Solar & DC Circuit Breakers

We’ve received a new shipment of Solar/DC circuit breakers. These are DIN Rail mounted MCB (mini-circuit breakers). Check them out in the engineering shop here: Solar & DC Circuit Breakers

We have these in three trip levels:

  • 16Amp
  • 40Amp
  • 50Amp

Plus we ship them with sections of DIN rail.

A Few Good Links

The NSA open-source code project is fascinating whether you are a code writer or not. Check it out We will post the link in our project area for permanent access.

Another treasure is a research paper by Professor Jem Bendell. The paper may be downloaded directly from our site here: “Deep Adaptation: A Map for Navigating Climate Tragedy“. Professor Bendell’s website is here.

Are you a Youtube Video Creator?

And do you enjoy working with electronics and lithium batteries?

If so, we’d like to talk to you about a partnership with us. We have a ton of projects and tutorials we’d like to create, but we just don’t have the expertise. And that’s where you come in.

Use our contact form to get in touch. You might be exactly who we are looking for.

Update to Our Security Toolkit

We’ve made an update to an existing project by adding a new spam/user registration plugin to our toolkit.

Read about Bryan Hadaway’s “Stop Spammers” plugin for Word Press, and get it running within minutes on your Word Press site if you don’t already have it installed. We’ve been impressed with its capabilities.

LIM – The Linux Industrial Machine®

We’ve just listed our first industrial computer in the Engineering Shop. Check it out here.

LIM is a small-form-factor powerhouse of a computer. Totally quiet. No moving parts, so mount it in any geometry. If you don’t have Linux desktop in your life, you’re about to. Check it out, and let us know what you think.

Industrial Space and Hack Prevention

A lot going on here at Grid Vision.  We’ve rented industrial space to warehouse our growing inventory, and to expand our battery-building activity.

We’ve also gone through a series of website security upgrades.  Every web admin should look at what the folks at Nginx and ModSecurity have put together, and use the combined tools to tighten up.  We’re averaging about 75 login attempts per hour into our systems, with an occasional “advanced” attempt to crack things.

We’ve been busy with admin and plumbing tasks, but we will be getting into writing up a few projects for everyone to follow soon.

We will soon be offering NEW 18650 Li-ion and 26650 LiFePO4 cells here in our store. 

Global Trade

In grad school I took a few courses dealing with global trade, the World Trade Organization, and other, at the time, mundane topics.

Today, as I work with a customs broker to complete an import form required by US Customs, I find myself reading the Official Harmonized Tariff Schedule of the United States International Trade Commission to identify the exact codes I need to determine the tariffs I will be required to pay, while also learning about various satellite tracking options I have to watch my shipments move across the seas.

It’s actually quite fascinating to jump into the global trade business, and move from rote classroom theory into real-world, hands-on applications.  In some nostalgic way, I sense the excitement early traders must have felt as they navigated all the obstacles and opportunities associated with global trade.


What We’ve Been Up To

For those of you interested in our adventure, here’s a condensed update:

  • We opened a store on Ebay, and we’ve been so busy designing product ads, making sales, shipping packages, and reordering product that we almost haven’t had time to do anything else.  The Ebay selling platform is actually quite amazing, and we’ve really had our hands full keeping up.
  • We’ve negotiated pricing with several overseas vendors on a handful of different products.  This has led us to learn about genuine “shipping,” and we’re expecting to visit the port in Tampa soon when our SHIP-ment arrives.  I think we’re gonna need a bigger truck soon.
  • We’ve negotiated a bulk purchase agreement with a major solar panel manufacturer whereby we buy up front in bulk, and the manufacturer ships directly to our customers to help minimize shipping costs for everyone in the chain.
  • We’re seeking industrial space in the St Petersburg, FL area.

That’s it for now.  Gotta run.  We are continuing to fill out our product offerings, and we’ll be photographing/documenting several helpful projects in the next few weeks.
