Any recs for a hot air rework gun/kit, cheap? Looking at some of them on eBay. It won’t get a ton of use so no need for a really good one, just something to get the job done. Sent from my iPhone using Tapatalk

Glad to hear John! We'll have to get together soon so I can get your remote back to you.

And who are you? Very cool Jose!

Happy Birthday!

Happy Holidays to all! I hope 2018 can only be better than that thing called 2017

Happy Birthday Ken!

"More than 20,000 people have been using our product" And 100 billion flies eat shit... your point is?

The outlines are in 21 tPlace in Eagle (where they should be). They are in the top silk layer in Diptrace (and not the top assy layer). The parts appear correctly in the Preview in Diptrace. A person from SeeedStudio replied in an email not to worry. The gerber viewer sometimes has issues. Sent from my iPhone using Tapatalk

Guess I should look at the neg regs datasheet. If the pads are all connected together on the board, the solder bridges on those pins won't hurt anything.

It shouldn't unless you decide you wanted to change voltages.

Sorry to dredge up an old topic. I have started using DIptrace again (3.2.0.1), and am getting along with it (more or less). However, when generating Gerbers, some of the top silk is not appearing when using gerber viewers such as the one on SeeedStudio's site (or gerber-viewer.easyeda, which appears to be the same engine). Specifically, electrolytic cap outlines aren't shown. If I view the gerber file in some other gerber viewers (gerber-viewer.com or CircuitPeople's) they appear OK. Viewing much of the same board, done in Eagle, appears fine. Any thoughts? I imported the schematic and parts libraries from Eagle, but did the layout in DIptrace. The parts in question did come from an Eagle library, but replacing one of the caps with one from Diptrace didn't seem to solve the problem. Some pics: This is a gerber from Eagle, on seeedstudio's gerber viewer This is a similar board, only from Diptrace: And finally, the same board from Diptrace, but this time using gerber-viewer.com

They aren't nearly as good about this stuff as they used to be. They offer next day shipping as a carrot, and then take 3-4 days to ship the order. My last order, I called and spoke to one of their reps and asked why an order submitted on the weekend had not shipped by late Monday. This was an $80 order. The rep said "with a large order like yours...". Precious, but I told her it was a small order, and that their commercial clients, etc. (and peeps like Doug) place much larger orders than that. Now they did immediately ship the part I got them to add to the order...

I think you meant XLR inputs, not outputs? You could just wire the XLRs and use the Neutrik adapters, saving yourself the switch and the wiring of it.

Very nice Jose! I take it that is input switching back by the jacks? Is the other PSU back by the transformer for a momentary power switch, or is that just for the input switching? It looks like some thought went into this layout and good job on the wire routing, etc.

Took a look at the dwg file tonight using Fusion 360 and also the SolidWorks eDrawings app. One thing I noticed is the corner blocks don't seem to show drilled/tapped holes on them. When I look at in the SolidWorks app, there is some Chinese writing (I presume), which of course I can't read. Are these instructions to whoever is making the parts for you? Here's a screenshot from the Solidworks app:

Thanks! I actually have Fusion360 on my Mac but haven’t spent the time to learn how to use it yet. Any recs on tutorials for that would be helpful. I’ve never used any CAD type programs... closest would be things like Eagle, etc. Sent from my iPhone using Tapatalk

It would be interesting to see builds from a voltage/biasing R value/heat perspective including whether using onboard vs. external regs. Sent from my iPhone using Tapatalk

Astro sent the .dwg file for the case to me, seeing if I can post it here... it looks like it worked. I don't have autocad or anything else on my Mac to open it (suggestions welcome). Dynalo.dwg.zip

I think luvdunhill has sourced pins for some Stax jacks before as well. Can’t remember where though. Sent from my iPhone using Tapatalk

Quoted the wrong post above. This person sounds like they know what they are doing in soldering packages like this. Sent from my iPhone using Tapatalk

Had the wrong post linked in my previous reply. This person sounds like they know what they are gliding with packages like the regulators use... Sent from my iPhone using Tapatalk

Also, regarding regulators, it would seem that the Amb-style externals with heatsink (U5, U7) would have a thermal advantage over on-board mounting (U2, U3) of these? Or is this an incorrect assumption for those of you who have built one or more of these?

Interesting, and sorry to chop out your casing pics I was looking at the KSC/KSA, then saw reference to the KSA1015 being the actual complement to the KSC1815. Then it dawned on me... are these the same as the Toshiba 2SA1015/2SC1815 that Kevin used to use in the Dynalo? If so, I've got some of these and may try them. The KSC1815 appears to be problematic to get in the same grade as the 992 which would make matching nearly impossible.

Ahh, good to know. I'll take them off my list then. I wonder if places like Handmade Electronics, etc. are still selling the older production?
