Oops missed that! I just saw the ucfl and ASSumed...

Subbed!!!!

I have my parts on order.

 

[toadyus]

Yep, just bought parts to build 5 of these...going to be around $40 CAD each lol

Nice!! let us know how it works out

Do you think it will fit to those lab falcon tubes? https://beta-static.fishersci.com/images/F14776-01~wl.jpg
I have tons of them

I don't think so...the current spec requires one that is at least 15cm long and at least 4 cm in diameter.

 

[terragady]

ops right, didnt check the dimensions. Even wemos will barely fit there Is there any china supplier for those? Or how I can get it or something similar?

I bought this preform soda bottle but i still haven't received it, ill let you know if it fits on the Wemos

That one should be wide enough but It's not long enough as it's only 13.5 cm You need the XXL as it's 15cm, you can get it from the same seller. I bought 5

damn! really hope you are wrong hahaha and everyone's should work fine, should get it any day now.

 

[terragady]

probably you will just need to fit everything inside Although I just read on german forum that dimensions etc are crucial for the developed software.

Skimmed the thread so may have missed the discussion of this, if I have - apologies.

What about doing a low power solution like BLE? Something along the lines of an Adafruit Bluefruit device https://www.adafruit.com/product/1697?q=nRF51822&

And here is an out of the box idea - no battery - but that probably won't work due to range (unless maybe you could tether the free floating part of the device to a charging pad affixed to the side of the bucket - but of course that would greatly increase the complexity of the project)

Congratulations! You are the first person to use the "I skimmed but didn't read it all" line in this thread!

Sorta like this?

Would be cool for sure. Complexity off the scale compared to this.

This project just appeared on Hackaday. There might be some useful insight in the discussion (although I won't be holding my breath).

So...bought both and it looks like the XXL is the right one for the 3d printer part and neither will fit in a glass carboy, good thing I use buckets lol

Rather than just subbing i'm really interested in this I've read the thread and can't really see anyone having posted a link to all the parts that are needed, so i've pulled some together a list of all the components but being a novice can someone double check, that all this would all work. there are a few parts missing.

The Pelting container and also the little 3x5 board, and the sled to fit it all in.

iSpindle Aliexpress wishlist you can make you own decision about whether you want to buy batteries from aliexpress, the components wemos etc have always seem to work pretty well for me though.

The Petling is here ->eBay which is the one linked previously in the thread. the thing i'm not sure about is the molding break that is at the top it looks like a dream for harbouring nasties.

the 3x4cm PCB

The Sled for the life on me i can't download the STL file, but given my search for low cost 3d printers in the UK, it'd probably be cheaper for me to just by Tilt itself....

Does this all look about right? if so it comes to around $30 - £24 plus the sled and a PCB so pretty good value.

I'm really tempted to get my soldering iron out again and give this a bash...

Looks like you have everything, i still havent received all my parts but its the same but from a different seller, i wouldnt buy the resistors since you can probably get them cheaper locally, the sled you will have to 3d print for sure and for the board shield, the guys from Wemos make one specifically for their boards.

 

[pocketmon]

While still waiting for the soda bottles, a very kind friend promise to make one for me.

Right now, I am working on gravity-based temperature schedule. Can't wait to test it.

Well I've not placed the order yet, I'm struggling to visualise how it all goes together what goes into the sled etc.

You just need to do a little bit more research, its in german but chrome translates it for you

[ElChangoGuero]

So it looks like the sled is a little big for the tube, gonna have to take a little of the edges

Thanks for putting together the shopping list; ordered everything except the batteries, looking for the non-explosive kind.

Looking forward to doing this project...

Thanks, i've gone through this, it's a little bit as clear as mud, i have translated though.

I think i follow it up until point 6. untwist the wires....

I might try and map it onto a breadboard and share it if someone fancies taking a look to make sure its right?

But that last bit attach the battery, do you literally just solder the wires directly to the battery?

I just subbed to this thread. It looks like it needs some work but it is a really exciting project.

As soon as i get all my parts ill start finishing this, but yea instructions are not organized in the easiest way.

and yes, solder straight to battery i would think so it doesnt move at all

I'm trying to make sense of and redraw the diagrams in photoshop. Taking a leaf out of the ESP brewpi lot as well I've taken a first bash at creating a board that (given the small size) would only be a few £s each. But it's my first attempt at both using fritzing as a basis and designing boards but there doesn't seem to be a lot going on with this so it should be easy.

I was thinking about doing the same thing. Just for the experience- I don't think I would have the boards made.

I created a PCB for this project last week and learned German just for fun so I could write it all in German to match the original site. https://github.com/universam1/iSpindel/blob/master/docs/iSpindelPCB.md

I'm kidding, of course. It looks like they have a pcb that is designed to take the place of the 3D printed sled and house the boards, too. Might be a cool project.

Actually kind of makes sense to create something to fill the pelting, I guess in theory you could create something with a curve of the in radius and it would fit perfectly. If not a little expensive.

I suspect it'll be cheaper for me to spend the €60 and buy it via the iSpindle GitHub link. Given the cost of 3D printing over here. But a PCB would look so much neater and less likely to fail due to my dodgy soldering.

That and having to cut down the PCB to 40x30 to make sure it seats properly in the sled...

Actually thinking about it after a few beers a PCB tonthe sleds dimensions could potentially be cheaper than a printing the sled and weighted to the correct weight with airdry clay or something?

Which file did you print?

There are 4 files in the "drawer" directory, and there is no words about it.
