Someone on facebook is selling these:Fantastic, if you want set your home on fire. This is wrong on so many levels. It basically goes against all good practises where it comes to building Li-ion battery packs. The fuses will not help against the number one issue: when a Li-ion cells goes off, the thermal runaway will ignite the surrounding cells.
I attempted to let the seller know this is a dangerous build, but they don't seem to care.
I thought it would be worth while getting opinions (technical and rational) from the community so they can see that it's not just me being annoying.
What are your thoughts on using random batteries that are soldered together in this way?
Rigol can go to 100MHz (or 125MHz) but is severely limited by its sampling rate.Incorrect.
Links to the tools please.
The board holder does look very nice, and do I see you invested in a chip tester? The one Adrian Black (digital basement) used to test al kinds of chips with?
I really like the board holder. If a board is too long, you can always hold it sideways or buy an Aluminum bar at a metals supplier.
Yes, I am assembling the retrochip tester from 8bit-museum.de. I found it is much cheaper (but more painful) to order the parts from DigiKey; $120 vs about $250.

I have to find the ProsKit desolder gun. But it was about $100; bought it as a "first timer" on another account. (Yes, I am that cheap!)
It is not an auxiliary coil that is used for deriving 5V for volt amp meter.
From the main transformer after full wave rectification, I have used it.
I want to derive variable power supply up to 30V and current limiting adjustable up to 5 amp.
