5Vpld

2026-09-10T20:53:20Z

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.

https://github.com/peterzieba/5Vpld

Flipper Zero Tutorials

2026-09-10T20:53:20Z

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.

https://github.com/jamisonderek/flipper-zero-tutorials

ISA

2026-08-26T20:53:20Z

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.

https://www.isa.org/certification

Digi-Key

2026-08-21T20:53:20Z

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.

https://www.digikey.com/

EveryCircuit

2026-08-21T20:53:20Z

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.

https://everycircuit.com/

FPGA4Fun

2026-08-21T20:53:20Z

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.

https://www.fpga4fun.com/

FreeCAD

2026-08-21T20:53:20Z

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.

https://www.freecad.org/

KiCad

2026-08-21T20:53:20Z

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.

https://www.kicad.org/

Octopart

2026-08-21T20:53:20Z

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.

https://octopart.com/

Open Circuits

2026-08-21T20:53:20Z

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.

https://www.opencircuitsbook.com/

PC-Builds

2026-08-21T20:53:20Z

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.

https://pc-builds.com/

PCPartPicker

2026-08-21T20:53:20Z

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.

https://pcpartpicker.com/list/

RTINGS

2026-08-21T20:53:20Z

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.

https://www.rtings.com/

TechSpecs

2026-08-21T20:53:20Z

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.

https://techspecs.io/

Thingiverse

2026-08-21T20:53:20Z

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.

https://www.thingiverse.com/

Wokwi

2026-08-21T20:53:20Z

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.

https://wokwi.com/

Onshape

2026-08-19T16:15:25Z

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.

https://www.onshape.com/en/

McMaster-Carr

2026-08-19T16:15:13Z

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.

https://www.mcmaster.com/

Eclipse Ditto

2026-08-17T19:47:15Z

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.

https://eclipse.dev/ditto/

SmartVision

2026-08-16T07:54:38Z

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.

https://tr.smartvision.dev/

Anyka Kamera Firmware

2026-08-12T20:51:31Z

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

https://github.com/MuhammedKalkan/Anyka-Camera-Firmware

AK3918 Kamera Notları

2026-08-12T20:51:23Z

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.

https://github.com/OpenIPC/firmware/issues/1970

OpenIPC

2026-08-12T20:51:19Z

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.

https://openipc.org/

OpenIPC Firmware

2026-08-12T20:51:11Z

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.

https://github.com/OpenIPC/firmware

OpenIPC Coupler

2026-08-12T20:51:08Z

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.

https://github.com/openipc/coupler/

OpenIPC Kurulum

2026-08-12T20:51:02Z

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

https://github.com/OpenIPC/wiki/blob/master/en/installation.md

Advantech Edge AI SDK

2026-08-05T22:16:36Z

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.

https://campaign.advantech.online/en/edgeaisdk/index.html

AvaotaF1 İncelemesi

2026-08-05T16:03:23Z

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.

https://www.electronics-lab.com/avaotaf1-development-board-offers-allwinner-v821-soc-64mb-ram-mipi-camera-spi-display-and-wi-fi-in-coin-size-form/

AvaotaF1

2026-08-05T16:03:09Z

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.

https://github.com/AvaotaSBC/AvaotaF1

LiteEMF

2026-08-05T16:01:43Z

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.

https://github.com/LiteEMF

Kontrol Sistemleri Uygulamada

2026-07-29T07:51:41Z

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.

https://www.youtube.com/playlist?list=PLn8PRpmsu08pFBqgd_6Bi7msgkWFKL33b

Kontrol Sistemleri Dersleri

2026-07-29T07:51:08Z
