<r>Update on the radio mentioned in another thread. Got the ferrite antenna sourced (thanks sa community tip on Deeco Surplus, found one).<br/>

<r>Asked by my nephew kung worth ba yung Fluke price tag para sa hobby. Owned both for years, eto yung totoo:<br/>

<B><s>[b]</s>Where Fluke wins:<e>[/b]</e></B> input protection, AC current accuracy at low frequencies, the reassuring "click" of test leads na hindi malayong sablayan. Built like ...

<t>Yung T12 iron talagang well-priced para sa quality. Mas mabilis mag-init kaysa yung mga old-style Hakko clones, mas precise yung temperature control.<br/>
<br/>
For PHP 1500, kayang-kaya. Specifically: yung KSGER T12 station with a few tip variants (chisel, conical, knife), around PHP 1200-1400 ...

<r>Tinanong ako ng kapatid ng kaibigan kung paano daw mag-basa ng schematic. Anak niya, 2nd year EE, daw confused. Realized maraming beginner ang nag-build ng circuits without really understanding the symbol system.<br/>

<r>For a beginner, ano talaga yung difference? Cheap UNI-T or Aneng vs Fluke 117, yung pera mahal lang ba dahil sa brand, or may real differencia?<br/>
<br/>
Sa career ko nakapag-handle ako ng tatlong meters, first was a Yoke meter from Raon noong 1989, second a Sanwa, current Fluke 117. Mga ...

Tito Elmer dito. Retired mechanical engineer, hobbyist tinkerer ngayon. Iba na talaga yung electronics ngayon kumpara noong nag-aaral kami sa MIT-Manila noong 80s. Pero yung mga basic principles, di nagbabago. Nire-restore ko ngayon yung lumang transistor radio ng tatay ko, see other thread.

<t>Maganda yung writeup sa L298N. Adding from years of using these:<br/>
<br/>
Yung L298N may bad reputation kasi binabra-abuse ng mga tao. Pag respeto mo yung limits (2A per channel max, 4A combined), malinis yung heatsink at properly thermalled, hindi mo i-run past 80°C, easily 5+ years yung ...

<r>Dating embedded engineer dito. Ginawa ko ito noong AVR pa lang yung choice for hobbyists. Tama yung plan mo: Timer 1 for motor PWM, leave Timer 0 alone for delay/millis.<br/>

<r>Ay sayang, ang dali-dali nang mag-Arduino ngayon. Noong panahon ko, parallel-port programmer at AVRDUDE manually pa. Tatlong oras pa ako mag-troubleshoot ng same kind of error.<br/>

Tama si Mark, CH340 driver yung first thing to check. Pero may isa pa akong tip na hindi pa nababanggit:<br ...

<t>Magandang araw mga kapatid. Nire-restore ko yung 1970s Sanyo AM transistor radio na nakita ko sa lumang tool chest ng tatay ko. Yung original ferrite rod antenna nito, sira, nakacrack siya in half, parang nadagan or nahulog dati.<br/>

Noong panahon ko, makakakita ka ng ganitong parts kahit ...
