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.

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.

There is a quite concerning trend happening with mostly Chinese sellers on Ebay.Before you panik: Ebay is happy to help in these cases and will refund you if the seller does not cooperate.Here is how the "scam" works:You buy an item that is of least some value.For my cases it was always items above the $50US mark.In the listing you will spot a hint that for some festivities, specail day in the calendar or just for good luck you will receive an additional and free gift with your purchase.Usually these gifts are of little to no use and included in the actual item delivery as they are tiny.Now some dodgy seller realised that with the free shipping options available in China it is quite easy to provide tracking information for free as well.As a result you GIFT is used to provide the Ebay tracking for the item you bought.Some days after ordering yu wil then find a small evelop in your letterbox...No obvious connections to ANY order you made ANYWHERE on the envelop so you open it.Then you find the meaningless gift and a crappy note informing you that your actual item was sent using a different service.A non-working tracking number for services like track17 is provided as well.Only hint you find it is Ebay related is the seller name at the bottom of the note.Checking your purchase history in Ebay will then show your item has been delivered and that you shall leave feedback now.The seller won't respond to any messages with your concerns.Here is how the solution works:Contact the seller and clearly state that Ebay selling rules have been violated by providing false tracking information for the item you bought.Demand a full refund based on that breach.If no response within 24 hours contact Ebay.This contacting however is now quite complicated due to the fact that the seller fooled Ebay into thinking you already have your item.There are two ways that still work.a) Call them or click the button to be called.State the breach, seller name and item number in question.b) Use the resolution center.For this you need to click a bit through the options to see all you transactions and from there select the item in question.A) will be the fastest way, B) works fine too if you prefer all in writing instead of a call.The whole issue can be as meaningless as your item arriving a day or two later.But if the trend catches on then it is no problem for a seller to close business and do so with one big win before closing doors.It is never just a single "mistake" of this kind, it is either a test to see how trusting people are to be fooled later or a direct attempt to scam you.Being a clear violation of Ebay's selling policies for once the buyer is actually secure here, just out of pocket from the day paid till the refund arrives.The refund usually is issued within 3 days after the seller did not respond the correct way to EBAY.Once you informed Ebay the whole case will also be added to your resolution center where you can see updates and have the option to react to what the seller answers.You can also leave negative feedback for such transactions and the seller won't be allowed to give you a negative feedback for it.Just be careful not to click on any of the stars!You CAN leave feedback without any star rating in any category listed!

Hi, I'm not sure where to start, my understanding of the components and tech are minimal at best. I know what I want to achieve and I believe it is a possible project. I'm looking for any advice even if it exists outside of my current knowledge. Essentially the idea is similar to this "lost child locator" product- http://tinyurl.com/pd8goy7 or these t-shirts- http://tinyurl.com/mkm5b8k What I'm struggling with is how to carry out the concept without involving a smart phone. I'm looking for a larger range than 15M, multiple devices to respond to one-another, and for the watch to act as both transmitter and receiver. A simple LED indication is sufficient, no sound or vibration are necessary. I think BLE is the proper signal to work with but I don't want to involve smart phones at all. Compactness is a major plus, but ultimately I would settle for a mint tin or puck sized device. Everything would need to run on a small battery as well. The practical application of this project is for times when you're in a large crowd and you are looking for your group. If you had a watch tuned to your group, you could more easily track each other down if you knew someone was close.

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?

Question by Forcegame24
Hi guys I hope this is ok to ask about as I have followed Instructables for ages but not used the forum part before. I have a bit of experience of arduino projects and doing basic sketches for them but nothing as ambitious as this so am seeking a bit of advice if possible. I'd like to be able to have a droid/robot's head that can rotate to focus on the direction of a sound, then if it sees a person once looking in the direction it heard the sound, to then roughly track them (move its head) with a camera. I'm fine with motorisation and that side of things, but I'm not sure if this sort of fairly elaborate setup would be possible with an arduino or would need something more powerful like a rasp pi? I'd imagine that I would need an array of several mics as inputs around the bot in a 'circle', and code that can estimate the direction by means of the signal strength from the mics when it hears a noise. I think this might be something I can manage to do, but then it'd need a suitable camera and a means of tracking and I've no idea how the tracking side of things would work with that. I'd be grateful for any pointers to get me going thanks. It's not something I could do without help but hopefully doing it bit by bit and with some advice I'd be able to do this, as I would really love to make it work! Many thanks! Jim

Hi All, First of all I'll describe the project I'm working on Then I'll Highlight my probelm 1) Description: - Now There's a boat travelling on a river. There's a satellite Receiver on the boat so passengers can watch T.V. While Travelling. The river is not straight and there're situations where the boat needs to turn 180 degrees. What I was trying to do is to have a gyro or compass beside the Satellite Receiver and detect when the satellite is not pointing to the right direction (due to the boat going on cureves & turning 180 degrees) and undo that rotations so I can keep the Satellite receiver pointing to the right direction ('cause if not so then they'll lose signal and No T.V any more :() 2) The Probelm: - I tried to use Gyro ArduImu V3 but the readings aren't helping much .. some times it's wrong and the yaw drifts a lot :( - I tried to use compass but it's not tilt compensated .. meaning that if the compass is n't on horizontal position it'll get different readings! and when they pass below some high Power Electrical lines the compass Gets crazy :( I hope you got the description & the probelm. Is there anyway else to do it? Or if there's any recommendations I'll be grateful :) Thanks in advance anyways kind Regards --- Ahmed

Meant to update on this here a while back. For nearly two years now I've been developing the prototype for a solar energy device makeable from scrap and recycled materials, using very basic tools and skills. It's now working, details available here: http://solarflower.blogspot.com/ Facebook group here. This has been possible largely due to the awesome help and support I received through this site. Currently I'm back in New Zealand, preparing the first free workshop on the device's construction and use, taking place the three weekends after Easter at the Tui community, Golden Bay. Then back to Europe for the summer and tour this thing around. Animated tutorials will be available at www.solarflower.org as soon as I find a spare second to do them and finish the website.

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.

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.
