    Rocky Switch mod - would it be easy?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    One thing I hate about my Rocky is having to hold the switch while I grind. Would it be possible/easy to bypass this switch so that it is always on so that I can just use the switch on the side? Alternatively, (and preferable so I could turn it off with my left hand), could I replace the front switch with an on/off type switch? Is it possible to find such a switch that would look good on the rocky? Has this mod been done before?

    TIA

    Hi tintub,

    As always with things electrical, best to get an electrician involved in the modification.
    I havent heard of it being done before, and I dont mind the standard arrangement, however, I cant see any reason why it woldnt be possible, and you should be able to get a suitable switch if you look around in electronics stores and/or electrical wholesale outlets, again electrician probably could help locate the right part if he/she was interested, (cos you need switch of suitable rated voltage and current).

    Another option you might consider is fitting a switch nearer the spout, so that you can activate it with the portafilter itself, as is done on some other grinders....

    Just my 5c worth

    Hi tintub,

    Basically, what Bullit has said is right on the money.... you should get an electrician to look at doing this for you. Since these switches are a standard DIN size, it should be possible for a sparky to get a suitable replacement for you that looks identical to the original but with the toggle operation that you are seeking. Try your local sparky first and see how you go :)..... All the best,

    Mal.

    Re: Rocky Switch mod - would it be easy?

    Thanks... I had another thought and that would be to rewire the switches so that they work in parallel rather than in series. That would mean that I have the switch on the right to do the main grunt of the fill, and then can top up with the front left. This is probably the easiest way around it, as it would just be a matter of rewiring and I wouldnt need to put a new switch in... but I think I would prefer replacing the switch with a normal toggle switch...

    Would Jaycar do this kind of thing or do they just sell components?

    Gday Tintub,
    Jaycar only sell components, they wont modify your grinder for you.
    I can see one slight problem with having the switches in parallel. You said in your original post that you wanted to have a left handed operation, youll have to swap hands whilst grinding if you wire the switches like that. The right hand to turn the main switch on/off and the left for the momentary activation.
    You should be able to get a drop in replacement switch from Jaycar, just measure the original front switch and make sure that the replacement switch has the same rating. The cutout for the switch is 32mm x 12mm.
    Standard warnings apply about turning the power off before sticking your hand inside *:).

    I did this mod.

    I pulled mine apart swapped the switches - left the side one out of the series and now i have an on/off at the front.

    i was aprehensive but my old man was their and he is electrickery minded and he said it was no probs. it works a treat.

    the electrician comments a slightly wrong. most sparkies only deal with mains power up to the wall socket. what you want is a Technician, ie someone who repair tvs microwaves stereo equipment etc. i have quite a few sparkie mates that i know would have no idea when it come to electronics. a sparkie is a upgraded plummer.

    I bought a white on/off rocky replacement switch and just switched out the front switch. It looks like a bought one and the switch just pulls out with carefu. Levering so you can accesscthe spade connectors. The mod took 30 seconds and was $14 well spent.

    You know this how?

    From the same source as your grammar and spelling source no doubt.... ::)

    Making comments about professions is uncalled for. Electricians will specialise in whatever field they choose, but this will not make them a true expert in all aspects of their profession. Working in the mining and construction fields certainly rewards them better financially than in some appliance repair careers. Sometimes a technician is just someone with a love and understanding for what they choose to do. It is more important to seek suitably qualified people with experience and passion in their field.
    If you start making a hierarchy of "Trades", be prepared to be consigned to the bottom of the heap by the Engineers, Consultants and many others with years of experience and qualifications under their belts. A good command of the English language is a great place to start.
    A wise person will admit they can always learn something new. Is that not one of the pleasures of life?
    Out of interest, how does one upgrade a plummer and get a "sparkie" as the result?

    The mod should be fine as ling as there is no voltage regulation provided by the switch array. If that is the case then you would be able to bypas the switch at the front and run solely of the side power switch.

    Without knowing the internals of the rocky i cant say this for sure but I have just done somewhat the same thing with my Cunill.

    If you can get in touch with the National Distributor (Grinders Coffee) then you should be able to ask their technical team if the motor in the rocky needs any voltage regulation.

    I hope this helps.

    would be cooler if you could rig up a infrared sensor that recognized when a PF is there and turns on automatically. Then you could add a time delay switch to it thats adjustable using a dial I had a laugh :o 8-) :D

    It would take a bit of work but here is a start for you http://tiny.cc/aeeuk. From what I can tell you would need to provide voltage regulation to the switch though as I dont think it would handle 10A.

    Scrap that last idea.

    RFID (Radio Frequency Identification). You could set up an RFID sensor that runs to a timing board. Depending on the ID it recieves, it would be possible to activate the timing board for a different amunt of time, say 1 ID for your single basket, 1 for your double and 1 for your 18g bottemless.

    The by wiring a pressure sensitive bypass switch you would be able to grind extra at the swipe of a sensor pad.

    If only we had some engineery types to help with the design of the timing board (hint, hint! Anyone?).

    If you want to go these lengths and maybe add even more flexibility, why not scan through all of the Arduino projects. Several could be adapted for the sort of thing youre talking about.... ;)
