[14:42:43] <Jymmm> http://www.electronickits.com/kit/complete/prog/ck1708.htm

[17:47:13] <IchGuckLive> O.O B)
[17:47:27] <c60> it's a steel?
[17:47:55] <archivist> it is a cassette size
[17:48:32] <c60> It's mostly a buckyball to me

[17:50:58] <c60> there's really supposed to be a subscript there,
[17:54:53] <IchGuckLive> what is bucky ? c60
[17:55:34] -!- adb [[email protected]] has joined #linuxcnc
[17:55:45] <c60> A buckyball, 4th state of carbon, 60 carbon atoms bonded in a sphere, named after buckminsterfuller, foundation of nano technology,
[17:56:07] <JT-Shop> Tom_itx: are you around?
[17:56:08] <c60> strength of diamonds but flexible, or carbon fiber but flexible on all dimensions
[17:56:41] <c60> and if you take a buckyball and put gold on some vertices it becomes a inverter or other basic computing bit.
[17:57:29] <c60> there's also some research utilizing it for delivery of radioactive imaging isotopes, basically they put the isotope inside a buckyball and it goes through your body, but unlike the isotope your body knows what a buckyball is and shits it out.
[17:57:56] <c60> nanotubes, basically elongated buckballs, with no top or bottom.

[18:03:07] <JT-Shop> to power a PIC in the field from a 24vdc power supply would a LM7805 with 1A output be ok?
[18:04:02] <archivist> should be
[18:04:05] <JT-Shop> and what does voltage dropout mean?
[18:04:13] <JT-Shop> http://www.digikey.com/scripts/dksearch/dksus.dll?FV=fff40027%2Cfff80182&k=7805+voltage+regulator&vendor=0&mnonly=0&newproducts=0&ptm=0&fid=0&quantity=0&PV69=80
[18:04:18] <cpresser> JT-Shop: depends :)
[18:04:32] <cpresser> LDOs have a minimum volate drop (eg input-output-voltage)
[18:04:45] <JT-Shop> I've seen some circuits that use a LM7812 then a LM7805 to get to 5vdc
[18:04:45] <archivist> the poor 7805 gets hot if dropping too much
[18:05:15] <JT-Shop> so better to go 7812 > 7805
[18:06:40] <archivist> I have never used two regs like that but it would share the power wastage
[18:08:04] <cpresser> how much power will you draw?
[18:08:07] <cpresser> just the controller?
[18:08:20] <JT-Shop> a PIC chip and a couple of optos?
[18:08:45] <cpresser> okay, that should be well below 50mA. Times 20Volts == 1Watt Heat generated in the 7805
[18:08:56] <cpresser> get a heatsink and you are okay
[18:09:03] <JT-Shop> ok, cool
[18:09:34] <pcw_home> a normal PIC (not DSPIC) will only be say 10 mA or so
[18:09:37] <archivist> is the 24v stabilised or a rough approximation
[18:09:47] <JT-Shop> are there input optos and output optos
[18:10:00] <JT-Shop> it is from a 24vdc power supply
[18:10:09] <pcw_home> so you need to add the max OPTO LED current
[18:10:18] <L84Supper> c60: any relation?

[18:11:12] <JT-Shop> this is the power supplies we use
http://www.carlogavazzisales.com/pspdfs/datasheetSPD60W.pdf
[18:11:45] <IchGuckLive> for power in a real board better to use mc34063A
[18:11:45] <pcw_home> for slow stuff you can get by on less than 1 mA for a PIC (more if you need xtal osc timing accuracy)
[18:12:12] -!- Tom_itx has quit [Ping timeout: 264 seconds]
[18:12:19] <JT-Shop> this is like one input per second max

[18:12:46] <pcw_home> How accurate is the timing required to be?
[18:12:48] <JT-Shop> just have to count to 100 or something like that and turn on an output
[18:13:31] <JT-Shop> I'm just counting each time the tilting bucket changes states in a rain gauge
[18:13:46] <JT-Shop> so real slow
[18:14:10] <pcw_home> OK so no xtal just a PIC and a couple OPTOS
[18:14:19] <JT-Shop> yes
[18:15:56] <JT-Shop> IchGuckLive: thanks for the tip on the MC34063AP
[18:15:58] <pcw_home> maybe a 8 pin PIC would have enough I/O
[18:16:38] <L84Supper> http://www.mouser.com/ProductDetail/RECOM-Power/ROF-78E50-05SMD-R/?qs=sGAEpiMZZMtwaiKVUtQsNWiU%2fn%252bYYHKMUYS0P1vLJVE%3d

[18:17:10] <L84Supper> $3.76 DC - DC switcher 5V out 500ma
[18:17:26] <JT-Shop> can't beat that
[18:17:55] <IchGuckLive> NP
[18:17:58] <L84Supper> then you don't have to worry about input or output caps or anything else
[18:18:10] <L84Supper> or heat sinks
[18:18:16] <pcw_home> But you only need 1 mA plus whatever the OPTOS need
[18:19:00] <L84Supper> it's only $3.76 for the whole thing
[18:19:12] <JT-Shop> I don't know where to start for optos
[18:19:48] <pcw_home> Does the I/O need to be isolated from the 24V?

[18:23:07] <L84Supper> a bit more $9.62 or use the non isolated supply + opto's
[18:23:23] <pcw_home> So maybe you dont need OPTOs or isolation, just dividers on inputs and MOSFETs on outputs
[18:23:48] <JT-Shop> well the input can be a 5v reed switch actually
[18:24:12] <pcw_home> the bucket switch?
[18:24:18] <JT-Shop> yes
[18:24:58] <JT-Shop> so really I just need to turn on and off the 24vdc input
[18:25:22] -!- holgi [[email protected]] has joined #linuxcnc
[18:26:31] <pcw_home> well just one darlington OPTO will do that so still less than 5mA total so a 7805 would be just fine
[18:27:06] <JT-Shop> ok, got a number for the OPTO?
[18:28:07] <L84Supper> can you use an opto-isolated relay? SSR?
http://www.mouser.com/ProductDetail/Clare/CPC1217/?qs=sGAEpiMZZMtJb2UpDWIubW29ERzDkclq
[18:28:15] <L84Supper> $1.39
[18:28:21] <pcw_home> SMD or through hole
[18:28:38] <JT-Shop> through hole
[18:28:44] <JT-Shop> so I can breadboard it
[18:28:57] <JT-Shop> I need to make a prototype

[18:30:29] <pcw_home> do you need more than one output?
[18:30:50] <JT-Shop> no, I just have to switch on and off one input
[18:34:33] <pcw_home> That should be fine
[18:34:57] <JT-Shop> thanks
[18:35:29] <pcw_home> A little higher voltage might be better (30 is not much more than 24)
[18:39:18] <tjb1> I hear from a teacher that Seco will probably be calling me :D

[23:40:37] <andypugh> These were in my garden making a noise today:
http://en.wikipedia.org/wiki/Coal_Tit they must be expecting spring. They are the only ones, it's freezing here and nobody can leav my folk's village for 10' snowdrifts.
[23:41:27] <JT-Shop> almost looks like our chickadees
[23:42:20] <JT-Shop> http://en.wikipedia.org/wiki/Black-capped_Chickadee
[23:43:01] <andypugh> They appear to be very close relatives.
[23:43:24] <JT-Shop> the bird in the photo
http://en.wikipedia.org/wiki/Tufted_Titmouse
[23:43:32] <JT-Shop> yes very related
[23:44:16] <JT-Shop> they have two songs one you can hear easy and one very high pitched one that is hard to hear
[23:44:43] <JT-Shop> I can only hear the high pitched one when they are up close and in my face
[23:46:43] <andypugh> I don't think I have ever been particularly close to a coal tit. I was about 6' away today, and was surprised at the odd noise it was making.

[23:49:32] * JT-Shop has to slip on the chef hat now
