Humm. How crazy did you want to get? A Rubens Tube is really cool. It allows you to see standing waves. Its a physic concept. Easy to make. Some PVC and fittings. You can play a song and see it 'dance' towards the bonfire. Might not be a practical way to light the bonfire but it would be an awesome effect.
One of many example of 'how to build'

Spinning HD? That's about the lifespan of a traditional hard drive regardless of OS.
im a fan of m.2 sata SSD. Plugs directly into the PCI-e slot and is significantly faster then SATA SSD. I ran two in RAID-0 on my MSI laptop. When working with large CAD files or video, the improvement is dramatic. Fast file transfer.
had a workstation GPU in the laptop also, video editing and modeling in realistic mode was not a problem.
MAC can do all this, but you have to buy it that way, often can't upgrade, and $pend 3x as much.
Im not hating on you WigWag, just Apple ?

I think Jimbo is right. $5 or 3 for $12, 6 for $20. The goal is to sell tickets. $10 a ticket would price me out, offering better odds for more money, ex: 6 for $20; encourages people to donate more.
its physiological. I would feel good paying $20 for 6 or $12 for 3 but I wouldn't be able to justify $10 per ticket.

Today was fun. I set up a 3D scanner. It's a cool unit. Runs about $800. Good resolution for the price.
I wanted to scan something interesting so I ran across campus and grabbed a platypus skull from my wife's lab. It turned out really cool. Imports easily into SolidWorks.
ill scan some tool related stuff soon.

If you're near Southern California I can fix it for you. No charge but you buy parts.
I'm not a fan of Mac, I consider myself to be an authority on computers. Afterall my field is advanced computers and electronics. ?
I have heard all the 'reasons' people buy a Mac but in the end it's really just clever marketing.
Bit for bit a PC is a better value with more capabilities. As far as build quality, you can find a PC that is built better then a Mac for 1/2 the price. The thing that frustrates people; there are 40 different PC vendors who each make 20 different models.
with Mac there is one vendor who makes three models. Comparing Mac to PC is hardly ever an apples to apples comparison.
for $800 you can get a PC that has 16gb ram, 1tb hdd, i7 quad processer, 4gb GPU. The same configuration in Mac is going to be $2k.
Sorry, I don't mean to be a hater, I really dislike how Apple runs 'marketing'

I would either cut the pole and sand it flush, or if you want to keep both:
As other members already said,. Drill a few small relief holes around the pole. Should be easy to remove the pole. Then clamp some wood to the table and use a hole saw to make the umbrella hole just a little bigger- this will clean up the small relief holes too. You can leave it alone or plug the hole.

My mother-in-law requested tacos so I made chicken & steak, homemade guacamole & salsa, rice beans and some other assorted goodies.
Really good stuff. Everyone enjoyed the food and lots of leftover
thats my mother-in-law and her oldest son.

It is out of my pocket, I don't get any deals from them. We do have a local store that I visit twice a month, and they offered me a discount, but I refused
Your very kind WigWag. The world needs more jerky ?

I hope you are getting that jerky compensated from the vendor? Are the jerky giveaway's out of pocket?

No need to buy servos, although if you have the cash they are the best, steppers will work just fine.
gecko 540 controller with NEMA 23 steppers. Configured in micro-step mode, these things will be really fast. Pair the kit with some quality shielded wire, eliminate noise (electronic interference, not audible) Also a good power supply is key. You want nice clean power.
The nice thing about a plasma cutter, like a laser, there is no mechanical resistance with the work so the machine doesn't have to be as rigid as a CNC milling steel.
I would recommend using extruded aluminum reinforced with steel. It's lightweight and easy to work with. Your main obstacle will be keeping the Z-axis light. The heavier the gantry, the slower it is. Also takes more to get moving & stopped.

You wouldn't want to use chain, although I have seen it doen. Chain stretches too much. Belts are the way to go if speed is desired. The wider the belt the better. But if the axis is long, ~60" belts might not work. Just depends on the design.
Threaded-rod is used on DIY builds but it's not accurate. Lots of backlash. ACME rod, ball screws, or rack & pinion is more common, but more $$$.
ACME rod isn't too bad but ball screws & racks are $$$. It's what the pros use. eBay has deals though. Belts can be used but when milling hard wood or aluminum, feeds and speeds are a big deal.
Take a look at the Shapeoko 3 for an example of a low cost, belt drive CNC.
Besides backlash & rigidity, the electronics make a big impact on accuracy. This is also an area people tend to cheap out, ... at first.

I had my heart set on building a CNC router. I did my homework and narrowed the list down to three possible choices. If you're considering a CNC build, these three are solid:
Brian Oltrogge Grunblau Platform
I even considered a Chinese 6040 and upgrading the electronics.
Unfortunately though my wife has baby fever. Her biological clock is ticking and we have been unsuccessful in our many attempts.
Went to the baby making Doctor today. $400 conversation turned into $1200 'peek under the hood'.
Although we have great insurance, these fertility visits aren't covered. So it looks like no CNC build in my near future.
Damn invisible baby is already a pain in my ass.

Yesterday we invited Irvine Valley College Robotics Team to present their 'Rescue Robot' IVC Robotics won 1st place last weekend @ a University level Robotics competition.
The robot is an first responder bot that can automatically search for a victim (simulated by an orange bucket) and report back the victims location.
This is is the 2nd year the robot program has been in existence and it gets better each go!
In in about a month the team will compete in simulated rescue competition

Yes they have. The UN just had a meeting talking about Robots on the Battlefield. Many think it's inhuman for a robot to kill a person because the robot doesn't have any emotional consequences.

Another quick robot update. Meet Baxter. He is our latest & greatest 'toy'. Baxter is made by a company called Rethink Robotics. Marketed as an easy to use automation bot, Baxter can be programmed by simply moving his arms. Here is a short video of the first run. I'm just calibrating his arms but next week I'll program him to do something cool.

Milwaukee Saw Blade Sharper.
or maybe a new concept for a modular workbench. Save space by switching out the tool module

Im actually going to take it apart and configure it to write on a white-board. I have some Kreg T-Track i'm going to use to make an adjustable mount. Something I can take into the classroom and throw up on the board, press a button and away it goes.
Butt I'll draw a TIA Logo with the arm first.
Today I made a few circuit boards with my friends CNC Mill. I really need a CNC of my own but they are just so damn $$$. I keep hoping Dan will give his away.
Check out the youtub video I took of the mill in action. This PCB is a shield that attaches to the Arduino Mega board. A few sensors plug into it and turns the Arduino Mega into a flight-control for quad-copters. Nice relaxing music too.

Just updating with a new robot build. This one is called the mDrawBot. It's a kit that can be configured into 4 different XY Plotters.
mScara (current configuration) is a robotic arm plotter. Originally designed to clamp onto the edge of a desk. I mounted it to some MDF, finally discovered what MDF was good for.
mSpider: Can draw on horizontal surfaces like a whiteboard. I am going to build this unit next
mEggBot: is great for Decorating Easter Eggs
.
mCarBot: Maybe useful for making custom parking spot decals.
I will need to do a TIA Print, but for now here are a few I did.
The print resolution and quality isn't the best but its pretty cool. I need to work on my video editing skills.

We can do better then a flamethrower ? But yes, I actually learned to build a flamethrower from this Russia guy I worked with.
I uploaded my first YouTube video. Nothing special, just shows the Humanoid doing some moves, including a headstand.
My dog Alley makes an appearance. She doesn't trust technology.
