waterproofing a CD spindle

Hi all, I've been working on a variation of an existing instructable and I thought I'd asked this q before, but can't find it. SOooo here goes; I need suggestions on sealing a cd spindle into its plastic cover? I've managed to do it with about 4 sticks of hot glue and several burnt knuckle but  there must be an easier way? cheers, flashj

hard drive spindle motor?

I have a hard drive spindle motor that i have taken off of my old 10 gb Hard drive. I was wondering if i would be able to run this motor off of a pc molex connector. i have extended the wire from the molex plug and touched them to the leads on the motor, but all it does is jerk. I can't get it to stay spinning. Do you have to have a controller mechanism of some sort or what? I have tried the red wire and ground and the yellow wire and ground. They both don't seem to work. Would make a difference if i solder the wire onto the motor? I was just thinking this would make a great fan or something along that order.

How does a spindle sander oscillate? Answered

I'm wanting to cobble together a spindle sander using the guts of a hand drill. Mounting it is pretty trivial, but it would be very cool if I could make it oscillate vertically as well. Unfortunately, I don't have a spindle sander to take apart so I can see how it operates. Can anyone tell me what mechanism moves the spindle up and down? Does it use the same motor that rotates the spindle, or is there a secondary actuator involved?

Hard drive spindle motor repurposing

I am in the materials-gathering phase of a planned project to build a handheld stabilizer system for use with my dSLR camera when I shoot video (for an example of what that kind of is and does, look http://freeflysystems.com/products/movi/m10/).  I have a number of older or decommissioned hard drives and optical drives laying around and wondered if I couldn't repurpose the motors from them to use as the axis motors for my stabilizer.  The SimpleBGC board from Alexmos is built to drive brushless DC motors such as the spindle motors found in hard drives.  My questions would be if this would work and whether they would be "strong" enough to turn and hold the camera carriage according to the controller's signals.

I'm looking to turn a 1/4 in square ended spindle with a shaft which contains a ratchet mechanism. The ratchet mechanism will be contained in a shaft at 90 degrees to the spindle so as to allow a turning of the spindle through a fraction of a revolution before returning to start. The ratchet shaft would be permanently and securely fixed (bolted?) to the spindle and allow a reasonable amount of torque.

Need help on identifying big BLDC motor from 5.25 HDD (hallsensors?)

Hi! I have a very nice 5.25 HDD spindle motor with (obviosly) built-in hallsensors (or probably other kind of sensors?). I tried already to find a datasheet, but no success. The 3 spindle coil connectors are easy to identify, but I have real trouble to find out how to connect the hall sensors that are built in. I tried already to put 5 V DC from my arduino to the red/black connectors, then measured several combinations on the remaining 6 connectors which I believe are the hall-sensors. But the signals coming back is not 0 or 5V like a hallsensor should do. I measure slight voltages going up and down when turning the spindle by hand, for some combinations the current is alternating between -200 mV and +200mV. It looks more like a sinuswave for me, but not from the spindle coils. It delivers only a signal when I connect 5V to the red/black connectors. Unfortunately I can't open the spindle, dont want do damage it. The original driving circuit is missing, only housing, platters and spindle is left. Can anybody help to identify or how to find out about the sensors (6 pins + 1 black + 1 red). I also added 10k pull-up resistors, but no on/off effect when turning the spindle. The HDD is a FUJITSU M2266SA, the spindle is manufactured by Matsushita but google does not return anything useful on the part number(s) DIL-58B 3  or  B90L-1415-0021A.  Any help to get this baby running is highly appreciated!

Advice needed on nearly complete instructable

Sorry this is a bit long, but there is an actual question at the end, honest! Every morning at work I walk past a table at the end of our mailboxes that people put give away items on. Its usually a catalog of some form but for a long time now there's been a stack of empty CD spindles and a sign beside them that reads "free to good home." I could have taken them and sorted the mountain of CDs in my office or used them for small parts bins, but to make it areally Good use of empty CD spindles I had to ask myself "IS there an instructable in this?" There are some good ideas for using CDs and a few for the spindles, but at the moment what interests me is hydroponics. So using CD spindles or more exactly the plastic covers they come with I built the basic part of this excellent instructable: http://alturl.com/oa2qt    and I learned a lot of stuff about water pressure and such and once I had built the 2liter bottle method described above I decided to try sealing one of the CD cases and use it for the water container at the bottom of the stack. That took about 4 sticks of hot glue and a couple of burnt knuckles to get a good seal. Turns out there's holes in the center spindle too but I didn't notice them till I had hot glued the container closed. Also ignore the bit of blue air hose inside the container, I was up way too late and flipped the CD spindle 'right side up' which caused me to attach the air hose to the wrong outlet and basically made it useless. I thought I'd need a lot more water in the system than I do so I chose to use a 100ct CD spindle instead of the 50 ct spindles you see on top. (Thanks to all for the ideas on how I could have done it easier!) So far this part of the project was just overlaying the ideas in the excellent instructable above onto the materials at hand. So what I ended up with is an air pump from a fish tank pumping air into the bottom chamber. (the clear hose in center of picture.) This builds up enough pressure to push water thru the blue hose and up to the top CD spindle. I've cut holes the diameter of the air hose into the base of the spindle and this lets water slowly trickle into the Perlite growth medium. When the water reaches the bottom it goes out similar holes in the clear plastic CD cover and starts to pool up a bit to start the process all over again. There is just enough lip on the lid and the bottom of the next spindle to keep it from spilling down the side before this happens. It helps to use the same brand CD spindle all the way up. The clever part of this instructable is that each CD spindle easily stacks in place and you can remove it or change the order without having to dig up or harm the other plants. The base is very stable with several ounces of water in it and I'd imagine you could put 4 of these in a stack and happily swap plants in and out all summer long. The height of the stack depends on how strong your air pump is. I tested two different ones and both were capable of lifting water over 4 feet  up the air hose. Caveat: I haven't actually grown any plants in this yet, so your mileage may vary. Using the stack of CDs for use as apartment planters or sprouting medium would have satisfied the original curiosity for what to do with all those left over CD cases, but in absence of glowing blue LEDs or CO2 lasers I thought Hydroponics would be a great way to sex up the overall idea. I imagine you could use spanish moss or bedding in place of the Perlite, or even soil if you used a coffee filter to cover the holes till you were ready to stick a seedling thru it. This Instructable isn't quite finished as presented. There's a small problem. As you can see in the photo there's a half height (25ct) CD spindle between the water container and the stack of planting modules. Remember that hole I mentioned in the end of the CD spindle? I closed that with a bit of plastic and hot glue, but it made me wonder, COULD I put some sort of check valve here to allow unused water to trickle back into the holding tank YET not lose the hard fought air pressure that's pushing the water to the top of the column in the first place? Since I'm re-using all this old aquarium tech I thought I'd try one of those tiny check valves that keep water from backwashing into the air pump when its off. I'm not sure if it will work in this application or even how much air pressure it will tolerate. This will require some disassembly of the CD hydroponics tower and I thought I'd ask here for suggestions before heating up the glue gun again. So what do you guys think? This has been a lot of fun to think about and I can't wait to bring the media guy  around into my office to see how I've re-purposed the spindles. Just this one last step away…. cheers, flashj

does someone want to make a tobacco shredder?

Hi Guys, one of my new hobbies is going to be growing tobacco, I know how to grow and cure it but what I need is a decent method to shred it. I can slice it with a knife but the strands turn out too big for hand rolling, there are commercial products around which can shred tobacco but the best around for the home grower which doesnt cost the earth only cuts to about 1.5mm now what I need is 0.5mm. I was thinking of was to combine 2 ideas, this one which seems to be based on the old victorian tobacco shredders http://www.howtogrowtobacco.com/forum/cpg14x/albums/userpics/10155/normal_b_processequipcutter.JPG with this one, which uses a nice method of keeping the tobacco compressed and moviing it slowly with out chopping your fingers off. http://lh5.ggpht.com/_2A4aHZ23tp4/S5P-L7KOxaI/AAAAAAAABnA/KqWk0ZoLf90/s640/loaded%20shredder%201%202010_03050006.JPG the above used a handle which turns a theaded spindle which pushs the block along by a fraction, you then use a knife to take a slice off the end. now there is an automated one someone made in new zealand which looks awesome, this also uses a thread but they have put a ratchet spanner on the spindle so it automatically moves it along. So does anyone fancy this as a project? it would have to be easy to make, made from materials which are easy to come by for normal people, it must be cheap and it must be able to produce a really fine cut at least 0.5mm good enough for hand rolling tobacco.

Dirtmobile?

So I got this awesome idea to make a trike with a snowmobile donor. Use the snowmobiles motor and track for the rear "wheel", and a gokart style front end, with 2 wheels, spindles, maybe suspension, etc.  Nothing too big, maybe 400cc or less. 2 stroke of course =D. I am proficient in fabricating, welding, and have a full auto shop worth of tools, so the actual construction shouldn't be a problem. However, I need to know some things about the snowmobile drive train.  Would the track itself work on dirt, light mud, light puddles (2-4 inches deep), and maybe some sand? If not, are there any tracks available for such terrain? Do most snow mobiles have the engine mounted infront of seat, below, or behind? This thing looks wicked cool in my mind.  OH, heres a good way to put it. Like a snowbike (Dirt bike with tracks in back), with two front wheels. Or a honda ATC with tracks flipped rear/front.

Knex HD Circular Saw

This Circular Saw that you see here is one of the many knex things i've been working on, but have not shown you guys because of not really wanting to post anything in the past... however long it was. A little more about this saw is: it is the first Circular Saw on this site if i'm not wrong. If this saw was real; it would have a Gasoline engine for power and instead of a motor being in the old motor compartment, it would have a massive spindle brake so that it stopped spinning faster. Some things that is saw lacks is the fuel tank, the blade guard, and an on/off switch. I would have loved to add those things to it, but I ran out of some parts that were vital to their creation. A quick fact about the blade; The blade's diameter is 8 7/8" or roughly 225mm. The blade's thickness is about 7/10" or 17.8mm thereabouts. Overall, I think that it turned out alright but could have been much better. Still something to look at every now and then I suppose. It was fun to make, and was something to do.

Hey Makers and Breakers, Tinkerers and... uh, Thinkerers! Tyler here, from the Makers Local 256 hackerspace in Huntsville, Alabama! I just wanted to share some of the projects and ideas we toyed around with on our monthly build night for July. Our theme was Sugru, thanks to some kind gifts from Carley and the rest of the folks at Instructables; you guys rock! We had a few different projects that were worked on, so I'll start with the ones with Instructables attached first! My project was to modify an AppleTV remote so that it would stop sliding between the cushions of the couch, but decided to allow it to stand up on its own as well. The mod was quick and simple and is described in my Instructable here. Another member grabbed a couple of those spinny whirlygig handcopter toys and set out to combine them into a single, more powerful, machine! Those of you who knit know the annoyance of losing stitches when transporting your works in progress. DeathRogue decided that enough was enough and fashioned some knitting needle endcaps out of Sugru! We also had other little projects, including adding a Sugru kickstand to a Galaxy Note 2 for watching Netflix, building a wooden spindle using Sugru for the kickwheel, creating rubber Sugru feet for a Raspberry Pi case, and even practicing the ancient Japanese art of breaking and mending pottery pieces: Kintsugi!

Ingenuity Needed: Cutting records with quality.

It's lengthy, sorry, but it's worth it! Let me preference this with, I know this topic has surfaced before. Most of the forums and pages are filled with broken links to information, sold out products, and are all around rather worthless to return to. I'm posting this in hopes it stays a useful reference point. For  a few years now, I have been looking at cutting disks playable on a record player. I found an 'ible a while ago (the original one I bookmarked has been removed) that showed how to make an needle assembly. It demonstrated making a record engraver by putting a staple through the center of a speaker. This tool kind-of worked, but had some quality issues, as well as speed. When you push to engrave the audio, you slow the table. Less pressure, less quality, more quality, less speed. The other issue I ran in to was keeping the groove tight enough to hold more than 20 seconds. I'd like to construct a device that will cut CDs in to records with a good bit of accuracy, and give a second life to mis-burned disks (as well as some ancient unsupported linux disks...driver disks...early Windows builds...AOL disks...you get the idea) Putting the proper spindle on a properly geared motor should resolve the speed issue on cutting. Having the cutting arm on a servo should resolve the length issue, my only quandary is quality. ~~~~~ So, the point of this post, and the thing I'd like to have some input on is, How do I construct a cutting needle, that will offer some quality. I should refine that a little more - something that is going to transfer bass well. ~~~~~ I was not eager to puncture a speaker, so I modified the original plans. I placed the staple in a layer of plastic, and glued this to the speaker. The plastic gathered more of the vibration, and funneled it to the cutting head more accurately. This did work relatively well, but I feel with a few extra minds, this process can be made better. If this project ever sees the light of day, I'll make an 'ible, and cite any assistance. -Spence

Needle valve on the cheap?

I need a needle valve or similar to adjust some pressure with more or less precision. Problems I am facing with commercial solutions at the moment: Needs to withstand about 300psi max pressure, must survive contionous exposure to concentrated ammonia vapour. I already wasted too much money on stainless steel valves claiming to be chemical proof and capable of 6000psi only to find out they use seals that turn to goo in the ammonia vapour and fail. And since the stuff is not really healthy, not easy to get, I would prefer something safer. Real problem is also that the thing should be able to allow for good flow rates when opened fully. Modes of operation: During the active cycle ammonia vapour needs to pass through an opening as big as possible while after that the flow must be shut off. The reverse cycle needs to be adjustable from closed to fully open with great detail to control the flow rate. Current ways to compensate: With a ball valves and extra piping I could seperate the two cycles so I won't have to bother with tiny openings but I would prefer to use only a single connection. With a bypass around the needle valve this could be accomplished better but still looks ugly. Materials out of the question: Copper, brass, normal seals based on rubber, nitrile or similar. Questions: I know fully sealed in.line valves exist for LPG system and similar. Are any of these magnetic valves available for the use with ammonia? And if so: Can they be operated with a neodymium magnet instead of the coil? Even stainless steel valves rated for chemical use and high pressure fail quickly on the seals. Is there anything available that does not use soft seals but for example aluminium instead? Thinking spray pump here... One way ball valve systems like used in simple spray pumps are a great thing. With some aluminium tubing I was able to make a simple valve that with some more attention to detail might even work. But of course there no other way of moving the ball then to use a magnet and with sufficient back pressure even neodymium ones fail to get the ball in the open position and keep it there. Now getting this combine with a needle... If, instead of the ball, a magnet in a teflon shell is used on a spindle I could spin a magnet around the outside to turn the valve with great precision. Has anyone already designed such a thing or would I have to start from scratch here?

have i got 1 good driver or 3 bad ones

Hi all, nice to be here I have just finished building my first cnc router and about to start actually doing something with it, during my build I somehow managed to blow up 2 grbl boards and 6 drivers, hey note to myself, don't connect voltages when tired late at night also I have a problem, I think, thanks to YouTube I found how to set the voltage using the trimmer pots on the driver boards, I set all 4 drivers initially to 0.75 volt and it all works and tests fine, apart from having to buy 2 more driver boards when the trim pots fell off that is apart from one of the stepper drivers powers one motor (Y axis) and when it finishes working it goes absolutely solid locked up and sounds like it is groaning, the other 3 are firm but not locked up I tried increasing the voltage on the 3 looser stepper motors to 1.0 volt and it didn't seem to make a lot of difference, but to get the solid stepper driver down to the same stiffness I have had to drop the voltage down to 0.4 volt and it did stop groaning and loosened a bit I swapped over the motors, same result, moved the driver to another spot on the grbl board exactly the same effect on a different motor, so it looks to me like it is the DRV8825 driver board is this a case of I have 1 bad board and 3 good boards? or 1 good board and 3 bad boards ? any help would be more than welcome info on my cnc build and components below basically the cnc has a bed of 900mm x 900mm and is pure self build made up of parts found laying around my workshop, rails bearings lead screws etc, and I added in a new Arduino uno (of which I am novice) and a new GRBL board and ended up using DRV8825 drivers, stepper motors are used (eBay) 4 x identical minebea 23LM-C343-14V wired from 6 wire down to 4 wire with pairs being red & yellow and pair 2 being blue & orange, which I believe is correct LINK TO STEPPER MOTOR SPEC SHEET please correct me if I have made a mistake I have used links to set all drivers to 1/32 micro stepping, also set the mm rate so it is exact at 500mm travel, and set max speed at a sensible 400mm per minute as I am not really expecting supersonic speed and all is nice and quiet, nothing straining I have paired 2 of the stepper motors via the grbl to drive the X axis and used the clone spare on the GRBL to make that work, which it does marvellous The CNC structure does need strengthening up as mostly built on ply at the moment, but everything works as expected, the spindle is a nice almost new RotaZip high speed tool that I bought new about 4 years ago and only used it on one job so keeping stuff does come in handy even if wifey says it doesn't Look forward to sharing info on here as I learn more
