Your relay that may be able to switch load at 220V AC without a hitch, but may die rather quickly under a much lower DC load voltage.

Yes, you read that right. Relay contacts have much lower DC voltage ratings compared to AC. This is much better explained in the following infographics.

BEYOND ARDUINO

🚀 **Level up to Pro with the ATmega88P Prototyping Board!** 🚀

This prototyping board is a deployable, simple prototype controller board based on the ATmega88P microcontroller.

Ditch the abstraction layers and master your hardware with a board designed for bare-metal C/C++. Whether you're switching 7A loads with the onboard dual-channel relays (PB0/PB1) or building a professional UART/I2C sensor hub, this 12VDC-powered controller is your gateway to industrial-grade performance. 💻✨

**Key Features:**
✅ **High-Power Switching:** Dual 7A @ 250VAC Relays
✅ **Precision:** 8.000MHz External Crystal
✅ **Connectivity:** Dedicated I2C, UART, and ISP Headers
✅ **Expandable:** Built-in prototyping area with SOIC-16 and TH pads

Build faster. Build smarter. 🛠️

Classic test equipment are designed and built to last forever. They use high grade components, like the kind you will find in high-rel stuffs like Military gear where failure is not an option.

I like tinkering with these oldies, because each one is a storybook of fine engineering with a lot to tell. The way the circuit and components are meticulously laid out, wire routed, even how the screws are placed and spaced - all contributed to an unimaginable level of performance even accomplished engineers would think unattainable with the available technology of the time.

Like all things, they will eventually fail. The good news is, classic equipment uses garden variety parts that are still available in the wild. Use of custom parts is not yet widespread, no ASIC and the likes. That means, with enough patience, you can repair them.

Who would have suspected that termites would have a taste for electronics? I managed to rescue it just in time before it was completely devoured.

Crisis averted! Sakto, may pang-spot weld na ako para sa mga DIY battery packs ko.😁

My workbench.

A model of extreme disorder.
But I know exactly where to find my stuff, as long as no one else touches things around.
My New Year's resolution was actually to tidy it up a bit. It seems that can wait for another year.

Can you relate?

We installed an AI agent to work in our messenger chat box. We have no idea how it will handle the job, we'll just see if it will be helpful :-D.

Update: We temporarily shut it down because it gave inaccurate/wrong answers to some chats :-D. Probably because of very little information it has about e-Gizmo product lines as of this moment. We will try to figure out how to make it respond more accurately, and till then....
