    So I spent some time reloading the BPL and iSpindel but with no luck so I lodged an issue on Github

    https://github.com/vitotai/BrewPiLess/issues/82

    Based on the feedback I changed the iSpindel version 5.1.2 from the BPL extras and have modified BPL 2.7 with 20 instead of 12 per below
    Check ExternalData.h, find processJSON()
    bool processJSON(char data[],size_t length, bool authenticated, uint8_t& error) { const int BUFFER_SIZE = JSON_OBJECT_SIZE(12);

    I am testing how stable this is by monitoring the iSpindel with Putty and it has been updating on BPL every 20" for 45 minutes so far - fingers crossed Update still working after 4 hours

    I would be interested to know what versions of BPL and iSpindel others are using?

    Died in the proverbial after 7.5 hours and successfully sending 649 times.

    Recharging the iSpindel and will run again overnight

    I'm thinking about making a couple of these and from reading in here DIY seems to be the way to go for cost and wireless charging.
    Is the parts list that was mentioned early on in this thread still the best way to go? I read a few people upgrading/changing things but it started to get a bit confusing.

    One other thing I'm still unsure about is how you read the data. Can I just use my laptop and read it live over WiFi? Or do I need the BrewPi?

    Things got easier.

    Use this Aliexpress shop list but replace the 470 ohm resistor for a BAT43 Schottky Diode.
    For the board, buy this one: https://pcbs.io/board/cc3e8a392dc8a9521a15ef98ed3e7abace9f9888af7625a097aafc75fa2716fc
    For the PET tube, use this one: https://www.ebay.com.au/itm/5-pcs-X...354252?hash=item1ed26ca48c:g:rnQAAOSwv0tU4JMN
    Use this drawer to make things easier, too: https://github.com/universam1/iSpindel/tree/master/drawer/mwx-Edition

    You can also use a wireless charger, but is optional: https://www.aliexpress.com/item/A-Q...32724345585.html?spm=a2g0s.9042311.0.0.oyw8Rh

    And NO, you don't have to build a BrewPi to read it's measurements. The iSpindel itself sends data to a website (usually Ubidots) so you can check it in realtime.

    Thanks for posting the shopping list, that will make things easier!

    I've just finished reading the thread so apologies if this is a silly question but regarding the sled, did you use the same guy others have referenced to do the 3D printing for you?

    Thanks in advance.

    No, I didn't.

    Actually I don't even live in Australia. ;)

    Hi guys,

    I'm struggling to make my temp sensor work. It is showing -127°c on the web page.

    Is anyone have a solution for that ? I did not removed the diodes though.

    Thank you all

    I had this problem twice. It was a bad soldering problem.

    I bought some parts last year for this but was otherwise distracted. I now have some spare time, components and the PET enclosures. Is there an updated ideal parts/build list since the last one @Paiakan posted?
