<div class="moz-cite-prefix">Mne sa tie micrel obvody zapacili prave
preto, ze na "blikace" netreba viac ako par milimetrov stvorcovych
a vacsinou to zabera menej miesta ako pripojena baterka. A kupoval
som to na ebay-i od jedneho americana co este v tej dobe posielal
bez postovneho a nejakych 100-200 kusov tak vyslo na ozaj par
euro. Ak chcete, mozem par kuskov odstrihnut a poslat, to by bolo
asi najrozumnejsie...<br>

<div>Obidva typy vyzeraju velmi dobre, az na to, ze z Farnela je
treba zaratat 4,90... :( Co teda dost favorizuje tunajsi GME s
vyhliadkovou jazdou z jednej stvrti do druhej a spat.<br>

<div>Druha vec je, ze tu 555 strcim do univerzalu, kdezto
sot23-5 je uz trochu smd ostara, navyse, ked treba robit
guard-ring. Ale inak si myslim, ze ten micrel vyzera velmi
dobre a keby bol v dip puzdre, tak by bol v aplikacii
vhodnejsi nez 555.<br>

a MIC1557 (astable). Idu od 3V do 18V, prva strana
