    Raspberry Pi vs Arduino vs C.H.I.P vs Photon (inc. Poll)

    If you're wondering about the CHIPs (that nobody voted for), the CHIP is like a Pi Zero but with Bluetooth and WiFi built in and it costs a little more ($9 vs $5 for the Pi Zero). My boards arrived about a week ago so here are a couple of pictures showing what they look like... I'm absolutely...

    Heated Digital Stirplates

    Thanks for the lovely feedback guys! We've recently sold a couple to Norway so it will be great to hear their feedback on the heating performance. Also, sorry drewchad, the coupons ran out at the end of last year.

    Another DIY stir plate

    Exactly. No need to spin it like crazy so long as there's a decent vortex IMO. Good luck with the rest of your build!

    Another DIY stir plate

    Nice build, I like that it uses a 5v USB fan since power adaptors can make up a big portion of your build cost. I wouldn't worry too much about the pivot ring in the middle of your stir bar, I've never found it to have much effect of the magnetic retention, but it will cause it to rattle and the...

    Font Fan run time ?

    *subscribed* I'm a bit of a mix, I often leave my font cooler on 24/7 when the weather is hot and I've got a session beer on tap, but if I need the power point for other things (ironing clothes, Xmas lights etc.) sometimes I forget to plug it back in and it's back to the frothy dark ages. :(...

    Just an update, I've put together some printable Yeast Forge instructions so we can include them with future orders. I hope they will be useful for anyone that hasn't seen the video and wants to get up and running quickly. Here's a .pdf copy...

    Thanks Dan, glad to hear the coupon works. Also thanks for the temperature probe tip yob! You reminded me that I've still gotta make an instructional video so I whipped one up this morning. I'd embed it, but I don't think that's possible on AHB these days so .

Thanks so much to everyone for the feedback and suggestions provided in this thread that helped make this product what it is. Also, special thanks to Yob for your testing, feedback and...

    24V Electrical Question

    There are many on eBay and Aliexpress but it can be hard finding one with an Australian power cord. Here's one on eBay that could do the trick for under $25.00. Edit: I'll add that the Chinese adapters can be a mixed bag with regards to reliability. Certainly there are quality manufacturers...

    Hi Guys, A quick update - I've been flat out setting up production for these puppies but dealing with some unexpected setbacks. Our PCBA substituted a few components that aren't working quite right and it looks like I'll need to order some replacement components from Digikey to do a proper job...

    BrewMonitor project

    "coz" is reason enough for some of us :blush: but the basic rationale is: Fermentation is super important. Like if you only do one thing right in your brew make sure you... sanitise. But if you get two things right, make sure your fermentation is good also. Yeast is sensitive to many factors...

    Hey vortex. Don't worry about "polluting" the thread, I feel your discussion is very relevant and we're all aiming for the same outcome. In fact I've learned so much from the feedback in this thread I'm very glad that I posted it up even if it's not all positive for the BrewMonitor project in...

    I must admit I still don't understand what rPi brings to the table over a photon. I fully understand if that's the technology stack you already know and love but IMO rPi is a little over the top for logging bytes and toggling IO. Hosting a web server locally is novel but old hat with all the...

    Hi, yes there's news! The membranes arrived this morning and we're putting together a couple of units today to validate the design. I found a minor bug in the firmware that I'd like to address and test before we ship anything but it should be sorted by the end of the week!

    USB microscope

    Try stick to 400x. I've found that anything higher and you can't fit the counting grids into view at once so just amke sure it supports 400x. That Braukaizer link is awesome. I also picked up a 10ml pipette, 1ml pipette and pi-pump at LabFriend.com.au and they are handy. Having USB would be a...

    Hey @professional_drunk, I'm still busy coding pushover and thingspeak integration today but I've also been thinking about your rf power sockets as an option for the future. Are these the kinds you used? They are surprisingly cheap at $13 bucks a piece!

    I thought the same at first but the idea is that we want to measure the change in weight of the wort, exclusive of the yeast. So if some of that wort mass is turning into yeast instead of alcohol then we need to account for that. This has also been covered on HBT forum but the good news is it's...
