Hello , this time small combination padlock with Polish Combination Lock mechanism inside is going to Swynndla for next review. This small padlock has very similar construction to previous lock however it works very smooth. You do not need any force to rotate the knobs and almost zero force needed to open it. It will be nice to see Swynndla opening this small padlock. It has in theory only 10 000 combinations but here due to 3D print limitations is only 1250 possible combinations therefore it is quite easy to open even going one by one.
Swynndla however will not go “brute force” but as in previous lock he would like to find the way to decode it. This is not 7 days challenge rather I asked Swynndla to do everything in front of camera since he unpack the lock till the final opening. In theory he should open it in less than one hour by going all possible combinations. I hope he will show his attempt and share his video with us.
The goal for me from Swynndla next review is to find out how ease is to operate this padlock. User experience of holding it and operate is the key for me to understand if anything should be improved here. Of course the numbers in metal version will be much more visible here the visibility is rather limited. This is no issue for me now. The most important is ease of operation and overall feedback. I hope Swynndla will like it as comparing to previous model this one operates without any force needed.
This small padlock has Seeger mounting ring (steel one) inside instead of the nut. This means Swynndla will not be able to change the code after opening it while special tool is needed to remove so small Seeger from the central shaft. Therefore fun is only one time game for him. I am very much interesting to see his impression about this small padlock and most important the user experience from operation, it will be all time pleasure because everything is working there without any special force needed.
This review would give me additional hints towards full metal prototype.
Current project assume that first full metal padlock will have 15 x4 knobs = 50625 true combinations (each knob could be rotated 15 times to change the code) and this is according to some experts enough for simple padlock.
I think that this time laser method will not works because of the size of this padlock but we will see soon what Swynndla will do with it.
Finally I have added some final words in my Next Step article:
11 July 2019 Swynndla has decoded my lock mechanism and therefore the challenge is over. You can watch Swynndla video where he explains how he decoded my mechanism. I would like to thank Swynndla for his participation, his passion and creativity in decoding. Here is his video: https://youtu.be/h1MYWwpqH2s
The mechanism has been decoded by Swynndla using a laser. In my thoughts section I have written what I think about it. I like to invite you to read the article “Next Steps“.
I am working now on full metal version of my Polish Combination Lock mechanism. Here is first concept visualisation. 4×15 code complication, 80x60x30mm body. More details will come soon. Still waiting for some feedbacks before final design.
Polish Combination Lock (white version) is now in USA and HelpfulLockPicker just received it. He will made his review very soon. HelpfulLockPicker is not participating in worldwide challenge. He received also the correct code in the closed envelope so he can play with my lock and then open it and show the inside. I would like to thank him for supporting me with his review and I am sure it will help to share this information and increase visibility of this unique mechanism.
Please do not pay too much attention to current design. Concentrate rather on mechanism and pros and cons about PCL combination lock mechanism.
Please visit my YouTube channel or watch more here.
Polish Combination Lock will be soon converted from printed 3D model to full metal production version. Please share this information widely.
Polish Combination Lock is now delivered to New Zealand, Swynndla should receive it very soon and next round of the challenge will start. HelpfulLockPicker (USA) should receive PCL as well very soon and his review we will watch very soon too.
I am very close to start 100% full metal prototype it is possible maybe next month depends on funding. If you like to see it very soon pleasedonate any funds by clicking on green mark on the right side. After first production I will send metal version for review, certification and then I will start mass production. Polish Combination Lock will be available as the padlock with close 10mm shackle and will be soon in my e-shop. I will ship it worldwide. The e-shop will be available soon. Stay in touch and share it widely please among your friends. People who donate and contribute to this development will have priority to purchase this unique padlock.
Moreover all people who donate more than 100PLN or 30USD or 25EUR or 20GBP would have personal engravings on the body and my signatureand the rest of people who donate less funds will have nice discounts as well.
The final price of this padlock will be set after certification and initial production.
The first production will be very limited because the mechanism will be produced with extra precision and very small tolerances +-0.01mm. I cannot tell you more at this moment. This will be the most secure combination padlock ever created in my opinion. You can subscribe my YouTube channel to be notified when the new padlock with Polish Combination Lock will be available. The operation will be smooth and easy and the precision will be incredible. The size of the padlock would be most probably around 80x60x30mm. It will be very similar to this image but it will have most probably 15 numbers per knob:
Hello, just few moments ago Swynndla has published wonderful pre-review video of my Polish Combination Lock. https://youtu.be/Pli70ILvhfI I like this video very much and the energy and hope to decode my lock by Swynndla presented there. Good Luck!
Swynndla is going to decode it soon and now he has asked people around the globe to share with him any ideas how to approach it. Please help Swynndla with your ideas. This is very important to test as many ways as possible to be sure that this mechanism is so secure as I think it is. I would like to thank Potti314for his contribution and wonderful explanation of the mechanism and disassembly process.
Please do not pay to much attention to design this is just basic example. Please concentrate rather on mechanism itself and the working principia which is very unique. The body design and the final shape could be completely different because this mechanism is highly scalable. I am sure Swynndla will make wonderful next review video so please stay in touch.
Today 17 June 2019 PCL has been sent to Swynndla to New Zealand. We are waiting for new video coming soon on Swynndla channel (Pre-review).
I also want to thank HelpfulLockPicker from the USA (here is his channel: https://www.youtube.com/channel/UCloseNEb6epWL36Ap_zZmow for making a review of my lock. HelpfulLockPicker does not take part in the decoding challenge, however, he agreed to review my lock. I sent HelpfulLockPicker today my lock (white version, this one: https://youtu.be/s_wCaYa5N5s ) for review. He can play with it and have already the correct code inside the envelope for review. This is great help from him to make it visible on the market. I would like to ask also LockPickingLawyer later for such a review without participation in decoding challenge. This is important to show to people new mechanism and to make it visible on the market.
