Plexi-Project Help

Hello everyone, I've been looking at LED projects and devising my own for quite some time now. What i finally decided on was a Plexi glass tube containing a bonsai tree, with an LED array above to give it light. My plan for the LED array is squared away. and i have selected my tube (diameter of 8in). My hold up is the base and the roof of the tube. I want a fairly heavy material which can be machined to yield a snug fit. Does anyone one have any suggestions for the material or a possible source? if at all possible i would like this component to be less than 30$.

Painting and etching plexi glass? Answered

I'm working on a project to remove the broken plastic around my laptops screen section and replace it with two peices of plexiglass (Both front and back of the screen). with this i have a broken USB port that i can run power lines to two RED Leds to allow to light up an Etch on the plexiglass. but i really want to mask a small square in the middle then  paint he plexiglass black then etch in my logo. but i'm wondering if this is the best way to do it?  any suggestions??

Acrylic Heating Element - Questions for an electrician and acrylic expert

I'm trying to build a heating element suspended 1" from an aluminum surface, and 2" below what will be a piece of acrylic (hopefully up to 1/2" thick) suspended by aluminum covered 2x4's. I want to have a rheostat (I think that's what they're called) for variable control of the heating element. The width of the element is undetermined, although 1/2" is probably close and this may be of little relevance. The aluminum case itself is 21"x6" and 3" deep So far, I've harvested a coil of Nickel Chromium from a cheap space heater but in trying to create a suspended piece, I've done little but destroy my NiChrom. It was cool, sparks and all, but I'd like to get it right this time. I do not wish to use a torch or heat gun as the pieces are to be wide and the heat must be even over the width to create an aesthetic bend. I will post some photos of the pieces tomorrow. Feel free to throw your hat in on any questions you want to answer. Electric Questions: How much NiChrom. do I need to heat 1/2" acrylic to around 400 degrees (F) for malleabiity? What is the best way to mount or suspend the nichrom.? What is the appropriate method to attach NiChrome to the wiring? (My home made coil using 1/16" copper wiring as a cast was sound in theory, but practice yielded sagging of the strip when active, and eventually sparky explosions at the mounts, after which time this question came to mind.) What kind of Rheostat do I need? What kinds are there? What's the difference? Can I get away with using a 120v/600w Dimmer switch instead (please say 'yes')? Acrylic Questions: What is the ideal heat for bending thicker acrylics? Would a fan below the heating element help disperse the heat evenly over the acrylic, or mess up the dispersion? Can a heating element such as this create sufficient heat to 'weld' 2 pieces together? Is this even possible? Thanks. I'm sure I'll have more questions before you can answer those. Peace - Ian.Wms

LED Music Submerged in mineral oil. Answered

I have seen led music cubes and prisms here but is it at all possible that you could make one that does light up to music in a plexi glass cube but filled with mineral oil? If I were to do this of course itd have to be sealed water tight so nothing leaks, but is there anything else that might need to occur? Per say would I have to add a dye to the mineral oil to get a good luminosity effect or would it be shining bright without it?

What types of plastic glass do not go white when bent, and what is the best cement to join it to itself, please? Answered

When I am mid-way through a project I start thinking about the next one! I want to build a small-ish fish tank with a curved front. I envisage building a former of wood and 'wrapping' the plexi-glass round it to meet in the middle at the back. I will heat the plexi-glass gently so it can be bent but hopefully retain most of its thickness. What kinds of plexi-glass can withstand being bent and not turn colour? Also, what would be the strongest kind of cement to secure that join? I intend to reinforce that join by 'sandwiching' it with an additional piece of plexi-glass to give a greater surface area for the join, as water is incredibly heavy! FWIW I will also have much thicker plexi-glass at the bottom and top (top with access holes) with plenty of silicone around all edges. Many thanks for stopping by; I appreciate any thoughts you have. I will be posting this project as an 'ible to say thanks for the help.

Convert DC Light bar to AC

I'm trying to help out a friend. He's an animation student and he frequently has to use a light box while he's sketching. For those unfamiliar, he draws on a paper, and then puts another paper on top and traces it again, but with a slight change from the first. This process continues over and over until the animation is complete. In order to be able to trace, he's got a piece of white plexi (with a 90° bend in it) as his "table". He then places an off the shelf Energizer "Under Cabinet Light" under the plexi. This light has a fluorescent bulb and is powered by 8 AA batteries. Simple calculations means it's running on a 12V battery pack. Since he's often doing homework for 6 hours straight, the 8AA batteries become costly and the light dims over time. He was asking if I could hack the light to take AC power instead. I have an old wallward ac adapter that has these specs: Input: 120VAC 60Hz 30W Output: 12V @ 1.2A. I also took pictures of the circuit board I found inside the light. While I can't distinguish exactly what's on the board, I can pick out a capacitor, a transformer and some sort of regulator. I should've  got a quick schematic... from the looks my google searching, it's a simple fluorescent lamp circuit. Would it be as simple as stripping the ends of the AC adapter and soldering it to the positive and negative contacts on the light bar's circuit board? The adapter itself takes AC and makes it DC so it should work right? Another thing he is thinking of is having me swap out the tube for LED's. I'll just need an LED driver and I can use the same power supply I found in my junk box... it's just a question if the high powered LEDs would be bright enough. Surely if the tube is bright enough on fresh AA batteries, 3 high powered white LEDs would be brighter right? Also he's on a budget, so the AC/DC hack would essentially free for him!

I have something here that needs fixing ASAP

Well I have this Gigatube stereo that I am borrowing from a family member. That site in the link isn't very descriptive, 55 watts per main We have the higher end model (they made different models of the gigatube series at the time of purchase, btw that pocket too).Apparently from sitting up in our attic here not being used (yes it was in it's original box however), it appears to have developed a leak in the left sub's chamber. You can hear it when you turn it up anywhere past volume 10, but if I push on the plexi-glass, it stops making a vibrating sound, and it sounds fine from there.I tried tightening up the 6 screws around the plexiglass plate, underneath the front cosmetic plate (they're actually better designed than it looks from the picture, and produce some of the cleanest notes I've heard from a stereo of it's size). Anyways, that didn't fix things, and being they screw into plastic, I did not want to over tighten anything.Just today I took the screws out and the plate literally just fell off the speaker (if I didn't explain before, the plexi-glass seals around the front, allowing you to see the sub, but it bounces the bass back up the tube and it comes out there, from the looks of it, it's a 3rd type bandpass box). It looks like JVC glued these things on with something hard and flaky like superglue or something similar.So here I am now, and I'm wondering what I should use to glue it back on so it makes a TIGHT seal, I have a squeeze tube of this Clear silicone transparent adhesive sealant, would this be suitable? I found this tube after my father handed me a tube of caulking and I told him only a fool would use caulking on a sub, especially one of these pups.Sorry for the long, long, long post as usual, but I like to try to explain everything up front so I can get a answer sooner without having to wait for replies to "what is that" or lack of specifications, whatever.

iRobot Scholarship idea : Pool Cleaner

I've seen mods for the roombas before, where the robots are water sealed, and then the wheels are turned into propellers. My idea is that I could water proof the robot in plexi glass, or something, and then a net on it, to collect all the leaves, dead bugs, and other stuff that collects on the surface of a pool. normal pool cleaners only vacuum the floor of a pool, and it takes days for floating leaves and other grime to sink to the bottom. With a robot like this, I could just set it in the pool, and let it clean everything up. What's nice is, when company is coming over, it's embarrassing to have a dirty pool...this modification would allow you to quickly clean up your pool-even on short notice. Update (for some clarification): What I would want to do, is make a case for it, so that you can simply remove the wheels, and connect the propellers/steering device to where the wheels were, then just place the roomba in the watertight case, and it would be able to swim around and clean! Also, i'm working on some sketches of how it would work. I'll post those when they are done.

Well I'm getting tired again of my mac being extremely sluggish most of the time (the hd is pretty fragmented, too lazy to get my boot disk takes a few hours to defrag). A lot of the "sluggishness" is due in part to the rather extremely hot 1.2ghz ppc processor. I've tried putting xbox heatsinks on it (like seen in my instructable, search that shit) and I even made an addition of putting a fan ontop, but at the most I might have seen a reduction of 5C, but under load the fan made no difference. I know the internal fan can cool it down from like 78C (it gets hotter playing halo) to a nice 50C in a hurry at full speed. I haven't touched it though (wanting to hardwire it badly) because it has like 9 different wires for whatever reason (ground, positive and your sensor readout is all you should need right??). Anyone have at least some half assed idea of what I could throw together in a jumble?

Vandergraph generator

I am interested in building a small  vandergraph generator.  I am thinking this will certainly be no taller then 2ft and likely closer to 1ft.  I understand the general principal of how it works and this should be a good first voltage project that I should have everything I need for.  What has been holding me back for quite some time is that I could not come up with a decent belt for the inside.  But I read on the forums I think that leather is a good belt to use (or human skin).  This seems very odd to me and maybe I am missing something but is this really a good thing to use as a belt?  It would be nice because I could cut it as wide and long as I need and then sew it into a belt with some thread.  I happen to have some leather laying around from some crafting I have been working on.   Then as long as I am making this thread I was wondering what the best "tube" would be that the belt runs in.  I had considered making a plexi glass tube with hot glue to hold it together.  I think it could be cool to have a see through setup.  But I want this to work as well as I can get it.  So if a different material would work better I am open to suggestions. Also I will try my best to find my camera and post step by step photos once I know what the heck I am doing.

I would like to run on 12 volt simply because it gives it more power options for my needs, the one thing I'm kind of confused on is, Am I really gonna have to wire 1000 Resistors to make each LED 12v? Or is there a simpler method.. Also, power supply is an issue, I am not sure if I can just wire all the LEDs down to two wire for a regular 110-220V Input, 12v Output adapter.. Do I need an LED driver of some sort? Especially If I want to be able to dim. Building the Housing and stand shouldnt be an issue, Its more the electrical part where I am concerning myself with. I'm pretty mechanically inclined, I do automotive 12v as a profession and hobby, I'm just recently getting into "higher voltage" =D "I'M READY TO STICK A FORK IN A SOCKET!!" lol, can anybody give me any tips? details? or even how they would go about doing this? Any advice is better then no advice.. and any direction is better then starting lost, Thanks in advance! I Will start making an instructable soon once I get my supplies in (LED's, Mirror Plexi) Considering that where I have to start.

This is similar to my other topic, but I think it's worth a new topicmy company will be called electroni-C (pronounced electroni-see)I came up with cool marketing groups and product names, such as:electroni-CHIPSflavors: original (a bunch of generic boards that makes breadboarding easier, such as a 555 board, potentiometers that actually work with bread boards, a couple of mini powersupplies, jumpers, breadboard to aligator adapters, etcspicy: A lot of power stuff, like powersupplies, not just for breadboards, but for real finished projects, such as a circuit similar to mintyboost (but not the same, it'll be like a DIP package)optical (better name needs to be thought of) various LEDs, led drivers, optical sensors, and some logic to make everything useful. LED displays with integrated resistors for 5 volt (useful for less solder joints and less mess on a breadboard.caffine: motors, H-bridges, relays w/ saftey diode, servos, etc.Electroni-COOKIESNames are TBD, but here's what they are.

Challenge. Building a Lap Desktop. A keyboard, monitor, and speakers. Built into a Laptop case, plugs into a tower.

Scroll down for update I've been looking at new laptops. The ones I want are way to expensive. If I had a desk top I could get a lot more computer for a lot less money.   I have 2 old laptops. I would like to gut one of the laptop cases then install a new lcd monitor into the case which will plug into a desktop. I would like to do the same with the keyboard and the speakers. Whats the point? It won't be a lap top. This is correct. I don't want a lap top. I want a folding monitor speaker and keyboard that fits on my lap with cables that plug into a desktop that is sitting on the floor next to my chair.   I want to easily unplug my Lap Desktop, fold it up and then make it disappear. I want to sit in my comfy chair gaming talking to my wife while we both watch tv. I don't want a corner of my living room dedicated to a big old computer desk. The original idea was to use component parts of the laptop.  The monitor speakers, and keyboard. After doing some research I realize using the monitor won't work. That is ok. I will get a new one. Where to buy it? what to buy? I hope I can still use the laptop case and install the parts I want. and make it all work...  If this project seems like fun give  me a hand. Help me figure out the details. I will take the pictures and make an instruct able and credit who ever has helped me... I know I haven't got a clue and I have not found this product premaid and ready for purchase.... Update The Monitor I found what I need for my laptops lcd conversion to desktop monitor. I will purchase the R.RT6251 from njytouch on ebay. This essentially will allow me to use my old desktop lcd as a computer/tv monitor. I hope it works. I will also be converting the montitor into a touch screen. Njytouch has lots of good feedbadk and I have seen some great videos for their products on youtube. Theoretically I have the montior situation under control. The base. I have given up on the idea of using the original lap top base. I still want a clamshel design. Unfortunately I cannot use my laptops old keyboard. It worked fine for the lap top but like the original road block for the LCD at present I cannot find a easy solution to by pass the proprietary element. I was hoping for another miracle solution from njytouch. Don't think it will happen though. So for my contingency plan. A weighted plexiglass base I will mount my hinged lcd on with a shelf I will set my keyboard on. I have an old logitech g15 keyboard which would be awesome to use again. It sports several usb ports easy access for my peripherals.  When finished I will have a hinged lcd touchscreen mounted on a mounted on a weighted flat lap desk surface.. It will be a lap desk  with a clamshell design for easy storage that will all plug into a desk top computer.  Questions Is Plexi glass the best building material? What would you recommend. I would like it to be inexpensive and relatively light. This set up will be on my lap for hours at a time. So far I'm looking at about $150 for this building project and I don't own a desktop yet :) Are their any additions and improvements to this idea you guys can think of. I'm thinking monitors and speakers also... That may be going overboard though. .

How to make Flip Clock Numbers and build a "like"-counter around it?

Hey All So I've got this client, who's absolutely crazy about the "FLIKE" (A physical like counter.). But he can't have it for another couple of months, and he'd like it to be a little more custom... Long story short, I might end up making a similar product in a few weeks. it will probably consist out of 5 digits and if it's up to me (not sure what the client wants) I'd stuff them behind a long picture frame. Something like this but actually mechanical and not just a picture of it: So I started googling every hardware piece I needed and it turns out it's a huge pain to find Flip Clock Numbers / Flip Board Numbers... whatever you want to call them. (What's the right name btw?) You can't just buy these things, let alone in a custom size. So the idea is to build them myself. I found this on wikipedia, which gives a clue about the inside: So I'm figuring out what needs to go in it to make this work. (I'll end up making an instructable about it) The numbers themselves are going to be made out of vinyl stickers. You can easily buy those from ebay in about any size if you look for them. The stickers will be put on to plastic boards. But I'm not totally sure what kind I should get. They should be thin and must be able to stand up straight, yet "easy" to fold. I'll probably get them lasercut, but you should be able to cut them by hand as well. Currently I'm thinking about gluing small metal or carbon rods on the back of those letters. Although I'm not sure if that would be strong enough. Would it be enough to file one side of the rods to get a bigger contact surface? (What do you guys think?) I'm planning of putting the half letters in a drum of ABS or PLA. it should be shaped like this:  |--------| I'm thinking about 3D printing this. But no idea how it'll do... One side of the drum will be connected to a small stepper motor (5.625° with 1/64 reduction). I don't have real experience with stepper motors, but this resolution seems more than sufficient. The other side will be connected to a metal or plastic positioner. Each digit might end up with it's own "unit" so I can swap them separately if they'd break. I've got great experience with lasercut plexi, so I might use that because it's more accurate than wood and I might have some lying around. I was first thinking about 1 stepper motor and a set of gears. I decided not to do that in the end because I don't have good experience with making gears and I can never find the right sizes online. Also, it'll make everything way more complex. So each motor will have it's own controller connected to it. Those controllers would have to talk to an ATMega or something. (I'm planning on using an arduino to prototype, but then just swap the chip and make a stand-alone version without usb etc) The ATMega has to be connected to the internet of course to get the current number of likes, so I'd connect it to a raspberry pi via I²C. I'm not familiar with the GPIO pins on the pi so I figured this would be a save and convenient way to handle this. The ATMega is robust, and I love the Arduino bootloader. A sketch is written in no time, but I have no idea how to start writhing this code for the GPIO pins. So why the Raspberry Pi? First off, this thing might end up being wireless, and since a wifi module for the arduino costs as much as a Pi, I figured this would be easier. The plan is to make the pi run python script that could ask the number of likes from the facebook API. Once returned, it'll send +1 or +5 or +10 over I²C. The arduino shifts the numbers to the correct position and replies with the total number it's displaying (3012 for instance). The PI can then recheck if everything is in sync. As for the set up. Since we have Pi, we can put on a LAMP stack (I know, this is overkill, but it wouldn't hurt either). So for initial set-up, we'd connect the counter to ethernet, browse to it on a different computer via "http://counter.local". And we'd be presented with a web interface. You'll be able to set the URL of the page u want to get the likes from, set and reset the number that is displayed on the counter, and the WIFI settings. The WIFI settings can be saved in the wpa_supplicant.conf file and on reboot it'll automatically connect to this network. From now on the whole system is manageable over wifi via a html interface. For debugging I might enable ssh though. So I guess you've got the whole outline now. I'd like to get your feedback on this! And this for the mechanics, electronics, and software side of things!
