Title: Northwest Washington state. (Between Seattle & Canada)
Post by: jimLee on Dec 13, 2016, 05:54 am
Is there anyone out there? I've a nice office/shop in Anacortes that would work great for meetings.

Any local newbies like some hands on tutoring?

Let me know!

Oh man, I'm in Bothell.  It would be awesome to hook up and collaborate but would have to be on the weekend.  Long drive but it would be worth it.

I actually run into a few problems on my current project and soon be posting on here to ask for any help and ides.  I'm not a total noob, but am far from EE.

Mostly I get an idea and then put it together from bits and pieces from around the web.

This is great! Bothell's not too far away. The more people we gather up, the broader our pool of talent gets.

Lets see what you're working on.

I'm a competitive shooter and I reload my own ammunition.  One day an idea struck me to have an Arduino based system installed on the reloading press.  The system keeps an eye on primers being low, gunpowder being low, that there is a powder in the case before bullet is added on (very important as no powder bullet will have enough force from the primer alone to be driven into the barrel but not enough to go completely through and the next shot fires into it and at best you just blow up your gun, at worst, well you get the picture).  Also I didn't like that I had to load cases and bullets by hand so I designed and and wired to the controler two automatic collators for them.  It automatically orients them in the right way and drops them down to the press and stops once there is enough of them. The whole system has audio and visual indicators.  Code is all done too.

I got a messy prototype working with a lot of 3d printed parts.  Now I need to streamline the design, so I will use Atmel 328 chip instead the whole arduino.  For now I work with dip28 package but ultimately will move to quad pack smd to shrink down the design.  The design bellow includes power regulation as I need 12v for two 5rpm motors and want to drive all of it with a single wall pack.  My amp estimates puts me with everything running at around 500 milliamps.

I'm also trying to figure out which software to use to design pcb so I can have them done professionally as several of my friends express that they want this system for their presses.  I don't want to use Eagle as its too complex.  I'm trying KiCad, Fritzing, and EasyEDA.  I've been using ExpressPCB software but it locks me in with that manufacturer and they are somewhat expensive.

Anyway, take a look at the schematic and see what you think.  I'll try to post some pics and maybe vid of the prototype in action.

Wow! What fun! My brothers used to reload all their ammo. It was "the thing" going on in the garage back in the late '70s.

As for PCB design, I'm more a s-ware guy and shaky with hardware. But, when I do hardware, I always use ExpressPCB. I think they are just the cat's meow for that. Now that I think of it, I've been using them off and on for over 15 years! Wow!

Your machine is built up of 3D parts. You have a 3D printer? I've a couple and they are some of the most fun ever!

Very cool designs.  I want to take on a quadcopter myself but I have to finish reloader project first.  I can segway into another project easily so I'm trying to keep myself on track.  Speaking of trucks, that's an awesome army truck in the pic with the cup holder design!

ExpressPCB wants around $200 for 10 boards.  Same from PCBCart or FirstPCB is around $80, and additional boards after initial order are $1-2 each!  I emailed both companies to see if they can work with ExpressPCB files.

I got two 3d printers.  My original is Prusa I2.  I build it from instructions and mix of parts from web and ebay.  Not easiest experience to say the least, but I learned a lot.  My second one I just purchased a little while ago as a kit from web.  It a delta design and mainly I got it because i think it is most mechanically graceful printer in existence, it's like a mechanical ballet. Pics bellow.

I'm ok with code.  But I definitely write code that's probably overly long, simplistic, and messy, but ultimately it works.  If you look at my code you'll probably have a good laugh.

I find that people either do Code or EE. Each can kinda' do the other but the thinking is too different. I'm definitly in the code camp.

Funny about that cup holder. I run that truck all the time 'cause its fun to drive. But, like I discovered when grabbing a burger, where can you put the drink? That cup holder was so amazingly handy!  So I posted it on the forum where people restore those trucks. All I got was "I'd never drink and drive." Ah, no imagination those boys!

I've 2 Makerbots and we ran the heck out of them. Quads are easy, draw an X put the motors at the ends and the controller in the middle. The rest is just style.

I see all your reloading parts, how do you keep all the bits, casings, primers, slugs oriented? What happens when one is flipped over? Can the machine tell?

Here are some pics of the reloader parts I made.  First is the gunpowder hopper with printed addition to hold more.  Atop sits a switch that if you are low on powder the plunger will press.
(https://forum.arduino.cc/index.php?action=dlattach;topic=441705.0;attach=191403)

This is a low primer sensor.  It's made from one led and photoresistor.  Primer interrupt the led light.  Arduino reads analog input from photores and acts accordingly. No primers, light on, input reading high, etc.
(https://forum.arduino.cc/index.php?action=dlattach;topic=441705.0;attach=191405)

The next pics are of the squib (no powder in the case) detection system.  First pic is of a sensor that gets tripped when case goes up and the powder level causes the little ram to hit the switch if it's correctly filled.  The second pic is of a second sensor that tells arduino that it's time to check for squib, which is at the top of the reload stroke,  otherwise the arduino would constantly scream the there is a squib.

Here are the pics for feeding systems for bullets and cases.  Here's the collator of bullets, it picks them up, flips them if facing pointy end down, and sends them down the feeder tube.  
(https://forum.arduino.cc/index.php?action=dlattach;topic=441705.0;attach=191411)

Here's the sensor attachment.  It sits above the feeding die and when the bullets stack up to this level, hits interrupt sensor and motor stops.  I wanted smooth and steady motors so I picked up 12v, 5rpm motors off of Ebay.  Bonus of a 5rpm motor is that due to the gearing reduction is has loads of torque so I can put a lot of bullets and it goes like a champ.
(https://forum.arduino.cc/index.php?action=dlattach;topic=441705.0;attach=191413)

Same principal applies to case feeder.  Although a little easier to get the cases oriented the right way, as they don't stay in the pockets since the base of theirs is so much heavier.

Here's the "brain box" where the Arduino sits, all the wires go into, and the lcd resides.  As this is a prototype inside is an Arduino with a mass of wires going to the veraboard hosting electronic components and connections.  I don't like this setup long term, hence I want to go the single chip, all on the one board solution.  Couple of screenshots of different messages, with custom icons I designed.

Post by: MPawlina on Dec 18, 2016, 11:38 pm
Lastly, if you look carefully, there is a small wire sticking out on top the box.  It is attached to one of the digital input on the Arduino and when you touch it you get all the sensor readings on the screen.  I thought it would be nice to have some troubleshooting build into it as ambient light may play havoc with the photoresistors and some thresholds may need to be adjusted.  Another lesson I learned, don't use semi-transparent PLA for photosensors (insert palm smack on the forehead here).

My attempts (aka hack jobs, lol) on improving my circuit board design.  Version one sits inside the prototype, but here's my attempt (V2) on making an Arduino shield, worked but still a huge mess.

Ha! PC boards what a wiring madhouse. I had/have two EE brothers. One of them liked doing high power stuff. The last project I remember was the power & control section for an electric jumbo jet tug. Man, you do not want to get that wrong!

Look at the number of downloads your pictures are getting. Now either you can't get enough of them and are clicking like mad or we have a lot of people reading this topic. I wonder if any are local to us?

Welcome!

I've been in "bitland" all weekend. Sounds like both of you guys are down by Seattle. W9SPY, you're the latest arrival, lets hear what you have planned. And if you need help, I'd be happy to have a shot at helping you. I come from the code side of things so I'm shaky in the electronics department.

I'd love to have a maker weekend but it seems unfair to drag both of you all the way up here.

I've been working on running different screens on my Arduino. Then I switched to a Teensy for more memory. The Teensy is tiny but programs the same as the UNO. And instead of 2k RAM it has 64K. The code space is way bigger as well. And, instead of a 16mgz clock mine's running at 72Mhz.

Hi I live in Federal Way and would like to get involved. Anacortes is about a 2 hour drive from me. My wife passed away in Oct. and I lost all interest in doing anything. Maybe getting around some people with like interest is what I need. If you ever have a get together please let me know. I am  retired and can come up any time.

Maybe have a meeting with the ones that are interested. This topic is not read that much. Need to get more coverage, like adding meeting time and dates  to our tag line or there maybe more ways. But I think we need to meet with the others to see what they want.

How about a Saturday or Sunday in March for starters?

Jim it was a pleasure meeting you. Looking forward to getting together in the future. I need to get myself turn around to day time hours. I think the reason I got so befuddle was that I sleep till about 12 noon. So Saturday i got up at 9 am so I could drive to your place and be there by 12 noon. To many years of working grave shift.

 You have a need place to hang out at. Just wish you were closer. My problem is fighting Seattle traffic. Once north of Seattle it's not bad.

Oh by the way I got my laptop back from the doctors office, they had to replace the hard drive then tried to recover the data off the old drive. The got most of it.

Well I saw that your definitely a tinker, and you know you code, the only problem is you choice of computers. Well not everyone is perfect. What a boring world it would be if we were all perfect.

Thanks for the program I was going to ask if you still had it. I will order some more neopixels. I will fill in the rest of my project with those and see how they work.

Once again it was fun and i'll try to set up another day for a meet.


By the way where is your web site?

Yo!  It's Aaron, the 'next island over' guy. :)

Yeah, lemme check on the Saturday thing, but my guess is that'll work.  (With kids, there's always the question of:  "What will I have to trade the wife for a few hours off?" :)))

Assuming I can escape, I'll bring along my current breadboarded project, which is an Arduino Mega 2560-based player for old arcade video game music, based on a couple of Yamaha single-chip synth ICs. It's not much to look at, but it's mildly amusing to listen to.  Most of the work has been on the PC side, devising ways to rip the music from the games and compress it into something that can fit into the Arduino's flash.  I know I could just go to SD, but as a former data compression engineer, I'm enjoying the challenge of fitting as much into the MCU as possible.  Right now I've got almost 9 minutes of music (not counting looping) stuffed into the 2560's flash, but I'm not giving up until I've doubled that! :)

Hope to see you guys soon!

Indeed, that looks pretty awesome, Jim.  It's really great to be able to catch up in person and see what others are doing with this stuff.  Those enclosures really "finish" a project, too.  By comparison, most of my projects are naked rats-nests!  I need to figure out how to get past that stage.

And on that note:  I shared your buddy's injection tooling site with my coworker, who was thrilled at the prospect of finding some local help for his project.  He's expressed interest in stopping by the next get-together.  He's an electronics enthusiast but not an Arduino guy--yet.  But moreover, he's a 3D printing and laser enthusiast.

JA, if we can get your buddy & Mitch here, that would be fantastic! We may want to have more than one meeting / month. Or, we can do random meetings, depending on what we're all into at the time.


As for the light : What happens is the light draws power from the pull-up resistor to ground to do its blinky thing. On my teensy it pulls the pull-up low enough to trigger the doorbell. I'm not really happy about letting one of the Teensy's neurons out there on a wire into the wide world, but I can only do so much at a time. I'm hoping that for this one it'll be fine.

Ran into a really strange issue yesterday and last night. Every hour so two it would go off. SOmetimes it would shut itself down too. Weird! Like a ghost was testing it. I've rewritten my button debounce/filter code and hope this'll solve the issue? (Fingers crossed)

Ha!  Well...  Sort of.  That is, if "madly acquiring parts" counts as "some progress." :)

I've decided that my next adventure is going to be replicating--and then enhancing--the functionality of my breadboarded rat's nest on actual Capcom arcade hardware.  I believe I mentioned that I'd found some games that used the synth as well as the PCM chip (which I don't have) for music?  Well, as I've continued to rip music, I've found more and more of those--probably half of the Capcom CPS1 library!  Poo!!  I wasn't prepared for that at all.  The PCM chip on those boards is an odd beast, with its own private bus and a wacky 4-bit data format.

So, I had this funny idea a while back:  What about just taking the actual arcade motherboard, piggybacking the Z80 audio CPU with the Arduino, and bus-mastering the Z80 bus to take over control of all the audio hardware.  I've spent about a week's worth of nights studying the hardware, and I believe I have a workable plan.  And it'll be cool!  Best of all, I think I can do it with only a few minimal modifications to the motherboard and without removing any components--which seemed like the only polite thing to do, as these boards are sort of collectible anymore.

So I ordered a Street Fighter II board off eBay (it's a CPS1 title) and should have it next week.  It's remotely possible that I might have something working with it by the next time we catch up, but at the very least I'll bring the disassembled boardset along and can describe my ridiculous plan of attack. :)

OK I'm thinking we try to standardize on 1st Sat / month. That means this Sat Afternoon. If this works out and we want it to happen, we can make it 1st & 3rd. But for now, we'll shoot for first.

I have a few that may want to join up.

We'll see..

You guys?

Alas!  I leave for Arizona on Saturday.  It's the kids' Spring Break, and we decided (for once) to actually do something. :)

But, generally speaking, I think "first Saturday" is as good an idea as any.

Sorry I just saw the date change. I'll try to make the next one. I marked this thread to let me know when there is a new post. Do you want me to update the post for Active user groups to show that we are meeting on the first Saturday of the month?
Title: Re: Northwest Washington state. (Between Seattle & Canada)
Post by: jimLee on Apr 05, 2017, 08:38 pm
Yeah, that would be a good idea. I'm going to make it 1st & 3rd and see how it goes. That'll give people some schedule flexibility and be able to skip meeetings that don't fit.

I better mark this thread to notify me as well..

I'll do my best to make the 15th.  It may be another shorter-than-I'd-like-it-to-be visit, or else I may have my boy in tow. :)  My coworker Justin may tag along also.  If Mitch was going to make it, perhaps I can convince Justin to drag along his desktop injection molder for show-and-tell.  It looks a bit like a bullet reloading press.  Justin's been slowly accumulating the necessary gear to injection-mold a small product he's selling.  He's so far been 3D printing it using a couple of small "UP"-style 3D printers, and the yields have been poor. (The other possible solution for him, should the injection molding turn out to be a dead end, is to upgrade his 3D printing setup to something MakerBot-esque.)

Ingredients for v2 of the game music player are mostly accounted for now.  Chances are very slim that I'll have anything new actually working for 4/15, but 5/6 would be a certainty.  In any case, I'll bring what I have, working or not!

Well, Mitch is planning on making it. I'm planning on firing up the BBQ. I'm thinking burgers and/or dogs. Guy, (Shell Oil) is planning on coming. I sent messages to Tim/Tom. Tim's thinking about it, Tom's not responded. Kurtis (Airframe Mech.) I'm working on as well as Steve (Boat design, tooling & Banjo builder) We should have enough talent in there to build a Starship! Should be a fun time. Oh and Nate (Ex mechanic, now builds race cars)
 
Oh, my blasted Coke machine stopped cooling its cans. I gotta' figure out how to fix that. Pipes are all frozen but the heat exchangers aren't exchanging heat. Odd that..

BBQ sounds excellent.  Please give me some kind of shopping list--chips, dip, drinks, hamburger/hotdog supplies, etc.  I *will* bring something, so make sure it's something you want! :)

I took care of two weekend's worth of around-the-house projects this weekend, so I'm looking forward to a guilt-free visit on Saturday, heh.

I picked up a Papilio Duo--basically, an Arduino Leonardo married to a Xilinx Spartan 6 FPGA and a 2Mb SRAM.  Nifty!  So I'll bring that along for show-and-tell too.  For a variety of eeEEEEeevil reasons (to be discussed on Sat), it's going to replace the Arduino Mega 2560 in v2.  Or, well... I *think* it is.  I've so far only worked with Xilinx's newer Vivado toolset, and the Spartan series chips require the older ISE toolset.  I'm playing with ISE now for the first time, and I can see why they replaced it!

Ok lets see.. Not sure how to delegate this..

I'll do the basics..
Burgers :
Buns
Meat
Mayo
Ketchup
Mustard
Relish
Cheeze
Onions
Dogs:
Buns
Other:
Soft drinks
Ice (Coke machine broke)
Beer?
OK now you can get a better idea of what's missing. Chips, desert, salad, chili, soup->nuts.. What would you like to see here?

That certainly seems like a great spread, Jim.  How about I pick up an assortment of deli salads, chips/dip, and some cookies or brownies?  Happy to do requests, though!

You are more N welcome! Thanks for coming!

 I think I'm going to make a list of prospective projects people want to work on. Also, it looks like people would like to take field trips to each others workplaces. I think we'll try to hit Mitch's Machine shop next time for a show & tell. If possible I'd like for us to tour your place to find out about building pressure sensors.

Steve was saying he could demonstrate some of the techniques he uses for building the banjos.

I'm bummed I didn't pressure Justen (?) into demoing his plastic injection machine. I would have really liked to have seen it work.

And now I have two c++ students. I hope I can teach. (Fingers crossed!)

Fun fun fun!

Yes, a tour of workplaces would be awesome!  Justin and I might have to work on the boss a bit.  He's a super guy, and very amenable to drop-ins during the week, but he tries hard to protect his weekends--as I would have to do, if I had a home/office/lab setup like he does.  In lieu of a tour opportunity that appeals to our meetup schedule, Justin and/or I could certainly bring in samples of our work and do a presentation/slideshow kind of deal.

Glad to hear about the C++ students.  Hopefully they've got projects in mind that demand C++ skills, too.  Motivated students are the best kind!

I'm sure we can get Justin to bring back his injection molder, especially if he's able to get a mold made for his part!  I tried to eavesdrop on his conversation with Mitch, but couldn't quite manage it.  I'm hopeful they had a productive meeting-of-the-minds.  He'll fill me in tomorrow, I'm sure.

As for other possible agendas:  When I finally get my Glowforge (early July?  Fingers crossed!!!), I'll have to bring that in for a Laser Day and let everybody burn stuff. :)

I'm planning on having the shop open this Sat afternoon if anyone would like to show up.

I'll also be there Wed. evening as well. 'Cause I'll be teaching my first c++ Arduino class. (Complete beginners)

Hi, I know NOTHING of this circuit board stuff...I am a 51 year old female that wants to learn to use these things for running sound, lighting, etc for a haunt. I want to start with wearables then move up. I live in Mount Vernon, so we are neighbors. Oh, and January is a good time for me. I am working the Lights of Christmas so my time is really limited this month. Thanks for being here!

Hello brecky. Jaholmes is from Guemes Island just across the channel from Anacortes. Naneen is from down south. Below Seattle? Not heard from either for some time.

For wearables have you looked at the Adafruit stuff? They are totally into the wearable thing there.
