Chip with simple program for Toy

[Jyrki Halonen]

Transmutaatiotekniikasta.
*Maassamme ydinalalla on tuskin mitään niin tarkoin TABU:na pirettyä
systeemiä, kuin mahdollisuus neutraloida edes osin maailman vaarallisimpia
ihmiskunnan ydinjätemoskiaan ydinvoimalasaasteista. Päivän selvää on, että
tämä olisi mahdollista, koska sotilassektorilla systeemiä on pyöritetty
vuosikymmenet. Mutta siviilisektorilla ydinmoskiinsa hukkuva ydintehtailumme
ei suin surmin halua tutustua realiteetteihin, koska periaate "likaaja
maksakoon pahuutensa" panisi ydinteollisuuden vastaamaan ihan OIKEASTI
ydinrikoksistaan ihmiskuntaamme vastaan! Siksi ydinhallintomme ei edes
maksata TVO/Posiva,Fortumeiltamme rahaa asiallisempaan
ydinjätevarastointitekniikan kehittelyyn. Vaikka syytä enemmän kuin olisi!
Kyse on siis siitä, että täysin toimimaton "suolapintasuolammikkoviskonta on
olevinaan halvempaa!" ja todellisuudessa kaikki ydinjäte muutaman sentin
näennäissäästämiseksi pannaan suolavesiallikkoihinsa höyrystymään surutta
lastenlapsiemme tuhoamiseksi!

* Mitään edes alkeismoraalia ei tässä ydinröyhkeydessä voi sivistyskansa
nähdä toki. Yhtä kaikki asiasta on toki pidetty myös tutkimuksia. Mutta
koska transmutaatio ON realistinen maailmanlaajuinen mahdollisuus jo nyt
saati tulevaisuudessa, mutta pikkasen maksaa. Ennenkaikkea, koska
ydinhallinnostamme miljoonien hengenvaaraan asettaminen on..niin "hauskaa"?
Mitä ilmeisemmin vallankäytön, valtiydinterrorin työväline painetaan KAIKKI
myös tämän aiheen esittelykanavat hiljaiseksi. Siksi päätin, että nimenoman
minun tehtävänäni on ydinalanalan huippuosaajana maamme ensimmäisenä raottaa
tämän realiteetin muotoja vuosikymmenten 100% valtiotiedotuspimennostaan.
Tulevaisuuden ydirikoksen Nyyrbergin oikeudenkäynnissä nämä artikkelien
esilläolot tulevat toki lisäämään rajusti syyllistämisnäytöllään
vastuulliset ydinökymme ydinvaltiorikostemme tekijöiden paineita! Pidemmittä
puheitta valtion huippusalattua aiheeseen liittyvää materiaalia siis vihdoin
ja viimein myös TIETOISUUTEEN ja PALJON!:
--------------------------
Transmutaatiolaitteisto on eräs tärkeimmistä tulevaisuuden käytetyn
ydinpolttoaineen jälleenkäsittelyosasista! Laitteella saadaan tuntien
säteilyttämiskäsittelyllä pudotettua hengenvaarallisten käytettyjen
polttoainetankojen säteilytasoa 1000 osaan. Aiheesta löytyy loistava
artikkeli. Jokin aika sitten esim. Tieteen Kuvalehti käsitteli tätä pitkälle
kehitettyä innovaatiota ansiokkaasti.

Idean alkutaipaleet sijoittuvat Cernin hiukkaskiihdytinkokeiluissa
saatuihin tuloksiin. Tarkoitukseen tarvitaan järeä hiukkaskiihdytinyksikkö.
Perusajatuksena on hiukkaspommittaa, (ydinvoimapiireissä niin pidetty teema
tuo viimeinen), mutta asiaan. Testeissä on voitu havaita, että
kiihdyttimestä tulevat partikkelihiukkaset poistivat fissioprosesseissa
virittyneiden atomiytimien viritystiloja tramaattisesti. Ehkä yksi hyvä
vertaus tilanteelle olisi seuraava: Ydinreaktorissa oleva polttoaine on
"ikään kuin" kaupunki joka joutuu sotapommituksissa rauniotilaan. Tällöin
osittain sortunut talokanta sisältää runsaasti potentiaalista satunnaisesti
purkautuvaa "gravitaatioenergiaa" joka romahtaessaan ohikulkijoiden päälle
säteilee satunnaista gravitaatioenergiaansa vaarallisen paljon
ympäristöönsä. Nyt siis hiukkaskiihdyttimellä "murskataan" lisäpommittamalla
muodostuneet romahtamisvaaralliset rauniot. Tällöin siis rauniot jyrätään
"turvalliseksi ihmisille" alueella liikkumiseen.

No, miksi sitten ei voitaisi kuljettaa polttoainetankoja jo
olemassaoloevien hiukkaskiihdyttimien luo saamaan käsittelyä? Kimurantiksi
tilanteen tekee, kun muistetaan Euroopan laajuinen massiivinen vastustus
tämän käytetyn uraanin edustamaa supermyrkyn kuljettamisesta
surullisenkuuluisaan eurooppalaiseen hyötöreaktoriin. Tämän opettamana se
vaihtoehto onkin koettu riskialttiiksi. Ehkei näillä turvattomilla aineilla
kannata vaarantaa kokonaisten valtioiden olemassaoloa. Muuten, kuin
ydinvoimaloita tehtailemalla tietenkin.

Jos jo aineen kuljetus koetaan ongelmalliseksi, on nostettu esille ajatus
että halvempi vaihtoehto olisi kehittää liikuteltava laitteisto. On
laskettu, että jopa yksi eurooppalainen yksikkö voisi käsitellä koko
maanosassa muodostuneen ydinpolttoainekertymän. Näin laitehankinta tulisi
maakohtaisesti täysin realistiselle tasolle, jotenka hintakaan ei ole
ydinvoimapiireille ylittämätön. Jonkinverran ongelmia on tuottanut tämän
pienehkön laitteen tehon saaminen riittäväksi. Mutta suuremmissa kiinteissä
hiukkaskiihdyttimissä on jo nyt saatu riittäviä tehoja. Tämä ei ole ongelman
ydin.

Miksi sitten suomalaisessa ydinvoimakeskustelussa järjestelmällisesti tämä
toimiva tulevaisuuden tekniikka halutaan jääräpäisesti torjua? Miksi TVO/
Posiva konsortio, piittaamatta kiistattomista laitteen tuomista eduista,
haluaakin pikaisesti haudata jätteensä tulevan laitteiston
saavuttamattomiin. Toisihan ydinjätelakiin aiheesta lisätty
transmutaatiokäsittely kiistatta lisähintaa konsortion ennestäänkin kalliin
omakustanteisen ydinsähkön hinnan päälle. Julkisuuteen tulisi ihmisille
selvemmin esille, että kuinka vaarallista ja epävakaata peliä yhtiö pelaa
torjuessaan tämänkin loistavan idean.

Sitten vielä, TVO/Posiva konsortion tarkoituksena oli jo
loppusijoitusluolaston paikkaa kartoittaessaan seuraava. Aikoinaan geologit
ilmoittivat Olkiluodon kallioperän niin huonoksi luolaston sijoituspaikaksi,
ettei sitä rankattu edes 100 parhaimman suomalaisen loppusijoituspaikan
joukkoon. Koskapa se sijaitsee oseaanisen laattatektoniikan
törmäyspisteessä. Jossa Atlantin selänne luo kasvavaa puristusta yhä. Koska
tämä valtamerellinen sedimenttimurskevyöhyke luo loppusijoituspaikalle
kenties suomen huonoimmat ja epävakaimmat säilytysolosuhteet.

Miksi sitten TVO/Posiva konsortion kovassa painostuksessa Olkiluoto otettiin
väkisin 101 vaihtoehtona mukaan? Koska alueella oleva luonnonmerisatama luo
loistavat mahdollisuudet tuoda maailmalta huomaamatta ainokaiseen
ydinjätevarastoon vaivatta kovalla valuutalla käytettyä ydinmateriaalia.
(Asiaa muuten TVO on varkain , tarkoin piilossa julkisuudesta aktiivisesti
kysellyt jo 5 vuoden ajan mm. Ruotsin kautta maailmalta Suomeen
kuljetettavista ydinjätteistä mm. Olkiluodon satamaa hyödyntäen! Sain
ennakkotietooni vahvistuksen "sisäpiireistä" mm. 2008!) Tämän
transmutaatiolaitteen mukanaan tuoman helpotuksen takia saattaisikin tämän
loistavan ydinmonopolibisneksen perusteet murtua. Koska vähemmin säteilevää
polttoainetta voisi jokin "kilpaileva" taho myös varastoida muualle ja vielä
Posivalaista vaihtoehtoa turvallisemminkin. Silloinhan selviäisi myös, että
kuinka kehnosti Posivalainen loppusijoitusluolahahmotelma on suunniteltu,
verrattuna "oikeampaan" vaihtoehtoon. Silloin loppusijoitusbisneksen
hintataso luonnollisesti laskisi ja TVO/Posiva konsortio ei saisi kaikkia
haikailemiaan rahoja.

disfunctional like Rod approaching on the same side, you'ld move to
the other side of the street at least 100 yards before he could get

[Mika Sandberg]

Alan arvostuksesta kertoo varsin suoraan se miten alan ammattityöväestö
suhtautuu tekemiseensä. Siitä voidaan ottaa esimerkkejä laajasti.
Ammattilaiset haluavat usein myös jälkikasvustaan työnsä jatkajia.
Yritysmaailma on pullollaan työstä ylpeitä isältä pojalle siirrettyä
sukuosaamista. Mutta yksi ala loistaa poissaolollaan. Yksikään ydinalan
ammattilainen ei kehu firmaansa julkisesti netissä, lehdissä, ei edes asiaa
kyselevälle lapselleen. Jos katsomme ketkä julkisuudessa ydinlobbailevat,
niin yhtään alan ammattilaista ei taatusti näy lehtiotsikoissa, netissä
saati mualla. Vain rahalla ostettavia politikkoja ja vastaavia, jotka eivät
erota uraania hiilimustasta taatusti.

Rupesin todella ihmettelemään miksi. Ja ennenkaikkea KETKÄ ovat maassamme
nykyään ydinalan ammattilaisia? Heitä on maassamme tietysti tuhansittain,
mutta keitä? Heille on yhteinen piirre se, ettei näillä ole esim.
perustuslakiemme mukaista lakko-oikeutta, kellään! Toinen keskeinen piirre
on niinikää lainvastaiset ylipitkät jopa 12h työvuorot ja loputtomat
ylityöjaksot vailla omaa päätäntäoikeutta. Kolmas ominaisuus on tekemänsä
työn arkaluontoisuus, mikä tarkoittaa orjallista vaitiololupauspakotetta
uhkailu-ukaaseineen ydinjohdolta. Esim. OL-1,OL-2 ja OL-3 työmailla ei
KETÄÄN saa mennä vapaasti jututtamaan tekemisistään ja määräys on ehdoton,
vaikka maamme pitäisi olla demokratia. Mikä kertoo myös alan valonarkuudesta
ja hämäryydestä enemmän kuin paljon.

Niinikää ydintyöläisten palkkataso on enmemmän kuin romahtanut loistonsa
päivistä. Jos lasketaan Suomen ydintyöläisten ansiotasot saadaan tyytyä jopa
7 euron tuntipalkkoihin! Reippaasti alle jopa siivoojaminimistä puhutaan
ydinalan ammattilaisistamme keskimäärin kautta maamme! Kun vielä 70-luvulla
ydinosaaja oli huippupalkkalainen ja arvostettu, on hän tänään lähinnä
kansan hyljeksimä reppupuolalainen, liettualaisorja, turkkilainen, yms.
joita katsotaan pitkin nenänvartta, jopa kaupan kassalla, koska heitä
arvotetaan toki myös olemattoman orjapalkkaostovopimansa mukaan
olemattomuuksiin. Ja tieto siitä, että suurin osa ei maksa edes veroja,
saati sotuja ja vastaavia alentaa tasoa mutasarjaan kansan silmin.

Vaarallisesta työstä johtuvat moninkymmenkertaiset sairastumisriskit
työtapaturmista, kielitaidottomuutensa takia tulee valtavasti
onnettomuuslisäriskejä, samoin kouluttautumattomuuksistaan, säteilystä ja
vastaavista lisäriskeistä kiistatta puhutaan ydintyöläisissä. Hyvällä ei
näihin pitkälti "slummiparakeissaan "huuhaileviin" ydinorjin suhtauduta enää
edes harmistuneitten kauppiaitten piirissä. Säteilyvaaransa takia heillä on
normaalityöläisiä ankarammat
lääkärintarkastusvaateet jne. Ydintyöläiselle on kauhistus , jos lapsensa
tulisivat samaan työhön jatkajiksi.Voi vaan hämmästellä kuinka nopeasti
ydinalan mega-arvostus on romahtanut nykyiseen mitäänsanomattomuuteensa.
heijastellen sitä pettymystä mitä ydinvoiman loisteliaitten lupausten
romahdettua tshernobyliin on tuottanut. Voi vaan arvailla, että kuinkan näin
totaalisen pettymyksen ala saa enää jatkossa KETÄÄN kiinostumaan sen
ylläpidosta?

The RFID chip is for determining the owner of the bin.

Which would only work if the binmen always returned the bin to the same
house. Mine do seem to manage to do that though. How about a comunity scheme
where everybody swaps bins a few houses to the right every week?

Ours are always returned to the correct owner. Most people paint their house number on it! I don't bother as a bin is a bin and we don't have a weighing system.

My neighbour gets annoyed if I put them the wrong way round though (our driveways are next to each other so we wheel each others up and down), as he keeps his clean and I don't!

Hi,

I want to encode a mono audio signal into a digital squarewave where
the repitition frequency is the same as the instantaneous incoming
audio,

This could be FM, if you mean that the repetition frequency is
proportional to the instantaneous value of the audio signal...

and the pulse width is proportional to the amplitude.

This could be PWM...

So, you want _simultaneous_ FM and PWM? Why?

Good question. The resultant FM & PWM pulse train will be used to gate
a high frequency pulse train, probably in the order of 400kHz. I want
a recognisable form of the original audio, very much NOT hi-fi but
recognisable none-the-less, to be recoverable from the final, gated,
high-frequency pulse train.

It seems your question needs some further clarification.

My bad - I should have been more explicit - part of the issue is that
I wasn't too sure of the final requirement myself.

many thanks for all your comments so far - very helpful.

Assuming now that I'm after FM & PWM, and I'm not worried too much
about nyquist or hi-fidelity, can anyone recommend a simple approach
using say a PWM controller like the TL494 or whatever?

Cheers

If you are interested in a single frequency, then just develop a
little serial protocol to send the data over and over again. I'd
suggest async characters, but you can do whatever you want.

If you are interested in encoding a band, like the audio band from 0
to 3kHz, then you can use FM to encode both the frequencies and the
amplitudes of the input. You basically need a voltage to frequency
converter, and on the other side, a frequency to voltage converter.
This is how radio works.

However, one simple scheme is to digitize the input, and send the 8
bit data on the 400kHz line using some serial protocol. For audio at
3kHz or less, you can sample at 6kHz, generating 60k bits of data per
second (using a 10bit A2D). So, for async, you'll need a link rate
faster than 75kbps.

One advantage of doing the serial scheme is that you can test it with
a PC, and generate data with a PC as well using a simple program...

*Nykyään täysin epäonnistunut Ranskalais/Belgialainern ydintoivon
vääjäämättömänä kohtalona on olla katto palasina erään EU:n
ydinosaamattomuuden kaikkein kallein vuosimiljoonien ydinjätteen
muistomerkki täynnä hallitsematonta ydinkauhun tekniikkaa. Mukanaan tämä
ydinalalle tyypillinen megaepäonnistuminen vei toivon mm. ehtymättömän
ydinpolttoaineen illuusioista. Taloudellisia ja terveydellisiä määriä ei
edes uskalleta julkisuuteen laskea.

Ranskan jälleenkäsittelykuningas La Haguen uhkapeli:
Tarkoituksena akujaan käsitellä miltei yksinäänRanskan omien vanhojen
grafiittikaasureaktorien käytettyjä polttoaineita. Joiden radioaktiivisuus
on vain viidennes verrattuna kevytvesaireaktorin jätteen säteilyyn!! HAO
jälleenkäsitteli viimeksi mainittua vain 2-kuukautta 1976. 1977 lopulla
laajennettiin, mutta todettiin heti riittämättömäksi ydintyyliin. Läheinen
Cherbourgin kaupungin valtuusto on ilmoittanut kaikin keinoin vastustavansa
laajentamisia!

*Länsisaksalaisen ydinkriitikon Robert Jungin mukaan La Haguen ympäristö on
sekä maalla, että merellä radioaktiivisesti saastunut. Hän kertoo, että
kriittisten tiedemiesten ryhmä on todennut läheisellä maa-alueella 10-20
kertaa virallisesti sallittuja säteilyarvoja suurempia arvoja. Ranskan
virannomaiset ovat jyrkästi kiistäneet tällaiset faktat, joita myös La
Haugessa käyneet ruotsalaiset lehtimiehet ovat tuoneet julki.

*Toki Saksassa ja Ruotsissa tiedettiin ranskalaisen ydinfarssin olevan
joutsenlaulusaan jo silloin. Nykyään Euroopan kaikki uraani lähetetään
kiltisti jo vuosikausia vähin äänin ja noloina Venäjän Majakin, joka sekin
laitos lopetetaan tänä vuona 2008 Putinin mukaan. Maailmassa ei Englannin

ei ole sen enempää energiapositiivista uraanikiloa enää ikinä
käytettäĺvänään. Ei kierrätysuraania, eikä siis enää edes
kierrätysplutoniumiakaan mistään! Mutta kuten alan ideologia on aina ollut
kaikki totuus kielletään vaikka sydän märkänisi.- Ja toden totta kaltaiseni
ydinalan yyberosaajat on niitä aniharvoja jotka faktoja kasvavasti

Will ship to USA address only.

send me an e-mail (((( richklestinez(at)charter.net ))))))) change the
(at) to @
I will send you the pictures of them testing a 6L6 tube.

Most of them I have seen on e-bay and this one
http://www.vacuumtubes.com/B&K_707.html seem to be in the $300 to $400
range if they are working and in good shape.

I have a TV-7/U also that I will be selling as soon as I get rid of all the
tubes that I have. It is my pride an joy and is pretty darn good shape
although I havent calibrated it in about 3 years. Also I have a dual trace
B&K model 1479B 30Mhz oscilloscope which works great. some other stuff too.

Let me know

Hello,

On the first page under Typical Applications theres a schematic
titled: adjustable output regulator... and I can't figure it out,
there's an equation there for Vout, but to me it looks like Vout would
be 12V because it's from the output pin to ground... there's a voltage
divider with a pot, but I don't see how the pot does anythign since
Vout is taken from Vout pin with respect to ground... Woooo but the
ground pin of the voltage regulator is in the middle of the votlage
divider.... so there is 12V across R1.... I'm confused.

Basically I want to use this voltage regulator as an adjustable
voltage out... I was originally just planning to put in a voltage

would my way be ok?

*NO*

*YES*

much thanks!

You looked up the data sheet so are probably smart enough to learn basic
electronics without too much difficulty.  You need a much better grasp
of circuit theory and instruction on asking intelligent questions before
you can expect the professional users of groups other than
sci.electronics.basics to be friendly.

You can start learning by answering the questions (in the group
sci.electronics.basics *ONLY*):

What is your load and what is its minimum and maximum current requirements?

What is your supply voltage and what is it from?

N.B LM340-12 is absolutely the *wrong* choice unless you only want to
adjust from 12V to lets say 15V.

That's my good deed for the day done,  Merry Christmas all.

Did I cross post wrong? I thought it's ok to add commas and put in
more than one group name when you post.

You should *ONLY* post to groups where your question is ON TOPIC and
relevant. If you aren't sure if its an appropriate group, you may ask
*briefly* if it is. E.g. Subject "LM340-12: Can I a beginner's
question?", Body "I need an adjustable voltage output of around 10V. I
have read the LM340-12 data sheet. I need help with designing a circuit.
Can I ask here or is there a better group?" would have got you *polite*
directions to sci.electronics.basics or maybe even the comment "Well
this isn't really the right group but have you looked at ......... site
where there is a circuit that will help you?". Before posting to a
group *always* read about a week's worth of recent messages to get a
feel for the group. This reading without posting is called 'lurking'
and is a *GOOD* thing.

Some of the regulars on S.E.D (common abbreviation to first letters
*within* a group) have designed chips that sold millions. As an
ordinary tech with many years in the repair trade who's been into
electronics all my life, I know enough to follow their arguments and can
understand their circuits if I study them hard, but there is an elegance
in the designs they knock out in an hour that I couldn't duplicate
without years of work. There are also some, mostly of lesser
accomplishment who delight in misleading newcomers.

I don't read alt.engineering.electrical, but there is precious little
connection between most of electrical engineering and low power
electronics. If you want to design a custom mains transformer, try there.

S.E.misc is low traffic, for stuff that really doesn't fit elsewhere.

This group is the 'tutorial' group.

*MANY* users killfile (automatically throw away unread) *all* messages
to more than 3 different groups. These are usually the users that have
been using the groups the longest and have the most experience. They
are exactly the users you should want to interest in your question.

Due to inappropriate posts and spam from Google Groups users, there in
an increasing move towards killfiling all of you on the technical
groups. There is not a lot you can do about that except to get proper
newsreader software (which works like an email program that runs on
*YOUR* computer, not on a webpage inside your browser window) and sign
up with a News (or NNTP) Server. Some of us still read posts coming
from Google. Few of us use Google to post from.

As I *dont* use google, and I quoted the whole of your message, You
*MAY* get some answers from those who don't normally see posts from Google.

Thats enough education about USENET, I'll try to give technical help in
the other fork of your thread.

The ground pin isn't connected to ground, so it'll no longer have 0V on
it, it'll have on it whatever the voltage is at the junction of R1 and
R2.

The regulator will use that voltage as a reference and will output a
voltage 12V higher than that.

My supply voltage is around 24V, and I want a 10V output... so I was

regulator and using a pot to dial in 10V out... the load will have a
draw of around 300mA.

---
The problem with that is that if your load current varies then the
output voltage of the divider will too.

Plus, you'll be wasting power in the divider that you don't have to.

If you have a constant current load, all you have to do is put a
resistor in series between it and the output of the regulator: View in
Courier:
12V
/
+24V>----[LM340-12]---+
| |
| [RS]
| |
| +--10V
| |
| [LOAD]
| |
GND>---------+--------+

If your load drops 10V with 300mA through it, then the series resistor
needs to be:

Vs - Vl 12V - 10V
RS = --------- = ----------- = 666 ohms
Il 0.3A

and the power it'll dissipate will be:


PD = (Vs - Vl) Il = (12V - 10V) * 0.3A = 0.6 watts


680 ohms is a standard value and if you can live with the smaller
voltage into the load, a 1 watt resistor would work OK.

620 ohms is also a standard voltage ind it would work if your load could
stand a little more than 10V into it.

That's not really a good way to do it, though; an LM317 would be much
better.

Could you elaborate a little more on please on what they are trying to
do on that datasheet, and on what would be wrong with my approach?

PS - I thought a 12V regulator outputs 12V... but you said you can use
it to adjust between 12-15V... is this true?

---
Yes.

What you do is use a voltage divider to raise the ground leg of the
regulator above ground and the output will regulate at its normal output
_plus_ that voltage.

A LM317 might be a better choice but at 0.3A you'll be dissipating at least
3.6W and more as you adjust for lower voltage (higher volt drop in the
regulator), so look into how big a heat sink you'll need.

You can reduce the dissipation by finding a lower voltage source.
