[2019-01-27 13:52:39 CET] * Outsoft joined [2019-01-27 14:04:57 CET] * Outsoft quit (Leaving...) [2019-01-27 19:35:33 CET] * rune joined [2019-01-27 20:01:00 CET] * heinz joined [2019-01-27 20:01:15 CET] hello dave [2019-01-27 20:01:19 CET] Hello heinz [2019-01-27 20:01:25 CET] cold in ptsdam? [2019-01-27 20:02:06 CET] about zero. [2019-01-27 20:02:13 CET] no snow anymore. [2019-01-27 20:02:23 CET] and in england? [2019-01-27 20:02:30 CET] We are getting close, no snow yet. Usually 1st week february here [2019-01-27 20:02:52 CET] Snow in Scotland though. Where I live is about 5 degrees warmer [2019-01-27 20:03:06 CET] some news about zeddy? [2019-01-27 20:03:19 CET] News, yes. [2019-01-27 20:03:50 CET] I got my keyboard wired - removed and redid wires. Now its screwed onto acrylic backplate [2019-01-27 20:04:19 CET] congratulation. [2019-01-27 20:04:20 CET] And working well. Even got an extra shift key and 5 at bottom for arrows and "fire" [2019-01-27 20:04:44 CET] sounds interesting. [2019-01-27 20:05:03 CET] Also other news. I bought a couple of CBM C64s from one of Lizs friends. One pworked other had glue over keys and was dead. [2019-01-27 20:05:24 CET] Got new keys and fixed ROM. So now have 3 C64s working [2019-01-27 20:05:28 CET] Also... [2019-01-27 20:05:42 CET] I was in a charity shop and saw some coins. [2019-01-27 20:06:19 CET] what kind of coins? [2019-01-27 20:06:25 CET] one 1828 copper farthing, 1658 medal for death of oliver cromwell, Charles I 1635 shilling and a possible hammered coind from 1135 [2019-01-27 20:06:57 CET] did you buy some? [2019-01-27 20:06:59 CET] Not the best condition, but well worth what I paid [2019-01-27 20:07:08 CET] Yes all, for 8.00 [2019-01-27 20:07:16 CET] I couldnt walk past that [2019-01-27 20:07:36 CET] Also 2 old pennies minted 1912/18 at Heatons in Birmingham [2019-01-27 20:07:37 CET] really cheap. and 1135 is not a fake? [2019-01-27 20:08:15 CET] It could be a fake. But contemprary to 1135. Its on a mishaped bit of silver with the coin stamped at one side [2019-01-27 20:08:55 CET] Also the S is done my punching "dots" and not engraved. Probably an old die modified for some reason [2019-01-27 20:09:11 CET] send a picture of it, please. not now, but sometimes. [2019-01-27 20:09:18 CET] OK, wil do [2019-01-27 20:09:25 CET] Now, recommended movie [2019-01-27 20:09:38 CET] Green Card - true story and very very good [2019-01-27 20:09:39 CET] which one? [2019-01-27 20:09:52 CET] o.k. [2019-01-27 20:10:02 CET] will watch it. [2019-01-27 20:10:17 CET] Its just coming out. Watch what wins at the oscars [2019-01-27 20:10:31 CET] What about you - ZX News or nay news [2019-01-27 20:11:13 CET] green card from 1990? [2019-01-27 20:11:43 CET] No, 2019. [2019-01-27 20:12:07 CET] is it nominated for oscar grant? [2019-01-27 20:12:23 CET] Its about bigoted italian from new york hired to drive virtuoso pianist around deep south in America. [2019-01-27 20:12:43 CET] Yes, may orscar categories [2019-01-27 20:12:46 CET] many [2019-01-27 20:13:03 CET] Its a true story [2019-01-27 20:13:12 CET] do you know this from the trailer, or did you have watched it already? [2019-01-27 20:14:14 CET] I obtained it early... [2019-01-27 20:14:38 CET] If you want I send a copy on memory stick [2019-01-27 20:15:14 CET] thank you, but we will prefer to go into the cinema. [2019-01-27 20:15:38 CET] because of the athmosphere. [2019-01-27 20:15:50 CET] atmosphere [2019-01-27 20:15:53 CET] Yes, cinema is always better. [2019-01-27 20:16:07 CET] We went to see Mary Queen of Scots - I cant recommend it [2019-01-27 20:16:31 CET] Aquaman is good if you like superhero movies [2019-01-27 20:16:59 CET] Definitely go to see Green Card [2019-01-27 20:17:25 CET] you could not recommend maria stuart? [2019-01-27 20:17:51 CET] i intended to go in. [2019-01-27 20:18:01 CET] No, it seems they tried to please every minority [2019-01-27 20:18:13 CET] good to know. [2019-01-27 20:18:21 CET] it is cancelled. [2019-01-27 20:18:29 CET] Check the reviews on imdb.com [2019-01-27 20:18:40 CET] zeddy: [2019-01-27 20:18:44 CET] yes [2019-01-27 20:18:57 CET] i started to play a bit with step motors. [2019-01-27 20:19:10 CET] did you do this too? [2019-01-27 20:19:34 CET] No, only exposure to those are on my 3d printer. [2019-01-27 20:19:42 CET] I need to get an I/O card [2019-01-27 20:20:04 CET] Did you make a robot? [2019-01-27 20:20:14 CET] yes, i have a pio-card, running with zx81 and spectrum. [2019-01-27 20:20:39 CET] the idea is to drive a musical box. [2019-01-27 20:20:55 CET] Like MIDI? [2019-01-27 20:21:17 CET] i bought a step motor together with controls for 1.50 euro. [2019-01-27 20:21:49 CET] but the motor turns very slowly. [2019-01-27 20:22:09 CET] there is a gearing mechanism inside of the motor. [2019-01-27 20:22:24 CET] 1:50 [2019-01-27 20:22:50 CET] may be i will open the case and remove the gears. [2019-01-27 20:23:15 CET] i bought it on ebay. [2019-01-27 20:23:23 CET] I have an old scanner which will have stepper motors [2019-01-27 20:23:27 CET] keyword step motor. [2019-01-27 20:24:10 CET] i also have an old scanner. this could be an idea. to tke the motor from there. [2019-01-27 20:24:12 CET] 10 for 2.49... They are cheap [2019-01-27 20:25:00 CET] what about hard disks? do they have stepperr motors too? [2019-01-27 20:25:15 CET] I see 200 and 400 steps. Does that mean 200 or 400 steps per 360 degrees [2019-01-27 20:25:26 CET] No hard drives are controlled by magnets [2019-01-27 20:25:31 CET] i suppose. [2019-01-27 20:25:51 CET] i mean 200 steps. [2019-01-27 20:26:07 CET] I have about 50 hard drives in a box to throw out at work [2019-01-27 20:26:38 CET] I opened some for the magnets using tools and some more using abig hammer [2019-01-27 20:28:04 CET] do you have a pio-card? [2019-01-27 20:28:28 CET] No, I never thought I'd need one until tonight ;) [2019-01-27 20:29:19 CET] I would e good to go back to the mid 1980's when these were all available from Maplins [2019-01-27 20:29:28 CET] by the way, the soundcard can also be used as an io-card. [2019-01-27 20:29:48 CET] Does it need adapted? [2019-01-27 20:30:09 CET] the soundcard with ay-chip. [2019-01-27 20:30:24 CET] this chip has an io-port. [2019-01-27 20:30:34 CET] yes, do you take the I/O of the AY socket [2019-01-27 20:30:42 CET] i had used it for my speech chip. [2019-01-27 20:31:30 CET] do you have such sound card? [2019-01-27 20:31:56 CET] I have two PCB for the Harlequin with the AY chip on board. [2019-01-27 20:32:19 CET] Yes, I got the card from you or paul [2019-01-27 20:32:24 CET] good opportunity to play with steppers too. [2019-01-27 20:32:49 CET] Yes, I'll get the ZX81 back out when I finish with the C64 [2019-01-27 20:32:50 CET] joachim from the forum is a specialist for steppers. [2019-01-27 20:33:04 CET] It needs cleaned first [2019-01-27 20:33:20 CET] Oh, how is your hip? Will you get to Malherts [2019-01-27 20:33:28 CET] he is controlling his turning machine with it. [2019-01-27 20:34:00 CET] With a ZX81... turning a lathe or milling machine? [2019-01-27 20:34:02 CET] yes,i will go to mahlerts. [2019-01-27 20:34:19 CET] yes, with a zx81. [2019-01-27 20:34:32 CET] using code programs. [2019-01-27 20:35:02 CET] Brilliant! I am amazed at what the Zeddy can do [2019-01-27 20:35:13 CET] two years ago joachim has presented at mahlerts his egg painter. [2019-01-27 20:35:27 CET] I saw that. [2019-01-27 20:35:31 CET] did you see thevideo? [2019-01-27 20:35:40 CET] Yep, impressive [2019-01-27 20:35:56 CET] two steppers were used. [2019-01-27 20:36:27 CET] Do you connect the I/O directly to the stepper motor controller, or do you need some sort of buffer in between [2019-01-27 20:36:29 CET] one for turning the egg,#they second for guiding the pencil. [2019-01-27 20:37:05 CET] the buffer is on thee control panel of the stepper. [2019-01-27 20:38:09 CET] i have to increase the velocity. [2019-01-27 20:38:10 CET] So it is potentially easy enough for the likes of me to do [2019-01-27 20:38:27 CET] yes, really easy. [2019-01-27 20:38:49 CET] Change the gearing. Swap the gears so its 1:50 [2019-01-27 20:38:57 CET] i have driven it by forth (h4th), which is much faster then basic. [2019-01-27 20:39:29 CET] I found a great routine to simulate SINE and COSINE [2019-01-27 20:39:30 CET] i am afraid that the ripple will not long enough. [2019-01-27 20:39:46 CET] It draw circles using integer math a lot faster than FP [2019-01-27 20:39:50 CET] basic-routine? [2019-01-27 20:40:10 CET] Yes, but easily implemented in Forth. [2019-01-27 20:40:12 CET] i need this for forth. [2019-01-27 20:40:33 CET] please , send a file or an outprint. [2019-01-27 20:40:41 CET] I draw a circle using that and then overwrite using SIN/COS and there is very little difference on the Spectrum [2019-01-27 20:41:09 CET] i am very interested to get it. [2019-01-27 20:41:10 CET] I'll send the ZX Spectrum TAP. You can extract it from that? [2019-01-27 20:41:16 CET] Hold on [2019-01-27 20:42:35 CET] i have seen the coins. [2019-01-27 20:43:03 CET] If its real it is worth about 150 upwards [2019-01-27 20:43:48 CET] ??? [2019-01-27 20:44:39 CET] They are quite rare, and expensive. Some that are more worn that the coin star tat 150.00 [2019-01-27 20:45:20 CET] the coin looks very nice. [2019-01-27 20:45:22 CET] I cant see the SIN routing just now. Will send later this evening [2019-01-27 20:45:40 CET] o.k. let us stop for today. [2019-01-27 20:45:50 CET] Ok, talk next week? [2019-01-27 20:46:03 CET] yes, next week. [2019-01-27 20:46:08 CET] Bye for now [2019-01-27 20:46:10 CET] greetings to liz. [2019-01-27 20:46:15 CET] bye.
