How to harden a 'rubber bone'? Answered

A few weeks ago I was digging a new garden and I uncovered an old beef rib bone buried next to a rusty tin can. I presume one of my dogs put them there several years ago. The bone had developed a nice patina, infused with a reddish-brown color, most likely from the rusty can. It would work perfectly as scales (handles) for an old hunting knife of mine if I could flatten it out somewhat.  Remembering an old trick from my youth, I have been soaking it in white vinegar and it has softened nicely without losing the patina. From my past experience I know it will re-harden if I allow it to dry out, but it will be more porous and brittle. My thought was to dry it then coat it liberally with super glue or to soak it in a clear acrylic paint for several days to fill the pores. I am looking for any ideas or suggestions that will help me in this project, whether they be ways to make my ideas better or something entirely different. Thanks.

could someone cut a piece of plastic for me?

I have a mp4 player i got a few days ago, but i find that the original cover plastic has a sort of paint that, when combined with the glare of ambient sunlight, makes it totally impossible to use the player outside. not only that, but the plastic on the front got a really nasty scratch on it when i was cutting open the box. There isnt a screen protector on the player. if i gave the dimensions of the plastic part thats scratched (gold-silvery part of the player) could someone cut a new piece for me, be it laser cut, cnc milled, or by hand, whatever. all i ask is that its clear plastic. for those who would like to know the plastic is 1mm thick. if it could be done for free it would be so greatly appreciated.

How can I make footswitch controllable stage lighting?

I'm looking to make something that sort of combines both of these, but i'm really hesitant about diving into something like this as I don't want to shock myself or someone else haha. This seems like it'd be easy enough to build yourself, but I can't say for sure.  I'd like to be able to control 4-6 colored lightbulb fixtures with 4 separate footswitches.  I build guitar effects pedals, though I can't read schematics, so I have knowledge of building enclosures and swtich setups.  So if it's basically just a power on/off switch to the light would that blow out the bulb quickly?  would it have to be another way of switching it on/off?  Would it have to be a specific type of bulb?  I was thinking about having an enclosure with 4 on/off footswitches to control the lights, and then 2 momentary switches that will only turn on if the switch is pressed down.  I want the power to be grounded, the enclosure would be 4-6 switches with 4-6 outlets for the lights and then one cable for the main power.  Any help on this would be greatly appreciated.  Thanks. - Matt

D-Flip Flop and Clock Alarm

Hey there! I'm trying to hook up one Set Pin of a 74LS74 Double D-Flip Flop to the alarm of my clock. I've already desoldered the annoying buzzer thats been there before and am now measuring the voltage provided to the buzzer. Unfortunately the circuit only provides around 0.1-0.7V (crescendo alert) with each beep, which doesn't seem to be enough to raise the Set Pin to HIGH (0.8V min. I think). So I guess I'm supposed to use some kind of transistor now. Just to make sure I'm asking you guys. Also, if I want to run the clock from a 5V DC wall wart instead of the original 1.5V battery, I suppose the only thing I need to add are some resistors in series. Would that be correct or would there be anything else needed to ensure the clock takes no damage? Would be really nice if someone could help me out with this! Best regards, Philipp

y should you use a pump in small hydroponics??? not needed in most cases?

Most small setups are keeped in the house where you stay. so a small sprayer is all you need if you keep your plants on top of a plasic sheet with water and clay pebels. a good layer of clay ball socked in water with the plants on top is not going to cause root rot. you can use plant pots or rockwool cubes and dosen`t mater if you don`t spray them everyday.. a heaing pad under the hole thing is also a good idea . the heat will cover a larger area by gently heating the water also this way is perfect for seedling just cover with a clear plastic sheet. humidity from the heating pad under the sheet will act as a heated propergater.   here is some music to listen to while you read

How to build a 2D pen plotter for 24"x36" paper?

My dad's pretty attached to his 30 year old pen plotter since it will draw on 24"x36" paper(he used to be a draftsman), but he wants a new computer. I need to find out if it would be easier to build one from scratch rather than try to find drivers? I'm thinking on something related to the drawbot? He probably won't let me hack the parts from the old one to make a new one, which might make life easier. Unfortunately, I have programming skills limited to "Hello world". Design constraints: 24" wide paper width (adjustable?) 36" or more length, would be awesome if it was able to use paper rolls (Might need to batch the drawing in sections for this) USB would help Must support multiple passes for colored inks, or else upgrade to 4 pen system Thanks! -GreatPanda

555 working backwards?

Hey, so i wired up my 555, with a trigger button, and because i only had small resistors at the time, I used one to give a really quick period. however when i put in a brand new 800 KOhm resistor (that should have raised the period to 8 seconds) instead of lengthening the period it put a time limit on the trigger. so now i have an output that stays high for a faction of a second and then the chip can't be re-triggered for 8 seconds. i know people don't have an encyclopedic knowledge of 555, but does anyone more experienced have any ideas why this might have happened. thanks in advance.

So i am trying to make a geiger counter (if you don't know what it it) and i'm kinda getting somewhere, but there is a problem. i need to get more sound out of the bulb i'm ionizing, i am ionizing it with very high frequency and low voltage (very low) and i connected it to some speakers that i have (they run on they'r own battery so i need only signal) but its very quite and i need to make it more... louder. So how do i do it? i'm kinda guessing i have to connect the input wire on parallel or in series with some batteries to the bulb so the high freq voltage or current would get up, and i also will put a potentiometer to get it to the stage before ionization so.... yeah thats all......thnx for all answers.

Specs for Blue lights: DC Forward Voltage (VF): 3.2 Vdc ~ 4.0 Vdc DC Forward Current (IF): Typ 650mA Specs for Red lights: DC Forward Voltage (VF): 2.0 ~ 2.8 Vdc DC Forward Current (IF): Typ 650mA I know a lot of things on the internet call for resistors but for this project, resistors would give off far too much heat. I know that an LED driver can be used in place of the resistors, but I don't know anything about voltage or amps. I have found a few 200W LED drivers that connect to an outlet and convert the power to a 24V DC, which is usable by LED's. I just don't know if that's all I have to do: connect the driver to the LEDs in a parallel circuit. Actually, I don't know how to find the Constant Current Module that I need at all. PLEASE HELP ME!

Removing someone else's comments!

I'm sure this must be covered somewhere but I can't figure out how to get rid of someone's inappropriate comments on my Instructable.  Any help is appreciated.  I went to the comment, clicked flag.  Marked as inappropriate.  Does it just take a few days? I don't want my project to be a platform for a loudmouth that isn't even speaking about the project.

What exactly are patches?

I've noticed a lot of people thanking each other for sending patches or something like that and I also noticed that there is a 'send patch' option on my profile. I'm new to this site so I don't really get it. Neither could I find any information about this topic on the site.

What is wrong with the picture editing textboxes!!!??? Answered

Nowadays, when working on an instructable, I get cryptic error messages when I put just a little more text than one line in a text box. This is extremely irritating!, and serves no purpose! The box then does not show up... I like to decide myself how to to do the layout of my instructable, and not be limited by someone elses' standards. This limitation degrades the site and should be removed immediately!

And I was having the most fantastic day......

Really I was, I got into work, and had no real tasks to accomplish since my mentor was home sick and his boss was sick. Except she was so sick she asked me to do her job. So I got to spend 9 hours escorting 4 PE's all over to different locations. Climbing on roofs, crawling through mechanical rooms. digging things up, getting wet and dirty, all while trying to maintain a professional appearance.  I loved it!  I can't even express how much I love going to work, being an engineer is awesome. But then I got home to discover a microburst had hit our neighborhood. And was filled with anticipatory dread as I noticed the 65 foot oak in front of my house was no longer visible over the neighbors roof line. Well, the pictures below speak for themselves, there was only one way this thing could fall and NOT hit something, and it fell just that way. And if I hadn't been home late from work, my much loved truck would have been right under the trunk.

Why don't people modify MOT's for high voltage? Answered

Why don't people modify MOT's for high voltage? I just did I left about 3 layers of primary windings, removed the middle coil and the shunts put it back together then submerged it in oil, I also removes a couple of layers of the secondary windings to get rid of the resin so the oil can get in. It worked amazingly I don't understand why people don't do it.

Computer PSU's and Peltier elements?

Hey, I have 2 158W Peltier elements, that I would like to mount to some CPU-heatsinks, and power with an old 400W PSU. Can I "just do that"? There seams to be some caveats with how these units draw power AFAIK. Also, does anyone have any experience with how much heat displacement is needed to not just ending up frying the unit? Any suggestions on what heatsink to pair them with, and how strong a resistor to put on them? I want to use them at the maximum power I can get them to run with continuously for up to 2 hours. I have way too limited experience with electronics, and only a week to build my project, so I kind of have to go with the simplest approach here :(

while loged in, when i click to view an instructable it says it cant find me as a user

Hello, I recently discovered that I could change what I thought was my display name on instructables. (the one that you only have one chance to do) But instead discovered that it is not only the display name that has being changed but my login username as well. Although a bit disappointed i figured "no harm done" but lately after some time with the new username i keep bumping into weird situations. While logged in and active when I click on an instructable to view i get a popup on the bottom of the page saying "Sorry, we can't find that account, or your password didn't match. Please try again!" if I navigate back and choose a different instructable I can view it will all steps on one page as I have it configured. Then if I try to again view the intructable that gives me the error I once again cant. This seems to remedy itself if usually when I'm logged out due to inactivity and then log back in. On other occasions I find myself unable to log in getting the same error as above. Deleting the cookies does not help with this. I am able to log in from the same access point through my mobile but not my computer. User/pass saved on both devices as to eliminate getting the login credentials wrong. I'm thinking this might be because of the unusual characters in my display/username? I was surprised that such characters are allowed for usernames, this also was a point that got be thinking that its the display name that I'm changing not the username (as for example in flickr). Please advice! p.s. after writing this I pressed "Preview Topic" and if I hadn't copied the text when after I noticed that the page was acting up I would have lost all of it. This happened several times while writing an instructable. I went to save or navigate to a different step and the page doesent load and if I press back I loose everything if I haven't got it in the clipboard. Again do you thing that this is related to the weird characters in the usename? p.p.s. I had to change browsers from firefox to chrome in order to be able to post this
