a cheap RF 433.92MHz OOK frame cloner

Similar projects worth following
The OOKLONE device allows you to capture RF signals (or frames) from equipments operating on the 433.92MHz frequency, and replay them at a later time. This way, you can clone the original equipment functionality. Such equipments include device remote controllers. Please see the following videos for examples including wireless wall outlets and car door locks:

In its current implementation, the device includes:
. standalone power supply using 3x LR03 batteries,
. a flash memory to store the captured frames,
. a selection switch to select the frame,
. 2 buttons for playing and recording frames,
. a serial link for development purposes.

A next iteration of the device will focus on implementing mechanisms to defeat anti replay schemes in some extent. Also, proper schematics and CAO files for a 3D printed case will be added.

The initial device prototyping and first tests are detailed in a blog post here:

User interface


The device firmware and related tools source code are available in the GITHUB repository. Final schematics and CAO for a 3D printed case are still to be done.


Here are some possible logo. This is work in progress, you can find the GIMP files on GITHUB. Let me know which one you prefer or if you have your own proposal.




  • 1 × MOTEINO board with RFM69 option handle signal capture, pulse slicing and replay
  • 1 × lm317 Power Management ICs / Linear Voltage Regulators and LDOs
  • 3 × LR03 batteries batteries
  • 2 × buttons record and play a frame
  • 1 × switch turn the power on off

Hello I know this was a long time ago but I've just one question, do you need to record the signal or is there a way to bruteforce it?

  Are you sure? yes | no

Hola saludos desde España, me gustaría comprar un OOKLONE  seria posible? Tengo ganas de probar el aparato, si tengo la oportunidad de comprarlo como puedo hacerlo... saludos

sorry but it OOKLONE is not available for sale. However, you are at least the second person asking to buy a product, and I know it may have some level of success. So I may consider that more seriously ...

I probably should have waited for your results from seedstudio, but I went ahead and sent your sch files over OshPark. Ill post my results once I receive the PCB in the mail. I look forward to testing your OOKlone unit and experimenting with anti replay circuits. As your time permits, please continue to post updates, this project has me really excited! Thanks for your hard work!

I hope the PCB is correct ... I did not have as much time as I wanted to review everything in details and there were some tradeoffs to make it fit the 50x50mm frame. I will post results, please let me know yours.

  Are you sure? yes | no

PC Boards arrived today. Still waiting on the components to come in the mail...

Ok, let me know when you have completed it. Mine should arrive soon too, this week I hope.

Awesome project! This has been my favorite on HaD projects so far. The demo videos are excellent. I'm surprised you didn't get into the semifinals, but the projects that made it were pretty nuts too. Anyway, I hope you keep working on this project! I'd love to see how it develops.

  Are you sure? yes | no

texane wrote 08/26/2014 at 06:45 point
Thanks for the support. As you said, projects that made it are generally very good at least, so I am not surprised OOKLONE was not selected, even if I hoped it would have been :) I have a few features to add, plus schematics and possibly a 3D printed case, so stay tuned :)

  Are you sure? yes | no

Really excited to see where this project goes. Ill be buying components and testing this myself.

  Are you sure? yes | no

Thanks for your interest. I will make a cleaner and more complete version after I played a bit with the prototype. The core component will still be a RFM69 chipset. I may change the ATMEGA328 for a CORTEX, but will try to keep the code portable. Stay tuned !

I curious as to how the data comes out of the RF module... is it noisy as with the cheaper modules? O-Scope screen shot?

  Are you sure? yes | no

texane wrote 08/14/2014 at 05:37 point
Good question, I do not know about the SNR. I will have a look at the spectrum with RTLSDR and post info.

  Are you sure? yes | no
