Would you mind sharing it here?

Maybe you can consider casting soft plastic or silicon, i think this would be ideal.

You need to be more specific about your project, so we can help.

There is some similar software out there: VeeCAD Stripboard Editor - http://veecad.com VeroDes - http://www.heyrick.co.uk/software/verodes/ Stripboard Magic - http://www.marlwifi.org.nz/other/stripboard-magic LochMaster - http://www.abacom-online.de/uk/html/lochmaster.html

Hello and welcome, It would be helpful if you post here some of the circuits you found that are close to what you are looking to build. What is the distance that the transmitter needs to be from the receiver to trigger the alarm?

I am suggesting to have a reader in place where the pieces will be placed and each piece will have an RFID tag attached. So when the piece come close to the reader it will register itself. Each RFID has it's own ID and will not interfere with each other piece and will interact with the reader only. The only issue i see is if one piece is placed in the range of the reader and another piece is coming in. In this case maybe the reader maybe gets confused, but this is something to be tried.

Is there one specific place where the pieces are placed? or distributed across the board? If't it's one you could use RFID technology but again the constrain is your pieces as they are small. The smaller RFID tag i found is 25mm in diameter.

The Electronics Project Design / Ideas section seems good. No reason to post it again here. Let's follow it there.

In this case i would recommend a microcontroller (programmable chip) that will continuously read an acceleration sensor in all three axes and if these values fall below a threshold for some time (you define it) the LEDs will flash. But to use a microcontroller, some knowledge of programming is required. The electronics part of this project is straightforward. Alternative you can think of an Arduino to power this project. That will make programming of the mcu more easy.

Is this device going to be attached to someone (wearable?) or it will be in a distance from a person?

That's really cool! Can you give us some technical specification about your led cubes?

CoryD, you should normally see the "Drag files here to attach, or choose files.." as you can see on the attachment below. If you can't see it, please report your browser and operating system and also if you have javascript enabled or any antivirus is blocking parts of a webpage such as cookies. I am attaching here 5 different telephone intercommunication schematics that was published on the old version of electronics-lab.com. They are old designs but may still be useful to help you with what you are trying to accomplish. I also have a telephone intercom system based on PIC microcontroller. If you are interested on this also, just tell me. TheOriginal2PhoneLinkDesign.zip TheLinkMarkIII.zip The Link P - Privacy Link.zip t_tink.zip LinkA2B.zip

Do you have an issue uploading a photo on the forum? What's the problem?

How much output current do you need?

I think the photos needs to be fixed.

As a starting point i would post this link: http://www.studentcompanion.co.za/web-based-control-and-monitoring-with-pic-microcontroller-mikroc/ Are you interested for a particular PIC microcontroller?

I have found these articles of using Matlab and Arduino to control a servo motor. Hope you find them helpfull: http://www.mathworks.com/help/supportpkg/arduinoio/examples/control-servo-motors.html http://www.mathworks.com/help/supportpkg/arduino/examples/servo-control.html http://www.allaboutcircuits.com/projects/servo-control-with-arduino-through-matlab/

Today, i have applied another major update on the forum software. Can you check if the upload function works?

It seems like a JavaScript issue. What brower/operating system are you using?

What problem did you experience while editing the post?

My intention is to try the new design for some months and see how it goes. Then i will decide for any change.

The cheapest PCB supplier i have found is this: http://imall.itead.cc/open-pcb/pcb-prototyping/2layer-green-pcb-5cm-x-5cm-max.html They provide 2 Layer Green PCB 5cm x 5cm Max for 9.90 USD. You may take a look.

I am sorry to see that the problem didn't go away with the upgrade to Windows 10. So I now suspect that something else is blocking the button to appear on your pc. Do you use any special plugins on your browser, like ad blockers etc? Also, have you tried to deactivate your antivirus temporary?

Some users didn't converted successfully to the new platform, so this might be the case, I am happy to see you registering again.
