Electrical Engineer Ka PCB Design Journey: Circuit Simulation Se Income

Short answer: Electrical engineering degree ke saath PCB design freelancing shuru karne ke liye KiCad (free tool) seekho, 2-3 personal projects banao dikhane ke liye, aur Upwork ya Fiverr pe apply karo. Chhote projects ₹3,000-8,000 mein milte hain, complex multi-layer boards zyada. Simulation software (LTspice, Proteus) bhi zaruri hai design verify karne ke liye.

Layoff email aaya ek Friday shaam ko, 6:47 baje. HR ka call bhi nahi tha, sirf ek email jisme likha tha "role eliminated due to restructuring."

Do saal us company mein diya tha, hardware team mein. Do mahine ghar pe baitha raha, applications bheja, kuch interviews diye, kuch mein reject hua. Ek raat frustration mein apna purana college laptop khola, wahi jisme LTspice install tha, aur ek circuit simulate karne laga jo bas dimaag khaali karne ke liye tha.

Wahi raat samajh aaya ki ye jo main free mein kar raha hoon, log isi ke liye paise dete hain.

Pehla project jo kabhi finish nahi hua

Pehle try kiya seedha bada project lene ka, ek complete IoT device ka PCB design. Client ne Upwork pe post kiya tha, budget ₹18,400 tha.

Apply kiya, mil bhi gaya. Par 3 hafte mein realize hua ki main overestimate kar gaya tha khud ko. Multi-layer board tha, power management complex thi, aur client baar baar requirements badal raha tha.

Project cancel karna pada 60% completion pe. Client ne partial payment di, ₹7,200, par relationship kharab hua. Us din bahut bura laga, laga shayad ye kaam mere liye nahi hai.

Chhota shuru karna, jo actually kaam aaya

Doosri koshish mein bilkul chhota project liya, ek simple LED driver circuit ke liye single-layer PCB. Budget sirf ₹3,500 tha, par scope bhi chhota tha.

2 din mein khatam kar diya. Client khush tha, 5-star review diya. Isse confidence wapas aaya.

Waise, mujhe lagta tha chhote projects "waste of time" hain, kam paisa milta hai. Baad mein samajh aaya chhote projects reputation banate hain, aur reputation hi bade projects laati hai.

Simulation ka role, jo maine underestimate kiya tha

Shuru mein socha tha PCB design matlab seedha layout banana, simulation sirf college ke liye hoti hai. Galat tha.

Ek client ke liye power supply circuit banaya tha, simulation kiye bina seedha layout bana diya. Board manufacture hui, physically test kiya, aur voltage regulation sahi nahi tha. Rework karna pada, extra 4 din lage, aur client ka trust thoda hila.

Us project ke baad rule bana liya: koi bhi circuit, chahe kitna bhi simple lage, pehle LTspice mein simulate karo. Isse manufacturing ke baad ke surprises kaafi kam ho gaye.

Ek client jo bahut specific tha, aur jo maine seekha

Ek Australian client tha jo har cheez documented chahta tha, schematic se lekar bill of materials tak, sab kuch detailed. Shuru mein frustrating laga, itna documentation kyun chahiye ek chhote project ke liye.

Par uske saath kaam karte karte maine proper documentation practice seekhi, jo ab har project mein use karta hoon chahe client maange ya na maange. Ye habit hi hai jo mujhe doosre freelancers se alag karti hai ab.

Us client ne mujhe 4 aur projects diye 7 mahine mein. Total earning uss ek client se roughly ₹34,600 hua.

Portfolio jo pehle client se pehle banaya

Kisi ko bhi trust nahi hota kisi naye freelancer pe sirf resume dekh ke, especially hardware ke kaam mein jahan physical proof matter karta hai. GitHub portfolio banake clients convince karna sirf software developers ke liye nahi hota, maine bhi yahi kiya, apne schematics aur simulation results GitHub pe daale.

Ek chhota repo banaya jisme 3 projects the: LED driver, Arduino shield, aur power supply board. Har ek ke saath simulation screenshots aur final PCB photos daale. Pehla client ne yahi repo dekh ke hi mujhe shortlist kiya tha, baad mein unhone bataya.

Abhi ka setup

Roz ka schedule fix nahi hai, project ke hisaab se badalta hai. Simulation aur design mein roughly 60% time jaata hai, baaki client communication, testing, aur documentation mein.

Mechanical engineers jo CAD freelancing karte hain, unka process bhi kaafi similar hai, bas software alag hai. Aur AutoCAD freelancing mein international clients dhundhne ka jo approach hai, wahi mujhe bhi kaam aaya shuru mein.

Ab poora time freelancing pe hoon, job wapas nahi li. Family thoda pareshan tha shuru mein, "stable job chhod ke ye risk kyun," par 9 mahine ho gaye hain aur income job se dheere dheere close aa raha hai, kabhi kabhi ek mahine mein usse zyada bhi ho jaata hai.

Sabse achha part ye hai ki ab main sirf wahi projects leta hoon jo mujhe genuinely interesting lagte hain. Job mein aisa possible nahi tha, jo assign hota tha wahi karna padta tha. Ab agar koi project boring laga, seedha mana kar sakta hoon, aur ye freedom kisi bhi extra income se zyada value ka lagta hai mujhe...
