I don’t need an Arduino or servos.
Thanks for gathering all the scattered info Randy. The 20 thumbwheels just
arrived, money to be collected by @jon together with the servos. I’m not
sure if you want money in advance for the arduinos, let me know.
Please add me to the arduino order. Thanks!
Thanks. This will be my first VHS project—I’m really looking forward to it.
@RandyNW: Please put me down for TWO arduinos. I would like to have a spare.
@interlock, Cool! @RandyNW pls allocate a pcb to @interlock, the servos are pre-paid due to the cost, date has been extended afaik. I have discrete parts for every pcb. You might need to order your own micro.
I made a google sheet that can be used to track who is getting what. I’ll fill in what I can derive from the discussion so far.

I’m not sure who paid for what already, so I think these members need to update the sheet:
@RandyNW @jon @TomKeddie @3bien

Thanks @interlock, updated your sheet from my tracking one.
I’m currently sitting at 15 17 ordered, one person ( @Jarrett) not wanting servos, and two ( @interlock and @sIGNgUY) who have said they want servos, but haven’t sent money yet. (or payment hasn’t arrived yet - can take a few hours…)
Thanks @jon. My payment is on the way.
A added a tab to the sheet with instructions for payment, it took a little searching to figure out how @jon wanted to be paid. Feel free to add any notes on how to accept payment for each parts stream in the document.
In retrospect, this may of made more sense as a wiki entry than a Google Doc. I just jumped at what I was familiar with.
Jon
I would like the required servos. Can you post the link and payment info
again. Thanks Paul
Servo group buy instructions:
Sent $35 via interac to Jon!
I’ve done a test build of my board. Seems ok so far, buttons work, I’ve not tested the thumbwheel pot or the stepper pins, will try to get to them soon. Need to buy a pot from @3bien.
The pin numbering for the micro on the piccolo schematic does not match the sparkfun micro pin numbering, a bit of a mind twist. Am hoping to build a test cable we can use to verify everyone’s board.
I forgot to mention I am out of 90 degree headers for the expansion connector (I have every other shape you can imagine). I ordered a bunch off aliexpress, will take a while but we don’t need them to build the piccolo (are about 20c each and optional).
Note that the 0.1" power connector I used is a hack and might not fit. I don’t like metric connectors so I don’t have a plug for the JST included in the parts list. I bought JST for everyone as per the list but you might want to solder wires onto the pads.
I also bagged up all the parts I have with the pcbs I have to make kits for everyone.

Hi Tom. The pcb looks good!
I’m going to order the Arduino’s tonight - there are no issues with the Pro Micro itself that affect what I should buy? Also, the first 5 I got came with a USB to mini-USB cable - do I need to ensure that the next batch have a cable, or is that expected and/or easy to find?
Nope the micro is solid, it is just that the piccolo schematic is hard to read because some odd decisions someone made.
Would be a good idea but most people have a few of these laying around. If we ever find them, there were some at VHS too,
I put in an order on AliExpress for 20 Pro Micros’s, in addition to 5 I already have. So there should be enough for everybody. I’m not going to update the spreadsheet yet from @interlock (great idea, thanks for that) until they arrive, because I don’t really know the final cost, but I’m not worried about getting paid right away. They will be around $8 each, definitely less than $10. I also order a few longer USB to usb-Mini cables, should we need them.
The last order took about 3 weeks so they likely won’t arrive until the end of the month.
The next step may take a while anyway. @funvill , you were up for organizing the laser cut and materials? I was looking at the build instructions, and they seem a bit hazy. We may want to try a couple of test runs, it sounds like the actual cutting plans may vary depending on exactly what materials are used. Although the specs are for 3mm, I think given the ranges they indicate, basically 1/8" is fine (with some caveats).
One reason I’d like to test run materials is that the different assemblies are just sliding against each other, so friction may be an issue (ie if using acrylic only). I’m also curious about using bamboo rather than mdf, I’m wondering if there are issues with that (laser, etc.)?
I know that a few people ( @TomKeddie , @Jarrett and probably others ) are going to take care of their own, but no douby there are several people (like me) who will need to be walked through this. In fact, the only reason I can identify which machine is the laser cutter is that I saw it touring the Bunker! I also have a feeling there may be a few iterations required to really optimize the Piccolo build so it would be nice to avoid too much wasted effort and materials.
Bad news on the servos - there were more than 100 available when I was running the numbers, however they’re down to 20 in stock, when we need 54.
Will they backorder? We’re some time away from laser cutting anyway.
Agreed, i will do a few test cuts before we order the acrylic for everyone else.
