Embedded hardware & software engineer

Hey there! I'm an embedded hardware and software junkie with a master's in automotive engineering and nearly a decade (9 years, to be exact) under my belt in hardware R&D. When you bring me on board, you're not just getting another team member. You're getting a passionate engineer who's all about results, quality, and going that extra mile for you. Welcome to my lab - it's not just my workspace, it's my playground! We're talking full production equipment right here: stencil printer, pick and place, reflow solder machine, and a treasure trove of testing tools. I've got all it needs to take your product from a mere idea to a tangible reality, all under one roof. Here's a sneak peek into my skillset: • Crafting embedded systems designs – PCB design, Altium designer, KiCAD, Eagle • Working with Atmel, Microchip, Espressif and STM microcontrollers • Being the go-to person for Internet of Things systems • Having a soft spot for E-Paper Displays (EPD) (E Ink) • Manufacturing products in-house • Programming in C++, microPython for embedded systems • Running SPICE simulation tools • Exploring Embedded Linux and Raspberry Pi My passion for what I do isn't just a job, it's a lifestyle. I'm all in when it comes to your project, and I've got a track record of hitting deadlines, serving top-notch quality, and being the reliable partner you're looking for. Need an embedded hardware or software guru? Look no further! Send me a message, and let's make magic happen together.

The project is embeddable controller board for LED lights. The board consists of total 16 output channels supporting up to 3A/channel, driven by the microcontroller and LED driver. The controller was developed for a client who is in the advertising business and does a lot of lighting street billboards. Adjusting the working mode of the board is easy, using the onboard 7-segment display and rotary encoder. Board comes with a total of 16 preprogrammed work modes, of which each can be adjusted for duration and brightness. Input is wide range 4V - 24V, which is as well applied to the outputs. Connections to the boards are via standard industrial 5.00mm terminals.

The goal of this project was to design an independent temperature sensor. The device connects to the WiFi network at the defined time interval and submits the temperature data, battery level, date and time to the servers. It is powered by 3x AA batteries which need to be changed every 9 months at time interval od 30min - meaning the device can send data about 13 thousand times before depleting the batteries. It has 3 temperature sensors; 2x DS18B20 and 1x K-type thermocouple. The microcontroller is ESP8266, which is supplied by high-efficiency buck converter. Onboard RGB LED is used to signalise current board status, empty battery, successful data sent. In case there is no WiFI connection or the server to which data is being sent is down, the device will temporarily save the data until connection to WiFi network and server is established. All parameters, including SSID and password, and configured via simple portal. Whole system is packed in a 3D printer box for a prototype series.

The device connects to the WiFi network at the defined time interval and submits the temperature data, battery level, date and time to the servers. It is powered by 3x AA batteries which need to be changed every 9 months at time interval od 30min - meaning the device can send data about 13 thousand times before depleting the batteries. It has 3 temperature sensors; 2x DS18B20 and 1x K-type thermocouple. The microcontroller is ESP8266, which is supplied by high-efficiency buck converter. Onboard RGB LED is used to signalise current board status, empty battery, successful data sent. In case there is no WiFI connection or the server to which data is being sent is down, the device will temporarily save the data until connection to WiFi network and server is established. All parameters, including SSID and password, and configured via simple portal. Whole system is packed in a 3D printer box for a prototype series.

Highly skilled, understanding & committed. Did the hard parts of the work straight ahead.I highly recommend them & would for sure hire them again soon. The project was about data capture & transmission using the NRF signal, data capture & reproduction libraries was fully created by eradionicacom & it worked perfectly.
