Welcome to Teardowns & deep dives
Some of us cannot own a gadget without wondering what is inside it. This board is for that curiosity: opening up handhelds, consoles, chargers, power banks, routers, old phones and mystery boxes, then explaining what you found. Identify the chips, trace the power path, compare revisions and work out why the designers made the choices they did.
What belongs here
• Photo teardowns with notes on chips, connectors and build quality
• Deep dives into how a device works, from its power circuitry to its display interface
• Comparing hardware revisions of the same console or handheld
• Identifying unknown components and asking what a part does
• Write-ups on old-but-salvageable tech and what is worth saving from it
What goes elsewhere
• Fixing what you found broken: Soldering & repairs
• Dumping and analysing firmware: Firmware & reverse engineering
• Installing mods: Console modding
• Security research on what you opened: Security & ethical hacking
• Router internals as a networking topic: Routers & networking
• Gadgets like the Flipper Zero in use rather than in pieces: Flipper Zero & hacking gadgets
Making a good teardown thread
1. Say what the device is, with its model number and revision if you know it
2. Photograph each stage in good light, with the board in focus
3. Label chips with their markings and say what you think they do
4. Note how it went back together, or did not, and any traps such as hidden clips or glue
5. Credit anyone whose teardown or notes helped you
Opening things safely
• Unplug it first, and disconnect the battery as early as you can.
• Glued-in lithium batteries: soften the adhesive with gentle heat or a little isopropyl alcohol and use plastic tools. Never pry with metal against a pouch cell, never puncture or bend it, and retire any cell that is swollen. Have a non-flammable surface ready to set a damaged cell on.
• Capacitors can hold a charge. Camera flashes, microwave ovens, CRT televisions and monitors and mains power supplies can give a dangerous or lethal shock even when unplugged. If you do not know how to make them safe, leave them closed. Microwave ovens and CRTs are not beginner teardowns.
• Wear eye protection when prying, cutting or snapping clips.
• Mind ESD on exposed boards.
• Some older devices contain parts that need extra care, such as mercury in old switches and cold cathode backlights. Dispose of them properly rather than in the household bin.
Board rules
• Your own hardware, legal and ethical only.
• Do not post leaked confidential documents, copyrighted firmware, BIOS or game files, or anything else piracy-friendly.
• No malware, and no selling or paid services. Teardowns are for learning and sharing.
• Safety warnings are part of the rules here. If a post skips an obvious danger, someone will add it, and that is a good thing.
The house rules still apply: be kind, write in English (other languages get translated automatically), no spam, no keyboard mashing and no self-promotion spam. Spot something off? Use Report. This thread is locked, so if you have a question, start a new thread.
