the driver is supplying unnecessary pressure and therefore being fuel inefficient. From Wired News: Nissan estimates that the Eco Pedal, coupled with the already ubiquitous instant fuel readout on the dash, can increase fuel economy 10 to 15 percent.While it may hinder driving freedom a little bit, it seems more like it's there to be a friendly little reminder.

Help Making Tattoo Lab Power Supply Jumper / Converter + pic

This is what I'm talking about. can you see it?  it's the first thing that comes up on google image search when you type in "lab supply jumper." It's so you can plug in a tattoo machine and foot pedal into a lab power supply.  theoretically I get how it's working.  The foot pedal is what interrupts the circut.  when you press the pedal down, it makes contact and completes the circuit.  So, the machine needs to be routed through the pedal before getting power from the power supply (versus plugging the machine directly into the PS itself.  Cause then you'd have to turn the PS on and off to get the machine to work or turn off). So, I'm assuming that's why there is a cord going from the "machine" 1/4 terminal to the "foot pedal" 1/4 term, right?  Then the pos and neg banana plugs go into the power supply. specifically, my question is this:  do I have to solder to make this?  or can I just twist wires together?  and can I buy everything I need from radio shack, right?  I'm pretty confident I can do it either way, just need a diagram or something on how to wire everything. I'm also asking my brother who was an electrician before getting injured on the job- he's on disability now but may be able to help, too. =) It's gotta be easy to make, right?!?!  so help me do eeettt!!!  =0) thanks for any and all help!  Sarah ps- I attached a pic of the power supply I have so you can see it as well. and for the record, my tattoo machine is RCA not clipcoard, but goes to a 1/4 male mono all the same.  As well as my pedal. k, thanks. ;0)

International 345 v8 engine trouble? Answered

I have a 345 v8 international engine that will not idle. It runs fine if you rev it up but as soon as you take your foot of the pedal it will idle roughly for 20 seconds before stalling. I have put a new set of points in and also adjusted the timing correctly. What would be causing the engine to not idle. Also I have adjusted the idle screw and the place at which it will run is way to high for an idle so I can eliminate this as a problem. I have taken the top of the carby and can see that both jets are squirting as per usual. It has really got me confused this one. The only thing I can think of is vacuum advance but I can't see how it should effect it at an idle. Your help would be much appreciated.

Where have all the EE's gone; long time passing......

I'm trying to upgrade the control circuit on my cheap TIG welder. The existing control is a 10k ohm potentiometer, mounted on the welder. It's wired up such that the voltage drop across the pot is proportional to the welders output. Instead of having one knob that controls the output, I want one knob on the welder's panel that selects the maximum output, and another knob ( to be mounted in a foot pedal control) that allows me to select output power from zero up to the maximum value that is set on the panel knob. Seems to me that there should be a relatively simple, elegant solution that gets covered in the second year of an electrical engineering course. Or am I just insane to think that such a thing should be simple? I've tapped out my own social network, and I can't find anyone who will admit to being an electrical engineer. Thanks.

I am looking for a rotating carousel or display, battery operated, variable speed.

I have started paining glassware.  I have an "artist's turnstyle" that has clamps to hold the glasses in place.  The base turns, but manually turning it leaves a lot to be desired in the quality area.  I thought about taking a Lazy Susan, adding rubber to the outer edge, and then place the Lazy Susan next to the turnstyle.  I could continuously spin the Lazy Susan which would in turn turn the turnstyle.  That might work for one or two glasses, but too many of them would cause callouses on my fingers, and the speed would vary.  My son suggested his K'nex motor and make a motorized small wheel to mount next to the carousel.  Sounds good, but does not have variable speed.      My husband wants to take a small motor and control the speed  with a foot pedal.  That would require me to concentrate on the speed, not necessarily the painting.  So I turn to the gadget makers for some suggestions or instructables.

What's the legit way to fix a crooked unicycle crank? Answered

I bought a unicycle off craigslist and I was riding it around. my foot slipped off the pedal, leading to a fairly nasty crash (I landed on my feet, the unicycle was the nasty part). when I picked it up, the crank was off by about ten degrees. I couldn't find any instructions on how to fix such an issue, so I just figured that if I hit it into that position I could just hit it back. I smacked it with a rubber mallet a bunch and it eventually made its way back to the right position. I'm now wondering why it was possible to just smack it to where it needed to be (seeing as I doubt a unicycle would have any pressure-fitted parts, especially since it's a sun unicycle AKA legit), and what the correct way (if this isn't the correct way) to fix it would have been. oh, and if it helps, the crank on the unicycle was also crooked before I hit it,  as in the inner surface of the crank wasn't parallel to the tire until I put it back. (sorry this is in the bikes channel, I guess the instructables sorting system isn't that diverse yet. I kid, I kid.)

Color changing stage lights?

I'd like to make a light that will accommodate 2 or three light bulbs/spotlights/floodlights so that one comes on, and ideally fades into the other. It would be used in haunted houses. I am pretty sure this is a simple build, but I'd appreciate direction or advice.  Or a full on Instructable. A simple setup with a switch (foot pedal?) that simply shuts off one color and turns on another would do.  A button that begins to fade one color out and another in would be better.  One that can be set to fade from one to another automatically at a predetermined interval would be awesome. Such a setup can be used to create a transformation effect as simple as Jekyll into Hyde or as elaborate as girl into gorilla. The reason I would prefer it to be automatic is so it can be "plug and play" with only one actor, and work even if it's a different actor each night. Probably something like this exists commercially, and A), I don't know what it is called B) I'm doing it for the Boy's and Girl's club, which has no budget, which means I'm paying for it, which means it needs to be as low cost as possible. C) If I can build it well and inexpensively, I'd like to play with variations on the theme.

How to ride DH safely

1. Always wear a helmet, wear body armor as well when needed (how much depends on course, and what you find to be suitable) at all times. 2. Look ahead of you. The faster you are going the further ahead you should look. 3. Stay focused and try not to concentrate or think while you are going at high speed, this tends to slow you down and/or cause accidents...practice alot and everything should come naturally with flow! - Before a run get a song or something that gets you "in the mood" in the back of your mind,and go for it - before you know it you'll be through the track/race no problem...you should all ready know the track turn for turn before doing this. 4. Make sure your tires have appropriate tread on them and are not cracking/damaged 5. Check your bike over in the parking lot before going up the lift. Ride it around and check the brakes and tire pressures. 6. Get enough sleep before riding and especially before racing. 7. Don't drink or get high before racing or riding (you can do it, and seen it done, but if you want to win or want to be safe...don't) 8. Stay relaxed and dialed in on the bike, be as relaxed as possible mentally before you start a race but be pumped physically at the same time. 9. Know the track as well as you can before racing it (the later steps will go into greater detail on how to do this). 10.Learn to 'pump through the ruff stuff'-pull up on the face and push down on the back side of bumps/rocks/landing trannys, etc... 11. Stay light on the back brake as much as you can and try to lock it as rarely as possible if at all...it may cause you to wash out. Only lock the brake on extremely sharp turns or to get into a turn if a cuttie won't be efficient enuff. 12. Try to go as fast as you can when you can-->PEDAL PEDAL PEDAL like a bat out of hell in the open or out of turns when/where ever you can. 13. Practice "cutties". 14. Buy the "Fundamentals" DVD available here on pinkbike.com or at most bike shops and study it...take notes if you have to. You will find how to do "cutties" on the DVD as well as many many more "fundamentals" for DH riding-----> BUY IT, you will be glad you did. 15.Off camber: make sure you weight your outside foot and stand the bike on the egde of the tire, that way it will stick 16. Rock gardens: the faster the better- you will bobble across the top and be on you way before you know it, rather than getting packed down and ending up with major arm pump. 17. Braking: only ever do real braking in straight lines, you can brake on corners but do it conservatively and only to slide around sharp turns better as it may cause you to wash out as mentioned above. The less you brake the faster you go and fast riding is a winning formula- think about that. 18. >>>Don't Crash It can have you out for the rest of the season and that can prevent you from winning races----obviously. Just dont ride like an idiot and attempt things that will probably end in you getting hurt. Ride within your limits! 19. (Words of Pro Down hiller Steve Peat from the "fundamentals" DVD mentioned above) "Stay as light as you can on the bike and pump through the back side of rocks or rough sections as a skateboarder pumps a vert ramp" to gain or maintain speed and momentum. 20. Trust your tires throughout the course. If you believe and have faith in your tires grip, chances are they will have grip fine. If you don't trust your tires and BELEIVE that they wont grip and you will probably fall, chances are they won't grip and as a result you will indeed fall. 21. Walk the track and look for new lines or which lines are best to take and are the fastest 22. Tuck when ever possible to conserve energy. Pedal hard in the open spots before the ruff stuff then tuck and pump and repeat. 23. True your wheels to increase your speed and pedalling efficiency 24. Don't use big fat mud bog tiresfor DH(i.e. 2.6"-3.0") EVER...unless your DH course happens to be a downhill mud swamp 25. Learn to brake with out losing traction , this helps in straight line braking before turns. 26.Push yourself in the warmups, (not stupidly) and give 95% of what your maximum was when you were pushing yourself, in the actual race. This way you wont fall, but you are still hauling a$$. 27.Practice shift points, it is very important to be in the right gear at the right time or youll be sucking wind trying to pedal a flat stretch in too high of a gear. On a fast stretch where you need to begin pedaling to maintain that speed, youll be spinning out. Know what gear to start in and what gear you need to be in at every point in the track. 28. If all else fails look fast across the finish line where everyones watching. 29.When learning, set your fork/and or shock harder than you would normally, this will teach you to use to body rather than relying upon the bike. 30. Try to pick memory markers for your self; tree stump, odd looking rock, etc... and break the course down in your head so you can become very quick overall. 31. Practice simple skills such as manuals (good for roots), Hops, roots/rocks) and of course cutties 32. Commit to berms, brake on a berm and it will end it tears, aim to "rail the berm" to do this - hit the berm at a speed that isnt too fast (this will cause you to slip up it) and not to slow (you will slip down and is slower duh) The ideal speed should carry you round as g forces will push you into the berm. 34.Take a couple of the "Learn to race" clinics offered before many of the sanctioned races. 35.Play with your set up, everything from seat angle, to brake postioning- it can all make a big difference. The more comfortable you are on the bike the faster youll go, the steepness can be different for each course(for instance) so tweak it a little each time but dont EVER change your entire setup before a race. 36.When walking the course, look back up at it. You will find new lines looking up rather then down. 37. While riding (including in the air) never squeeze the seat with your knees. This makes it impossible to flow smoothly, and makes you a ridged weight to be tossed around at the mercy of the trail. It may feel safer, but it will cause you to wreck and lose speed when you would not otherwise. In the air also, it you pinch your seat then you can not compress the lip and extend for landing. Also you can not whip and prepare for upcoming turns and bumps. The ONLY time that pinching your seat would be appropriate is when doing a suicide no hander which, if you can do it without loosing speed, is a cool way to entertain the crowd. 38.Learn to crash,it is an important skill to have that will save you alot of trouble in the long run. 39. Work your way up to the big stuff. Even if you are a good rider always warm up on an easier trail then go for the harder stuff you set out to conquer. Same for riding in general- dont go tackle the hardest trail on the mountain without first being able to do the easy ones---this may sound somewhat obvious but alot of people just cant get this bit of logic into their skulls without being told directly. 40. If the drop doesn't have a great tranny, hit it with more speed. this will cause you to have increased foreward momentum and less downward ( static ) momentum and make the landing smoother. let your bike go off the drop first. 41. If you are in the air ( off a jump drop or whatever... ) and your back end starts to dip too much, tap your back brake, this will cause the front end to dip forward. ( this is used all the time in Motocross) WARNING: Use this with caution and only when its a neccesity. 42. XC riding will make you faster. I always love watching the out of shape downhillers crossing the finish line and nearly having a hear attack. The more tired you are the more mistakes you make and the more likely you are to get hurt. Pedal! Then pedal more! 43. Train like a mofo. During my DH racing times I would spend the summer mornings doing 5-8 runs on local dh trails then dirt jumping and XC riding in the afternoon= Legs that were strong/fast as hell. Dont forget to train in the off season too. 44. Develop a training schedule not just for biking and racing but to keep in shape in general. The more you ride the better you will be. Like Ito was saying, do as much of each mountain biking discipline as possible with emphasis on Down hill. Cedric Gracia wins because he is a great all around rider as is Minaar. 45.Commit to the front end of your bike in corners. Watch Sam Hill, no-one does it better. NOTE: BEFORE DOING THIS, make sure you have practiced it and know how to do this technique at speed (Note is courtesy of Iceboy) 46. Don't pedal like a mad man out of the gate. Pedal, but let your bike gather speed and focus on keeping it. Racing comes down to one thing - exit speed , in particular your speed out of corners. Wait until you feel the flow before you start pushing it harder. If you pedal too hard from the start you'll flip in 60 seconds and get back on your bike a go harder to make up the time. Then you'll flip again. Speaking from experience on this one! It's all about being 'zen'. At least that's what all the dudes who keep beating me are telling me. Learn how to go as fast as you can through turns and sections to know your limits. 47. Make your riding FEEL slow when you are going fast! If you feel fast it's because the trail is catching up with you too quickly for you to process all the info in a comfortable time frame. Probably because you are too busy worrying about going fast and not feeling the flow. Look out, you are about to flip. It's that zen thing you're missing. 48. Practice having FLOW in all your riding, down hill (speed as well as flow), Dirt jumps (flow), XC(speed and flow), what ever (FLOW)... 49.Dont be intimidated by other riders, stay focused on what you have to do not what they are doing, if they crash pay atention to why, and try not to make the same mistake. 50. Learn to go over jumps at as high a speed as possible with out overshooting or losing speed by going too high. Jumps and learning to land them without thinking is a VERY beneficial skill to have... (if you want to stay low coming of jumps learn to soak up the lip...you will go just as far but you'll stay lower) 51. When doing a j-hop, bunny hop or going up the face of a jump don't forget to push into the ground and then come up to get more air. 53. The rougher the place you are riding the more ralaxed and flowy you should be trying to go . 54. Spend time at the track and just watch other riders(especially how they are going through the tricky sections that you are having trouble with), see what they are doing wrong and try to not make the same mistakes, also watch for where the speed spots of the section are. 55.Read Brian Lopes's & Lee McCormick's book " Mastering Mountain Biking Skills", this book covers everything you need to know in great detail from top to bottom, it is with out a doubt the most comprehensive guide for how to ride/race mountain bikes and how to handle and practice everything involved in riding. I HIGHLY RECCOMEND IT, and would say that it is the BIBLE for Mountain Biking! 56.Look where you want to go not at what you are trying to avoid. if you stare at the tree you are trying to go around instead of the trail around it you will more often than not hit the tree. 57. As mentioned previously-The faster you are going the further ahead you should look, always look at what lies further ahead when riding downhill AND avoid staring at your front wheel--staring at your front wheel will slow you down drastically and often will lead to crashing. 58.To re-inerate what Harding.Thomas was saying; do not focus on obstacles like stumps logs and rocks, because thats were you will go instead of where you want to go. In essence, keep an eye on where you want to go and you will go there. Do not look down at what your riding over, let your bike deal with the terrain, thats what its for. This is a very important tip to increasing speed and improving flow. 59. Before you go riding, I find that a simple 10 minute warm up on flat land and practicing tight turns and j-hops helps loosen you up and calms you down If you have any other tips, tell me! ill post them in the list.

Digital Music stand with timed page turning.

I really need to make a digital music stand.  Setting up multiple paper pages on a stand is extremely inconvenient.  It takes longer to set up the music than to play the song!  Plus, even with the arms extended on my music stand, it can only hold 4 pages max.  Some songs can be 10 pages or more. So here's what I'm thinking: A raspberry pi running a program to view .PDFs and a flat screen TV or monitor mounted to a music stand. W. Wayt Gibbs, here --> (http://spectrum.ieee.org/geek-life/hands-on/diy-handsfree-sheet-music) has already built the exact thing that I'm thinking of.  However, I'll be using this for drum music so my feet will be busy enough without having to use a foot pedal to turn the page (Maybe I'm not that coordinated. Definitely won't be chewing gum while playing!) So I'm wondering if anyone has any ideas about automatic page turning. My idea would be a .PDF viewer that can display 3 pages (so that the page turning doesn't have to be exact) and can be set to automatically turn the pages at a timed interval after i click start.  The problem with this is that each song will have a different timing.  Does anybody know of a program that can turn pages via a timer AND remember different timings for each file? I suppose I could just write the timing setting on the top of each .pdf and set it to that every time I open a file. Also, I'm not a computer programmer.  I have built a home theater pc which gave me a little knowledge.  But, when it comes to raspberry pi's I've never used one.  Is it powerful enough for what I'm proposing? Is that the route you would take? I'm also not sure what to use as an input device.  Maybe I'll just mount a percussion table to the drum rack somewhere and use a mouse on it. I'm open to any and all suggestions about every aspect of this idea. Thanks for any help or suggestions!

Make SF Meeting

This past Sunday I went to the Make SF meeting graciously hosted by Tech Shop in Menlo Park. I unfortunately do not have names and/or links to work relevant to the presenters, but I will try to give an overview of what I saw as best I can.The first presenter showed a musical interface he made with a laser pointer and a photocell that altered a track of music to correspond with the disturbance of the surface of the water. He told of how he embedded many such bowls in a table and had the laser pointers shining straight down into them from the ceiling so that it seemed as though the water itself was changing the music. He used it a party the previous weekend (side note: I never get invited to parties nearly as cool).Followed him was a man that created a device to interface with a computer as a USB HID. In short, it pretended to be a keyboard, mouse or joystick and then you could send it commands from a micro controller. He had his device installed in a model plane and based on accelerometer readings used it to control a flight simulator. Next there was a man from Google who showed the low-cost Arduino based glowing orb that he was working on based on the Arduino Orb Build Warden. This was presented as one possible solution to have widespread visual indication for monitoring the status of their ongoing projects. Presenter #4 promised not to have anything quite as high tech and passed around a copper bracelet made using copper wiring and traditional cold forge methods. He then spent the rest of the time talking about how he welded the ends of the bracelet with a tig welder made from a microwave much like this one. And even though he promised not to have anything technical to show, he went into the finer points of building your own microwave welder in regards to transformer modification and the importance of finding a reliable metal foot pedal to control the weld. Lastly, someone came from Shape Lock and demonstrated his "Ultra-High Molecular Weight Low Temperature Thermoplastic." Or in other words, you stick it in a pot of water heated to 160 degrees for a few minutes, take it out and bend it into any shape you want, let it harden for a few more minutes and you're good to go. You can use it to quickly and easily make all kinds of high-strength custom shapes and fasteners. It is actually very cool. However, remember, don't stick it in your mouth (or anywhere else!) because albeit non-toxic it will lock your jaw shut and good luck getting that back to 160 degrees. Oh... I should also mention that the meeting was organized and hosted by the legendary Andrew Milmoe.And that summarizes what I saw and heard.The next meeting will most likely be the first Sunday in March and you can get more info on the official Make SF site. Also, there will be a Make SF social gathering next Thursday at Mars Bar in San Francisco (7th and Brannan).It starts around 7 PM and there is rumored to be a special robotic guest attending. (if anyone has more info on any of the presenters please let me know)

The Dream Factory - Squid Labs and Instructables in Wired September 2005

This was Instructables' big debut. The author, Clive Thompson, came and hung out at Squid Labs for a couple of days, and later on we had a hilarious half-day photoshoot where the photographers couldn't remember Dan's name and had to keep calling him "wrench."Wired 13.09 The Dream Factoryby Clive ThompsonThey're already living that future in a small warehouse in Emeryville, California. It's the headquarters of Squid Labs, run by a gang of five MIT alums who by day create prototypes of new technologies for outside firms - and by night fabricate weird gizmos just for fun."Everything I own is basically one of a kind," says a cheery Saul Griffith, one of the cofounders, as he crouches on the floor of his dust-covered workshop, rooting through an enormous bucket of metal brackets and bolts. A tall, shaggy Australian, he's wearing ragged flip-flops and a pair of cargo pants so stained with oil and grime that I can't determine their original color. Dozens of his group's inventions lie scattered about: a Frisbee embedded with microchip-driven LEDs, a set of robots precision-cut from plastic, a bunch of helmet-mounted laser-and-GPS sensors designed to help firefighters locate one another in a blazing house.Today, Griffith is building a "hybrid electric bicycle" with a hidden battery compartment inside the bike's 4-foot-long, chopper-style front forks. To hold the forks in place, he spent the morning designing a bracket, then cut out a flat template for it on Squid Labs' laser cutter. Now, with that template as a guide, he hacks the shape out of quarter-inch steel, using a terrifyingly loud metal cutter. "I'm really into this 'tractor' aesthetic, getting everything to look like industrial machinery!" he hollers over the cutter's shrieks, while a 3-foot cone of orange sparks flies up and ricochets off his face.Every few minutes, Griffith pauses to snap a photo of his progress. When done, he'll write up a comprehensive guide on how to build his project. This, he argues, is the next crucial step in fab culture: getting hobbyists to carefully document their plans and share them online. Squid Labs is hoping to kick-start such sharing this fall when it launches Instructables.com - an open database of interesting projects and fab techniques, "kind of like a Wikipedia for making stuff," Griffith explains. If people want to build his electric hybrid chopper bicycle, they'll be able to download the CorelDraw design of the bracket and send it someplace like eMachineShop to have their own copy printed."We got inspired when we looked at all these guys who'd engineered these incredible, modded parts for their Harleys. They'd have amazing photos of them, but they'd never post the CAD image," Griffith says. "We were like, Why not go open source?"Later that day, I get a taste of how weirdly transformative this idea is. I'm hanging out with Dan Goldwater - another Squid Labs cofounder - and admiring one of his inventions. It's a pair of plastic gears that sit on a bike pedal and power a tiny generator. As you ride, you can run LED lights or a radio. I tell him I'd love to have a version of it myself. So a couple of Squid Labs guys go over to the laser cutter, pull up the design, and a few minutes later hand me exact copies of Goldwater's gears. Design once, print often. "Pretty cool, eh?" Goldwater grins."Griffith imagines that fab tools could produce new economic models for creators. Suppose a hobbyist made a cool plastic exterior for an MP3 player. Suppose she put the design online, and 700 people downloaded the file and had it printed at eMachineShop. "At what point," he asks, "would a manufacturer say, Hey, there's a market here - and offer to buy the design from her?""So, sure, soon we'll be able to build anything. But should we? "Let's say everyone suddenly can make their own hood ornaments. What if they actually do that? The real world would look like the Internet in 1996, when people started making their own Web sites." Griffith shudders. "Remember those hideous-looking psychedelic backgrounds and stupid animations? And blinking tags?""Rainbow dividers," Goldwater adds.It's a good point - and it makes me anxious about my guitar. Sure, it looked fine onscreen. But what if it turns out to be a monstrosity in my hands? Recalling my decision to use clear acrylic for the body, I break into a nervous sweat. It's going to look like something from a mid-'80s, big-hair heavy-metal band! What the hell was I thinking?Griffith interrupts my panic to announce that his chopper is ready. He wheels it onto the street, all five Squid Labbers in tow. Eric Wilhelm, a lanky designer, offers to be the test pilot. He straps on a helmet and mounts the seat. "Does it have brakes?" he asks."Sort of," Griffith says."It's amazing how often brakes are an afterthought," Wilhelm sighs. Then he hits the electric starter and peels off.
