Hi, my name is Aljaz Titoric and I'm a hardware engineer
Maker | Creator | Developer | Technology Enthusiast | Electrical Engineer
I devoted my childhood to disassembling of electronic devices and playing with their components. In secondary school, I familiarized myself with the technology of designing and etching PCBs, spent my teenage years with a soldering iron and developed a student website Elektronika-start [in slovene] where I published many hobby projects in hopes to help young aspiring engineers. I studied at the Faculty of Electrical Engineering in Ljubljana. In Slovenia I worked as a HW design engineer in several different companies. Currently I’m working for a high tech company ASML from Nederlands – semiconductor industry. My job is hardware design of the high voltage power supplies which are used for driving AC motors inside the photolithography machines. In recent years I have specialized in the design of printed circuit boards with Cadence OrCAD and Altium Designer and I use SolidWorks for enclosure designing. In the coming years I aspire to continue working in tech, both professionally and as a hobby.
Currently, I am located in Eindhoven, Nederlands.
Movement data logger
In my student years I came up with an idea to develop a device that would detect the dynamic forces of kayak sprint. The circuit board is based on the Microchip Cortex M0+ MCU with an accelerometer BNO055 from Bosch Sensortec, SIMCom SIM39EA GPS receiver, Polar RMCM01 hearth rate monitor, HM TRP-868 868MHz RF transmitter, 2,7″ Sharp memory LCD LS027B7DH01 and uSD card reader. RF transmitter enables the transfer of captured data on a personal computer, which analyzes the movement of the kayak. The 4lay single sided PCB’s size is 70x50mm. On the other side of the PCB is a mounted LCD screen. The device is powered via Li-Ion battery with autonomy up to 20 hours of usage. The battery status measurements are done via fuel gauge monitor MAX17043G+U from Maxim Integrated. The waterproof enclosure is made from plastic with mounting pod that enables the placement of the device on different surfaces.
Terminal Board TBv2
I have worked on a bigger input/output board on which we can connect peripherals such as: linear actuators, key switches, LED diodes, buttons, DC motors, RGB LED strips, etc.. The connections between the board and peripherals is done via 72pin CardEdge connector. The circuit board is based on the NXP LPC11E67JBD100 Cortex M0+ uC and contains a few different communications: UART, MDB, I2C, SPI, USB, 1-wire, ccTalk etc.. My tasks included schematic and layout design, selection of components and drawing the symbols and footprints. The single sided 4 layer PCB contains over 400 SMD and THT components.
Project e-treadmill @Volkswagen Slovenija
The Volkswagen Slovenia (general sponsor of Volkswagen 23rd Ljubljana marathon) set the goal to offer the runners the possibility to generate the electrical energy whilst running. As an electrical engineer I was part of the team who has developed the e-treadmills. My assignment was to deal with electrical parts of the project. I have developed the 10 channel LED current indicator and charging circuit for 12V batteries. The converted electrical energy will supply the camera equipment for making the TV video spot (the commercial).
IOM6-ActiveProbes @iSYSTEM Labs
iSYSTEM Labs is developing a new family of products called Active probes. Their purpose is debugging and tracing the code in the microcontrollers. My assigment was the design of the black anodized aluminum enclosure, that has the cooling function for the device. Alongside the enclosure design I was also in charge of designing the mulilayer PCBs (8-10 lay) with 400-550 components. The heart of the circuit is the Xilinx’s FPGA with 676 pins in BGA package. The PCB contain high integration of components with high speed differential pairs.
IOM6 Add-On-Modules @iSYSTEM Labs
iSYSTEM Labs is developing a new family of products called IOM Add-On-Modules.They are used for capturing the data between two or more microcontrollers (CAN, LIN, ethernet and other comunications). My work was designing the metal sheet enclosure and the multilayer (6-8 lay) PCBs with 450-700 components. The PCBs in question contain high integration of components with high speed differential pairs.
Dental testing unit: PCB @C&C design
Both schematic and printed circuit board for electronic dental testing unit model DTU-1000 were designed from scratch. The device makes it easier to test and repair the dental handpiece and its micro motors. The 4lay circuit contains switching, linear and DC/DC isolated power supplies. Its core is a 32 bit Cortex M4 MCU from Microchip. The circuit board controlles 9 relays on which the electromagnetic valves for air and water are attached. My tasks included the schematic and layout design, the selection of components, drawing of libraries, assembling and testing the boards and ordering the material.
Dental testing unit: Enclosure @C&C design
For the DTU-1000 enclosure we chose the OKW modular enclosure and added CNC milled 2mm aluminum front and rear panels. I was in charge for the customization of mechanic parts, graphics and device’s user interface, the latter included the layout of buttons, switches, LEDs, flowmeters, manometers and other parts of the device.
Custom PCB Layouts @Torqbyte
In cooperation with the company Torqbyte we have created a couple of different custom PCB layouts 2-4lay that are going to be used for prototyping and testing purposes. The printed circuit boards are designed to be manually or mechanically assembled.
Raspberry Pi CM4 Control board
ASML EXE5000 EUV Photolithography machine
Project VW car show @Agencija 101
In cooperation with the company Agencija 101 we created an interactive advertisment for Volkswagen. The task was to produce a trigger for avdio/video player on a large (7x3m) LED display. The core of the project is based on Linux operating system that runs on Raspberry Pi platform. The video was activated via PIR sensor and a touch sensitive floor mat. The assignment was to develop both hardware and software. The project was presented at the Avtosalon Ljubljana 2017.
Ljubljana Hardware Meetup
I am an organizer of the Ljubljana Hardware Meetup Group. The group was formed in hopes to spread the knowledge among Slovenian electrical engineers, software developers and other tech enthusiasts. The events are held on a monthly basis in Ljubljana. On our first Meetup event, I spoke about designing the multilayer PCB, defining the board’s stackup, signal & power integrity and power delivery networks.
Electronics / Hardware Talks Eindhoven
I am an organizer of Electronics / Hardware Talks Meetup group in Eindhoven. We started the series of events in wish to connect electrical engineers in Eindhoven – The Netherlands.
Events are comprised of lectures from engineers and academics and is also meant for networking.
My work includes hosting, speaking, meeting with other speakers and website maintenance.
In partnership with Altium Designer we prepared a technical article related with electronics and hardware design with name “Closing the gap between Electronics (ECAD) and Mechanics”.
