Someone posted a question asking about RFID tracking and didnt get a good response. I also have not found a simple answer to my question on Google. So I figured I'd re-ask the question in hopes of a better solution. In short, friends and I go disc golfing pretty regularly and losing discs is always stressful (obviously we are not pro's so the occasional disc will go into the wood or tall grass etc). I thought wouldnt it be great to stick a tracking device on these discs to help find them. RFID's being small enough to just stick them on and not sacrifice too much in performance to the disc, i figured that would be the best way to go. Question here: Is there a practical way to track rfid tags? basically just a device capable of telling you when the signal is getting hotter or colder. Thanks, DJ

Hi guys, I'm building an adaptable rover system which should be designed to go over rocky/muddy terrain (just imagine the basic farm environment). As i am doing this for an A level project, can you help me decide whether tracks or normal wheels would be better? Thanks!

I have a horrible problem with keeping cirtain objects of mine within my grasp. As such, I was wondering if there was anything I could put together or attain that may help me keep track of these things. I have no knowledge of these things, so forgive me if what ii'm asking for sounds far-fetched. I'm looking for something like a small thing little beacon that could be attached to something like a shoe or book that sends out a some form of radio waves on a constant frequency, that can be picked up by the receiver that essentially lets you know how close you are by the sound it makes, whether it be through beeps or noise level. I believe things like that are out there, but i'm wondering i';f I can do anything on a really really small level, like the size of a watch battery with a piece of adhiesive on the back. Any kind of help, even just to let me no that its not possible or whatever, would be great. Thanks in advance.

Does anyone know how to fix one? Are there specfic points that they like to break at? I got one a while ago because my old one died (heatstroke... melted things pretty bad), and it turns out, the new one is dead, too. I'm just not sure how. I'd like to try and fix it myself, especially since many electronics repair guys nowadays haven't even seen one. Of course, if you've read some of my posts, you know electricity is right behind jumping 100 feet in the air on my list of talents. It doesn't really seem to eat tapes or pinch them, and if I plug something into the phono in, I can hear it play through the attached speakers okay. The problem happens when I need to use the built in AM/FM radio (mono and stereo options!) or play a tape, at which point horrendous static happens. I think I can hear a motor spinning (maybe) when it's supposed to be playing a tape, but no useful sound comes out. The program selector also seems to be malfunctioning, and is stuck on program 4. I've got too much money sunk in my 8-track collection to make it economical to buy it all again; I'd rather get a machine working and transfer formats. I suppose I should have tested this machine before I bought it, but even if it never works again, I'm two very nice speakers and 200 feet of speaker wire ahead, so it's worth it to me. Another idea: is it possible to build one using cassette tape heads? That would be an interesting project, if a little unweildy.

I was thinking that it would be beneficial to be able to keep a list of other peoples Instructables that I have built. Sometimes I forget what all I have made and like to look back over them. Since I have built projects using existing Instructables I don't want to duplicate them by writing up my own of the same thing. It would be neat if there was a "I've built this" button or check box on each instructable, maybe in the comments section or something. Then not only could I look in my profile and see what I've made, but could look at an instructable and see who/or how many people have made it. As an author it would be cool to see that someone has successfully built something I came up with. Whatcha think?

First ever post after years of lurking. Searched but couldn't quite get the right answer. I'm trying to extend the battery of my GPS Live tracker. Currently I get 3, sometimes 2 days before the battery gets so low I must recover it. I saw where advertisers are selling 10 day batteries for up to $600. Just too much for me. The first picture is a completed model being sold on the internet. So I ordered the battery, ($58) and the charger ($45). Tomorrow morning I'll go find some connectors that match the charger and that I can use as a connector on the GPS. I'm going to go through the hacked battery case. I'll rig the the wires to match the holes then fill the empty case with hot glue to hold it in place. This is my big question: There are 3 electric tabs on the GPS. I have + and -. Can I just ignore the center tab? I will then run the wires through a hole I'll drill in the Hacked battery case. To a connector-connecting to battery. Any issues? The battery has a Built-in IC chip. I am assuming that is an IC chip on the old battery removed. I appreciate any input. Thank you.

I would like to have a timer for testing changes to pinewood derby cars. Need to have a trigger a the top of the track and one at the finish line. Could be stand alone with time display or output to a PC for capture of each run. Better still would be a second set of trips to give a split time 1/2 way down the track. Since this will be used for testing, it only needs to measure time on one track. Simple and cheap.

Question by David97 | last reply
I'm planning a stripboard POV kit to solder with learners over about 3 hours or so, and I have a problem designing the wiring for the LEDs. It's straightforward to use the required series resistors to wire the output pins of an ATMEGA like http://www.arduino.cc/en/Hacking/PinMapping to the anodes of 8 5mmx2mm rectangular leds like http://www.rapidonline.com/Electronic-Components/Kingbright-L-383IDT-5x2-5mm-H-i-Red-LED-Rectangular-56-0398 packed side by side onto 0.1 inch stripboard. However, I'm facing a puzzle when trying to wire the LEDs' cathodes together to ground. It's fairly easy for me myself to do this, just by free-soldering a couple of spare legs directly over the cathode tracks, or chaining loads of wires. However, I can't see myself guiding 45 people through this in a workshop without hassle and errors. Does anyone have a simple way to wire 8 'odd' stripboard tracks together to a ground track (the 'even' tracks have the anodes in them). To give a flavour of the solutions I'm considering, I'm looking into 0Ohm bussed resistor networks like http://www.interfacebus.com/resistor-network-schematic-bused-resistors-sip.html to wire theparallel tracks into a single ground track using a standard through-hole component with legs clipped off. However I'm having trouble sourcing anything like this, and I'm sure others have better ideas.

Hello all, could anyone give me some insight to how complex the process of designing a very small GPS tracker which could be used to track lets say a person, which can post its co-ords to map software which is custom programmed etc in realtime. Hypothetical scenario: 1) Tracking someone who is on the move outdoors, only has very small pockets to fit the thing in. 2) The device must send co-ords to mapping software on a computer every 10 seconds maybe. 3) Someone can view there position on the map software in instantly to understand their exact position. Also how expensive would the whole process cost to manufacturer roughly? Thanks in advance and sorry for the vagueness in my question

Question by Creativeman | last reply
Hello, I found here on https://www.instructables.com/ a lot of topics talking about gyroscope, accelrometer, & magnetometer sensors. How they work, the idea behind them, and how to make use of the data returned by different sensors. Then stays the ultimate problem of filtering the data and getting reliable data. Then there's an online algorithm for that written by PhD student which is a very good algorithm. It'll be used on PC side as I understood from some gurus that such algorithms will get the arduino to its knees. There're some sensors out there that you may cost you a little more but they have the option to get filtered data directly from the sensors. Then comes the question itself. Is it possible? Well that was my bachelor project to read how other people did it and redo it. Then I remember the first time I was searching for how to work with these sensors .. it was a mess. Then I made a decision to make this thing available for everyone to play with. So far I implemented "Arm Tracking" and based on the idea .. anything else will be possible actually. I wanted someone (or some people) to help or brainstorm with me how can we make it easier for anyone who wants to start with the sensors .. from writing arduino library to simplify this .. to the "Skeleton Tracking" thingy. Even if it'll only be explanation but I wanted it to be one big guide for everyone just to pay back those who helped me with other stuff they were good at. Even if the guide is about gathering resources in one big topic and linking them together. I hope I could deliver what I wanted to say properly :D Thanks in advance

I've copied the conversation here so we could remove the information from the original instructable's comments. I figure this would also be of some interest to other forum viewers who may have similar problems, or may be able to chip in. The long and short of it is, 92033 (Ed) has a refurbished laptop that takes literal hours to run a YouTube video on. I suspect that it's due to a bottleneck with his internet connection. Here's the conversation thus far: ---------------------------------------------------------------- 92033 (Ed): Thank you kindly for your prompt reply...appreciate it very much. I came across this site by accident in searching for something else and now I'm 'hooked' on it. :) So far I've read over 400 archived posts (whew)...as well as looking at the videos. The videos are somewhat of a problem because this new laptop only has 512 mg memory...LOOOOOng time to load. For example...to watch a SLOW 5-minute You Tube video takes 5-1/2 HOURS to load...keeps showing a couple words at a time...need to get two new memory chips to upgrade to 2gb. Thanks again...Take care. ---------------------------------------------------------------- eddems: I think you're basic download speed is killing ya, not the laptop. check you're speed at Internetfrog.com, if you see the link near the bottom for the old test, run it, I like it's graph of upload and download speed much better. ---------------------------------------------------------------- 92033: Thanks much. I'll check it out. I ordered a 1gb SDRAM Memory chip which just arrived yesterday. Hope this speeds things up a bit. ---------------------------------------------------------------- harley_rly: i hear u man, my computer is hopped up, but i live out in the sticks and have dialup...i only get 24kbps at most :( ---------------------------------------------------------------- 92033: Maybe there's hope for 'us' yet. :-) I phoned Tiger Direct to see cost of an upgrading memory chip to go from 512mg to 1-1/2gb. The guy I talked to suggested I get "PC TUNEUP 2.0" which bypasses the Windows Operating System (I'm using Windows XP Pro) and speeds up the system. I gave it a try and ordered the CD (cost $39.98 - $44.77 postpaid). It hasn't arrived yet but will let you know if it helps as he claims it will. He said that if I just ordered a 1gb memory chip my system wouldn't notice much improvement as it is, but this CD should do the trick. THEN...when I DO order the Memory chip(s) to get total of 2gb my system should zip through like a rocket with the CD just ordered. I'll let you know when I get the CD and about the results. Just hope I haven't thrown forty-five bucks to the wind. Thanks for the contact...appreciate hearing from you. TAKE CARE. ~ ED ---------------------------------------------------------------- Javin007: PC Tune-Up "bypasses the Windows Operating System?" This guy fed you a load of crap. (I work on computers for a living.) PC Tune-Up does nothing more than clean up registries, defragment harddrives (if your OS even needs it, some don't) and keeps drivers up to date (which you could do manually.) That guy's an idiot, or just a liar. Could be both. Unless you were buying PC Tuneup 2.0 from Tiger Direct, in which case we can add "sleazy salesman" to that. What are the specs of the laptop? Go to Start/Run and type in DXDIAG. This will give you a quick snapshot of the specs. Specifically, I'm curious as to the processor speed/type. For a 5 1/2 hour "load" you're more likely looking at network slowdown issues (although 512 megs for XP is WAYYYY too little. I HATE when they put PCs together like that). The RAM upgrade will show significant speed increases, but no improvement with YouTube videos or other downloads. I'm glad to see you are returning the CD. ---------------------------------------------------------------- 92033: Thanks much for your input...appreciate it very much. I checked the DXDIAG as you recommended. Here's the info on it: IBM ThinPad Laptop PC. Model # 23738TU. Intel Premium M 1.70GHZ. 512mb SDRAM Memory chip.Page File- 351mb used,513 mb available. Direct Version-Directx 9.00 (4.09.0000.0904). 512 mb SDRAM-Actual 212 Ram. AVAST Anti-Virus. MS Windows XP-PRO.. Dialup Speed-40kbps. PC2700 SDRAM 512mb Memory Chip installed. I ordered 1bb memory chip which arrived yesterday. Now I have to figure out HOW to remove the bottom of this laptop to install it...lotta small screws on it. :-) Oh, total memory shows 32mb. I don't know if this means much to you. I note your comment that the added RAM memory WONT (?) speed up loading YouTube videos? Is that correct? If so, why not? Thanks again. Take care. ~ ED ---------------------------------------------------------------- Javin007: :) At the risk of boring too many people, here's how memory in a PC works: You have two kinds of memory: RAM, and Hard Drive (technically there's three, as there's also onboard video RAM on video cards, but this is primarily used for 3D video game textures, so can be mostly ignored.) Your harddrive's read/write speed is determined by the type of harddrive it is (most are SATA now) and the rotation speed (most are 7200 RPM, though the specs for your system say yours is only 5400 RPM, but there are 10, 15, and even 20K rpm models out there that are exponentially more expensive.) No matter what, harddrive memory will always be degrees slower than RAM. RAM on the other hand is a small chunk of memory that is "temporary" memory, but very fast. Its speed is determined by the type of RAM (DDR2 being the current common one for notebooks, though DDR3 is available with some motherboards (you can ignore this, though, as you can only handle 2 gigs max of DDR with your system). The motherboard will determine the limits for the RAM that can be installed.) When running *ANYTHING* on your computer, and I mean ANYTHING, it must first be loaded into RAM to be accessed by the CPU. The computer doesn't directly access the harddrive. So this means when your operating system is loaded (Windows XP) the entirety of all running processes for the OS have to be loaded into RAM. Now, Microsoft claims that Windows XP only requires a minimum of 64 megs of RAM, but recommends 128 megs. I challenge you to find me a Windows XP system that only uses 128 megs out of the box. It's not atypical for an XP system to chew through all 512 megs of your RAM, leaving no RAM available for other applications. (Interestingly, the default setup for your laptop is only 256 megs of RAM, yet yours is reporting 512.) What happens when there's no RAM left? The system has to then start trading things into what is called "Virtual Memory." VM is nothing more than a file on the harddrive that will temporarily hold information that SHOULD be in RAM, so the RAM can load more info. For instance, say you have a process that's using RAM, but you want to watch your YouTube video. As the video is ready to play, the system will take the other process's data that's in RAM, write it to the harddrive, load your video into RAM in its place, play a portion of it, write the video to the harddrive, load the data for the process to RAM, let it run for a split second (so it doesn't lock up), write it back to the harddrive, load your video into RAM and play a short clip, etc. etc. etc. The result of low RAM on your system is that applications will open slowly (seconds or minutes, instead of instantly or a few seconds) and they will seem slow to respond, will stutter, etc. With enough RAM, your system can freely open as much as it needs into RAM, and ignore the virtual memory and all the slowdowns that it causes. Now, all of this being said, NO lack of RAM will cause a streaming video to take 5 1/2 hours to play. This is 100% going to be related to your downspeed. (Go to www.speedtest.net and post your results.) RAM slowdowns tend to be most noticeable when shutting down, or starting up your computer, apps will open a little more slowly, they will be slower to respond to button clicks, and video will be very choppy. Anything that is causing a YouTube video to take HOURS will be due to the system simply waiting to get the video in the first place. RAM wouldn't slow down the receiving of the video, but it would cause the video to play weird once it's downloaded. So, all this being said, here's the summary: Your system has a 1.7 Ghz processor, and your RAM is most likely 333 Mhz DDR. If you bump your memory up to a gig, you should see a pretty significant improvement in that your computer will, overall, just "feel" faster. It'll be more responsive, and working with large documents will be many, many times faster. This won't, however, affect your YouTube experience (unless you were getting jittery video often, not the same as "buffering" video.) If you see "buffering" for a long time, your internet connection is your bottleneck. A test on www.SpeedTest.net will likely confirm this. However, if you get decent numbers on SpeedTest, then we could have something more sinister going on, though I suspect you'll find your numbers well below the 1 mbps rate. This brings us to actually changing the RAM. I've been out of the PC hardware realm (professional programmer now) for a few years, and was unable to find a manual for your particular model. However, if memory serves, this image should be a fairly accurate representation of the underside of your system: http://www.javin-inc.com/temp/thinkpad.JPG Don't quote me, but I BELIEVE the red circle will indicate the only screw you will need to remove to access the RAM. There should also be a small clip holding the RAM in place that you'll want to pinch to get the RAM out, and make sure that the new RAM snaps into place. (Sometimes you'll have additional empty RAM beds, and you can just put your RAM in there and end up with 1.5 gigs, but I suspect you'll have two 256 gig chips in there.) ---------------------------------------------------------------- 92033: Phew. Thanks again for your most indepth educational lesson. I appreciate all your help more than you realize. I attempted to answer this last night, typing in more than twice the amount of text as your to me, then suddenly realized there was a glitch and I was on another page...lost it all into the ionisphere. :-( Rather than try to retype all I wrote, I shut 'r down and went to sleep.

I'll ATTEMP to try again later. So please don't reply yet as you need to read my discoveries in changing the RAM chip. Meanwhile, thanks again...take care. ~ ED ******************************************************************************* TRY #3...I'm Back :-) Your diagram showing where the RAM chip is located was right on. Thanks. Here's my DISCOVERY :-( The RAM chip installed was NOT a 512mg...but only a 256mg chip. The ads ans specs say it's a 512mg...NOT SO. I was lied to by either the manufacturer or refurbishing company who removed the original 512 chip and reinstalled a 256 chip. I was lied to by the Tiger Direct guy on the phone. There are NOT two chip slots...only one. So I now have a useless removed 256mb RAM chip. Replaced with the 1gb RAM chip I just installed. So instead of having 1-1/2 gb RAM, I only have 1gb. Here's the crux. To. go to 2gb RAM I'd need to buy a full 2gb RAM CHIP and discard the 1gb for which I just paid $39.99 ($45.00 with s/h). This means another output of almost a hundred dollars plus the $45.00 just wasted because they wont accept return once the sealed chip plastic was opened...even though I had no idea there was only ONE SLOT in this PC instead of TWO like the Tiger Guy said. Now...crux #2...this new 1gb RAM does nothing more to increase speed. I just watched a 2.01 MINUTE YouTube video which took a HALF HOUR to load, so I threw the money away for nothing, eh? There is no noticeable change except the 'speed' shows it now as 41.2 kbps instead of 40 kbps. Okay...now HOW do I get to speed this thing up to normal viewing in real time? I also saw an ad for 4bg RAM Gateway laptop with 120gb hard drive for $404.99 which is all suped-up with everything. I had to upgrade a LOT since I got this only four months ago...taking over a hundred hours to load it, like Internet Explorer 5 to 6 and then to 8 and now to 9. I'm using AVAST Anti-Virus, after trying for 23 hours to get ADVAR, then find out it didn't load because of problem on the servor's end. Added Firefox and upgraded twice. Loaded MS Protection but it created more problems so I deleted it...now with AVAST which I like. Soooo...I've literally spent over 200 hours to get this thng where it's at now, plus the wasted money for the upgraded RAM chip.and I still don't have increased speed. HOW do I get it? IF the processor has to be changed does this mean I have to gut the thing and install a new motherboard? If so, what kind of money cost are we talking here? I bought this four months ago as a refurbished unit only because I was able to get it on payments of only $25.00 a month. If I had to wait to get $400.00 cash I'd never have it. :-) Okay...that's it for the moment. Thanks much again for your help offering and detailed instructions...appreciate it more than you realize. Best Wishes And God's Blessings To You And Yours In Everything Always. Most Respectfully... ~ ED ---------------------------------------------------------------- Javin007: Well, let's start with the RAM. If you're running windows XP, you can assume all the extra processes (virus scanners, and whatnot) will be eating up about 512 megs of the RAM. First thing to do is check DXDIAG again (start/run) and verify that it's now reporting the correct amount of RAM. (Don't be surprised if it's like 9 hundred something megs or slightly more. It won't report 1024 or 1 gig.) This being said, that will leave you with the other 512 for your applications. This box won't be running the latest and greatest 3D games, but I suspect it was never intended to. If the heaviest hitter you'll have running is along the lines of photoshop, the 1 gig of RAM you have now should be plenty sufficient. I wouldn't worry about getting 2 gigs. Not for this rig, anyway. Also, Avast is a great (and free) virus protection, every bit as good as Symantec's Norton, so good choice there. If your youtube videos are choking out, we need to start by verifying that it's an actual speed throttling problem. Go to www.SpeedTest.net and run the speed test. Come back with the results.

I'm a college student in charge of building a float for our homecoming parade. The theme for the float is mario kart, and the design has a track with moving carts going around a track. What is the best way to make a track with powered cars moving around the track? A generator with household voltage will be used to power the track/cars. I know I will need to transform from 120V AC to something else, probably 24V DC from what I have read so far. I don't know much about electricity and the other forces at play in designing such a track, so any detailed information or reference material would be appreciated. I have attached two sketches of the float design, one of which is to scale. Any suggestions would be helpful. Diagrams would be very helpful as well.

Hi all- I'm looking for a way to construct a tripod that can be set to rotate, tracking an object (basically would want it to be able to remain facing a certain object as it moves back and forth. I basically need to have a camcorder that can be recording, and remained aimed at the subject without a cameraman). Any ideas?

My daughter is going into high school and has had her scientific calculator stolen for three years in a row at school. These are pricey, running from $30-$40 each. Besides that, all the other things in her pencil bag, like compasses, triangles, pens, mechanical pencils. Frankly, I'm sick of my daughter not being prepared for class and spending money for the reprobates to just steal it. Is there any way to tag her calculator economically to track it down?

Britain's ubiquitous CCTV video surveillance network has nothing on Japan's Orwellian nightmare in the making. One of the country's top electronics firms, NEC, has just announced a new plasma display fitted with a tiny camera that can accurately identify a person's age and sex in order to target them with specific advertisements.... Here is the LINK to the original site I came across.

Hi folks looking to build a tracking solar panel for North and South directions. I have a few drawings made up but im stuck for the maths side of things as I have a size limit I need to stick to in. I need the panel to move by 15° towards north and towards south. So a 30° movement in total. What I have in mind if an arch where the panel will sit on which can be moved with a single piston placed on the South end of the panel. This is to contract and expand to move 15° up and 15° down. My size limit is the panel must not exceed 200mm or 20cm in real money when at its maximum positions. I have assumed a 2 meter long panel (or array of panels in a frame) So because of this im a bit unsure about how to tackle the maths side of things to work out the arch's profile to meet this criteria. Anyone got any words of wisdom? The 200mm limit is the max UK law allows me to play around with the panels maximum position.

I'm expecting a package from lootcrate, the tracking number they provided me with says "foreign receipt" and doesn't show any activity since then. Edit: The parcel is coming from the US, and I live in Mexico

I'm about to start back to school and I want to be able to find my bike when it gets stolen. (I am operating under the assumption that it WILL get stolen.) I'd like to outfit the bike with some sort of tracking device, something that will be somewhat easy to hide and not cost me hundreds of dollars. I am a tech newbie but I have friends that can help me with anything complicated, so be specific if you have an idea and I'll do my best to figure it out. Thanks!
