Time to toss the Ferric Chloride, well almost, It's still the way to go for a quick and dirty pcb. I'll be placing an order as well. Thanks for taking the time to do the gerber files. I really enjoy my daily dose of IMSAI Guy with the days first cup of coffee.
My five boards came in the mail today from JLCPCB. They look fantastic! I'm looking forward to using them. I was worried that the V-grooves would be omitted from the boards but they were all in place so it will be easy to snap the individual boards apart. I did try ordering through PCBWay but for reasons that I could not determine the quote kept coming back as $131. PCBWay is an excellent service and prior orders have gone without a hitch but in this particular case no matter how much I tried to tweak the order, including selecting slowest, cheapest shipping, it kept coming back costing a fortune. JLCPCB for the win at $19! Thank you once again IMSAI for sharing your projects. Sourcing parts for your projects can be a challenge but so far it's all turned out well. Especially those Lorenz attractor boards!
You've inspired me. I'm going to create some of these boards myself. I've never used a service like PCBWay, but I'll check them out via your link. Love your videos, and creativity. Thank you.
@@joeteejoetee I'm currently above the free shipping threshold with my digikey shopping cart and I'm about to finally order 500 of those bad boys for $10.

It might be a good idea to repeat the same pads and tracks on the other side of the PCB. That way, if you lift a pad or damage one side, you can still use the other side rather than throwing it out.
V grove is also done with a V wheel. For a 6 layer design for a miniature telemetry transmitter , inner layers 3,4 had power and programming connections, layer 1,2, 5,6 V groved, the transmitter portion would be potted into a pocket, then gain and frequency would be programmed, unpotted portion would be snapped off. The final product would be installed into compressor of a jet engine, running up to 40,000RPM, cooled with liquid nitrogen, with a static load of >100,000g.
You can get twice the number of pins per inch by using tenth inch dual headers. The board fits reasonably between the two rows of pins. This can give noticeably higher packing density, plus allowing plug-in modules for troubleshooting convenience.
Nice. This looks like a great way to deal with SMD parts for experimenting with a breadboard. The pins are thin so should go in and out of the breadboard easily. I soldered two strips of square header pins onto my Arduino Nano and now the Arduino is permanently mounted on a breadboard since the 30 pins fit tightly and make it almost impossible to remove. But that's ok. It is now my Arduino board. If you do this think about how you want it mounted before you press it into the breadboard.
Thanks for the inspiration, i like it... I'm thinking about drawing something like this myself based on my own ideas or for special components. One question, how thick are the boards so that the connections fit well?
TRUE! I use Gold machine-pin Male-2-Male connector strips. I buy the strips with different diameter pins, so I can choose between the outward facing connector diameter for Proto-Boards or matching Gold Female sockets later.
These may also work well, can't post a link but can be searched on Ama "Pin Header Strip for Arduino Gpio 40 pin x 10pcs Male Headers Pins Rignt Angle 90 Degrees Single Row Gold Plated Pitch 2.54mm 0.1 inch Breakaway for PCB Connector Machine Breadboard"
IMSAI GUY, did you include schematics for the two OpAmp boards? I can't locate them, although they flashed by in the 2of3 video. Are they available? I have learned a great deal from your videos, even for an old guy. Please let me know if I missed them in the post.

I don't get it. When I add this project to my PCBWay cart it starts out with an estimated cost of around $30. But after review the actual cost shoots up to $131! What's happening? Am I ordering it wrong? Is there something I need to change to get it back down to $30? Or does it actually cost well over one hundred dollars to have this project manufactured?

*checks description* "Pins available on Digikey and Mouser"
HOLY HELL, those are handy. Will order a bunch, THANKS SO MUCH
Did you order? PCBway is charging $131 for this project. HOLY HELL! Not so handy.
I bought 500 (!!!) of them from DigiKey and the shipping cost more than 500 parts !!!

Looks like a good and inexpensive way to do an edge connector.

Very nice looking boards. I make mine at home, which is very satisfying too.
What a great job. Thanks. I'm thinking of starting a subscription to PCBWay for your boards 😁

That's not breadboard compatible, which was the goal here FWIW.

You can poke something underneath (I usually use the back of my tweezers) and carefully lever it up.
@@notsurt True. But it is fine where it is. Permanently attached to the breadboard.
Any particular reason to have double V-groves? It would have been more space saving to have a single V-groove between boards.
3:57 - Clever!
Wouldn’t you want to solder the IC onto the board first? Might be worth mentioning
Thanks for the inspiration, i like it... I'm thinking about drawing something like this myself based on my own ideas or for special components. One question, how thick are the boards so that the connections fit well?
I'm using 0.1" male pin header for this. It's cheaper and more robust.

PCBWAY charges additional $100 extra for v-groves on my order. Did I do something wrong when ordering?
I seem to be running into the same problem. I'm curious to know if the 'IMSAI guy' paid that premium price or if maybe we are doing something wrong?
Try ordering through JLCPCB. I paid $19 for 5 boards. Same files but way different cost. And the V-grooves were included.
sweet!

01:19 "left, right, in the middle"
Tried to order the boards, order went under review and when approved the price went to from $42 to $143. Not paying that amount.
Those are more than 5 Designs per panel, JLC has specific wording for these cases and is upfront about it, when you look closely.
I uploaded the gerber files and submitted the order with JLCPCB and the price was a third of what PCBWAY wanted to charge me

yes, it is expensive I agree. all PCB houses can do Vgrooves

PCB castellations next please
do you think scoring V groves in both directions would work also?
It does work but most places only do V-cuts full board length, so there'd be less flexibility when it comes to sizes of sub-boards.
Have the board errors been corrected?
yes
Doing part 4/3?
I'll be using them for chips of the day

are the pins available from Our Friends in Thief River Falls?
Trying to find out where to get these pins in the UK.
Yes, cut-tape in-stock.
I hope your many junk boards end up in a freeby pile at the shop.
