I've been really messed about with a PSU for my Fermentrack build, which I half started the end of last year. I've placed a total of 6 orders, 3 from Far East 3 from UK, nothing on my doormat yet! So, in frustration I've used a striped down 2 amp USB charger until I get a "real" PSU. But what...

@wd16261 I had real trouble making an actual hole. I tried a pin, but my hole started to close up, the burr created settled back partially covering the hole requiring the shrink to be moved a few times. In the end I used the smallest drill bit I could find, pushed it right through to the...

So, a quick bit of testing and tinkering this morning... The insulation tape I have is not sticky enough to remain in place if handled too roughly, the cardboard and double sided tape seems a better option. As @wd16261 has already tried heat shrink and I hadn't I gave that a go, I thought I'd...

Certainly with the variability between the two brackets I have it's going to be a problem. I'll try a few experiments with "things" attached to the sensor. Open to ideas and suggestions?

So... I've got the 3D print back from my friend. The fixed colimator is really difficult for me to get working. On the PCBs I made I can't get them to remain in the relative position to the hole in the support and I eventually lose the count. On the print I received I had to take off...

@LBussy Lockdown has been eased in Enlgland, so I can now travel for exercise, but maybe you're a bit too far? If you have some ideas, I'm more than happy to print out locally a beta version if you have the files? Chris

@LBussy I'm in need of another BrewBubbles setup, I've got everything except the bracket, is there anything new on the 3D printing horizon? Or shall I get a print of the existing version? I know I'm getting greedy having several fermentations on the go at once, but that's exactly how...

No problem for me. My integration is going to be with Fermentrack when my PSU finally arrives... By then maybe I can log BrewBubbles data? Next wine just started, yeast just starting to yawn and stretch! Chris

@LBussy The temperature thing I only mentioned in case it was one of those things "overlooked", it's not an issue! Also, I don't have a 3D printer myself but I do have a friend with one and I get most of my "toys" built by him. More than happy to keep him busy! Anything else you can think of...

I have looked at the signal output from the sensor with my 'scope and I've also had a read of the datasheet. There is nothing I can see on the output from the receiver that is usable. My interpretation of the datasheet is that is definitely a go/no go output, the trigger level for this is set...

I've definitely destroyed a sensor! Built another PCB and all's well. Seems that the receiver is a bit sensitive to heat? I've read the data sheet for the GP1A57HRJ00F and it implies that it's a detect/not detect output. From my quick test with another lock, filled with just water initially...

The outside dimension of where my sensor is positioned is roughly 7mm, maybe a bit more but not as much as 8MM, measured by eye. I've checked on a couple of other locks and they're the same. Chris P.S. i think I've just blown up a sensor! I had two PCBs assembled and added two wires onto the...

So here's my kit of parts from yesterday; Ordinary household scissors, map pin, cardboard and double sided tape. I used the scissors to cut a strip of cardboard roughly the same width as the sensor housing. I then cut a piece off that strip that was just a bit shorter than sensor housing...

I'm thinking the same thing, all I've proved with this "test" is the technology CAN work. I'm going to get the 'scope out and see if there's any change on the receiver that is easily measurable/detectable. That is, can a threshold be set to trigger the count. My current fermentation is nearly...

I think I may have a/the solution? A sliver of double sided tape, a sliver of carboard (could be something more robust for a long term solution) and a pin (likewise might need a drill bit)! Make a small (very small) hole in the cardboard just above the IR Receiver. Stick the carboard so the...

I sourced my devices from a "real" shop and are all labeled 1A57HR SHARP 8Z. OK, I know that's no guarantee that they are genuine parts but I did my best? I've built two and both are behaving the same, I'm sharing the D1 Mini between the two BrewBubbles PCBs. With the type of lock I have I'm...

@LBussy I've just upgraded and all went well. One observation, I have one temperature probe connected and that's working OK, the unused channel is reporting a temperature of 0.06C, previous version reported 0C. I'm getting a few more colour dyes/additives to try today as I'm now not counting...

I'm getting some bubbles counted but not all, OK I know this is a known "issue" with Infra Red and water, but what have other people tried to make the water more opaque to the Infra Red? I've tried a couple of store cupboard colours/dyes but nothing so far provides any consisency. So for...

I've received all the bits and built my first BrewBubble! I can confirm it counts fingers, cutters and paper extremely well, going to start some wine off in the next few days and I'll report on findings. One question I can't easily work out from the documentation is how to configure so that I...
