Been a few weeks since i posted anything and was inactive. I actually visited Amsterdam. Such a beautiful place. I am thinking to start posting circuit analysis now.
Starting off my first power supply journey. A transformer, rectifier, bunch of capacitors, led and power regulator. I have to run a 12 V DC motor. This supply may have ripples at 50 Hz AC. I don’t have an oscilloscope to test yet. I designed a bad pcb though. Lots of conflicting connections. Suggest me whats wrong. Can rearranging components work better?
Planning to build an AC to DC power supply for this little BLDC fan i extracted from a refrigerator. I will start with standard transformer then I am thinking to use SMPS transformer. I have two of these.
‼️🚨 UPDATE: The TanStack npm attack is now a full campaign.
'Mini' Shai-Hulud has hit:
- OpenSearch
- Mistral AI
- Guardrails AI
-UiPath
- Squawk packages across npm and PyPI
The malware specifically targets AI developer tooling. It hooks into Claude Code (.claude/settings.json) and VS Code (.vscode/tasks.json) to re-execute on every tool event, long after the infected package is gone. npm uninstall does not fix this.
Since the time I started posting, I only posted about things that I am learning and building in electronics. I also love coffee. Here is the latte art I made today.
