Tell us about yourself!
I do have a couple more due to minimum order...if you send me your address I'll mail one to you. Unfortunately I was not able to get my project to work...it's possible my bootleg arduino is junk but I don't have time to troubleshoot at the moment. If you get yours going pls let me know and I'll give mine another go...thanks, Art.
I'm still in the game on this project...it's been 3 years but haven't had much time to spend on hobby stuff. I was able to recently do a cad design for the signal conditioning circuitry and had a board made up....might be another few weeks before I can fire this thing up for testing.
Hello...in the text you mentioned that you increased the value of the 0.047uf caps for better sensitivity...can you tell me the range you experimented with....was it 0.047 to 0.1 or did you have to go higher?
Eco Friendly Metal Detector - Arduino
Hi....I watched a couple of vids concerning the installation of Tuftex roof panels and it's recommended to use their foam closure strips which, as claimed, provide support and weather protection. Have you noticed any adverse effects by not using them in your build?
Sure no prob. Just FYI, although I installed a Bluetooth module in the fencing target I ran out of time to complete the remote buzzer portion of the project and never picked it up again....this was a Christmas gift for my daughter and I was already running 30 days late! I think if I were to install this feature I would do away with the RF portion and simply hard wire a power and control line from the weapon to the target...fencers are used to wires anyway!

If you ordered the updated display this code should work fine. The new displays have an inverter-driver now so I had to rebuild the character table to invert the logic from the original code. If you see funny characters it means the table will probably have to be updated for your particular display. Good luck!

Very nice STL.....is this for one transmit-receive pair?
Hi.....I guess the original link must have expired but here's a refresh....good luck with the project....I'll be back on it myself in the fall!https://drive.google.com/open?id=18pjwc4mbyO6n-hW5...
Hi...sorry for the delay....here are my STL's....I had to clear out my google drive a few months back so the prior links are broken. Been busy lately but I hope to build the circuit board very soon! Hope folks find these files useful....Art.https://drive.google.com/open?id=18pjwc4mbyO6n-hW5...https://drive.google.com/open?id=16DozbDExF2HJoGDlU-0FHH0CLse101ft
Build a DIY Desktop 3d Scanner With Infinite Resolution.
Hi.....you can pull the zip file from the below link...it contains 2 STL's....box and top. The box has no special printing requirements, the top must be printed with supports, use your own method of choice to close the box...I drilled holes and used nylon bolts but some type of adhesive would work as well once you're confident everything inside is healthy. I'll have the link active for a couple weeks....thanks for your interest :)https://drive.google.com/open?id=120NWZKfreIlCZdg3I3jZ79p0DL4NXZt-
Coils are connected, housing closed up.....circuit board construction next.
I've been able to scrape together a couple hours here and there for the project.....so I'm still in the game just on a slow schedule :)The physical assembly aspect of most projects is my weak spot and this one is no different for me. I attempted to source a ready-made solution for the coil housing but unfortunately was not able to do so.....instead, I put my 3D printer to work and created a clam shell type of housing which holds all the coils (epoxied down) in the geometry spec'd by the author. The next step is to attach the 8 cables and build the circuit board. I'm the first to admit that I'm a horrible CAD designer / user but if anyone would like the STL's for the housing just let me know and I'll post them. The design was done in Tinkercad which is a great on-line application for v…

I'd say check the polarity of your MOSFETs first...make sure you have your gate, source and drain pins connected to the appropriate polarity.....after that make sure your LED's are also hooked up to appropriate polarity. One other important thing...I used a separate 5V power source to run the LED's as they do consume some power....the display panel I used just happened to have a nice regulated 5V source which was sitting there doing nothing so I put it to work. ********Also in your photo I don't see anything connected to the DC input jack...you appear to be running off USB only......that's a red flag right there....plug in a good DC source around 9 to 12 volts to make sure you have sufficient power to run that thing*********
No problem...I would recommend loading the code into your Arduino mega as a first step just to assure that your system is stable before attaching the peripherals.
Sure....you can download the zip file with my latest code here....just make sure to add the required items into your library...good luck!https://drive.google.com/open?id=1jXc383kBqhRcWu4j9Ip0xd6JO1Ib5wVz
Please do...thank you!
Sure anytime....let me know how it works out...I've had a very busy year and don't anticipate getting back to this project until the fall!
Here are the links to the spindle STL's....I'll have them available on my drive for a couple of weeks.https://drive.google.com/open?id=1KYbebipr4RWaZakp...https://drive.google.com/open?id=1hsVv8FsP7N962p_7...
STL's are available for download...check prior response.
I'll be back in my office/shop next week and will post a Google link. Look for it Wed or Thurs.
Really Easy Crock Pot Super Soap
I did some digging around and found some newer RF24 libraries....there a "lite" library which offers very simple Tx/Rx operation....I think it would be ideal for this application because all you really need to do is throw a byte or two out to the weapon to activate the pager motor....the Mirf library is disastrously complex....I'll give this a shot but it'll probably be spring before I have any results....too many things going on right now :(
Got one question about the display.....If I load the sketch and connect the shield/display without the supporting circuitry, i.e. just the Mega and the display will I see options on screen or does the software need some kind of input to begin displaying? Thank you.
Yep got it now, thank you! I should have read all the comments and checked the code first....had to change to ILI9341.
Hi....you can retrieve my latest working code from here:https://drive.google.com/open?id=1r9QJ8lTMK1jkaRZ89gsL9Ex6HUsjUUf4You may want to get it sooner than later because I clear out my google drive pretty often :)I haven't been able to get the RF-buzzer portion of the project working yet....the Mirf library and all of its operational requirements may be a bit above my pay grade so if anyone else can assist that would be great. Otherwise everything else works fine with this code.....good luck!
How To: Sonar Sensor
Thanks for posting this amazing project....I'm hoping to get a working rendition within a few months. Parts are on order but in the interim I've wound the coils on very thin 3D printed spindles to speed the process and hopefully give me some flexibility when it comes to mounting them in some kind of enclosure.....sort of just drop them in with a little hot glue as self contained modules and close everything up...got a few photos attached here and if anyone is interested I can supply the STL files for printing!
Thank you for the project! I'm an EE who needed some brushing up on C-coding and my daughter is a fencer who's absolutely thrilled with this device....good stuff for both of us!!

Electronic Fencing Target
As an addendum to the below I was also able to get the bounce.h library working so no more switch bounce issues especially in Exercise 2. If I hear crickets on this page for the next couple of weeks I'll assume the thread is dead otherwise pls request updated code.
