<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 ...

Magandang araw mga kapatid
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.

Re: L298N mainit sobra at slow yung motors — paano mai-improve?
<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 ...

Re: Increasing PWM frequency on Arduino Uno for sumo bot — anyone done direct register manipulation?
<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/>

Re: Hi po, first time mag-Arduino — bakit hindi nag-uupload yung sketch ko?
<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 ...

Restoring an old transistor radio — sourcing ferrite rod antennas locally
<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/>
