Omo, if anybody tells you that hardware engineering in Nigeria is easy, the person is actively whining you. See, my client all the way in Lagos hit me up for a custom biometric attendant system and that was when I knew it was time to cook. From my workspace here in Abuja to Lagos, let me show you how we built this beast. First things first, right? It's the anatomy. We're not doing anything basic. The brain of this operation is ESP32 because you need that Wi-Fi to push the attendance straight to a Google sheet dashboard. We pair it up with the fingerprint module and RTC for accurate timing and has SD card module so that even if the network is acting up, nobody's attendance is going to get lost. There's no excuse for the project not to work. Now, wahala for who dey use jumper wires to ship final products, do you want the client to sneeze and the whole system will reset? God forbid. Because of that, I had to link up with one of my guy, SiliconPulse CEO. We sat down, routed the traces, designed the custom PCB for this specific build. Look at that board, clean, professional and solid. Teamwork makes the dream work, literally. You cannot build a Rolls Royce engine and put it inside a pure water nylon, right? So because of that, we designed a custom 3D enclosure and the 3D enclosure was designed in a way that is going to house the 16x2 LCD display and the 4x5 matrix keypad and the scanner perfectly. So we printed everything out and bolted everything in and guys, just look at the finish, the tolerance, perfect, the aesthetic, 100. But hardware without software is just fine plastic. We wrote the firmware to handle T9 multitap on keypad so that new users can type their name just like the old Nokia 3310 days. You place your finger, the buzzer goes beep and boom, it logs your name, time and date straight to the cloud. Tested and trusted and ready to move. We packaged it securely, took it straight to ABC Logistics and shipped it off to Lagos. From Abuja to the world. If you need custom hardware, IoT systems or just like seeing cool tech builds, hit that follow button and we are just getting started because we outside.
