    HeatSnob - on a Mac

    Hi, I'm considering getting one of these for my corretto setup, but the only old laptop I have is a macbook. Has anyone tried using heatsnob with a mac, and if so how did it go? I'm pretty good with computers, and could easily build something cheap but would rather spend that extra money experimenting with more green beans as opposed to computer hardware.

    You’ll need to run parralels or some other emulators. Or install windows on the MacBook

    virtualbox is open source and super-easy to set up - runs the guest OS as a program window. you'll need a disk image of whatever version windows you want to install - downloadable from the microsoft website. i currently have windows 8 running on my macbook. trying to open roastmonitor results in the error message 'no meters found' so i assume that once i plug in the heatsnob, it'll be fine and dandy (just ordered it from beanbay). i'll confirm in a couple of days once the hardware arrives.

    I would be really keen to know how it goes. Good luck!

    got the heatsnob today. it's a lot smaller and lighter than i thought! and yet very sturdy!

    took a couple of minutes getting windows to recognise the thermocouple, as the mac reserves the disk drives before virtualbox (even though virtualbox recognises them - it just greys them out so they're unclickable)...but the thermocouple doesn't even register on the mac, so couldn't find an option to disconnect as i would for a thumb drive. but after adding the heatsnob as an option in virtualbox's 'ports' setting, and re-connecting it, it recognises straightaway. got it running fine now! looking forward to hooking it all up and having a play!

    Good stuff woodhouse. I had a look at Virtualbox, looks really good and its free so thats a big bonus. Did you enable USB controllers from the setup menu of Virtualbox?

    i did it from the bottom right of the virtual machine. there's a USB icon in the middle.

    (moved these posts here to it's own HeatSnob on a Mac" thread)

    The "shorted to power" error that you can see means that the USB on your McThingy is "leaking" power to the earth side of the USB. Typically caused by a badly designed plug-pack which will amplify any noise on your power circuit.

    Likey something in your house on that circuit is noisy. On mine (on a PC notebook) it's fine except when the 3 phase air compressor comes on it will spike and then again when it goes off.

    Try unplugging your mac from the power point, I think the graph will clean-up.

    laptop was always unplugged. i noticed that the probe was getting knocked around on the vanes the first time, so i've adjusted that. the graph has cleaned up a little so i can follow what's going on, but it's still very messy.

    I have been playing with a new HeatSnob with two probes. I find one of them gives a lot of shorting faults. The readings when it reports a shorting fault are quite different to the reading where there is no fault. You might find a different probe solves the problem.
