    Espresso under lights

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ive recently bought a semi auto Diadema Jnr and I want to find a way to illuminate the group area. Ive tried using a halogen desk lamp with a flexible neck and it does an admirable job but I was hoping to install some lighting in the body of the machine. LEDs and a transformer perhaps...? There seems to be a bit room up amongst the switch electrics. Im not exactly a technical wiz when it comes to all things electrical so feel free to dumb things down :) Ive found a fellow coffee lover that works at Jaycar so I might have to get his help...
    Let the suggestions flow. Any advice or tips would be much appreciated.

    Hey Sharkboy,

    Welcome to club Diadema!!! :D

    Hope you are happy with the unit, I love mine albeit with L Plates still attached....

    Have you considered using those mini neon tubes that Jaycar sell? They are tiny and would fit in that area where you can see all the wiring from underneath.

    I have no idea why you wish to light up the group area.. ??? But coming from a car cosmetics background, I think these little babies would suit your purpose.

    If not, you can always use led highlighters sold under the Aerpro name. They are 12Volt though...

    If you decide to go down the 12v path, PM me as I also have a business selling all these fancy coloured lights etc. for vehicle applications. 8)

    I was intending to change the colour of the bezel light for the power switch to blue, just to stop me accidently flicking that switch instead of the brew one....but seem to have naturally overcome that problem :)

    Regards,

    James

    Hi James,

    I think we should get keyrings and t-shirts made up :)
    "Dont be a weiner get a Diadema" or something else that rhymes with Diadema...
    My kitchen has only got a ceiling light in the center and whenever you do anything on the benches you tend to cast a shadow.
    I almost bought one of those notebook USB snake light things but while the Diadema is a great machine, it still doesnt have a USB port :(
    I really like being able to see the pour. Leds might be a bit blue...?
    Do you think transformer would survive in the body of a coffee machine?
    Ill head down to a Strathfield on my day off tomorrow.

    Re: Espresso under lights

    i got a bendy halogen lamp from ikea for $16. Sure i cant install it into my machine, but the globe is small enough to squeeze in near the group area and cast brilliant white light across the pour, and a little bit into the cup.

    I did this because my kitchen is like a cave - not a lot of natural light, and not the best cieling lights... its imporved my shots heaps! Im no longer running into blonding, i can see very clearly when its starting to reach the blonde stage, and i can stop the shot there.

    Move over Paul Bassett...

    coming soon to Foxtel:

    Pimp my espresso machine
    In this weeks show CSrs get the neon and doof-doof into the sleek stainless bodies of their coffee makers and mod a turbo blow-off valve to fit a Slivia. ;D

    Seriously though, even sewing machines have a neat little light that shines directly on the work area... you blokes might be onto something here!

    Re: Espresso under lights

    Ive been looking into moding my M-28 with some kind of a light for this exact reason. I see some of the newer high-end machines are now coming with a lights. It only makes sense. Especially with the larger home units and the vast majority of commercial units. On all of them the grouphead and surrounding framework directly overhang the shot area. The only way to get light on the pull is to either stand off to one side or have some sort of oblique lighting set-up. This has bothered me from day one with the M-28.

    Re: Espresso under lights

    Nice one Mal

    I think I looked at the lights you mentioned tonight at Jaycar. They came in varying lengths/sizes and colours although small and white is the only combination Im after mmmm green espresso :)
    My buddy at Jaycar was trying to put together a small LED light setup for me but the prototype is still under construction ie he didnt have time to do some soldering and heat shrinking :)
    I found some fish tank halogen lights. Theyre only 5W but they had 100W bulbs I could have put in :o They look kind of like giant christmas lights and only cost $20. Theres a transformer (chunky black boxy power plug thing) and two lights in a kind of Y shape setup, think stethoscope. They even come with suction cups that hold them on the side of the machine casing. Ive cobbled together an aluminium foil sort or light shield to direct the light. They run fairly hot so I only turn them on when Im making coffee. The light produced is more than adequate. Its great for observing the pour and looking for those first signs of blonding. Only downside so far is that the only way to turn the lights off is to unplug them, which is slightly annoying. Im sure it would be possible to install an off and on switch somewhere along the power cord like some bed lamps have but that goes way beyond my technical expertise.
    Chrome looks great lit up in a dark kitchen :D

    Re: Espresso under lights

    Hi,

    Im not sure how much room is available inside the case of a Diadema but if there is enough room to the right and left just behind the Group, a small CCFL (Cold Cathode Flourescent Light) might be the go. They can be obtained in a wide range of colours including more than one shade (temperature) of white.

    Most of them come with a small inverter thats intended to be plugged into a 12V DC power supply in a PC like these... http://www.pccasegear.com/prod1528.htm . You can also get 230V AC Inverters for them as well but you would have to do a bit of a search through the Jaycar, Altronics, DSE websites to locate one. The 230V AC Inverter is the best way to go as you wouldnt need a Transformer or PSU as required for the DC Inverter.

    The quality of light from a CCFL is excellent though and lamp life is typically rated as 20,000 Hrs and as the name implies, they run very cool. The PSU/Inverter hardware would have to be mounted low down in the case somewhere away from the heat of the boiler and out of harms way of water spills, etc. Worth looking at for high quality and accurate colour lighting.

    Cheers,
    Mal.

    Re: Espresso under lights

    Hi sharkboy,

    I guess I favour CCFL lighting because it comes in a very wide range of sizes, shapes, power output and has very accurate white light ranging from cool blue/whites through to warm yellow/whites and everything in between.

    You can get a much better range of fittings from a dedicated CCFL supplier rather than buy from a PC Mod Shop or similar and most likely a 230V AC Inverter to suit as well.

    Quartz-Halogen lighting is pretty good too but because of its power hungry nature and short bulb life compared to CCFL, it works out a lot more expensive in the end. Youve also got to be careful to make sure that you dont "mismatch" QH bulbs for the rating of the light fitting and the transformer... put too large a rated bulb in there and before you know it, lots of blue and white very expensive smoke.

    A typical 150mm x 6mm CCFL Daylight White kit on the other hand, would only cost about $15-$20 all up including Inverter. You can also get a range of Circular CCFL tubes too covering a wide range of sizes and Diameters and maybe something like this would be more suitable.... could mount on the case around the Group Shroud for even lighting all around.

    Anyway, I guess whatever options might ultimately look the best to use, it will come down to what is the most simple and straight forward to fit and wire-up. You never know, might be able to con errr, I mean ask a sparky to do the job for you in return for supplying him/her with some great coffee. After all, who could refuse that offer? Hope you find something that works out and looks the part, all the best,

    Mal.

    Re: Espresso under lights

    Ill take a closer look at CCFL lighting Mal. I like the idea of a round fitting. Are they fairly bright? The lights I saw tonight were on a display board featuring sizes and colours, but it was hard to tell how much light they were putting out.

    Re: Espresso under lights

    Hey guys!

    Sharkboy, my mistake initially... :-[ I was referring to these CCFL lights and called them neons.

    My biggest issue with these is that the Diademas have a couple of small holes on the underside of the cover and Im not sure that enough light will shine through to be of any benefit. I have installed a number of neon lights into rear bumper bars to illuminate the number plates and have found this to be the case.

    O.K., slightly different application here....but the principle is the same. Having a closer look at my machine last night, I think that your $20 solution is going to be the most effective.

    I will have a hunt around the auto catalogs to see If I can come up with a better idea - as Andy mentioned "We may be onto someting here!"

    Re: Espresso under lights

    So who has the building specs for a silvia? Is there room to safely squeeze an operation light in the plate the group heads sqeezes through? :P I think today at the MLB CS get-together we talked about everything but this. Mind you I was late, I went to scope out the Northcote cafe by accident, still it was a nice day for a drive. ;D

    Re: Espresso under lights

    Now tell the truth Boris. Youre just a spy on the Vittoria payroll arent you.... We all know that you got lost on the way to Pellegrinis ;D.

    Now on a serious note, thanks to all for turning up....nothing like chewing the fat about good coffee whilst drinking coffee! I hope that bg&d can be involved in more of these....

    Hi Stephen,

    Yep, they are quite bright.... in the order of brightness the way a standard flouro is to a standard incandescent lamp.

    Re: Espresso under lights

    I still cant believe the Diadema doesnt come with a light. I know the Silvia is at the lower end of the prosumer market, but at least they offer a light as an optional extra (TIC). ;)

    Bit like those BMWs that dont have the indicators hooked up I guess. ;D

    AJcafe, the offer stands, and Ill throw in a torch!!

    Yeah- unbelievable. I was flabbergasted to note that neither leather or sat. nav. were on the options list for my machine. :o. Good thing it had a cd stacker...or the deal would have been off *;D

    They told me mine had cruise control with remote. I think they gave me the wrong remote though as every time I click it the neighbors lights go off. They were getting rather upset so I had to stop experimenting. ;D
