  1. @luvdunhill - I think there are certain autodesk products that you can get an education (free) license for that would be useful for you.  I'm spoiled and have access thru work so it's never really been a thing that I paid a whole lot of attention to. That said, I got your sketch and if time permits I'll try to turn it into a dxf tomorrow at work and see how the laser reacts to it. The challenge (for me) will be figuring out how to program the combined cutting/etching operations into a single program so that it does it all at once and there's no (or at least less) chance that centers get misaligned.

    Question for those with CNC thingys:

    i have a project where I would like to create a translucent dial. Something like rigid paper or plastic with a velum look. I need to put some markings on it, a scale from 0 to 100mA. 

    How would you approach this? It would be less than a few inches in diameter and a kidney shape. So, I would need a method that could also cut out a complex shape. I also wasn’t sure how well CNC could ink? If not ink, a very thin line could work, perhaps not even all the way through the material - like an etching.

    Of course I just need like two, so that’s a factor as well.

    I'm pretty sure that I could do this for you on the Dremel Digilab that I have access to.  Give me a dimensioned drawing of what you want and I might have some scrap plexy that we could try out first before.  I should warn you, it might take me a while to get to it. I'm like Mikhail-levels of slow these days in getting projects. done. 

    Speaking of project, COVID speaker project #2 is nearly complete.

  3. I know this will be very un-HC of me, but balanced DAC's have generally been more trouble than they are worth for me, especially when used with a balanced amp.  It really comes down to what headphones you are driving and how much voltage swing you need, how much gain your amp has, and what sort of attenuator you're working with. If you get a hot source, with a high gain amp (I know the GSX has a switch), and sensitive cans you may just drive yourself crazy (pun intended).  So careful what you wish/ask for and best of luck in your search.

  4. Tip for the future - in situations like that look to flip the larger component on the bottom of the board.  As long as you are using standoffs that will allow for clearance to the chassis it ends up with less of a cramped situation and the potential for leads to get closer to things than you would like.

  5. Once again this year I'm prepping to ride a century in support of the Kelly Brush Foundation.  I have (quite literally) been training my ass off and started the year with a goal of riding more than 2,020 (get it?) miles before the event.  Well, I've truly exceeded that and am currently sitting at ~2,300 with a few more weeks to go before the ride.  Of course, as most things have gone in 2020, this year's event will be quite different from the past with no formal large gathering in VT.  So the group of us that have done events like this for the last 10 years are going to get together and ride a socially distant event all the same.  

    For those that don't know, the Kelly Brush Foundation is a non-profit organization dedicated to assisting individuals with spinal cord injuries in finding ways to get out and enjoy an active lifestyle.  For me, this is a cause close to my heart.  I love the outdoors and the freedom to explore it in a variety of ways and have worked with organizations like the KBF for the last twenty years to help others do the same.   

    The mission remains the same, regardless of complications of life, so I'm trying to raise a bunch of money again this year with a goal of $2,020.  As usual, all of the donations are tax deductible although the great pumpkin has made less meaningful than it used to be.  Like past years I'm looking for interesting ways to sweeten the pot if you open your wallet a little bit.  I've got something fun in mind for anyone that donates $100 or more, more to follow on that.  But for now, here's the link to my personal fund raising page - https://kbf.akaraisin.com/kellybrushride2020/2b87af6c62214f81909ae4e7b306384e.

    Any donation large or small is very much appreciated.

  6. Here's a tip that I got from a friend that is a butcher, grills are pretty terrible for cooking steaks unless you like them really rare.  I have not used my grill to completely cook a steak for several years now. The current process, which came from the butcher friend, is to sear both sides of the steak on a very hot grill for 2-3 min a side.  Then transfer to the oven (in a pan) at 225F-250F and finish to desired internal temp, generally pulling 5F early and letting the steak rest for 10 minutes or so before serving. 

    For burgers I religiously do the following - burgers are to be flipped once and never pressed. Cook them until they bleed up thru the top, then flip and cook and hope that the flames don't get too bad. 

    That's my 2c anyway. 

    Oh one more thing, the Egg can absolutely be a "proper smoker" - more so than my Traeger according to the die hards. It'll take more effort, and potentially a gadget or two to get consistent low temps for long cooks (for example) but there are a ton of folks that swear by them.
