When designing Bluetooth PCBs (e.g., JieLi AC695N/AC696N), pay attention to DC-DC layout:
• Prioritize short, wide ground paths – avoid long thin traces.
• Place decoupling caps near chip pins.
• Keep DCDC away from antenna, near battery.
• Inductor close to SW pin, no vias, no components underneath (especially MIC).
• FB sampling after output cap; divider resistors near FB pin.

519: The Password Is All Zeros — Embedded

Mark Omo and James Rowley spoke with us about safecracking, security, and the ethics of doing a bad job. Mark and James gave an excellent talk on the development of their safecracking tools at DEF CON 33: Cash, Drugs, and Guns: Why Your Safes Aren't Safe . It included a section of interaction invo

A Controversial Takeaway: So, before you launch your next expansion phase, ask yourself: Are you trying to build a resilient energy network or a fragile culture of participation trophies? The most expensive thing in a hardware partnership isn't a broken part; it's the silence that comes when you're too scared to say it's broken.

Memory is running out, and so are excuses for software bloat

Opinion: Maybe the answer to soaring RAM prices is to use less of it
