What lubricant to refill a fridge compressor with?

Hey all, I just grabbed a compressor from a fridge that had been badly mangled by a bulldozer at a demolition site, planning to make a vacuum pump or airbrush compressor (or both!) Trouble is, I thought the liquid it contained was leftover refrigerant, and drained it all out. I didn't really have a choice, as leftover freon was gassing out of the compressor (thought it had lost pressure, but there was still a little in the compressor) and it was sputtering the oil everywhere. I held it upside down while carrying it home, and when I got it here, it was apparently empty. Then I found out that what I poured out wasn't liquid freon, but actually vital oil that keeps it alive. The compressor runs fine, but I only tried it for a few seconds for fear of destruction. I have many lubricants here, motor oil, 2-stroke oil, bike chain oil, etc. If I'm to dump an oil into my compressor, any ideas on which is the best call, and roughly how much should it take?

DIY AUX unit with steering wheel controls

On my previous car, I hacked together an aux input with two CD-ROM plugs as described in many places on the Internet (here's one). I was really happy with it, and fully intend to do the same on my new (?) second-hand car, which also has CD-changer support, but no AUX. (Neither car had a CD changer installed, because I couldn't be bothered). The new car has steering wheel controls though, and I thought this could be a nice upgrade, but I'm really not sure how to do it. The pin-out diagrams for the CD changer plug (which I stole from here) for the CN702 12 pin connector shows lines 9 and 10 as TX signal lines. Since there are track (and disc) up and down buttons on the radio, I assume this is how the commands get through to the CD changer. And the phone obviously has support for headsets with track skip buttons. So the stars seem to align. Except for the details.  First, a normal audio cable only has three wires and one with headset controls have four: Ground, left, right and comms. I think I can connect the following pins on the 12 pin connector to ground: 6, 7 and 9 and then 1, 2 and 10 get connected to the correct wires. Is this correct? Second, I have no idea if the actual signals sent to TX for a CD changer bear any resemblance to what the phone expects from a headset. Does anyone know? I can probably hack a test using a bread board. I think. Third: I really only dabble in these things. Did I miss anything really important?

IR trip wire with discreet components

I am in need of help and I am going insane with this. Question is about a simple circuit with IR sensor/tripwire part and 555 timer which would keep the alarm buzzer on for thee seconds. No fancy stuff like arduino or relay or anything like that just LEDs, resistors, transistors, 555 timer and a buzzer. I got the IR sensor part to work and the timer part to work, but when I try to combine them everything goes haywire and nothing works. I have IR photo transistor TOPS-030 as the IR sensor. I am really starting to lose my mind with this and it has been three years since I started doing this project. I got diagnosed with undefined neurological disease (probably MS-disease) which has slowed my down even more. I worked on the circuit every now and then not every night during the past three years =) I know this circuit is simple and it can be put together in a brief moment the thing that is driving me crazy is the fact that when I got something working then everything goes haywire. Doing very basic beginner instructable describing this circuit would be very helpful even to others not just me. It would also keep the knowledge of using discreet logic up in these micro controller days.

iRobot Create Submission: Automatic Field Chalker/Painter

Hello fellow Instructablites,As both an athlete and innovator, I am constantly looking for fun, easy, and creative ways to circumvent mundane tasks or activities. One specific task I've noticed many a time is chalking or spray painting line dimensions onto a playing field or court. For some sports, such as baseball and driveway basketball, the playing fields are chalked instead of painted. The lines are time and again washed away by a rain storm and it must be done over. With soccer fields, the painting must be done once a season, plus the second coat for playoffs. Basketball courts must be taped once a season as well.What compels me so much to create such a bot is the degree of simplicity that can be achieved for these tasks. There is so much complexity in laying out a correct set of lines and arcs. From circular three point arcs to proper dimensions of a volleyball court, there is plenty of room for human mistakes. A fully automatic Roomba would be able to both speed up and eliminate incorrect, and potentially gerrymandered, field lines. They will be pre-programmed on the bot and selected for what particular field it is designated to line.I am convinced that all of these types of tasks can be implemented into an "iRobot Create" to lessen the burden and hassle of the aforementioned activities. My brother Steve and I have developed this idea and fully believe it can be implemented well within out intellectual boundaries.After reading some of the comments we've received, we are now taking into consideration some new ideas. In-route Calibration. We aim to implement an accelerometer to keep the dead reckoning honest. Chalking repository. Instead of heaving all the chalk around in one huge battery draining load, we are considering using chalk/paint stations to refill the coating supply. Hopefully this will keep power usage at a minimum. Tank treads. These will probably enhance the fielder chalker/painter in every way, since it will be used outdoors.Thank you for taking the time to read our entry!Nick and Steve

Solder sucker?

Hello all.  I had a question about desoldering.  First thing is that I have desoldering wick.  I found out I was using it wrong.  I melted the solder and then placed the end of the wick in the melted solder.  But I watched a youtube video and according to that I should place the wick on the solder and then heat up the wick and solder as one.  But this still has not been working very well for me.  The wick is over a year old and I was wondering if this could be a problem.  But my other question is how well do those spring loaded solder suckers work?  I was thinking about perhaps ordering one off of e-bay.  Yes I know I might find one in a good hardware store but I have some paypal money I could use.  In case you do not know what I am talking about....it is the spring loaded suckers where you cock it, put it next to the melted solder and then press a button and it forms a vacuum and sucks up the solder into it.  I think I can pick one up for a few bucks off-line, so if you people say they work well then I will give it a shot. Also in case you want to know what I am working on.  This would be used for salvaging parts of of circuit boards.  Like right now I am trying to salvage a few capacitors and also a couple of flyback transformers from crt computer monitors.  Also tomorrow I am tearing apart a broken water cooler to see if there is anything I can take out of there. I have also being having a problem getting solder to melt in the first place.  But that probably just has something to do with the 2 soldering irons I am using and I am trying my best to figure it all out.  I know my way around computers as far as building and repairing them.  But soldering and desoldering is something I really want to learn to be able to further my computer repair skills.  Sometimes it would save so much money being able to solder and desolder myself.  Especially those darn ac ports that are soldered right onto the boards sometimes. I have not actually made anything from this site yet.  But this is a wonderful site and after cruzing the forums here I am pretty sure I will get some good replies.  Ok I will stop babbling and I look forward to your replies.

Troubleshooting Christmas Mini-Light Strings

I searched Instructables to be certain I am not covering something someone else has already done, but found nothing.  Here is an excellent article on troubleshooting a bad string of Christmas mini-lights. (I do not know the author and am not connected to him in any way.)  I know of three occurrences of non-working light strings from this year's celebrations. In the first case, the woman who owns the Christmas tree simply bought a new string of lights and hung the new lights over the old string attached at the factory to her synthetic tree. I did not see her tree and cannot say what the cause of the malfunction was. In the second occurrence we put up a synthetic tree with two strings of factory installed lights, one for the bottom half of the tree and one for the top half of the tree. The string on the top half worked some of the time, but then would go out. Typically one suspects a bad bulb. That is also the general suggestion made in the very fine article I linked above. However, that proved not to be the problem. Rather, the problem was the very cheap electrical plug. I cut the plug from the string so I could open it and determine exactly where and how it failed in order to satisfy my own curiosity. Installing a new male plug solved the problem. In the third case, my daughter had a string near the top of her tree that was "out," but not completely at the top. I had limited tools and resources, but plugging the bad string into a different molded female plug brought it back to life. The moral of the story is that while a bad bulb is a frequent source of problems, the molded male and female plugs on these inexpensive light strings are often held together only by a lick and a promise, and fail easily. Giving the molded plugs a hard look is much easier and faster than removing and testing bulb after bulb. The first photo shows an extension cord with molded plugs from three strings plugged into the extension cord. The second photo shows the bad male plug on our tree, and I am using my multi-meter to test for continuity between the brass plug blade and the load end of one of the tiny fuses inside the plug. That part tests "good." The other fuse tested "good," too. In the third photo I inserted a straight pin into the wire and tested for a circuit from the brass blades to the wire. Both sides failed this test.  A multi-meter can easily test what I needed to find this problem. I would have needed to strip away some insulation from the wire or stick a straight pin through the wire to obtain a reading with my multi-meter. But, by this time I had bought a hum tester with a high and a low range for checking different voltage ranges on an AC circuit. It led me to know the plug was the problem.

Custom Painted Nerf Guns (Looking for Offers)

Hello!  I'm JonnyBGood, and I'm looking to accumulate some offers for my custom painted Nerf guns. I don't plan on going as far as commissions, I just want to see if there's any interest in my work for the right price. As of right now I'm mainly checking the market, before fully investing in making more custom Nerf guns. When making an offer, please send me it in a PM and make sure to consider that I've spent a minimal of five hours of painting. Also consider the cost of the blaster and the time required to make modifications. In my state, the minimal wage is around 8$ so I will ignore any offer that has me literally working for free. I hope that this works out and I receive a lot of reasonable offers so I can start painting, and then I will definitely get back to everyone who has sent me an offer.  Thanks for checking out my latest endeavor, and I hope my received feedback allows this to be successful!  JonnyBGood

Contest prize stuck in customs

I was recently shipped the Photography Tips and Tricks contest prize,, it got stuck in customs in India. I've received a few prizes in the past without any problem but it probably got stuck this time because of its high value. After a discussion with the FedEx folks, the total amount including custom duty(around 25-30%) will be around 34% of the total prize value, even after I told them I'm an individual and this is a contest prize. I understand that the contest rules state that I have to pay all custom duties and any other cost incurred. Any authors here who have faced any problems with customs and if this is the expected custom duty in India(seems a tad too high)? Any declaration(such as gift or prizes) which can help reduce the duty amount?

Monster battery pack for pedalboard

Hi! first of all happy being here in such a full and interesting community. Since some time i have an idea fix, i would like to play guitar in the street, not for the sake of money but for pure entertainment. Following that intention i´m being gathering all equipment i need for that purpose. I was asking myself the question about power source for all that stuff. Actually i can make it easy, since i already bought roland cube street, that runs on 6 AA batteries. BUT, i guess nobody here likes easy things. Therefore here is my project: using acoustic guitar with 4 effects and the amp running on the SAME external battery pack. short description of the project : 4s4p battery pack for a total of 14,8V and 12 000 Mah more or less.. will depend on cells themselves. Theoretically it will mean 10 hours or continuous run with all of equipment. of course there will be step down converter and other bells and whistles that i will be happy to share once i start doing it. Questions mainly are : I know that Boss pedals have center negative connection, What the hell does it mean? please someone help with this cause im getting mad. Is it just inverting the leeds? positive one going to the sleeve and negative/ground to the pin? OR it means that the pin has to be  minus 9V? This is the main question as i dont want to burn 200 euros pedals second and less important one: i will mostly go with NCR18650GA units. And will arrange a balanced pack. As the charging rate is 1A rough it takes 3,5 hours to charge. If the total capacity is 12 amp as i'm planning will it be neccessary to wait 12 hours to charge it or 4s4p scheme will still need 3,5 hours to charge all of cells at the charge rate of 1A, can i also charge it at faster rate as cells state that discharge rate is10A and so i coud use up to 10A charger? Or maybe the smart chargers identify by themselves the best charge rate? thank you in advance please know it's my first project of the kind :D

Recording digitally with an analog camcorder

I recently came into possession of a mid-eighties Newvicon analog camcorder. It has RCA outputs for the video and audio (mono), and I'd like to record the output from this camcorder as digital. The idea I had initially was to use something like a Flip video camera (in order to keep it portable), but then I realized that the Flip doesn't have an RCA input... in fact, nothing I know of has an RCA input, unless I wanted to plug it into a computer or a DVD recorder, which negates the simplicity of it recording to a video file that can be dragged and dropped onto my desktop. The reason for wanting to salvage this camcorder and use it instead of just using the Flip is because the video quality is incredibly "eighties" - the color is slightly askew, and the sensitivity to light means that moving the camera suddenly causes ghosting, which, to me, is desirable for the look i'm going for. Personally, I find it fun and interesting to use old things like this instead of the new stuff. The only drawback is the simplicity (or lack thereof) in being able to post things immediately in this digital YouTube age. I'd like to keep it portable. I'd like to keep it simple. Any ideas on a camcorder, or even a "digital go between" that would record onto an SD card or USB drive? Does anything like this exist? If not, I'd like something like an SD card go between, as I have a 32 GB SDHC that would work great for this kind of project. This is the same model camera - the video outputs are located on a proprietary PSU, which isn't a problem for me to carry around, or have plugged into an extension cord.

I did that and got some info on what the sketch should look like on Youtube but I am struggling to get the printer fully functioned. This project is a little more than what I thought it would be. I tested the boards but they seem ok, again, Youtube help here but now I am at a loss. I mannaged to get the stepper motors to work but I am struggling with the famouse endstops and how to home the axis's. If you think I am way less than a beginner you are right. These things make my head spin. Is there any one that can share his marlin sketch configuration, that is working, with me. I am tired of this now and just want the printer to work. Any help will be much appreciated Many thanks

Orange pi's 3.3V on board regulator

Hi everyone, I've set up a mediacenter with openelec on my orange pi PC. I've put a large heatsink on cup and rams and a small 5V 0.15Ah cooling fan. With two switches I am able to switch it on and off and choose between 5V or 3.3V alimentations from the GPIO. The 3.3v is intended to spin that fan not at full speed to reduce noise while watching film or listening to music with the mediacenter. I left the PC all the night open downloading torrent, and the morning later the fan wasn't spinning anymore. I powered off the system and used a day later. The fan were at that moment working. So my question are: Is it better to put an external voltage regulator (lm317)? Anyone can explain what happened? As I recently discovered that with zener diodes we are able to clamp the voltage to a specific value (if putted in the "opposite" direction, I guess), I was thinking if it were possible to use one of them in this case.

Searching within a category

I am searching through all the crochet instructables. Every time I click on one I want to Favorite and I go back to the list of projects, it brings me back to almost the beginning of the list instead of where I left off. This is very frustrating. Is there any way it can be fixed? Thank you,
