Hardware, CAD & Embedded

A collection of scripts and tools for the few still-made 5V programmable logic parts (Atmel ATF150x, GAL). Unlike modern FPGA toolchains it focuses on legacy 5V logic: the practical way to program these rare parts in retro and repair projects.

A development kit for running models on industrial edge hardware. Unlike Raspberry Pi-class boards it targets certified industrial equipment — which is what a factory floor requires.

A thread accumulating hardware notes and firmware dumps for one camera SoC (AK3918). Rather than vendor documentation, which does not exist, a single issue thread is usually the only source for models like this.

Custom firmware for Anyka-based cameras. Unlike OpenIPC it targets this family, which OpenIPC does not cover — and most cheap Chinese cameras use it.

A coin-sized RISC-V Linux board with 64 MB RAM, MIPI camera, SPI display and Wi-Fi. Running full Linux rather than a microcontroller at that scale is what makes it unusual.

An article summarising the AvaotaF1 board’s specifications and likely uses. Unlike diving into the official repo, it introduces the board in a few minutes — a quick first look.

A resource list for Adafruit IO, visualising and storing data from any device. Unlike general IoT platforms, it integrates directly with Adafruit hardware and libraries and is hobbyist-friendly.

A resource list for Bluetooth Low Energy, low-power wireless communication. Unlike classic Bluetooth resources it focuses on low-power use; the list gathers stacks, libraries and debugging tools.

A list of hardware, protocols and platforms for the Internet of Things. Unlike general embedded lists it weights the connectivity and cloud side — MQTT, LoRa, device management.

A list of tools and resources for MQTT, the IoT connectivity protocol. Unlike HTTP it uses a lightweight publish–subscribe model; the list gathers brokers, clients and tools.

A list of hardware projects with openly licensed designs. Unlike product catalogs it points to projects whose schematics and PCBs you can read and build on.

A list of Raspberry Pi projects, operating systems and hardware add-ons. Unlike forum threads it is a tidy, categorised starting point.

A list of free and open tools for professional robotics development. Unlike general robotics lists it focuses on a production-grade toolchain — testing, logging, visualisation.

A list of libraries, simulators and learning resources for robotics. Unlike single-platform lists it maps the whole field from ROS to control theory.

A browser tool generating CAD models from text, reaching into CAM as well. Aimed at simple parts without drafting skill, not at precision engineering.

An electronics component distributor with a strong catalogue, datasheets and parametric search. Against other distributors it wins on stock depth and single-unit sales — buying one part for a prototype is unremarkable here.

Keeps device state server-side as a digital twin. Unlike MQTT brokers that only relay messages it stores state, so the last known state stays queryable and commands queue up even while the device sleeps.

Circuit simulation with real-time animation, working on mobile as well. Against Falstad it offers a touch interface and lets you drag component values and watch the result change immediately.

A large tutorial repository for the Flipper Zero covering apps, hardware add-ons and usage. Unlike the official docs it goes into community projects: practical, video-backed guides that also cover accessories like SAO badges and the FlipBoard.

Projects that introduce FPGAs through hardware description languages, each producing a working circuit. Unlike a university course it starts from the project — something that works before any theory.

A parametric 3D CAD modeller where you go back up the design tree and change a dimension. That parametric approach is the split from Blender: Blender sculpts polygons, this designs a manufacturable part.

A shared tracked robot platform model — a way to start from a working design instead of drawing chassis geometry from scratch.

Open-source Turkish repository of technical resources and tools for unmanned aerial vehicles (UAVs), autonomous systems, and embedded avionics; organizes structured engineering references instead of scattered competition notes.

The automation engineering society, awarding certificates against the IEC 62443 industrial cybersecurity standard. Unlike IT security bodies it addresses operational technology, where the priority is not confidentiality but continuity.

An open-source suite covering the whole electronics design flow from schematic to PCB layout. Against Eagle and Altium there is no layer count or board size limit — no free-tier ceiling at all.

A full lecture series on control theory — transfer functions, stability criteria, state space. Unlike practice-oriented videos, it builds the mathematics in academic order.

The engineering-intuition side of control theory: how you actually tune a PID, what noise and saturation do to it. Unlike the academic lecture series it offers intuition rather than formulas — the two belong together.

Embedded libraries and firmware repositories weighted towards USB HID and wireless input devices. Unlike general embedded libraries it has that focus — a reference for controller and keyboard protocols.

An industrial parts catalogue where nearly every item has a downloadable CAD model. Unlike general shops, those models and dimension tables make it a reference whenever a design needs a real bolt’s measurements.

A search engine for electronic components that compares stock and price across distributors on one page. That is what saves you checking Digi-Key and Mouser separately — you see availability while still designing.

Parametric CAD entirely in the browser, working on a database rather than files, so branching and merging behave like Git — something SolidWorks does not offer.

A book of high-resolution cross-sections of electronic components, showing the insides of resistors, capacitors and connectors. Against datasheets it shows how a component is made — the abstract symbol becomes a physical object.

Open firmware for IP cameras that removes the vendor cloud and exposes the RTSP stream directly on your own network. Unlike the vendor firmware, it lets you run the camera without putting it on the internet.

Moves between camera firmwares and back to stock. Compared with flashing by hand over a serial cable it is safer — often the only recovery tool you have while experimenting.

The supported chipset list and build instructions for open IP-camera firmware. Unlike the vendor firmware it does not depend on a cloud; check whether your camera’s SoC is on the list before you buy.

The flashing steps and, more importantly, the way back. Attempting this without a serial console raises the bricking risk considerably.

A remote-controlled airsoft turret where embedded control, video streaming and mechanical design meet in one project. Unlike finished products it does not hide the integration problems — you see them all.

PC building tools with a bottleneck calculator that estimates CPU-to-GPU balance per game and resolution. Where PCPartPicker answers compatibility, this answers whether the balance makes sense.

Checks part compatibility and compares prices while you plan a PC build. Against a manual list it catches the mismatch in advance — an underpowered PSU or a cooler that will not clear the case.

Reviews TVs, headphones, monitors and mice through laboratory measurements, with methodology and raw data published. Unlike opinion reviews the results are measurable, and you can reweight the score for your own use.

Video surveillance software with a Turkish interface covering camera management and recording. Compared with English-language surveillance software it is practical locally for language and support.

A search engine for the specifications of consumer electronics, with comparison. Against manufacturer pages the data is normalised, so the same property written under two different names by two brands lines up.

The community archive of 3D printing models, mostly Creative Commons licensed and shared with print settings. Against Printables and MakerWorld it is among the oldest and largest — still the first place to look for a niche part.

Simulates Arduino, ESP32 and STM32 in the browser, with virtual sensors and displays attached. Against real hardware you start without waiting for a board — the logic gets verified before anything is soldered.
