Enclosures

Kicking off ART-TRONICS’ line of custom enclosures are the cases for the G3020 and G40 for Genesis Radio. Assembly instructions can be found here.

More to come, enjoy!

    Hey Case Mates,

    Here is a great source for case fans. The G3020/G40 case has 11mm clearance between the case top and the heat sink so 10mm fans are what you’re looking for at OXOIDE.

    and one in particular::

    Enjoy!

    Hey Rob, When are we going to see either decals or some other means
    of marking the jacks and switches of these boxes?

    Tom,

    That’s a great question. Because this is a custom kit I would not have any idea what functions folks would be assigning to the various holes, sockets and switches. I’m sure there is a consensus but it was not really apparent on the forum so I took my best shot at providing the minimum holes that appeared on most of the photos there. And – this radio is a kit and assumes some level of “tinkering” at least with labeling anyway.

    So since manufacturing is a “bulk” activity I would not be able to supply custom labels and even if I could – they would be prohibitively expensive.

    That said, it is kind of an interesting idea and I will see if I can come up with a strategy that would allow you to fill out an online form that would allow you to print them out on your printer on clear sticky acetate (you can get that at Staples, OfficeMax or Joanne Fabrics) and then cut that out and adhere it to your faceplate. How does that sound? At least until we have some uniformity on the layout and then I will investigate what we spoke about on the phone about having etched plastic face plates made. But, again, we need some volume.

    Thanks for the great feedback!

    G40 Builders

    I queried Nick about the need for support of the board using the center hole seeing as it’s supported by the front an rear panels so firmly. He suggested, as an alternative, using one or more pieces of non-conductive foam – ( black 1/4″ +/- thick) to support board in the center if you really think it needs additional support. Though there is no documented reason for it.

    If you’re a “kitter” like me and you save everything, you probably have a few chunks of that black foam left over from static sensitive components. Let me know how that works if anyone tries it.

    Hey Rob, I really like the plastic etch plate like we
    Spoke on the phone of. However, if there is no
    demand, then your idea of using a sticky to paste
    on the end plates appeals to me. I couldn’t either
    write small enough or neat to make it look nice.

    Tom,

    Now that the kits are all shipped and I have some time, I’ll jump back on that labeling idea. I had most of a prototype app done but got sidetracked there.

    I’ll keep you posted.

    A note about the Rotator Switch punch-out location.

    Several people have commented that they were disappointed that the location of the rotator switch required using a miniature or subminiature rotator switch to dodge the internal capacitor that is in the way. Their complaint was that if the hole was 3/8 of an inch to the right it would clear it and allow the use of the standard 1″ switch which is only a couple of bucks as opposed to $20 for the miniature or sub.

    Here are my thoughts and observations on that:

    1) Location Issue:: If you do move the hole 3/8 to the right there would not be enough room to label the positions at a size that would actually be legible. I have verified this by doing so and printing it out to scale.

    2) Cost of smaller switch issue. That’s even simpler – you paid $150 + for the radio and $70 for the case for a total of $220. So I don’t think that $20 represents an unreasonable percentage of that total cost to achieve a perfect control panel layout.

    3) Only the G3020 has the above issue so making the least expensive enclosure to cover the majority of the benefits seemed the most practical thing to do given that I had to have a minimum run of 20 with no variations.

    4) I could have added yet another 1/4″ to the original intended height of the case which I wanted to keep as small as practically possible. I did that once and it added $10 in material and cutting costs to each case (I paid for that one since the price had been announced already) – so to accommodate the switch by moving it vertically to clear the cap, but still allowing said labeling advantage, would have been another $10 for a total of – you guessed it – $20 added to the case. Hmmm! That looks like a wash!

    5) There were no pre-existing recommendations from the manufacturer or statistics on where the average user would want to position the front panel components so I made a logical guess – I copied the ones that seemed to be the most prevalent! (and the most copied, in turn).

    In end these points are not meant to rationalize but to bring some clarity to the reality of the situation. Now if someone wants to have a perfect custom case designed and has a spare $700 I’d be glad to accommodate!

    I do plan to have some blank panels made up during the second run which will only have the through-holes for the PC board jacks pre-drilled. Then the user can do the others. I will announce when they are available on the Genesis Radio forum.

    My Question to Tasa – the designer of the Genesis Series::

    Hi Tasa,

    I have a question about the capacitor on the G3020 kit that is adjacent to the Audio Out jack (see attached photo for detail). Is it possible to mount that cap at an angle, with longer leads (maybe put some shrink wrap on them for insulation) so that it can be bent aside to avoid the switch body?

    It would be great if it can be bent slightly out of the way so that a 1″ diam. rotary switch can be used. Right now if the builder has already put it in it is not possible to use the standard rotary switch as that cap is in the way. Smaller rotary switches cost from $12 to $45 so that’s kind of prohibitive.

    On the newest run of enclosures I have moved the switch hole over to the right 1/4″ so that it is less of a problem but the cap will still have to be mounted a a slight angle but much less.

    Also I have one person that has ordered an enclosure that he wants to use with his G80. Is that kit based on the G3020 board? Are all the PC jacks and mounting holes in the same place as the G3020? Will he also need to use a rotary switch for band switching?

    Thanks for your consideration.

    Tasa’s Answer::

    Hi Bob,

    Thank for nice job you done with enclosures for Genesis KIT. Yes it is possibel to do what you are suggesting to put this ELCO in horizontal position with longer legs!
    The G80 is mechanicaly the same as G3020 the difference is only in some component values!
