How Can I Make a Simple Rectifier?

Click For Summary

Discussion Overview

The discussion revolves around how to create a simple rectifier, including requests for guidance and resources. Participants explore various aspects of rectifiers, including historical references and materials used in construction.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests information on building a simple rectifier and asks for a graph.
  • Another participant suggests searching online for tutorials on rectifiers, indicating a wealth of resources available.
  • A participant speculates on the difficulty of obtaining doped silicon for a pn junction and mentions an alternative of using germanium, while also referencing a homemade tube diode.
  • Participants share links to historical selenium rectifiers and discuss their packaging and historical context.
  • There is a nostalgic reflection on the past practices of replacing electronic components, including tubes, in local stores.
  • One participant expresses curiosity about the customers who used selenium rectifiers, leading to a discussion about the commonality of replacing parts in older electronics.
  • A later reply checks in on the original poster's progress with the rectifier project, suggesting a link to a mineral resource.
  • The original poster expresses gratitude for the help received and indicates plans to proceed with the project.

Areas of Agreement / Disagreement

Participants share various viewpoints and resources, but there is no consensus on the specific methods for constructing a rectifier or the materials to use. The discussion includes both technical inquiries and historical reflections without resolving the initial question.

Contextual Notes

Some assumptions about the availability of materials and the historical context of electronics are present, but these are not fully explored or resolved within the discussion.

Who May Find This Useful

Individuals interested in electronics, DIY projects, or the historical development of rectifiers and electronic components may find this discussion relevant.

Hi:biggrin: ,
I am again, I want to know How I can make simple rectifier, If you can give me graph for rectifier.

Thanks
I appreciate it :approve:
 
Engineering news on Phys.org
I googled the following for you:

+rectifier +tutorial

and got lots of hits. The first one looks pretty instructive. Hope that helps.
 
if he's asking how to build a pn junction i'd think he'd have a hard time getting doped silicon, geranium would probably be easyier, i found a link for a homemade tube diode. maybe I'm reading to much into this. :rolleyes:
 
Beckeman,

Have you ever seen the old selenium rectifiers.

I thought the packaging was cool.

LOL, Don. That's almost surreal. I wonder who the heck the customers were for this stuff...

from what i know back in the day most people would take there tubes to the local hardware store, use the tube tester and buy tubes as needed. working with electronics seemed to have a lot less of a nerdy image back then to.
 
Berkeman, you're forgetting that in the old days of electronics it was not uncommon at all to be replacing parts in TVs and radios quite often. I'm sure these sort of things were sold wherever tubes were sold. Quite likely at the corner drugstore.

That's funny... What you said brought back memories from my childhood (late 60's?) of seeing Tube Tester stations in some stores. You'd plug in your tube to see if it was weak, and then you could buy replacement tubes there.

Anyway, sorry that we hijacked your thread, OP. Did you get what you needed?
 
How did karim102 make out with the simple rectifier?
Perhaps karim could get some http://mineral.galleries.com/minerals/sulfides/galena/galena.htm

Hi,
thanks a lot Ouabache, it is so great, I will do it so soon.
I appreciate it man
