OK, thanks, no rush. I wanted to see if being able to see my brewbubbles and floaty hydrometer data in one place was worth the premium subscription cost, but I suspect it won't be. Looking at two different web pages or apps really isn't a big deal.

Hello, I'm a very occasional brewer that made a brewbubbles a few years ago. I'm doing a batch right now mainly to test using Brewfather (still in the 30 day premium trial). Brewbubbles is working well and I can see the data in Thingspeak, but not in Brewfather. After a few false starts, I think...

I am interested too. Just be aware that although the widest component is the D1 mini, depending on how many parts you solder together and how you fit them together, you might need something a little wider. I have a little perf board that is exactly the same as the wemos d1 mini, but with the...

I might be using "elegant" in a way people aren't familiar with. In the scientific community an elegant experiment is a simple one and the Floaty is much simpler than an iSpindel. I don't necessarily think it is the best option, as I mentioned, I am trying to build both. I do have some similar...

Thanks. I have also spent a lot of time looking for a suitable, affordable, easily obtainable container and the 50ml centrifuge tube is the best option I have found so far. There are 100ml tubes on Amazon, but they have metal caps that don't look like I want them in my beer and you usually have...

Yes, I really do think so. That the floaty is more elegant, much much more so than the the iSpindel. Just two parts to solder together compared to many times that for an iSpindel. You can't really argue that the Floaty isn't more elegant, elegant in this case meaning more simple. If you don't...

Yes, the Floaty really is elegant, just two inexpensive boards and a battery. I have to order a new LOLIN32 Lite to give it another try. While I wait I have a MPU6050, D1 mini and matching perf board, and even the temperature sensor, just not the charger or resistors, diode, or the...

I did see a Cherryphillip74 design for a 50ml tube, but the thread seem to have gone stale and for several reasons I'm not interested in custom PCB versions. Mainly I would like to use my 3d printer, but it also seems like a complicated, expensive and time consuming way to solder togther off the...

I am super interested in figuring out a version that fits in a 50ml centrifuge tube. The path I was going was to use a 18500 LiFePO4 cell, sold in hardware stores where I live for solar lights. They are still a decent sized cell, the one I have is 1000mAh, but small enough that they fit in a...

The floaty people mentioned resistors, but I would have to find a schematic because the parts are gone. They are some almost microscopic surface soldered parts up just below the antenna. In the V2 3D printed sled the board is held by antenna end sliding into a slot, which seems to have a...

After many many many messages exchanged with the developer we finally discovered the problem. The improved second version (V2 not the one in the video above) of the 3D printed sled is designed so that it scrapes some of the surface soldered components off the circuit board when it is inserted...

Has anyone here tried building a "Floaty" digital hydrometer? I have searched and haven't found anything. It seemed simpler than the iSpindel, but when it didn't work I've had trouble finding help. It is based in Spain and although they do reply to help requests, the time difference makes this...

This is the full package Lee designed, custom PCB with sensor, resistors, and capacitors soldered on. It does still detect something solid so it does seem like it is an alignment issue, except, it has stopped counting twice now without being touched/disturbed. Not only that, but it seemed pretty...

I just had a regular rubber band and I thought I had tried all possible adjustments including going back to the non-collimator bracket, but going back to the collimator bracket and adding a thick elastic band seems to have it working again :oops:. Thanks! edit: no, it stopped again without...

Has anyone had their just suddenly stop counting? Mine went to zero abruptly and fiddling with the position and changing to the bracket without the collimator as well as rebooting hasn't fixed it. There are still regular bubbles the sensor just stopped detecting them. Putting something like a...
