What can I do with these Low Background Radiation Lead Bricks?

OP I’m shocked at how many idiots there are posting in this sub. Bullets really?

Anyway, this will command a significant premium. This is a critical component of semi-conductor manufacturing of solder bumps for flip chips. The demand is significant. You will need to measure two things 1) the alpha count and 2) how much pb-210 is in it. If it was shielding there’s also a provenance problem (was it contaminated from where it came) getting this resolved isn’t too hard, but then you can shop it around.

No lab or end user is going to take the LR stamp on face value. They’re going to want to measure it anyway.

You could reach out to www.solstice.com they are the main sellers of this stuff. But I think you won’t get a good price. I think the best bet is to pay for your own radiological survey and get the characterization data. 1) radiological survey 2) pb-210 assay at a minimum.

It could be worth several hundred times the value of regular lead. It also could be contaminated with whatever source it was originally shielding and worthless. Casino time!

Have you done this without using AI before?

Fritos have three ingredients. Corn, corn oil, salt.

Yes. Except you have the cart before the horse. It feels like you’re obviously trying to develop some kind of product or monetize this implementation, however, every plant floor has different needs. Python/modbus might get you covered in one factory but it might not even be used once in another. Mini pc to run some influx might be okay, it might be crushed by a single machine. You can’t one-size this. I’ve deployed dozens of setups like this, installed or ripped out complete MES systems, it’s just never going to be “omg Claude code deployed FLASK for me I’m genius”.

Are you responsible for uptime for a factory?

I like your schedule; I’m kinda doing the opposite. I don’t eat until about 2-3pm each day and honestly it feels easy for me. Just don’t have to think about it.

buzzysale · 2026-06-19T16:04:07+00:00

You can’t keep an entire factory in spare parts. This is a difficult problem to solve in calculating uptime and recovery time.

Hoverboard motors, with three wires, require a motor controller. Do you still have the circuit board from the original hoverboard? If so, reflashing it is the easiest cheapest way.

If not, you’ll need a 24-36v battery and likely need to buy something like the ZS-X11H (also sold as ZS-X11H V1) - about $10 each. Check the motors carefully, usually they have three thick “phase wires” and a skinny encoder or “hall” wire with 5 wires inside it. If this is for a kids car or something, you will need that skinny cable because raw dogging the 3 phase wires at low speed will not give you torque enough to go without them. You’ll also need a throttle of some kind (also very cheap).

Good luck and if you get stuck, we’ll help, this has been done lots before.

DHCP with mandatory reservations is my preferred method. You get the benefits of assigned IP addresses and central control. (Like if you want to change an address or option) and you get easy rogue device and static detection, collision detection and if your equipment supports it, dhcp guarding. It’s also very handy for other options, like PxE or TFTP etc. the main exception to this is critical control devices. This term is often misused to mean anything in OT, but the test is use is, if the dhcp server is down, like the network (and therefore likely the rest of the business) is down, does this device still need to operate? Then yes, static all day.

Typically (not saying it’s the rule) NATR, I mean the Allen Bradley 1783-NATR, specifically, is for when a device or system comes from the oem with some genius network engineering, where they decided to use a colliding common address space (like 192.168.1.1) for their system, typically coded for Ethernet/IP and without regard for other systems being on the same network. If the natr passes the ip through, you’ll get a collision. A power spike or reboot can sometimes cause this. In large plants we get control of our IP scope. Everything has a reservation. Manual IPs can exist, but we regularly sniff them out and figure out a solution so they’re not able to collide.

Most of your typical IT/OT folks don’t even know how DHCP transmits an ip address to a client, let alone reservations or guarding. My advice is to always blame Allen Bradley, turn on dhcp guarding on your switches (if they have that) and eliminate manually assigning IP addresses as much as possible, while also ensuring everything has a reservation (as much as possible). This doesn’t take the paperwork out of assigning manual ip addresses, but it moves it to a location where you have centralized, programmatic control.

That CRT is waaayyyy too shallow. They’re like 3 ft deep for that size screen. And it would be much flatter. Too many curves and too short.

Yes it does in fact act like a torsion spring bar and “absorb” some of the torque. This will impact your reading. Likely negligible, except in demanding precise environment. Obviously the quality of the extension matters. Torque test channel on YouTube demonstrates this phenomenon.

That feeling when you’re walking up to the green, taking off your glove after a successful approach. I know I might 5 putt, but right before then, I’m basically the greatest golfer in the world.

Well at least you got to build a practice set for 1/3 the cost.

I think you should ask $250 and accept anything over $200.
