Desigur, la aceste 5.7 grame se vor mai adauga 0.5-0.6, constand in antena dipol pentru banda de 14 MHz, care va fi confectionata din sarma de cupru de 0.1mm, suspendata cu ajutorul unui fir de pescuit de 0.08mm.

Transmitatorul va opera in banda de 14MHz, moduri de lucru WSPR si JT9, frecventele clasice.
Transmisia are la baza un ciclu de 6 minute, care debuteaza la minutele 2, 12, 22, 32, 42, si 52 ale fiecarei ore.

Minutul x2 - 20m JT9 - Indicativ + locator 6 caractere
Minutul x3 - 20m JT9 - Caracterele 7+8 ale locatorului extins + Altitudine + Viteza de deplasare in plan orizontal (km/h)
Minutul x4 - 20m WSPR - Mesaj WSPR standard
Minutul x6 - 20m WSPR - Telemetrie speciala WSPR

Soft-ul este inca in dezvoltare. Voi reveni cu alte detalii.

Edy, esti mai rau decit femeile! La tine fiecare gram in plus conteaza, hi!
Intrebare: daca balonul nu se sparge, de ce este important atit de mult fiecare gram in minus?
Ma gindesc ca nu se sparge, caci n-ar avea timp sa dea tura completa. Mai usor deasemenea inseamna mai sus, pina cind se ajunge la un echilibru. Softul in ce limbaj este?

Salutari!

Fiecare gram in minus inseamna heliu mai putin -> mai mult volum disponibil pentru expansiunea gazului -> presiune mai mica in balon -> sanse mai mici de a se sparge.

Nu este inca in aer, totul este pe planseta. Edy descrie in felul sau cum se materializeaza un viitor proiect: ocolul pamintului cu un balon cu heliu. Frumos proiect, chiar interesant.

Testele continua, fiind foarte aproape de varianta finala a softului. Au aparut pe parcurs anumite mici probleme care au necesitat minore modificari ale cablajului imprimat.

Din cauza vremii, abia astazi am reusit sa demarez cu adevarat testele solare. Maine, 25 aprilie voi face un test pe durata intregii zile, la orizontala. In poza este pus intr-o pozitie de test.

Salut Edy

Cind ajungi la o versiune finala, care te multumeste din toate punctele de vedere ar fi minunat sa o faci publica. Chiar daca nu este montata pe un balon, ea poate fi folosita ca baliza in unde scurte. Poate fi montata pe antena sau linga antena, direct in gradina, si pentru ca se alimenteaza de la soare, face ca totul sa fie complet independent energetic. Iti urmaresc in continuare proiectul si la momentul oportun o sa fac si eu o incercare. Succes!

ICT1 a mai slabit putin. Noua revizie a placilor a sosit ieri din China. Acestea au 13x28mm plus urechiusele de prindere. Laminatul este tot subtire, cel de 0.6mm.

Rezultatul a fost o reducere de aproximativ un gram, precum si functionalitate crescuta datorita unor componente ce nu se regaseau in vechiul proiect : un comutator high-side pentru a putea opri emitatorul si un supervizor de reset pentru microcontroller.

Indicatia lui Mike SA6BSS este ca pre-presurizarea sa fie facuta pana aproape de 0.7-0.75 psi dar, neputand sa ajung pana acolo, ideea intiala era ca manometrul meu diferential indica eronat.

In urma unei verificari cu instrumente de mare precizie, ipoteza s-a dovedit a fi falsa. Testele au aratat ca in intervalul 0.16 - 0.74 psi eroarea maxima de masura este de doar 0.01 psi. Asadar, urmatoarele incercari de pre-presurizare se vor plafona la maximum 0.6 psi presiune diferentiala.

Procesul s-a desfasurat in conditii de temperatura crescuta, aproximativ 30-31 grade Celsius, a durat aproximativ 3-4 ore, si s-a atins o presiune diferentiala maxima de 0.61 psi. Volumul balonului a crescut considerabil, cu aproximativ 30-35% dupa unele estimari.

Aerul a fost apoi extras din balon, iar acesta a fost pus la pastrare intr-un sac de vidat haine impreuna cu doi saculeti de silicat, in vederea lansarii.

Te rog daca se poate sa ne dai mai multe details legate de balon:
- material, grosime, greutate, dimensions (volum)
- cum faci etansarea dupa ce este umplut cu gaz
- folosesti heliu din cel disponibil comercial (pentru baloane de petreceri) sau heliu de puritate crescuta
- cum calculezi cat heliu sa introduci in balon
- este comandat special la ceva furnizor pe dimensiuni date de tine, sau sunt baloane standard
- pret, furnizor

Salut,

Baloanele sunt standard, din PET. Au aproximativ 35.5 grame din care reusesc sa reduc inca un gram taind cu foarfeca excesul de material de pe margini. In starea in care vin, au aproximativ 0.1 mc volum, iar diametrul este de aproximativ 36 inch.

Etansarea dupa ce se umfla am realizat-o cu super glue gel la ICT1. ICT2 va fi etansat la cald, cu fierul de calcat.

Heliul este cel pentru baloane de petrecere, dar cel de puritate ridicata. Atentie, unele magazine ofera 80% mix heliu-aer.

Nu calculez cat heliu bag, ci ce masa trebuie balonul sa ridice : masa incarcaturii + portanta libera. Confectionez un obiect cu exact aceeasi masa pe care il atarn de balon. Cand ansamblul este in plutire perfecta, ma opresc din alimentat cu gaz si sigilez balonul.

Furnizor : Aliexpress, ~1.2$ balonul.

Mulțumesc pentru precizări.
Înseamnă că nu ai prea multe variabile asupra cărora poți să acționezi. Pentru a determina o anumită altitudine de zbor de ex.
Mă gândesc că o altitudine de 12 - 13 km ar fi de preferat uneia de 9 - 10 km.
Cum ar fi:
- să folosești două (sau trei) baloane în loc de unul
- să folosești H2 în loc de He
Nu ai putea obține o altitudine de zbor mai mare așa? Sau să-ți permiți o încărcătură mai mare? Ex:
- încă un minipanou solar la 90grd -> perioadă de emisie mai lungă în fiecare zi
- să tratezi (cu ceară) exteriorul baloanelor, etc
Și mai am o întrebare:
Ce teste faci / poți face înainte de lansarea propriu-zisă? De exemplu pentru a determina altitudinea la care va zbura.
Succes cu ICT2!

Nu exista foarte multe variabile aici.

12-13 km este aproape imposibil de obtinut cu baloanele chinezesti.

In anumite limite, punctele mentionate de tine sunt valide, dar nu este atat de usor. ICT2 va avea doua baloane.

Ca teste, pre-presurizez baloanele ca sa evit defectele de fabricatie si le maresc usor volumul, de la 0.1mc pana aproape de 0.13mc.
