Soooooo much stuff came in yesterday and today. Received my Mouser order full of mostly SMD parts, a bunch of diffused RGB, pink, and bi-color (red/blue) LED’s from ebay (not in picture,) and my order from Arrow with a few SMD chips.

Can someone please explain to me why Arrow would use these hard plastic trays for ONE STM chip? I had two giant boxes arrive full of these trays. I don’t understand why they wouldn’t just box them in foam like Mouser does. Seems like a huge waste of money for a $3 to $5 chip.

Now what to do with the trays :thinking:

I think the answer is probably along the lines that they have a machine that picks an arbitrary number of chips and puts them in a tray and you will get your single chip in a tray and like it dammit.

One is a number.

A noisey ciat-lonbarde circuit translated to pcb by a member of a different forum that I belong to.

Now that Dud isn’t finishing a module every day, you’re keeping us jealous with all your recent acquisitions.

instead of trashing it they repurposed it , sent it to you to deal with .

A neat little ABS enclosure for my new Mean Well RT-65B switching power supply. Shown here with the power supply trying its new coat on for size.

Of course I haven’t yet checked the air flow requirements, but there may be a lot of drilling in my immediate future. The main reason for the enclosure is to keep the 240V power supply away from the various items of wetware infesting the environment. People, dogs, that kind of nuisance.

Edit: the late post brought this, a tape of thirty BAT54S, a SMT dual Schottky diode used as a voltage limiter in situations where we really don’t want the output to stray outside two strict bounds. This appears in the late stage of the CV In conversion circuits of Bela Salt, just before the result is fed into the ADC of the computer.

And I’m still in bed. Yesterday and last night were rough.

I needed more bus boards. I had previously had the same design manufactured but got them in yellow this time. I’m thinking I’ll put five or six of them up for sale soon. Trying to decide if I should offer them built or just the board. I also got five micro Ornament and Crime boards.

Nice, if you don’t have plans for all five O&Cs I might, uh, know a guy who might be interested…

Can’t tell, is that the original layout or the 8HP version?

2 Likes

It’s the 8HP version. Pretty dense and the DAC is $10-$15 alone + the Teensy. So, I will probably have one to spare :slight_smile:

yuh - would love a ÎźOC as well.

For my next case ( what am I talking about, the 2nd is only half full ?! ), I’d like to use bus boards as well. Given that I’m Jurop, it it probably best to order pcb’s myself (given transport costs etc). Are you sharing the PCB design files / where can I find the necessary design files to do so?

2 Likes

I modified a design from https://github.com/ThisIsNotRocketScience/Eurorack-Modules/tree/master/RobGould. I imported it into JLCPCB’s EasyEDA and labeled things better. I’m happy to share my updated Gerbers or you could customize it to your own liking.

Yours look good. If you could share them that would be great!

I forked the repository and added Gerbers and EasyEDA production files to https://github.com/cbloch/Eurorack-Modules/tree/master/RobGould/PowerBus%20Production%20Files

Just like in college, speakers that are too big for my desk. Delivered on a Sunday no less!



Now I need to build or buy some support. I could do extensions to the desk to save space I guess.
This is why you shouldn’t watch mixing/mastering videos on Youtube. Some dude in a red shirt with an alluring Italian accent makes an off-hand comment about driver size and the next thing you know you’re buying the audio equivalent of a Hummer. My first mixer was a Mackie so I’m pretty confident in the quality.

A piece of plywood is a pretty handy way to make a desk bigger (if it’s a sturdy desk). I’m thinking of making a custom desktop as well and trying to work out what I want in terms of size and handy features. I’m thinking cable management in the back is a must and maybe some way to hang patch cables on the front or sides.

Driver Size???

I just sold a pair of JBL TWIN 18’s Sub Cabs to a Guy. Dropped them off yesterday. They were for his Hi-Fi!!! (and no he did not live in a mansion )
