Power Supply – Case Completion

November 26, 2010 13 comments


I’ve finished most of the construction and i decided that this project has taken longer than i’d hoped. I wanted to finish it so here is the final build and assembly in one huge post.

Parts Used:

  • My Adjustable Voltage Circuit
  • My Panel Meter Circuit
  • My Aluminium Supply Case (Labelled)
  • 2x DPDT switch
  • Green Binding Post
  • 4x Red Binding Post
  • 4x Black Binding Post
  • 3mm Red LED
  • 6x 3mm Green LED
  • 7x 3mm LED panel clips
  • 4P2T rotary switch
  • Amp Panel Meter
  • Voltage Panel Meter
  • Red Multimeter Lead
  • 2x 6mm knobs
  • ~20cm of 3mm 3:1 Heatshrink
  • 2x TO-220 heasinks
  • ~50 Crimp terminals
  • Lead Free Solder
  • 3x 47 KΩ resistors
  • 3x 5.6 KΩ resistors
  • 3.9 KΩ resistor
  • 820 Ω resistor
  • 12 KΩ resistor
  • 1.8 KΩ resistor

Tools Used:

  • Soldering Iron
  • Crimping tool
  • Snipe nosed pliers
  • Wire cutters
  • Glue Gun
  • Phillips screwdriver
  • 2mm Allen key

For most of this it should be clear how it goes together. The circuit construction just followed my power supply schematic. If there is anything that needs explaining further then feel free to ask. Unfortunately i got a bit carried away at some parts and forgot to take photos, I’m still learning to take my time.

Update – Electronics Tools

September 10, 2010 Leave a comment

Since its taken me a while to get the next stage of my bench power supply project finished, I decided it might be an idea to post another electronics guide. I’ve added a brief article to the electronics guide section on basic tools used for electronics. It will be expanded on later to include other useful tools as well as more advanced tools

I’ve tried to include links where further information can be found and where some of the tools can be bought in the UK, alongside a brief description. I’ll slowly expand these links and hopefully you will find it useful.

impatience + soldering iron = smoke

While wiring up another circuit at the dining table last night I rushed and connected a chip the wrong way around. Will have to order some more now and with a minimum order value from the supplier, it looks like I’ll have to order some parts for future projects too, so look forward to some new projects being posted soon

It just shows that rushing these things only makes smoke and leaves you with a useless circuit
