Hi - There is a separate code base and circuit for the HKC alarmshttps://github.com/OzmoOzmo/CastleHKCArduinoRKP

Thanks - send on the code changes you made and I can see about adding them to the code. I've only been emailing gmail and they didn't have issue with the format.For the web site - by default the address is this:http://192.168.1.205:8383 You will of course need to change to be an IP that's valid on your lan (eg. 10.0.0.205:8383 or 192.168.0.205:8383)Maybe try a different browser also - Chrome and Safari works fine. If its still not working - Check if there are any blocked network traffic (using the Browsers F12 menu to see console errors and network tab for network errors - might be a port you need open on your router)- All the best :)

Thanks for the kind comments-Edison’s are tricky to come by these days so here is the same project I remade using an Arduino or clone...https://www.instructables.com/id/Arduino-Steve-a-Minecraft-Animatronic/:)

Old Parallel port flat-bed scanners are a bit tricker to come across - but the lens in them is really powerful and makes a perfect magnifier just as is.

Hi- you need something like an Arduino- a pc might not be responsive enough - the protocol is very demanding on timing- the panel sends a message and the keypad must respond within a few milliseconds.Each message has a header with the keypad number it’s for and the purpose of the message- eg. check key press or display message- and the last byte is a checksum. This is all documented in rkp.cpp in the code. Have a look there and see if there are any questions- I’m currently porting this to Esp32 boards which are more powerful and have WiFi built in.

Hi-Thanks for the nice feedback!If you could send a photo of the back of the circuit board as well ill check it - thanks.Id also try the connection using the single diode method.. This will make sure the code and Arduino etc is all ok.I have a CD72 myself and it does work well with this panel. Good luck!

Nice project..."ESP-01 has only two pins.."With the ESP-01, you can use the RX and TX also as regular pins when not programming - so eg. two of the pins are easily usable for I2C devices like graphic displays leaving you two inputs free.There is also info out there for soldering on more wires to get access several more pins on the chip that are not connected be default.I like these ESP modules because they are so tiny and use so little power

Use the original pins from the lock and reassemble maybe - as long as the height and order of the pins in the lock aren't changed you can use the same key.Nice tip using the drill as a lathe - worth the instruct-able just for that.

Thanks for the breakdown - I find the China sites great for supplies like these at a fraction of the cost of the more usual shops, (at the expense of 3 to 4 week postage times) - this is a good site and would have most of the electrical, painting and magnet items on your expense sheet.http://www.banggood.com/ There are even cheaper sites (like aliexpress) - but I prefer the above as its just the one seller you are dealing with.

Yes - That would be great thanks :)This Ethernet shield is great to work with!

Yes - That would be great! Thanks for making great ethernet chips we can use with the Arduino :)If you let me know the link when its there I'll update the instructable with it.

You could try the calculators in the link below to get the correct value - as stated here, it will kind of work without the resistor (no resistor limits the lifespan of the LED) - but adding a resistor will make your AA batteries last longer as it will allow you to reduce the current taken from the batteries.https://www.instructables.com/id/Choosing-The-Resis...
