The board design has been updated for surface mount. I looked into ordering, but there didn't seem to be any benefit over the current solder version, and the price was obviously higher. I could see how a commercial version could go that way (how is tilt designed??), but no point for DIY.

Not sure that would work as most of the 'girth' of the device comes from the battery and not the components mounted on the pins, but you should be able to sand down the sides of the boards quite a bit ? I'm in the UK, and postage of the pets from Europe was still >week and cost more than the...

Hi all, I recently built myself a couple of these from parts, but as things are far cheaper from china if you bulk-buy, I now have some to sell. I am in the UK - but postage doesn't look too bad to the US or elsewhere. Selling for 60USD for tracked postage, or 110USD for TWO through paypal. Add...

I put some sugru moldable glue in the bottom and stuck the board in place. It shouldn't move now when charging, and that acts as the ballast too. I calibrated in sugar water initially, but then too regular proper SG readings the first time I used it in beer. I'll not use those readings to...

Temp control of my FV, using iSpindel output temp talking to Ubidots and firing off webhooks to control a smart plug/brewing pad. I've got it firing events at 21.75C and 22.25C. A PID would pull this right down to maintain an exact temp, but a 0.5C swing and a little overshoot is fine for me...

I tested the temperature this morning using a digital probe in water. The ispindel and probe were same sane to 0.1C. That'll do me! As for ubidots - the educational system is useless for triggering events. Delays are huge (hours!). I've created a STEM account instead, and it's instant.

To be honest, I'll get 'acceptable' beer by just putting the FV in the garage for 2 weeks and keeping a general eye on the SG. Playing with all this extra stuff just gives me something to play with :) I very much doubt I'd notice the difference in the finished product! With regards to the 'on...

Thanks for the advice. I'll do some testing on a FV of water and see how well it controls. I'm bottling tonight, so will have nothing brewing for the next week or so. I just assumed that the air inside the ispindel vessel would be fairly close to the temp of the beer - at least as accurate as a...

My initial interest was with the angle measurement, but getting the temp for 'free' caught my eye. What makes you think the results wont be good ? I will have a very basic setup - a 23L FV, with a cheap heat matt under it turned on and off to try and keep the temp within 2-3C or 'good'. I'm not...

Looking at those errors, it seems like a file system mount issue. How did you flash the firmware, and with what settings? Flash size is 4mb (I got similar errors when trying 1mb). Try a 5.x firmware and see how you go - that should boot even if you hardware build/sensors are connected.

I'm using v4 of the PCB as per this video: I don't have a sled, but the PCB slides fairly neatly into the container. I have picked up some sugru this morning and will see if I can mould some around the base of the PCB, and maybe higher up for balance, to stop any rattle and help maintain...

Woohoo! Soldering done, and everything seems to be working. Couple of questions.... I've read warnings about plugging in the USB intervace of the controller to the laptop whilst the battery is connected. Is that something to avoid? Also, the board rattles a bit in the tube. What is recommended...

Totally agree - it should at least catch the exception and write out a proper readible error.

Replying to my own post - rather then deleting so everyone can see a) I'm an idiot, and b) this is the exception you get trying to flash the firmware on an unbuilt device for v6+. Flashed v5.x and I can connect OK to the web interface. Now to get my soldering iron out!

This is driving me nuts... I have 2x Wimo D1 Mini, v3.0.0 I am trying to flash iSpindel before building the full kit. I have tried flashing using all the setting I can find in the thread - flushing out using the INTERNAL options, changing the config for baudrate, SPI Mode and and size - but with...
