Last Strike?

Thought I found all the lightning damage. Not so… 

I knew the power supply for the older Cetus 3D printer was burned out. Zero voltage output. I needed a new power supply to test the printer. I have two Cetus 3D printers as shown in the pictures, but their power supplies are very different.

The newer printer on the left has a much higher wattage supply than the one that has failed on the right and a different plug. I had to order a new power supply for the right-hand printer as it was definitely dead, with zero output.

The replacement power supply came today all […] Continue reading » Last Strike?

Big BOOM – II

This week started with a literal BANG!

Lightning again struck my house here in Frisco, Texas. This is the second time. First time was Monday June 29, 2009. A little over 11 years ago. Search “lightning” (upper right corner) on this blog for more information. (Yes, this blog is much older than ten years.)

This one was on Sunday morning August 30, 2020. About O500.  One hell of a wakeup for a Sunday morning. (Words carefully chosen…)

The bolt struck my nearly 20 year in-place vertical amateur radio antenna. Just outside the bedroom window. The vertical antenna is mounted above the lowest corner of the roofline on […] Continue reading » Big BOOM – II

Giant Suck

Raw Sewage

I have abandoned Facebook for (I think) the third time.

FB has some good points and I enjoy keeping in touch with “real” friends and family. I do not judge my self-worth by how many long-lost and stray-cat “friends” want to join me.  My real friends know how to otherwise keep contact with me if they desire.

The political climate and vicious personal  attacks have driven me away again. The fraudulent advertising is also no attraction. There is more raw sewage in Facebook than I can withstand. I don’t desire the exposure when it is so easy (and hard) to just turn it off. 

It […] Continue reading » Giant Suck

Creative Manufacturing Art and My Personal Philosophy Best of Both

I have one outstanding way of creating wax masters for lost wax casting. I use a high-speed spindle (up to 25,000 RPM) on a Taig Micro Mill. If I can draw it properly, I can machine it in 3D.

The limitation is the 4-axis ability of this machine. That doesn’t sound like much of a limitation to most machinist. 4 axis means X, Y, Z movement with an additional rotary A axis. There is a huge amount of work that can be accomplished with 4 axis milling.

But there are some designs that can benefit from additional movement freedom. […] Continue reading » Ramblin’ On

Internet Outage

We experienced a two (plus) hour outage of our internet yesterday. Almost all our external communication is delivered by that system. The cable television, home phone line and of course our Internet data feeds are dependent on that connection. Its importance is second only to our electrical power feed. Our home is 100 percent electrical energy dependent.

The immediate effect was how quite everything in the house had become. The power was on but only the cell phones would communicate. The air conditioning was performing normal. The indoor temperature was still perfect. All our other electronic “toys” had become almost useless without their normal data feeds.

I liked the […] Continue reading » Internet Outage
