Re: Timer DIY

Hi, I did - I did a dump of the transaction it performs and stared at it for a while but it doesn’t look like any serial protocol that I’m familiar with (which slid a few!) I’m going to build a test box that replicates what it does with an arduino / esp32 when I have some time and I’ll post the code...

Re: Timer DIY

Nice! Is that replacing the original main PCB completely then? I'd wondered about doing that to make things easier but haven't had much time recently... I'd also considered re-programming the PIC as that would be pretty easy to implement additional features such as PID control and a new I/O board w...

Re: Timer DIY

I'm working on a web-connected timer for my Spaz. I have a proof of concept working but should have something to show soon. My goal is to get out of this in the neighborhood of $50 and use as much existing platforms as possible (less time investment). Ah, interesting - how did you get on? Is yours ...

Re: alternative to Spaziale timer

I just ordered one of the above - Id been trying to find a La Spaz timer to snoop the hardware comms so I could replicate but this looks like a decent alternative option! I'll update my thread after it turns up and see if I can document whatever I can work out about the protocoland replicate with a ...

Re: Water temperature

Thanks for that Chas. Yep, it thinks temp is up at the set point. The probe is about £40 in the UK which is about 8 times more than the basic component cost (typical vendor mark up!) so was hoping to nail down the likelihood of its failure a bit more tightly before ordering one - P&P is pretty h...

Water temperature

Hiya, On my machine (Mini VII) somethings "not right" - the espresso tends to taste bitter and never quite feel right. I've looked at all the obvious things and can't see anything so I've started looking at temperature. My machine is set to 94 degrees, with an offset of +3. I've got my tru...

Mini steam boiler replacement

Hey all, I need to replace my boiler on my mini ; I’ve picked one up and looking at fitting it. Firstly, the fittings on the existing boiler appear to have a sealant or thread lock on some of the nuts / elbows. Can anyone advise what’s used? I’m guessing it’s a food safe thread lock? Secondly, are t...

Re: Timer DIY

Yep. Ive just had another look at it trying to work out what protocol it's using. I've ruled out a bunch of the obvious candidates now. It's a bit frustrating though as it would be a lot easier if I could find a timer to borrow and capture a two way conversation in process as I could replicate / emu...

Re: Timer DIY

This is a capture of the machine trying to talk from earlier - just need to work out what the protocol is and build something for it to talk to and see if there's anything obvious one can do!

Re: Timer DIY

Funnily enough I'd just been looking at mine when I saw this... I’m not familiar with the M5Stack – I’ll check it out. I had envisioned using a Global Cache iTach to deliver serial codes to the control board, https://www.globalcache.com/products/itach/wf2slspecs/ . That won't work I'm afraid - it's ...

Re: Timer DIY

Hey all, Thanks for the replies - so I'm an embedded systems engineer by trade and reverse engineering the protocol used should really be a pretty trivial matter if I can get one of the stock timer controllers to look at with my logic analyser. I'd expect that it's not doing anything glamorous and i...

Timer DIY

Heya, Has anyone properly looked at how to DIY a timer alternative? I searched the forum and a few people mentioned thinking that it uses a serial protocol - is it documented or has anyone tried reverse engineering it? I guess if there's anyone in the UK with a timer I could have a look at it wouldn...

Steam Boiler Terminal Covers

I guess it must also be common for others for the spade terminal boots to be trashed by heat on these. I did have a dig through the forums but couldn't see anyone with similar parts i.e. clip on covers that don't require the crimps removing. It looks like the JST CS-63N005 should do the job but befo...

Re: Machine tidy up...

Ah, I don’t think it’s that - the flowmeters I think should be < 5% error as there’s not much scope for error, I’m setting at 36ml but seeing repeated shots coming out at 40 - 80ml which is obvs a bit beyond that! If I do a shot without the PF attached puts out over 120ml - bit time seems pretty con...
