I’m adding your addresses to a contact list this time. In the future you don’t need to PM/DM me your address if I’ve previously sent you something and your address didn’t change.
We’re going to include a “free gift” with these boards, but I don’t know exactly how many we have so it might make it to everyone.
Please don’t forget a phone number which is required for our dirt cheap and fast logistics channels even if it makes no sense in the context of your country. Someone in the US wrote to say that the last mile carrier was Amazon instead of USPS, here in NL it is usually DHL which generally likes a number. We don’t have any control over this, but also we don’t check the numbers validity if that is an issue
If you could add me to the list, that’d be great. I think you have all my contact info (no changes in years). Pity about the mask removal by the board house.
For next batch, to better highlight the lines on the back referring to the outside (GND) circle (vs. the inner via ring), maybe offset the lines so they would only pass through the outer (GND) rings?
Small visual change, but I think it might improve the clarity with only a trivial one-time engineering cost!
Photographer didn’t quite finish the photo today, but I imagine these will go up in the store tomorrow.
If you requested a sample it is already in the mail, or will be tomorrow, depending on the logistic provider we used (pickup scheduling is a bit weird at the moment). (@AreYouLoco , @kd7eir , @mbrugman@masterX244 , @grymoire , @henrygab )
If you did not request a sample, I will post a coupon code here for a free set that can be used in the (new) store. You will need to pay for shipping though. I believe there are 13 prototypes left.
Thanks for checking this one out! I’m going to use the initial green prototypes to make test devices for verifying every protocol mode
Blank plank prototypes are now at shop.BusPirate.com, though we don’t know if the store is fully working. For your patience helping test the new store, you can use coupon code BLANKPLANKREV0 to get a blank plank set for free. Shop is broken and I disabled checkout. Someone will look at it tomorrow.
I started working on the blank plank soldering. It’s, uh, something…
I’m using some through hole and some SMD components. Kinda sketchy for me to do PTH stuff without catching that annular ring for ground. Best cases, I’m still seeing something like 60M Ohm to ground on anything I solder that way. I guess it’s just a matter of practice (that’s on things I don’t want connected to the ground ring)
I’ve been doing more as I go. It’s just a new concept for me, I guess. Just bothering me that I’m having trouble with not completely isolating PTH stuff from hitting ground.
For through-hole I like a ton of flux to keep everything flowing smoothly. There are also tips on the proto pattern github like keeping the iron temperature a bit lower than normal so bridging is easier on the top layer, etc.
I scaled way back on what I was planning to put in the plank for now., but at least I got it to the point where it will work for what I need. I’ll add more later.
I’ve done a lot of through hole and SMD over the last 40-ish years, and maybe I’m just being a codger, but I think I’ll stick to plain proto board/perf board in the future.
Strange, I never had the issue of having a measurable resistance to ground with THT stuff (that is without getting out the picoammeter). Could maybe be flux residue?
Just to confirm that, you could clean the board with flux cleaner and measure again.
But otherwise, yes, you have to dose the amount of solder a bit with THT parts to not bridge the gap. But I find the convenience of easily being able to get a good ground on every hole by far outweighs that.
Cleaning the board took care of most of the leakage issues. I reworked the joints that still showed leakage until they were all good. I was measuring with a fluke 87; nothing fancy.
I really love the idea of being about quickly prototype with SMD and PTH on one board.
Maybe I’ve just done too much prototyping with wire wrap and perf board. This took much longer than I expected and I just kind of gave up on some of what I had planned.
This is just my personal experience, I’m sure there are many others out there that have had great experiences and success.
When mine arrives I will just make simple JTAG adapter for the target board so its easy to just hook up, connect and reuse without fiddling with wires. The problem is that the target board requires some CPU definition. And thats way too much low-level stuff. But there is similar CPU described and I will just find time to write it with Hardware Manual for that CPU.
My program of choice will be UrJTAG that is compatible with DirtyJTAG firmware @ian dropped recently. So good way to test that out. At least thats the plan.
If you are more used to using wire wrap, you could probably mix the different styles. Like doing most of the longer-distance connections with wire wrap and use solder blobs just for stuff that is nearby. Or not use proper wire-wrap, but burn the isolation of the wire wrap wire and solder it.
I meant both wire wrap and soldering wires on perf board. Depends on the application; but I know what you mean. Sometimes if I had more time or had to do more than a could of something, I’d etch a copper clad boards. I guess the point is that I’ve done a lot of different types of prototyping.
I really don’t want to talk bad about the concept; it’s just not for me. As I said, I love the concept behind it.
