Re: 🤖 Circuitrocks Supports IECEP QCU Robotics Wars 2026 — Empowering Future Robotics Engineers

Late na ako pero hindi pa late: support sa RoboWars sa UP-NCR! Yung circuitrocks parating reliable sponsor for these events. Last year nag-set up din kami ng team — yung sumo arena setup hardcore.

Sino mag-aattend ng coming year edition? Bring na ko ng team.

Re: 🚀 Circuitrocks Sponsors SQUEEZE 2.8 at UP Circuit

Attending kami nito! Yung UP Circuit consistently good organizers pa naman. Sino dito sa forum balak attend? Pwede magkita-kita.

Yung last year SQUEEZE — may table na tinatakbo ng circuitrocks din ba? Nag-stop ako sa booth nila for components.

HC-SR04 max practical range outdoors — ano experience niyo?

<t>Datasheet ng HC-SR04 sabi 4 meters max range, lab conditions yan I assume. For our outdoor obstacle course (sumo bot territory border detection), kelangan ko ng reliable detection at 2 meters minimum.<br/>
<br/>
May nag-test na ba ng HC-SR04 sa real outdoor conditions? Wind, surfaces of different ...

JM here, robotics captain

3rd year competing — sumo bots and line followers mostly. Posting late kasi yan yung work hours namin sa robotics lab. Sa veterans dito — daming napupulot. Sa mga junior na kasama ko sa lab, redirect ko sila dito kapag may tanong na hindi ko alam yung sagot.

Re: Servo motor keeps jittering even at rest — 4 things I check before blaming the servo

<r>Confirmed yung decoupling cap fix from competition robotics experience. Niligtas niyan yung line-follower namin last season — yung dalawang MG90s sa front jumitter nonstop, halos sumuko na ako bago ako naglagay ng 220µF + 0.1µF across each servo's power input. Suddenly stable.<br/>

Re: ESP32 vs Pi Pico W for IoT thesis — which is more reliable for 24/7 data logging?

<r>Sa robotics team namin, ESP32 ginagamit for telemetry — 4 hours of continuous bot ops, sends IMU + battery data every 100ms over WiFi. Crash rate near zero, pero kasi maikli yung sessions namin — hindi yan yung deployment scenario na tinatanong mo.<br/>

Increasing PWM frequency on Arduino Uno for sumo bot — anyone done direct register manipulation?

<r>Bumubuo ng 1kg sumo bot for inter-college comp soon. Default Arduino <CODE><s>[code]</s>analogWrite()<e>[/code]</e></CODE> runs PWM at around 490Hz on most pins, kaya may audible whine yung motors namin. More importantly, hindi maganda ang ramp-up ng speed.<br/>

Alam ko kayang i-manipulate ...
