xTool F1 Review – First Impressions

xTool F1

xTool F1

My friends at xTool have provided me with one of their latest offerings to review, the xTool F1.  The F1 is a highly portable laser engraver which contains 2 separate lasers in one housing.  One laser is a 10 watt, 455 nanometer (nm) wavelength laser and the second is a 2 watt IR, 1064 nm laser for marking metals.

The laser is a galvo system and an explanation of that type of laser can be found here.  I’m told the author of that article is pretty awesome!

Because the galvo laser uses a mirror system instead of mechanical movements across an X and Y axis, it typically is a LOT faster than a conventional desktop diode laser.

Conversely, the tradeoff here is that the range of the mirroring system results in a considerably smaller useable area.  Also if cutting an item,  the edges may have a slight bevel to them. This is due of the angle of the laser cutting beam.

Where the F1 really shines brightly is its ability to mark small items quickly.   Items such as jewelry, coasters, leather patches, and tumblers (with optional rotary) can be rapidly produced.  Because of the portability of the F1 it is ideal for Craft Show and Flea Market sales.   Customers may walk away if you tell them their tumbler will be ready for pickup in 30 minutes.  However, if you tell them you can produce it in a minute or two right in front of their eyes, they are more inclined to stick around.   Time is money, as they say.

Ooni Pizza Oven Update

Ooni Pizza Oven Update

Just over a month ago I bought an Ooni Pizza Oven, the Karu 12 Multi-Fuel.  It was an impulse buy.  But suffice to say I’ve eaten more than a few pizzas and calzones in the last month or so.  I’ve been having so much fun with this thing but I want to share a few things I have learned along the way to any potential buyer of the Ooni.   If you are a fence sitter and thinking about buying one I’d absolutely encourage you to do that.  But there is a learning curve.

Buying an expensive stove, oven, stand mixer or any other kitchen porn won’t make you a good cook.  Using your equipment a lot with study and experimentation will.  There is so much to learn regarding a brick pizza oven like the Ooni.  There are hundreds of posts on the Facebook forum alone regarding dough hydration.

Justway Manufacturing Services Review

Justway Manufacturing Services Review

unknown.png

I’m a MAKER.  They used to call us nerds, and then geeks.  I personally own a CNC machine, four 3D printers, 5 lasers, a vinyl sign machine and some of the best tools money can buy.  Before I go to the store or head to the internet to buy something I stop and ask myself, “Can I make this myself”.  A lot of times I can.  Even sometimes when I can it isn’t practical for me to do so or I find that I can’t make it out of a preferred material.  Or I have reached the limits of my machines. This is where Justway comes in.

Justway is a manufacturing service that can make ALMOST ANYTHING.  They specialize in:

  • CNC Machining and Milling
  • Sheet Metal Fabrication
  • 3D Printing
  • Injection Molding
  • Urethane Casting

Their services are ideal for almost anyone.  And their services really excel in a few different areas.  If you dreamed up a great idea and you needed to build a prototype but have no manufacturing ability then Justway is a perfect choice for you.

NIIMBOT Label Maker D110 Review

NIIMBOT Label Maker

NIIMBOT D110

The folks at NIIMBOT have made yet another great label maker.  I have previously reviewed their B21 Label Maker, and their B3S Label Maker.  Both are stylish and fun and very efficient.  And while both are portable the NIIMBOT Label Maker D110 really excels at portability.

It checks in at 4.2″ tall, 2.9″ long, and 1.2″ wide.  And it is so light you’d never feel it after you slipped it into your backpack, purse, or toolbox.  And after posting a picture of it after I received it, my brother messaged back and said he owns this very label maker and the portability is what he loves best about it.

The design is sleek and simple with one control button, one release mechanism for changing label rolls, and one USB-C charging port.  And it is of course, a thermal printer that never needs ink.

New HTTPS Site Certificate

I thought I had upgraded my SSL certificate on John’s Tech Blog but it expired on Jun 30th.  I was able to install the new certificate on the morning of 1 July.

Don’t be alarmed if you have to accept a new certificate when visiting the site.  Nothing fishy going on.  Just me installing the new certificate incorrectly before the other one expired.

Ooni Karu 12 Review

Ooni Karu 12 Review

Ooni Karu 12

Ooni Karu 12

For a number of years I have fancied myself a bit of a good pizza chef.   Mind you, I only made pizzas for myself and family and friends but I’m getting pretty good at it.  My craft has evolved over the years.  But I have really stepped up my game with the addition of an Ooni Karu 12 Multi Fuel Pizza Oven.

I want a giant kitchen with a real brick oven but at 60 years of age I’m probably in my last home.  Over the last couple of years I’ve been eyeballing outdoor pizza ovens.  The other day I was in a local Dick’s Sporting Goods store and I saw one in a store for the first time.  They have always been sold out.

An employee came by and asked me if I was interested and I replied, “Maybe”.  His response was “We can’t keep them in the store”.  Okay, John, it appears the time to get an Ooni is now or never.   I got just the oven and I sprung for one of their pizza peels as well.  I have no beef with the pizza peel but I’m a woodworker and subsequently made my own wooden pizza peel.  Probably should have just done that from the start.

LG 43UQ7590PUB Piece Of Fucking Shit Award

LG 43UQ7590PUB Piece Of Fucking Shit Award

LG 43UQ7590PUB

I recently bought a new smart TV from  BestBuy.  The LG 43UQ7590PUB

It’s a Piece Of Fucking Shit and earns John’s Tech Blog’s coveted Piece Of Fucking Shit Award.

I bought it in January 2023 and it has been nothing but trouble.  My wife and I frequently watch TV in separate rooms and just about the time I get comfortable and engaged in some program here comes the call from the other room.

“Honey, the TV sound disappeared”, or “Honey, the TV just rebooted and now XXXX app doesn’t work”.

I’ve reached the point where mild annoyances that this TV produces has now expanded into full blown rage.   Two days ago I told my sweet wife…….“Fuck this fucking TV.  It is driving me crazy.  I’m buying a new TV”.  Normally, there might be a little back and forth discussion coming from the mouth of a reasonable and loving partner.  Option exploring.  My wife is good and real sweet in this department.

No discussion this time.  She was 100% in agreement that this TV needed replaced.  To her credit she didn’t use my US Navy vernacular sentence enhancers.

Sculpfun S9 To S30 Upgrade Kit Deeper Dive

Sculpfun S9 To S30 33 Watt Upgrade Kit

Sculpfun provided me an S9 laser and then subsequently provided me a Sculpfun S9 to S30, 33 Watt Upgrade Kit.  I did a “First Impressions” blog which you can read here.  After using it for a couple of weeks I decided to do a deeper dive on upgrade kit.

Laser Module

Sculpfun S9 To S30 Upgrade

33 Watt Module

The S30 Ultra 33 watt module is considerably larger than the original S9, 5.5 watt module and contains a lot of really cool features

Most noticeable is the addition of an all metal air assist.  One of my favorite features of the air assist is that it not only is secured in place with an allen screw, it also threads on and contains an O-ring to keep the air contained.

The tube is considerably larger than most competitors air assists which allows for a higher volume of air movement.

Removing the air nozzle allows for access to the lens for cleaning.

Sculpfun S9 Upgrade Kit 33 Watt Review

Sculpfun S9 Upgrade Kit (33 Watt) Review

Sculpfun S9 Upgrade

Sculpfun 33 Watt Laser

The great folks at Sculpfun recently sent me their S9 Laser which I did several reviews of.  Also, they very kindly sent me their 33 watt Sculpfun S9 Upgrade Kit which upgrades the kit from approximately 5.5 watts to a FULL 33 WATTS OF POWER to review.

Diode laser modules are roughly 5.5 watts and to obtain higher wattages, multiple diodes are combined into one beam.  In the case of a 33 watt module that means there are 6 individual blue diode laser modules.

There is one important point that I would like to make before I begin this review.  Let’s get to it, shall we?
