You think so? You also need a relatively expensive 3D printed sled. Regarding that the design of
@Open Source Distilling is much more elegant, just a custom pcb, some parts a battery and a tube. And no lose wires, the battery is in a holder soldered to the PCB.
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 have a 3d printer you need to either order a circuit board or 3d print and then you either need to solder 2 components together or, I've lost count 7 for the iSpindel? Also, you can probably get a friend to do a 3d print for you, or at least get it don locally, which probably isn't the case for a custom circuit board. The Floaty wins easily for being the more elegant of the two.
I assembled the floaty in a few minutes and it slides right into a 50ml tube, while I have had the pile of parts for an iSpindel for weeks while I try to figure out how to fit them together to do the same thing. Maybe if I leave out the temperature senor and modify the code - not straight forward at all. I am annoyed that both default to using the unobtanium preform that you need to order from Lithuania or something. Of course I already have a 3D printer so even if I was building an iSpindel in a preform I would still do a 3d printed version rather than the extra time and money of ordering a custom circuit board, which I still think is an unnecessarily complicated way of putting together off the shelf components.
For the record, I'm actually hoping to build both and it does look like the iSpindel has several advantages, not the least of which is a large user community, but also the fact that it is open source and you aren't locked into the developer's app or paid software.
I found a container for 50ml syringes at work with a lid and a great shape. Spent ages fiddling and fitted the Ispindel in on a modified sled with an induction charging loop in the lid. It was a sealed never to open unit.
Unfortunately the LDPE container buckled during the pressure ferment badly, didn't leak but became laughably inaccurate. Very irritating.
Do you mean a 50ml centrifuge tube or actually a 50ml syringe? How did it buckle? Was it a temperature change? The centrifuge tubes are easy for me to get. I already had one and asked a friend who works in a lab and she gave me a handful for free. The certainly aren't as rigid as a preform, but I'm surprised they would buckle. Luckily I don't like lager so would usually be fermenting close to the temperature I assemble the hydrometer at
edit - oh sorry, rereading I see it was a 'container for a 50ml syringe'
