[05:20:09] <z64555> oh! forgot I had a book that covers oscillators
[05:20:13] * z64555 dives in
[07:29:02] <Snert> I need a schematic of an oscillator circuit to use for a clock.
[07:29:42] <Snert> doesn't have to be accurate.
[07:29:53] <Snert> doesn't have to be really, very stable.
[07:30:14] <Snert> it just has to sit there and clock a decoder.
[07:30:26] <Snert> nothing else is referenced to it.
[07:30:59] <z64555> It's an old book, but its theory checks out
[07:31:20] <z64555> It's got two RLC tanks around a transistor
[07:31:32] <z64555> lemme pull up a name
[07:32:02] <Snert> Wouldn't I have to square up that sine wave before I could use it?
[07:32:40] <z64555> no idea.
[07:32:47] <z64555> tune plate, tuned grid oscillator
[07:33:06] <z64555> there's also a hartley and a colpitts oscillator listed
[07:33:09] <Snert> o...well, no valves here :)
[07:33:31] <Snert> I been looking at hartley and colpitts.
[07:34:00] <veverak> e/budzoe
[07:34:02] <veverak> aaaa
[07:34:04] <veverak> :)
[07:38:51] <z64555> I *think* the triode tube can be replaced by a FET
[07:39:21] <z64555> I also remember the esistance of something called a ceramic resonator
[07:39:27] <z64555> *existance
[07:40:34] <Snert> thx. I'm googling and refreshing my memory. been awhile.
[07:43:07] <z64555> yw :)
[07:44:16] <robopal> w2aew has made tutorial videos on oscillators, hasn't he?
[07:45:45] <Snert> perhaps. But all I need is a schematic of a working circuit.
[07:45:56] <Snert> I don't need the 101 theory.
[07:46:34] <Snert> I know how they work and what they do.
[07:54:40] <z64555> then you should be able to make a schematic :P
[08:02:38] <z64555> huh. you can even use an op amp as a hartley or colpitts oscillator
[08:03:09] <z64555> now that I think of it, that would be a logical "duh"
[08:32:06] <Snert> yea. I'm looking for a source of canned circuits. The ground is well trodden.
[08:33:02] <Snert> just havent happened on a good website or book yet.
[14:22:47] <flyback> love this track

[15:44:14] <anniepoo_> bad thing about robotics is superglue under the fingernails
[15:44:39] <anniepoo_> and having to stop mid cool project to go buy 4-40 hardware
[15:46:54] <deshipu> anniepoo_: I found that using gelled instant glue makes it much easier to avoid glueing your finger
[15:47:13] <anniepoo_> yup, definitely
[15:47:17] <doomlord> whats the state of servo tech
[15:47:28] <doomlord> are they on an improving trajectory or stuck
[15:48:03] <anniepoo_> I'm terrified of the stuff. I once nearly lost my vision to it. Was using the modelers brand with the separate applicator tips. Was in the habit of blowing the holdup out after I finished.
[15:48:03] <doomlord> ( r.e: the strength and agility of robots vs biology)
[15:48:13] <anniepoo_> biology's winning
[15:48:20] <deshipu> doomlord: hobby servos are stuck at "sucks", smart servos are stuck at "fucking expensive", there are some custom-made servos for robots that are really great improvements
[15:48:31] <myself> I've had one too many close calls with adhesives, I'm really strict about safety glasses now.
[15:48:49] <deshipu> I always work in glasses
[15:48:53] <deshipu> not safety, though
[15:48:54] <myself> and 4/40 hardware gets really cheap in 1000-count, I can't say enough good things about it :)
[15:49:01] <anniepoo_> yes - after doing this 999 times, time 1000 a tiny drop flew into my eye
[15:49:13] <deshipu> even though I don't actually need them, they already have some scratches from flying parts
[15:49:18] <myself> Same about soldering, molten metal to the cornea will really wake ya up
[15:49:24] <anniepoo_> I had a spot in my vision for 3 months, and was terrified I'd go blind
[15:50:02] <anniepoo_> now I'm religious about safety glasses for one thing, and that's using alpha-C glues
[15:51:03] <myself> yeah, I may or may not for soldering, depends on what I'm doing, but glues and grinders, 100%.
[15:55:20] <z64555> ah, it'll buff right out
[16:05:01] <anonnumberanon> doomlord, good servos are too expensive for reasonable projects
[16:05:36] <doomlord> are robots destined to be cripples forever
[16:06:02] <anonnumberanon> Tom_itx, hey, how to tell in the store which toaster has 2 or 4 elements, it's the pipes that are under the baking tray and above it? Should be 4 pipes?
[16:06:22] <anonnumberanon> Triffid_Hunter,
[16:06:25] <anonnumberanon> jhylands,
[16:08:21] <z64555> doomlord: nah, just their components
[16:08:37] <z64555> supply/demand, and all that
[16:09:53] <doomlord> do you think as processing advances, once people see interesting robot capabilites, demand would push servo advancement?
[16:10:12] <doomlord> or are there material/physics limitations.
[16:13:21] <anonnumberanon> doomlord, I'm work9ing on it right now, trying to make very strong, torquy and cheap servos
[16:13:34] <anniepoo_> 8cD nice!
[16:13:42] <anonnumberanon> good ones are $30, trying to bring it down to 10 or 15
[16:13:46] <anniepoo_> anon, how are you doing the manufacturing?
[16:13:49] <doomlord> anonnumberanon interesting, can you elaborate?
[16:13:55] <doomlord> i am interested to hear what the issues are
[16:13:56] <anonnumberanon> no
[16:14:12] <doomlord> trade secrets?
[16:14:27] <anonnumberanon> yes, but if you really want to it's easy to research yourself
[16:14:36] <anniepoo_> anon, I'm partners in an engineering facility. We might be able to handle production when you get that far.
[16:15:06] <anonnumberanon> anniepoo_, okay good to know thanks, I'm drawing and prototyping right now.
[16:15:25] <anniepoo_> http://www.theelginworks.com/
[16:15:34] <anniepoo_> 8cD thats us
[16:16:25] <deshipu> got my ears to work!
https://www.youtube.com/watch?v=hDExwmWhYX8
[16:16:27] <z64555> what an odd smilie
[16:17:06] <anonnumberanon> anniepoo_, check out my robot on Youtube, valflyinf
[16:17:09] <anonnumberanon> is the channel
[16:17:19] <anonnumberanon> called "inside the shop of a robot maker"
[16:17:24] <anniepoo_> 8cD
[16:17:45] <anonnumberanon> i need good servos for THAT robot, the ones I have at present are strong but not tough, (break early)
[16:18:56] <anniepoo_> are you using hobby servos, or robotic servos?
[16:19:43] <anonnumberanon> hobby
[16:19:51] <anonnumberanon> gotta go buy a reflow oven ill be back
[16:20:04] <anniepoo_> hey
[16:20:09] <anniepoo_> hmm...
[16:20:11] <anonnumberanon> (also testing if hobby servos are okay for robots, so far so good with the brackets I have)
[16:20:23] <anonnumberanon> robotics servos are expensive as fuck
[16:20:34] <anonnumberanon> >> so unusable fore reasonable and serious projects
[16:20:55] <anniepoo_> we ended up with a spare powder coating oven. wonder if that'd work for you
[16:21:14] <anniepoo_> we've never even had it outta the box.
[16:21:32] <anonnumberanon> no its an emergency for me to have it
[16:21:36] <anniepoo_> ok
[16:21:38] <anonnumberanon> gotta go bus is in 10 min;utes
[16:21:43] <anniepoo_> toaster oven
[16:21:44] <anniepoo_> see ya
[16:21:59] <anonnumberanon> (will let me bake a coolant part on a car that i just painted) will get my car back on the road
[16:22:49] <anniepoo_> gotta admire a man who doesn't have a working car, but considers a reflow oven 'an emergency'
[16:22:54] <anniepoo_> oh, LOL
[16:23:44] <anniepoo_> and yes, robots are hard
[18:42:25] <flyback> flyback> anyone know of a way to make a soic-8 test clip with stuff at home
[19:05:51] <anonnumberanon> anniepoo_, the car is working, it had a huge coolant leak, came from a pipe that had a pinhole due to rust, already filled it with JB weld, finish curing in an hour, then i will paint the entire pipe with a strong paint and cook that, when it's cooked it will be good as new, ill put it back on the car and then I'll never have coolant problems again.
[19:06:09] <anonnumberanon> Because I may soon work an hour away, it will be good to have a reliable car.
[19:06:24] <anonnumberanon> I've already swapped the brake pads and calipers.
[19:15:44] <jhylands> anonnumberanon, when you go to buy a toaster oven for doing reflow, just make sure you don't get an IR model
[19:17:09] <anonnumberanon> Okay i got home i have it here let's check it jhylands
[19:19:02] <anonnumberanon> It is this one:
http://www.amazon.com/Oster-TSSTTV0000-Versatile-Countertop-Toaster/dp/B004RAUATK
[19:19:24] <anonnumberanon> IR, as in infrared?
[19:19:32] <jhylands> yes
[19:19:57] <jhylands> that one looks reasonable
[19:20:12] <anonnumberanon> i now discover the amazon reviews are not good
[19:20:15] <anonnumberanon> damn it
[19:20:18] <jhylands> well, you'
[19:20:23] <jhylands> you're not cooking with it
[19:20:27] <anonnumberanon> "after a year it stopped working properly"
[19:20:35] <anonnumberanon> yesh I'm not lol
[19:20:50] <jhylands> to use it, you'll set the oven temp on max
[19:21:02] <anonnumberanon> and switch it on/oof
[19:21:05] <jhylands> and adjust the temp of the oven buy switching power
[19:21:24] <anonnumberanon> I'll have to go back to your parts page for the project, i liked it iirc.
[19:21:29] <anonnumberanon> There are thousands online.
[19:21:47] <jhylands> http://blog.huv.com/2007_03_01_archive.html
[19:21:53] <anonnumberanon> So tonight I'm only cooking a automobile coolant hose in it so i can cure the paint im putting on it.
[19:21:59] <anonnumberanon> It's engine block enamel.
[19:22:09] <anonnumberanon> Strong stuff, but better if cured with heat.
[19:23:01] <anonnumberanon> jhylands, thanks
[19:41:41] <akem> hi, what's new at #robotics
[19:49:27] <z64555> letsee... some guys working on servos, a line follower bot with PID controller
[19:49:41] <z64555> anonn's cooking a coolant pipe
[19:50:18] <z64555> and something about "canned oscillators"
[19:50:54] <akem> hm i see no giant killing machines.
[19:51:26] <akem> 'canned' sounds ok anyway
[19:54:09] <Jak_o_Shadows> I'm starting work on the gaming tabletop
[19:54:11] <anonnumberanon> Better cook my coolant pipe than my engine. Although I did drive for a minute or two with the ultra hot light in the dashboard.
[19:54:22] <Jak_o_Shadows> which isn't exactly a robot, but it has stuff in it
[19:56:04] <z64555> anonnumberanon: air cooled. lol
[19:56:42] <anonnumberanon> VW Beetle works that way. The first one they made.
[19:57:06] <anonnumberanon> I have a big fan in front of the engine, it was blowing hard so that's good at least.
[19:57:08] <z64555> yeah, but it was designed as such
[19:58:12] <anonnumberanon> I'm trusting this page to replicate the results:
http://forum.saiga-12.com/index.php?/topic/64977-baking-engine-enamel-really-speeds-up-cure-time/
[19:59:06] <anonnumberanon> JB cured in 30 minutes, gonna just setup the oven and apply 1 light coat, wait 10 min, another light, wait 10 min, then a heavy one and immediately put in oven for 1h at 250 fahrenheits
[20:02:16] <anonnumberanon> Actually ill let it sit for the night after paint and cook it tomorrow morning.
[20:02:20] <anonnumberanon> (the meth)
[20:36:44] <anonnumberanon> Jak_o_Shadows, so tell us, what does it hab?
[20:53:13] <Jak_o_Shadows> well, I've barely started the physical construction
[20:53:23] <Jak_o_Shadows> But will have a network of micro-controllers that control lighting effects and such
[20:53:34] <Jak_o_Shadows> connected via i2c probably
[21:25:21] <anonnumberanon> cool
[23:39:17] <anonnumberanon> pipe is drying...
[23:40:25] <flyback> too bad im not
[23:43:47] <anonnumberanon> Your pipe is not drying?
[23:44:32] <flyback> thought you said dying
[23:44:32] <flyback> nm
