I have heard that can be done, but can you suggest where I can find a 'how to' please, for OTA updating. I don't need to update yet, I'm running the current version, but for the future please.

Your switch is in the off position. Nearest the two reset pins = off. The antenna you are suggesting buying is of no use at all to you. If you intend mounting the iSpindle in a pet bottle. the antenna needs to be inside the pet. If I were you, I would look at trying to solder a few inches of...

Just a thought, might the reed switch not be triggered by wireless charging?

Look for drinks in your local supermarket, with the identical cap - hopefully you can enjoy the contents, before repurposing the cap. Remember the petlings are sold commercially to be heated and blown up to be used by manufacturers as drinks bottles. I have found a few spare caps, since building...

I may have found out what happened, because it just happened again - I powered it up and no data appeared in Ubidots, until I went into the iSpindel config and simply saved the config without making any changes.... My home network is quite busy with around 30 items on it, though not all needing...

That is the way that my iSpindel behaves. The thing is, you must be certain you get all of the settings in the configuration correct, before clicking save.

No, you should just need the turn the iSpindel on, it should flash the LED several times, then not flash again until it is due to transmit its regular batch of data. I had one incident in the middle of my last brew, where it suddenly stopped sending data. I eventually got it going by changing...

Log into your Ubidots page, click User (top right, the silhouette of the upper body symbol), a drop down appears containing API Credntials, click that. Next click the panel which appears at the top, where it says 'Click to Show', copy and paste that long API Key into your iSpindel's configuration.

Above is my resulting graph so far, 5 gallons of red wine. The first bump (top left) is what normally happens when a brew is started, it rises gradually then falls back down once the fermentation is properly underway. The second sharp pointed bump, is when my iSpindel simply stopped reporting...

Deleted.

60 seconds over the course of a brew is far more than needed. Probably it would lock you out of Unibots. I agree the Pi route makes it much more complex, too complex for most people. On its own, the iSpindel is a great solution - if only we could resolve this one issue or find a work around...

As said above, the big problem is having enough information to be able to work out which part is failing. The feedback from the iSpindle on 60sec reporting is OK, but at 15 minutes it is so easy to not see the LED flash. It could be the router and / or the website not accepting the reports, with...

After bragging about just how reliable and accurate my iSpindle is and in the midst (2nd day) of making my third batch since building it, yesterday lunch it stopped reporting from inside my FV. It is configured to report every 15minutes, to Ubidots, from my batch of red wine. I opened up the...

My V4 pcb is a perfect fit (once filed down slightly) for what I bought described as a 'BIG XL' PET, measuring Color Clear, gently grey Dimensions (external, MAX), mm ~135 x (d39, d43 MAX) Dimensions (internal), mm ~123 x d33

I would guess your iron is not man enough for the job, or the tags of the holders are maybe stainless steel and ordinary electronic solder struggles with SS. I haven't used a holder, rather I have soldered the battery to the board with flying leads and stuck it with double sided tape. To not use...

Sorry, I should have said - I use plastic bottles and as I fit the cap, I squeeze them to expel any air above the surface.

I begin with my funnel sanitized before I begin, fit the funnel in each bottle in turn, add the 1/2 teaspoon of sugar in the funnel, then wash it it with the beer. Fit the top, give it a good shake and put to one side. Once all are filled, I give each another shake and store away. To get my 1/2...

Some people have found that eventually, after extended use, the softer plastic material of the PET caps can split. I have been on the look out for one which will fit, for when my cap splits and found one on a plastic drinks bottle I was about to put in the recycling bin. The cap is blue in...

I meant everything integrated into one single pcb, instead of the present three pcb's mounted on a main pcb. Going surface mount with the main pcb, is rather a pointless exercise for just the three discrete components - it saves almost no board space.

That sounds doable, but trying to integrate all the components onto one board, would certainly be an expensive, commercial solution rather than a DIY option. There are not many people who have the equipment and even fewer who could manage to cope with surface mount assembly.
