Attended an amazing webinar by @alifsemi & @EdgeImpulse on boosting AI model accuracy with retraining, transfer learning & synthetic data.
Excited about the MCU series Alif is producing - can’t wait to work with it! 🚀

That feeling when a new sensor won’t work…
You triple-check wiring, watch the same YouTube video 5x, still nothing.
Next morning: turns out it was just the library version 🤦🏽♂️
#embedded#iot#electronics#smartfix
Built an automated pedal system for a Mech. Engineering student:
🔹 Arduino Nano
🔹 BTS7960 driver
🔹 Pot pedals (accel + brake)
🔹 24V from LiFePO4 batteries
Shared the code last Saturday, now showing the hardware
#arduino#embedded#lifepo4#automation#smartfix
Should devs put stopcodes in firmware/EEPROM to disable devices if clients don’t pay?
✅ Protects devs, ensures fair compensation
⚠️ But feels like “locking out” owners of hardware they bought
A logical business move or ethical red flag?

Writing a program for a driving automation project (pedal + BTS7960)
Arduino IDE forgives you for defining functions late.
PlatformIO? Nope! you must declare before use or face errors
The shift makes you structure code better, a better interface to arduino ide
#embedded#arduino
One-layer PCBs are like a puzzle
Every trace: you don’t touch, don’t cross, squeeze through.
Frustrating? Yeah....
But great for quick side projects, low cost - and they force you to think sharper about routing & design
#embeddedsystems#pcb#esp32#electronics#smartfix
In electronics, specs & part names don’t need cramming
Build, fail, fix, repeat… and it sticks
I was mixing up AC vs DC back in early years at uni, now it’s second nature
So, Hands-on really supercedes theory alon
#engineering#smartfix#Electronic#embeddedsystems#biomedical
Embedded with Fun vibesss 😂
Took a break from the fall detection program when Matlab wasn't responding...smart dice looks nice, but it's high time I ran back to the fall detection device 😌
#embeddedsystems#Arduino#smartfix#esp32#technologia
Consistency is everything in embedded systems
Try a library → fail
Change wiring → fail
Frustration → real 😂
But every “doesn’t work” sharpens familiarity, and
Hands-on teaches what theory can’t
That’s how AC vs DC finally made sense to me.
#engineering#embedded#electronics
Engineering is money laundering… but for skills. 💸
Every course, tool, and software is an expense; until you look back and realize you’ve been laundering cash into knowledge all along.
Worth it? Absolutely.
...Sunshine DT-17N 😪
#Engineering#EmbeddedSystems#GrowthMindset
Working on a SIM800L today & saw the library has built-in over-voltage detection + auto shutdown
Good firmware libraries = less “talking to the metal,” more time building features.
Abstraction isn’t laziness — it’s speed, safety & focus.
#embedded#firmware#iot#electronics
Uno: Compiles in seconds ⚡️
ESP32: “Go make coffee” while it builds ☕
This is why;
Bigger firmware
RTOS & drivers
Complex toolchain
But… ESP32 gives you Wi-Fi, BT, dual-core CPU, more RAM & GPIOs
Slow compile. Fast device. Worth it.
#ESP32#IoT#Arduino#EmbeddedSystems
Arduino IDE → PlatformIO
I still love Arduino IDE for quick tests, but PlatformIO is a game changer:
✅Clean multi-file projects
✅Auto library mgmt
✅Advanced debugging
✅Multi-board support
Tools make up your embedded-system skills
#IoT#PlatformIO#Arduino#embeddedsystems
Fall Detection Device
Schematic + 3D PCB outline ready!
It includes ESP32, MPU6050, SIM800L…all through-hole & compact
My next process will: routing + firmware
