Mailing List discussions

Policy decisions surrounding HPR are taken by the community as a whole. This discussion takes place on the Mail List which is open to all HPR listeners and contributors. The discussions are open and available on the HPR server under Mailman.

The threaded discussions this month can be found here:

Server move

We are currently in the process of moving the HPR server. A server has been set up on Amazon AWS, and we are currently setting up a copy of the database, mail system and Mailman mailing list service. The Gitea Git repository has already been moved and is in use. The static site created by rho`n is being set up to provide the main HPR website. Work is being done to provide the interactive facilities that need the database, such as show and comment submission.

Contacting old hosts

The rate of show submission is unusually low this year. The number of active contributors is low too, with a small group of hosts keeping the HPR project from sinking below the waves.

A question for the HPR Community - can we contact old hosts to ask them to contribute again?

Conversion of Windows-1252 characters to UTF-8 Unicode

As mentioned on the last Community News the Windows-1252 characters (aka Latin1) in the database were converted to the UTF-8 Unicode format apparently without exceptions. If anyone finds any unexpected characters in episode titles, summaries, tags or notes from now onwards please let us know and we'll fix them too!

Hi Retro;

Spot welding looks like an excellent way to connect new cells, I remember one video where someone used a couple of car batteries and a momentary switch and got really nice results.

However as these are already used cells, they will fail more quickly. I've had to replace a cell three times recently from the 20 cell battery that I've been using about a year.

The spot welding is harder to take apart, they come that way in factory made batteries and you have to pull or cut them off, which usually leaves some metal still attached. For this reason it is better to use solder for older cells in my opinion.

As for safety, I am tempted to clamp my solder iron to a cell and leave it on maximum heat for 5 minutes to see what happens, probably nothing spectacular. I only heat for about 10 seconds or so max because I don't want to damage it's capacity. The metal of the cell itself acts as kind of a heat sink so it doesn't get as hot as a small component would, and soldering irons are built to melt solder. I've done over 100 solders on to bare cells without mishap or loss in capacity.

The main danger is cutting yourself while taking apart a battery pack, the conductor strips are thin and very sharp when you cut them. Other hazards are shorting stuff out with your metal cutter and seeing bright sparks. I once punctured one of the flat cells by accident and it started to get hot and smoke and smelled awful, but I can't see that happening with 18650s.
