Bringing back the Store

We’ve had too many requests to ignore. We’re bringing back the store here to our home website. Everything will still be available at eBay, but prices here will be a bit lower as we’re not having to pay all the extra listing fees.

Also, we will soon be adding an investment page to track and discuss investment opportunities that we actively invest in. Many of these are publicly traded companies. Just always do your own homework.

Will Prowse Gives Our BMS a Real Workout!

The eBay sales went nuts, followed by silence as my entire inventory of 4S 12V 60Amp LiFePO4 BMS units turned in a matter of minutes.

Then I received an email from a friend and customer providing me with a link to the video….

All I can say is Wow! I have never seen such an intellectual and fantastically exciting examination of anything within the realm of electrical circuits.

We’ve posted this on our Projects tab for long-term storage, but this was so fun to be a part of, we’re posting it here. Take a look:

Will Prowse is amazing. I am so impressed with this young man! William, I’d like to buy stock in you right now!

Busy Bees

We’ve been under an almost overwhelming volume of activity the last month, and it has caused us to retrench a bit from our daily upkeep of the website.

First, we’ve killed our storefront here at Gridvision.net. All sales are going through our eBay and Amazon channel at this point. Dueling inventory code was just not something we have time to write at present. We’ve entered the Global Shipping program of eBay, and we’ve already begun making sales around the globe. Our most active non-continental US areas are Australia, Italy and Puerto Rico. Hawaii has been strong as well. We’ve also entered into a deal with a large US supplier of lithium-based cells, and we’re about to begin offering these at excellent prices through our eBay channel. This will complement our existing manufacturer relationships, and allow us to offer an entire array of chemistries and sizes.

We’ve teamed up to start a new entity that has just now been awarded a Patent Pending on a production process for Graphene Nanoribbons. We are actively looking for a suitable lab environment and partner to prove and refine the manufacturing process. Our new entity is General Graphene Technology, Inc.

Over and Out.

UV-C Sterilization Project

Antibiotic-resistant microbes are increasing in strength and in number. The rates of change themselves are also increasing. Society should be worried.

We began researching ultraviolet sterilization methods, and after settling on a wavelength of about 280nm, we had a lab design and produce a prototype array for us. (We have a few extra arrays if you are feeling experimental.)

The business end of our UV-C LED array.

Our array is driven by 20-28 volts DC, and requires a constant current of 125mA. At the moment, we are driving the array with our favorite DC power supply, but we intend to design a dedicated constant-current LED driver to integrate into the next iteration.

Covering the array with a box, and zapping food, toothbrushes, and anything else not bolted down.

UV-C encompasses wavelengths that tend to be almost completely absorbed by our atmosphere, and that’s a good thing as UV-C can cause cancer, blindness, and other major health issues. It also happens to be perfect for killing microbes.

As we became interested in the technology, we began seeing plenty of small devices for sterilizing small tools such as nail salon equipment. Don’t buy any type of UV-C equipment that you can see into the sterilization chamber. Such devices can hurt you, and are ripe for eventual lawsuits. Our next iteration will include a kill-switch that shuts down the device if it isn’t properly closed (similar to how a microwave oven shuts off if you arbitrarily open the door while it is running).

We are seeing a lot of patent applications in the field, and I expect the area to grow tremendously. We’re going to mount one to a Roomba and let it continuously zap our floors once we finish building a protective/restrictive cover for it….


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 https://code.nsa.gov/. 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.

“Gas, Gas, Gas”

You veterans out there know those three words well, and I know you’ll never forget your date with the gas chamber back in basic. Ah, the memories….

We build equipment for international journalists, and we were recently asked about protection from CS Gas (“riot gas”). Note that CS attacks anything wet on the body such as eyes, nose, and mouth.)

There’s a lot of misinformation out there regarding gas masks, respirators, and all the various filter cartridges. The CDC/NIOSH and OSHA are the place to get correct info, and below is a summary of what you will find there.

CS Gas is considered an “organic vapor.” Suitable respirator cartridges should be mated to a particulate filter of at least N95 grade. Filter ratings are N: not resistant to oil, R: resistant to oil, and P: oil-Proof. P is the best rating.

Suitable cartridges for CS Gas include the following:

  • 6001 Organic Vapor -Black
  • 6003 Organic Vapor / Acid Gas – Yellow
  • 6005 Formaldehyde / Organic Vapor – Olive/Black
  • 6006 Multi-vapor – Olive

Filters and cartridges can expire even without use, and they should be replaced regularly. Store cartridges in their sealed plastic packaging until needed.

We recommend an appropriate gas cartridge paired up with a replaceable particulate filter. Proper fit of headgear is also important. Whiskers or beards will prevent a proper seal/fit.

Just because you have a mask/respirator does NOT mean you are safe from harmful vapors. Move and communicate. Don’t stick around unless you understand and accept the consequences.
