To je pouze estetická vada, vlnám to nevadí - úhel odrazu se pořád rovná úhlu dopadu. Při podrobném zkoumání střech či jiných vhodných lokalit na takto umístěné paraboly občas narazíte.Ja vim. Problem je, jak offsetovou parabolu nasmerovat. Jak zjistim, jak moc ji mam naklonit? U stredove paraboly to bude jednodussi.

}Ak máš k dispozícii nejaké staršie SDK vytiahni si z nich fwsplit a ubnt-mkfwimage ,
ale budeš musieť upravovať trocha ich zdroják s novšími fw si neporadia.
.bin súbor má 4 časti ubot, kenel , rootfs a scripts
zaujíma ta rootfs na neho budeš potrebovať squash fs tools .
5.6.5 som ešte upravovať neskúšal , ale na starších verziách to funguje.

zkus misto oklesteneho Lubuntu nahodit Xubuntu (alespon na zkousku jetli trvas na LXDE)...
mam Asus EEE 1008HA, jde snad o to same (jen ma kryte konektory, interni baterku a je placatejsi) a s Xubuntu 14.04 out-of-box chodi:
LCD Jas +/-, Vol +/-, Wifi on/off(Fn+F2 i samostatne nad ESC), LCD config(Fn+F8), Sleep (Fn+F1)
takze jedine co nejde je blokovani touchpadu a Fn+Space(power profily??)
Na jednom konci vrazíš VGA a USB do komplu a na druhém máš na ethernetovém kabelu v paketech nějak zabalené to, co tam ten kompl zapsal. A naopak, když do toho ethernetu pošleš správně udělanej paket, tak něco vyleze z toho USB. Nečekej od toho inteligenci, ta je v tom KVM switchi ke kterému ten kabel patří.
Nevím, jestli je to to pravé, ale určitě bych takovou věc nevyvíjel, snažil bych se koupit hotový alespoň hardware :-)
