I am finally in Thailand, after a grueling 15hrs of air travel. I got to South Africa on 5th September and of course hit the mall to look for grapes. Unfortunately they are not in season at the moment, but they will be when I return in October. On Saturday 6th I left for Thailand thru Hong Kong. After the contortionism I did on the plane to fit in the seat of the plane, I now know why economy class is called Economy. Skimping on space, and quite possibly, food!!! Tall people like me need to be taken into consideration, maybe make and upright bed to use all that space above our heads. When I landed in Thailand, the heat of the place is what hit me first. I thought that I could handle heat because I am an African, but was I wrong!!! This place is like a steam bath, only that you are steaming yourself in public. But it is great, and I am looking forward to moving around in the coming days. BTW, Thank God for Kenyans, because I happened to meet one on the plane and he visits here often. So he helped me change my money and get a taxi at a reasonable cost, saving me from probable extortion (seeing that it is obvious I am not from these parts). The roads here are very good (point to take home) and we drove and drove till I got to the hotel. As my friends had already told me, their grasp of English is miniscule at best, and so I was freaked out that I would be taken to a different part of the city. But I was able to communicate with the driver, and I can finally sleep, in a bed that considers my dimensions. So far, the only thing I have not gotten, is some sunshine. I am african, and I expect the sum to be out. However, It is cloudy, and I am irritated. I just want to see proper sunshine, not sunlight!!! Gatwiri |

I remember back in highschool, I had friends who liked to experiment. Especially when it came to weight. A few went down the path of becoming anorexic and bulemic, just to satisfy the opinions of others. When I heard they were doing this, I would shake my head in disapointment, that wasn't a good path for them. It was a dangerous path. So, I would talk to them about it. I remember what I used to tell them also. I would tell them that if they continued to deny their bodies food, their stomachs would begin to shrink until finally, due to lack of food, it would begin to eat itself. I would be extremely graphic about this, in hope they would end this fad. That's all it was, a fad. Well, at least until it became more serious, then it would be considered a disorder. If that little rant of mine woudn't work, I would explain to them that if they didn't have a certain number of calorie intake a day, their body would start using the stored energy in their muscle to keep their body going. That means that they would have less muscle mass and more BFP (body fat percentage). In that way, it made no sense to continue their little excapade of eating disorders, for it would not help them, but harm them. Now, I stopped them before it became too serious. If you've got a friend with an eating disorder, talk to them, ya, but I suggest you get some real help. I believe that crash dieting (the beginning of what could lead to serious eating disorders) is a fad. Just like obesity. If you look around America, what do you see? Think of McDonalds. Super-Size Me. We are considered to be the most obese country in the world. The top ten obese cities are: Memphis, Tennessee: 34% obese. Birmingham, Alabama: 31.3% obese. San Antonio Texas: 31.3% Riverside/San Bernardino, California: 30.8% obese. Detroit, Michigan: 30.4% obese. Jacksonville, Florida: 29.8% obese. Nashville, Tennessee: 28.8% obese. Oklahoma City, Oklahoma: 27.5% obese. Kansas City, Missouri: 26.9% obese. San Diego, California: 26.7% obese LINK: http://www.associatedcontent.com/article/631953/forbes_list_most_obese_cities_in_america.html?page=2 It's outrageous. We haven't always been this obese. Think back to the 20's. I believe obesity is a fad, a new life style. Now, I'll admit some people honestly can' help it, due to some sort of medical issues, but the ones who can, the ones who just decline any offer of exercise, or refuse to stop eating those nasty greasy burgers and whatnot, I find it sad. If you just had the determination, you could do it, because once you get started, it's hard to stop. Working out becomes your addiction, let it become your drug. And trust me, it's much healthier than smoking or drinking alcohol, or taking LSD. Take on the challenge and lower those obesity rates. If 1 out of every 4 obese people did it, I bet the numbers would decline pretty fast. Obesity isn't healthy. TTAC. |

On 30 June 2007 a new exhibition celebrating the life of Diana, Princess of Wales will open at her former home, Kensington Palace. Marking Diana's life as princess, mother, fashion icon and humanitarian, the exhibition features over two hundred photographs, alongside memorable film footage of one of the world's most famous and admired women. The exhibition will run until the beginning of January 2008. Diana: a Princess remembered is an audiovisual exhibition drawing on memorable moments in the life of the Princess. Beginning with the shy teenage girl who captured hearts around the world and then as a blushing bride, the exhibition follows her growth into a sophisticated princess and dedicated mother, who became internationally respected and admired as much for her beauty as for her tireless work for charities. Hundreds of photographs have been brought together with television footage, to create the largest collection of images of Princess Diana on public display in this anniversary year. The exhibition looks back over Diana's life and achievements focusing on four memorable aspects of her life as: princess, mother, fashion icon and humanitarian. These themes are also explored through interviews with people who knew the Princess of Wales personally. Designers Elizabeth Emanuel, Bruce Oldfield and David Sassoon talk about working with the Princess to create the stunning evening dresses and formal day wear for which she was renowned. Photographers Jayne Fincher, Tim Graham, Arthur Edwards and Ian Jones talk through their memories and stories about photographing one of the world's most iconic women, during her public duties but also at more private moments. Finally, representatives from some of the many charities she patronised and supported recall the Princess's work with them, and how she often used her celebrity to bring difficult issues to the fore, raising awareness and deepening understanding of important causes. The tour finishes with a set of stunning portraits of the Princess of Wales by Mario Testino and an interview with the photographer in which he tells the story of probably her most famous photo shoot. A selection of Diana's dresses, that raised a staggering $5.7 million for charitable causes when auctioned, are also displayed. Diana: a Princess remembered will be open daily from Saturday 30 June 2007 until the end of the year. Entry to the exhibition is included in the admission Kensington Palace ticket holders.

Loogiku prototüübi võib lugeda valdavas osas valminuks. Hetkel on lugemi võtmise sagedus umbes 250 hertsi, mis on küll elektrisignaalide uurimiseks häbiväärselt vähe, kuid sellega saab nii mõndagi teha. Saatsin laualambi abil fototransistorist moodustatud pingejaguriga vastvõtjale signaale ning koostasin sellest Excelis graafiku. Fototransistori takistus sõltub temale langeva valguse intensiivsusest, selle abil on võimalik ehitada pingejagur, mille väljundpinge on sõltuvuses valgustusest. Pinget tõlgendab kontroller mis muudab selle vahemikus 0-3.6v(toitepinge) väärtuseks 0-255. ![]() Pingejagur ![]() S-O-S morsesignaal Edasiseks võiks skeemi plaadile joota ning muuta püsivaks. Samuti tuleks tõenäoliselt välja töötada parem tarkavarile lahendus arvutile. Kuid praegu on plaanis hakata arendama veebikaamera abil nägevat sihtijat. loogik3.zip |
|
Loogiku edasi arendamine on täies jõus ning põhiliselt on asi praegu koodi taga. Oleks tarvis teha wxPythoni abil mingit sorti graafiku joonestamise liides, kuid siiamaani pole ma ennast sundinud wxWidgetsi graafilist poolt õppima. Eelmises blogipostituses kirjeldatud probleemi - korraga rohkem kui 8 baidi info liigutamist arvuti ning seadme abil USB-d kasutades - jaoks olen leidnud lahenduse, mis on esialgu lihtsam, kuid võib-olla vähemtäiuslikum. Olles uurinud minu loogikPC-programmi koodi, võite olla märganud, et on kasutatud funktsiooni controlMsg. Järgnevalt räägiksin veidi antud funktsiooni tööpõhimõttest: USBtiny abil rakendatud USB-seade ootab ebastandartseid pakette ning reageerib nendele. Üks usb-pakett (setup-tüüpi, see, millele seade vastab) koosneb kaheksast baidist. USB setup-pakett Bait koosneb kaheksast bitist, ning seda võib kujutleda kui 0000 0000 Vastavalt kahendsüsteemile võib iga 0 olla ka 1. Ühe baidi maksimumväärtus on 255 ning miinimumväärtus 0, selles võib veenduda kahendsüsteemi kasutades. Meid huvitavad setup-paketi 2. bait ning 5. bait. 2. baidis peitub seadmele saadetud käsk - mida peab tegema. Erinevaid käske võib seega kokku olla 256. Loogiliselt saab korraga, ühe paketiga, anda edasi ühe käsu. 5.bait on järjekorrabait, teatud usb-rakendused kasutavad seda, kuid antud juhul võime seda ise edukalt rakendada. Selle abil saan seadmele teada anda, kustkohast lugema hakata. Ainsaks probleemiks on selle piiratus - näiteks EEPROM mälu on kiibil 1024 baiti, kuid ma saan öelda vaid järjekorranumbri 255. Kahe baidi kasutamisel saaks piirangu tõsta 2^(2*8)-ni, ehk 65536-ni. Minu rakenduses (main.c) saadab arvuti seadmele käsu, ning seade salvestab 5. baidi väärtuse endale mällu. Hiljem saab selle põhjal funktsioonides usb_in(suund seadmest arvutisse) ning usb_out(suund arvutist seadmesse) arvutada andmete asukohakoha. loogik2.zip Kogu lahenduse lähtekood Niipalju siis USB-st. Vahepeal on tekkinud soov tegeleda ka millegi mehhaanilisema, seetõttu hakkan arendama ka arvutile kahest samm-mootorist koosnevat juhitavat turretit. Hetkel on see üsnagi algstaadiumis, kuid edusamme on juba tehtud. Kuid sellest mõni teine kord. |
|
Panen siia kirja pähe tulnud mõtte, et meelest ei läheks. Vaja on saata mikrokontrollerist korraga rohkem kui 8 baiti - see tähendab, et tuleb teha mitu ülekannet. Plaan on teha eraldi käsk arvutist mikrokontrollerisse, mis täpsustab talle, mida ta saatma peab, ning usb_in funktsioon hakkab seda töötlema. Näiteks: Arvutipoolne (1) Ütlen kontrollerile, mida ma temalt tahan ning kui palju (2) Hakkan kontrollerilt infot 8 baidi kaupa vastu võtma(küsima) Kontrolleripoolne (1) Saan teada, mida minult tahetakse ning kui palju (2) Globaalmuutujate abil lükkan "järjehoidjat" iga saatmise korral edasi, saadan korraga 8 baiti Kaval mõte oleks näiteks üks bait pühendada järjehoidjaks, mis kontrollib, et oleks mälus õigel kaugusel, kuid see võib osutuda probleemkseks suuremate ülekannete tegemisel (üks bait võib hoida arvu kuni 255). Lahenduseks sobiks näiteks rekursiivne lugemine. Tuleb meeles pidada, et USB protokolli kohaselt on juht(host), see kes kontrolib kõike. Seade ise saab andmed ainult valmis panna ja loota, et temalt neid nõutakse. Muust küljest: olen mõelnud, et ehk peaks kirjutama veidi vähemtehniliselt. Hea või halb mõte? |

Hoolimata vanameelsete jõudude kriminaalsest käitumisest pealinnas on õnnestunud USBtiny abil saada ATmega88-l tööle USB. Esimesed sammud loogikaanalüsaatori valmimise jaoks on tehtud. Paistis, et probleemid seisnesid kontrolleri ebastabiilsuses, mille vastu aitas Watchdog Timeri kasutuselevõtt. Samuti leidsin uue mooduse andmesiinide pinge vähendamiseks - kontrollerit toidetakse läbi kahe järjestikkuse ränidioodi, mis koos tekitavad pingelangu umbes 1.4 volti. Stabilitronid olen igaks juhuks siiski veel sisse jätnud. Järgnevalt pilt USB piirkonnast makettpaneelil. ![]() Riistvaralisest poolest pole suurt midagi vahepeal muutnud, välja arvatud USB-osa kontrollerile lähemale paigutamine. On ilmnenud, et arvuti ei tunne USB-seadet ära, kui plaadiga on ühendatud programmaator. ![]() Et arvuti tunneks seadme korralikult ära, tuli seadistada driverid, mille genereerisin LibUSB-Win32-ga kaasas oleva programmi abil. Arvutipoolse juhttarkvara tegemiseks valisin Pythoni ning siiamaani on see tundunud õige valikuna. Python kindlustab tarkvara lihtsa ülekandmise teistele platvormidele ning vähendab väljatöötamiseks kuluvat aega tunduvalt. LibUSB kasutamiseks Pythoniga ei kasutanud ma mitte USBtiny-ga kaasas olevat klassi, vaid PyUSB abil välja töötatud eriklassi. Kontrolleritarkvara loomisel esinesid mõningased probleemid, mis olid tingitud minu C-keele puudulikust valdamisest. Hetkel on kontroller seadistatud vastavalt juhttarkvarale kirjutama/lugema EEPROM-tüüpi sisseehitatud mälu. Juhttarkvara kasutusjuhend: python loogikpc.py "2 2 2 2 2 2 2 2" <- võtan puhvrisse arvu 2. Arve peab olema täpselt 8. kood:1 <- kirjuta mällu kood:2 <- loe mälust kood:3 <- välju Siin on kogu praegune loogiku kood, hetkel veel kommenteerimata ning ilustamata. Järgmisteks eesmärkideks oleks teha programmile sobiv graafiline liides, selleks kasutan tõenäoliselt GTK-d või wxWidgetsit. Varsti lisan ka skeemi. |

Idee asi valmistada on juba paar kuud olnud ning sobiva programmaatori saamisel muutus see teostatavaks. Sloveenlane Igor Cesko on hakkama saanud madala kiirusega USB protokolli kandmisega AVR mikrokontrolleritele, mis on juhtumisi ka minu meeliskivid. Esialgne prototüüp sai kokku laotud makettpaneelil, kuid ta ei hakanud tööle. Tõenäoliselt oli tegemist minu sülearvuti USB kontrolleri mitteühildumisega modifitseerimata igorplugiga. Nimelt kuna igorplug võtab toidet USB-st endast ning toitepingeks on 5V, siis on ka USB andmesiini pingeks 5V, kuid USB spetsifikatsiooni kohaselt on selleks 3.3V. ![]() Lahenduseks sai lisada andmeliinidele kaks 3.3V stabilitroni. Järgmine skeem sai tehtud juba püsivam, nimelt jootsin selle makettplaadi külge. Kuna stabilitronide mõte polnud siis veel tulnud, siis jäid need esimesele plaadile ka panemata. Seade hakkas pärast veidikest möllamist lauaarvutis tööle, mille USB kontroller oli siis tõenäoliselt veidi vastupidavam spetsifikatsioonidest mitte kinnipidamisele. Kontrolltarkvarana kasutasin Girderit, versiooniks 3.3. ![]() Mõningase seadistamise järel hakkas seade suurepäraselt tööle minu televiisoripuldiga. Paari päeva laagerdumise järel sai tehtud lõplik versioon, kuhu olid ka stabilitronid lisatud ning mis on mõõtmetelt veidi väiksem ning töötas ka sülearvutiga. Vastuvõtuulatus on üsna suur, vähemalt 5 meetrit ning pulti ei pea ka otse vastuvõtjasse suunama. Järgmisteks eesmärkideks on teha ise kontrolltarkvara IgorPlug USB kasutamiseks ning võimalusel ning aja ülejäämisel ka IgorPlugi funktsionaalsuse kopeerimine USBtiny abil GPL-is ning C-d kasutades. Järgmisteks plaanideks on USB-sse käiva loogikaanalüsaatori tegemine ATMega88 baasil. |

Joy comes in the morning, precisely Sunday March 11th 2007, when I got on a bus and started my trip from Nairobi to Capetown, by road. After months (2) of intensive planning, I started a trip of a lifetime. I have taken leave off work to go off galavanting around Africa to see places we study about. The highlight has to be my day at the Victoria Falls. The falls are the most majestic thing I have ever seen. Because of rains earlier in the year, the falls have a lot of water pouring down the gorge, with a mist that sprays water kilometers into the sky. You can have different views of the falls and view them from different angles, On the Zimbabwe side, the falls are not obscured by the bushes, but views from both countries are AWESOME!! After going round the falls and taking pix, I went to the bridge over the Zambezi River that joins Zambia and Zimbabwe, and did the craziest bunji jump on the planet. I have never been that excited before, the blood rushes to your head, and after the first bounce, you have to scream your head off. But the bunji is not to be repeated because you lose the excitement of the first time. As Sade sings, its never as good as the first time, and I am not gonna spoil it with another jump. I will have to upload pix asap!!! |
