Back
[09:28:10] <Kre10s> hey. is it just me, or are others alos having trouble logging in at atmel.com?
[15:34:24] <N1njaneer> Quiet day!
[15:35:07] <bss36504> Hey!
[15:35:23] <N1njaneer> Hey bss!
[15:35:29] <bss36504> long time no see
[15:35:49] <N1njaneer> Yeah, kept forgetting to log back in here on the rare reboot :)
[15:35:55] <N1njaneer> I missed you guys!
[15:35:55] <bss36504> yesterday is the first I’ve been on in months.
[15:37:02] <bss36504> It’s not the same without the banter. Im not on as much since I used to be on all day at work, and I dont work there anymore.
[16:04:08] <N1njaneer> bss36504: Aww, well, I've missed chatting with you for sure and am glad to see you back on again!
[16:04:32] <N1njaneer> bss36504: I guess I need to get the rest of my network stack working and ready for prime-time, new project that will actually be needing it soon. :D
[16:12:43] <bss36504> N1njaneer: ooh fancy, dont you just love it when a side project becomes helpful? Im working on building a custom head unit for my car to display vehicle diagnostics via the OBDII as well as operate as a normal stereo. It should be neat.
[16:16:12] <bss36504> Im using a 4.3” touchscreen display with an FT800 and some UC3 part (TBD). TI makes these nifty little dual channel 25W/channel class D amps that i plan on using for the audio section. Probably going to use an LT boost controller for the power supply.
[16:24:22] <N1njaneer> Sweet!
[16:24:25] <N1njaneer> Take pics!
[16:24:54] <N1njaneer> bss36504: Did you ever see the production helper pic? :D
[16:25:02] <bss36504> Oh I will. It will be a bit of a process, but hey, if I actually move forward with it, maybe I’ll do one of those blog things. And no I did not.
[16:25:20] <N1njaneer> https://www.dropbox.com/s/yq6ymvsw0o9nlzc/ProductionHelper.jpg
[16:25:24] <bss36504> Oh, N1njaneer, you might like to see my senior project: pmp.simpstek.com
[16:25:40] <bss36504> Ahahaha look at the little hooves!
[16:25:52] * bss36504 *squee*
[16:25:55] <N1njaneer> Yus!
[16:26:22] <N1njaneer> Also
https://www.dropbox.com/s/5exrn6l1bbsx7eo/goatswing.jpg -- different goat, couple months older
[16:26:42] <bss36504> do you raise goats in your spare time?
[16:27:34] <N1njaneer> bss: Ooh nice!
[16:27:47] <bss36504> yeah, I was quite happy it worked out.
[16:28:02] <Roklobsta> N1njaneer: The NSA thanks you for your informative pictures.
[16:28:06] <bss36504> haha
[16:28:33] <N1njaneer> bss36504: Yeah, as pets. Have three of them. They are great fun to take hiking. And two were bottle-raised so they had hung out at the office here with us for a few months.
[16:28:57] <bss36504> thats pretty badass. Goats are fun
[16:29:05] <bss36504> and that milled aluminum case
[16:29:08] <N1njaneer> Roklobsta: Yes, I will spam them with cute pictures until their resources are depleted.
[16:29:46] <N1njaneer> Yeah the aluminum is nice! We just brought in a brand new Haas mill so we can do similar kinds of enclosures for our stuff in the near future rather than having to outsource it.
[16:29:53] <bss36504> funny story, I sepnt like 10 hours on that, and then my computer engineer partner on the day of the presentation goes “wow, that case looks nice, but it took so long, why didnt you 3d print it?”
[16:30:01] <bss36504> I felt like an idiot for not thinking of that.
[16:30:13] <N1njaneer> The milled-billet clamshell kinds, so you can run them over with a car and not damage them.
[16:30:21] <bss36504> would have taken me literally 5 minutes to draft that case for printing.
[16:30:33] <bss36504> thats fun. Machining is a good time
[16:31:14] <N1njaneer> Yeah, just a lot to learn. At least I have the mill facing off the aluminum and have the probe system under control and haven't crashed horribly yet. I learned to switch the rapids to 5% REAL quick. :D
[16:31:35] <N1njaneer> And the best part is the new Haas's have a SAM9 at the heart of their panels :D
[16:31:44] <N1njaneer> Atmel for the win
[16:32:38] <bss36504> just be aware when you try and face off a thing piece of plate aluminum, that as you cut it, the vice will bend it. thats why the face is so lined; its only about .7mm thick in the middle. I was like “eh, fuck it, its still in one piece”
[16:32:44] <bss36504> thing=thin
[16:34:02] <N1njaneer> Gotta use a good quality machine vice with step-jaws or parallels, and then jig that thing in well! :)
[16:34:47] <N1njaneer> But yeah, gets tricky if it's thin and you don't have good grip/support on it.
[16:35:33] <N1njaneer> This mill is also a bit terrifying since the rapids are 1200IPM and it will do 15K RPM. Gotta run the thing slower until you're absolutely sure it's going to do what you expect. :D
[16:35:33] <bss36504> The shop teacher wasnt there to help me, er, scold me, so I overtightened it in the vice, then just felt like I was commited.
[16:35:45] <bss36504> 15K?! holy crap
[16:36:05] <N1njaneer> lol yeah I could see that :D
[16:36:06] <bss36504> thats sketchy. I dont trust the milling bits in my school’s shop enough for that even.
[16:37:06] <bss36504> In fairness, I did have the foresight to put in parallels and the back plate under the front plate in the vice, but they werent exactly the same size so it didnt support it how I wanted it to.
[16:37:13] <N1njaneer> I have some cheaper HSS end mills I'm using for learning on with the anticipation that I'm going to break a bunch. Will buy the better carbides once we have some better experience. But still nice that when the endmills are chucked in the collets and in the spindle we still get less than 1 mil of run-out on a tool that's 3-4 inches long, like a drill-bit.
[16:37:37] <Tom_itx> use proper feed charts and you got no worries
[16:37:56] <bss36504> Husky injection molding gave my school like 3K worth of carbite bits, but just about all of them are >1” so they tend to be overkill
[16:38:26] <N1njaneer> Accidentally set the collets in wrong the first time as I neglected to notice the pop-in arrangement and the collets weren't evenly compressing and I was wondering why the hell I was measuring like 8-10 mils of run-out. Oops :)
[16:38:37] <N1njaneer> bss36504: Oooh that's a nice donation!
[16:39:17] <bss36504> haha so easy to make minor mistakes whilst milling. I prefer lathe work honestly. It is quite a good donation! They also gave us some huge reamers
[16:39:55] <bss36504> Best feature of the MP3 Player: the volume goes up to 11.
[16:40:25] <N1njaneer> I've been having to buy things as I go. Got the mill without any tooling or holders, so having to fill all that in. Holy crap there's a lot of tools you suddenly want! At least spending the money for good quality American-made tool holders, though.
[16:40:38] <N1njaneer> bss36504: Right on! It'd better go up to 11!
[16:41:26] <bss36504> yeah, there are so many things you can spend money on in a shop. I would love to be in a position some day when Im rich and famous to afford a nice lathe and mill, but that is unlikely for the time being, so I just have to stay close to my school ;)
[16:41:38] <bss36504> when you get it to 11, the volume bar turns from green to red too
[16:41:39] <bss36504> haha
[16:47:05] <N1njaneer> The mill was a pretty reasonable investment, but I've had stuff come through where's we'd be paying a machine shop a quarter of the cost of the new mill to just run one job for us, and wait 4-5 weeks, when we could knock it out in an evening.
[16:49:48] <bss36504> absolutely, that makes sense. It makes less sense to buy one if you’re just going to tinker in your garage
[16:50:18] <N1njaneer> Yeah. Need it to do stuff faster! MUST GO FASTER!
[16:50:34] <bss36504> Should have gone CNC!
[16:50:39] <N1njaneer> That and I look forward to playing with it for knocking off quick 2-layer PCB protos doing the copper engraving.
[16:50:43] <N1njaneer> It is a CNC :)
[16:50:49] <bss36504> ohHH fancy
[16:51:00] <bss36504> I thought we were talking manual mill.
[16:51:02] <bss36504> my mistake.
[16:51:11] <N1njaneer> Nah. This is a brand new Haas :)
[16:51:28] <N1njaneer> Had to wait 10 weeks for the factory in Oxnard, CA to make it for us.
[16:51:41] <N1njaneer> Talk about one hell of a manufacturing operation out there. :)
[16:51:50] <bss36504> Oh yes, google informs me they are called “Haas Automation”. Seems self explanitory.
[16:52:09] <N1njaneer> They run over 300 of their own machines at their plant, making new machines. So they use their own products daily, which is smart.
[16:52:41] <N1njaneer> There is a cool and impressive (and actually well out of date) factory tour video up on YouTube that is still impressive as hell. And it's a few years old. They've expanded since.
[16:53:00] <bss36504> thats pretty cool. then if something breaks, or doesnt work right, the company is incentivized to produce a more quality product since production usually gets what it wants.
[16:53:33] <N1njaneer> Absolutely.
[16:54:40] <N1njaneer> That and the local Haas Factory Outlet is only about 6 miles from here, so we can get someone out here to service the thing 24 hours a day if we're down, and there's something around a million dollars in spare parts stocked at that location. Extremely fortunate, since that location covers the tristate area here. We could be 4-5 hours away, but instead we're a 20 minute drive :D
[16:55:29] <N1njaneer> They have an amazing operation, and ALL parts are made in the US, most at Haas's factory. Outstanding customer support. Main reason I went with them.
[16:55:41] <N1njaneer> If Atmel made CNC machines, they'd be Haas :D
[16:55:57] <N1njaneer> Save for the 24-hour tech support part, but that's what this place is for. :D
[16:56:00] <bss36504> Thats sounds like a good brand.
[16:56:03] <bss36504> I like good brands
[16:56:18] <bss36504> do right by me as a customer, and I’ll give you free promotion forever
[16:56:23] <bss36504> Thats why I like atmel.
[16:56:37] <N1njaneer> Pretty much the only US manufacturer of CNC machines. They also just shipped their 150,000th machine recently. Been in business since the early 80s
[16:57:34] <bss36504> 150K is not a lot of units, but then again, CNC machines probably arent exactly automobiles
[16:57:47] <N1njaneer> 150,000 CNCs is quite a lot of units :)
[16:58:12] <bss36504> Indeed, especially at many 10’s of thousands of dollars each
[16:58:27] <N1njaneer> These are huge beasts, too. Our mill is one of the smaller ones and shipping weight was 4,852lbs :)
[16:59:01] <N1njaneer> They have ones that easily exceed 20,000lbs
[16:59:48] <N1njaneer> The one we trained on at the HFO (A VF-9) has about the same interior volume as my Ford Escape, and has two stairs you need to walk up just to get to the door on the front!
[17:00:15] <N1njaneer> You could easily fit a mattress inside and take a nap
[17:00:28] <N1njaneer> Just don't press CYCLE START
[17:00:57] <N1njaneer> BZZZZzzzzzDEAD
[17:02:04] <N1njaneer> Anyhow!
[17:10:09] <bss36504> wow those are some serious units
[17:10:12] <bss36504> thats crazy big
[17:10:16] <bss36504> I gotta find you a video
[17:14:35] <bss36504> N1njaneer:
http://www.wimp.com/metalbutter/
[17:17:26] <N1njaneer> bss36504: Oooh yeah, that's like some of Haas's lathes. I have some nice brass shot-glasses they were amking at the local Demo Days last time
[17:17:43] <bss36504> Brass shot glasses! Sign me up!
[17:17:57] <bss36504> I should make some of those, but I dont have $40 I want to spend on brass stock
[17:18:17] <N1njaneer> https://www.youtube.com/watch?v=2n7PICO3vyo is a good example of something closer to ours, though this is on a TM-1. Ours is a fully-loaded SMM2
[17:25:22] <bss36504> it would take me like 4 days and 3 tries to make something like that manually.
[17:25:54] <bss36504> the rounded recesses alone have like 30 minutes worth of setup time just to get the radus centered in a rotary table.
[18:00:09] <N1njaneer> bss36504: Yeah, I like the idea of doing the parts in Solidworks and then just burping out the GCode to load in to the mill. Done!
[18:00:51] <bss36504> So nice :) We have a small, simple CNC at school, but nobody knows how to make it go. Maybe I should take that upon myself
[18:01:50] <N1njaneer> Do eeeet!
[18:02:03] <N1njaneer> Also look at HSMExpress - free CAM plug-in for Solidworks.
[18:02:22] <N1njaneer> They also have a commercial version if you need more than 2.5D milling, or 4/5th axis
[18:02:40] <bss36504> One of my teachers actually suggested that the department might be able to pay me as a consultant, so that is a good motivator for an unemployed college grad ;)
[18:02:53] <bss36504> I honestly dont even know the capabilities or specs of this mill.
[18:04:29] <N1njaneer> Sounds like some potential fun and profit!
[18:05:57] <bss36504> indeed. I’ll do it for free, but hey, Im not dumb enough to refuse money
[20:27:51] * N1njaneer attempts to tie bss down in the channel!
[21:55:14] <learath> https://www.kickstarter.com/projects/949348142/dc-one-power-supply-unit?ref=discovery looks interesting
[21:59:06] <Tom_itx> what tightarse hobbyist is gonna spend $70 on a power supply?
[21:59:36] <Tom_itx> all the ones i know cobble up a walwart or something
[22:00:00] <Valen> I got a free lab supply does that count?
[22:00:02] <learath> well I bought a 100$ one, but it's (in theory) 60v at 3 amps
[22:00:30] <Valen> (was dropped on the doorstep of a person who was picking some stuff up, add some duct tape and replace a pot or 3 and 1x tek lab supply
[22:00:45] <Tom_itx> i made one with surplus parts for my cnc 48v 18A for less than that
[22:00:46] <Valen> shorting it to set the current limit feels so damn wrong
[22:00:48] <learath> Nice
[22:04:01] <learath> 2.5-14v is a very small range for an "adjustable power supply"
[22:07:08] <Valen> didn't somebody else do one of those kinda recently?
[22:07:13] <Valen> all computer controlled
[22:34:31] <twnqx> i have the pieces around to build a 12V, 100A
[22:34:47] <twnqx> fed from my 55V, 12A industry PSUs
[22:35:15] <twnqx> i just am somewhat scared of those currents...
[22:35:34] <learath> 100amp? WTF?
[22:35:45] <learath> also, I don't think you can get 100 amps of 12v from 55v 12a
[22:35:53] <twnqx> i have 3 of those...
[22:36:06] <learath> oh.
