Thank you very much for showing how it's done. 🎉

Merci ton tuto est parfait Ce qui est débile c'est que les vendeurs de batterie ( amazon pour moi ) pour le EW1211W vendent les accus 1 par 1 , et bien sûr n'en ai acheté qu'un seul ( 11€ ) , là je dois en recommander un autres ( 11 € ) , ça fait 22€ d'accus pour la réparation....

Why can't they put easily removable batteries?What stupidity and harassment fir users.

Merci pour ce tuto, j'ai le modèle EW1311 qui est quasiment le même pour le démontage. Mais le mien était plein d'humidité et de moisissures à l'intérieur, j'ai acheté un modèle sans marque connue. Je verrai bien à l'usage, le Panasonic avait duré 3 ans et demi quand même. Là où d'autres de marque non connue avaient lâché avant la fin de garantie les années précédentes...

No need to remove so much screews, just 2 at bottom and 1 on top. Water tank can stay.

Lohnt bei den Akkupreisen nicht.

Thank you very much for uploading!!!

Thank you Alex 😘

I just don't get how are you gonna pressurize the chamber without having the pilot chamber at the same pressure. I mean, isn't it more reliable to always fill a qev operated chamber via the pilot valve? I belive that, in your design, this could be accomplished by a port trough the red piston itself, without a side port. Fill the cannon through the pilot side and wait for the pressure to rise inside like any linear gauge would do, until, as you say, the red piston feels a pressure higher than the spring can hold and...jumps Did I miss something? Edit: sorry, I may sound rude. It is actually a great idea. I'd really like to know anyone's opinion on the question I ask. My qevs are all homemade for coaxials, so there is no chance of filling the chamber directly and I may be missing some operating options here Thanks :)

I love this modular easy to repair design, but the machines gets wet easily inside followed by corrosion. Also mold is problem.

Bonjour j'ai le même hydropulseur mais il ne fonctionne plus. Le voyant ne s'allume plus comment faire ? Merci

Thanks for the disassembly video! Sure was easier than I expected! A couple of AA batteries does just fine, even better because AA batteries are easier to find in good quality. The receptacle terminals can be slightly bent to make contact with the battery ends, even without the weird bars.

Thank you for the very clear guide. Got 1/2 way there and still had to explore the little Torx screw in the top end.

Thanks a lot...... The gadget is perhaps designed in a way that the batteries can't be replaced...... It was a major hassle right from opening it, sourcing the batteries and assembling back. It wouldn't have been possible to do but for your guide

mine one cannot broken, device not suck the water, where I can check and fix it.

Thanks Alex, could not have done this without your video, very fiddly to do. Try to avoid the batteries going flat by using it regularly.

Need some help. I'm trying to do a clear G36 build and need to find a clear plastic V3 gearbox. What kind of AUG did that gearbox come out of?

Thanks !

thank you

Thank you, very good tutorial; I've just changed the batteries now :)

Thanks

Good for few shots

Its so cool. I hope find diagram and scheme

Perfect for airsoft

I bought my battery from Espares and after replacing the old one the water jet worked well for a while but it didnt last long. Now I get two uses before the battery goes flat. Either its a counterfeit or its a manufacturing fault.

Thank you, I just repaired two of them.

Alig bonyolult az elemcsere. Szerszámkészlet mellékelve? Hihi.

Judging by the cleanliness of this machine Alex is working on a new one. I found the batteries didnt come out anywhere near as easily as that, some corrosion had set in around the terminals and 'welded' them in. And no you do not need to remove the torx screw.

Thank you Alex; I had exactly the issue with dead batteries, ordered the replacements, followed your guide and we are as good as new again!

Very kool! Thanks for your pulling it a part, putting it together and making such a great video!! I have an EW1200 and it is non functioning although the base has power.

You don't need to remove the torx screw to replace the batteries. Also, I have a manual for the original EW1211 in 18 languages including English. I don't mind uploading it somewhere if somebody needs it.

Bonne vidéo, au bout de combien d'années les avez vous remplacées ?

Klipp und klar. Machas gracias!

What is the battery size? I want to check if an battery type AA may fit.

Very many thanks for this useful vid. My EW1211 seals had failed and caused water damage to the PCB. (They need conformal coating really.)

Thank you very much

I have a similar model, only that it's the "w" variant, and it held it's power consistently throughout the 2 year lifespan, but now it suddenly loses power, can be this be due to bad batteries?

Are all the steps the same for Panasonic EW1411?

Thank you so much, Although once you got to pulling the battery and motor internals out, it looked just like a sex toy, as I have done this for a friend who watched me pull it apart and then said "if I had of know it was this complicated I would have just bought a new one" I then Glared at them very Sternly.

Thank you very much. I replaced the batteries in ca. 30 Minutes. When reinstalling, you have to press the start button, otherwise it will stucks.

Nice thankyou for the vid. Was able too open it now in the proper way. Mine is a litle bit differant from inside. I see i only got to order the replacement battery's somewhere hehe. Were did you get the battary's?

Bravo pour ce super tuto très utile et très bien fait. J'ai aussi trouvé les piles en France à peu près au même prix sur www.adepem.com/dpm182547/batterie-1100mah#compatibility.

Thank you!

Do you really need to remove the little scree close to the straw? I am missing that head.

The idea was that you would connect the second port on right (the far right one is just a vent to avoid trapping air behind the piston) to a compressed air source and when the piston is pushed all the way to the left by the spring, the air would flow into the middle port and fill the chamber of a potato cannon. The threaded port on the left would be connected to the pilot port of a Quick Exhaust Valve (like traditional 3-way valve). As the pressure builds up in the chamber the force on the piston increases until it moves back just enough for air to leak out and and pressurise the full face of the piston. At that point the piston is pushed back more violently exposing the second port on the left which connects the QEV pilot to atmosphere firing the potato cannon. When the piston is pushed back, you'll notice the air supply to the middle port (going to the chamber) is cut off so no air from the supply is wasted until the canon has fired and the spring pushes the piston back. The cycle then repeats. The screw on the back allows adjustment of the spring compression to adjust the firing pressure and rate of fire.

Would you be able to share how did you do it? Working on similar project atm

Hi! What kind of sensor are you using? And is it possible for you to share your code fro this project?

diagram please!!

Hi Which mode did you use for flipping? I see a Flip mode in the list of modes inside ardupilot,is that it?

how it's work ?
