Portable Soldering Station

Following up on getting the new hobby desk and organizing the room, I needed something for all of my soldering tools. A lot of the stuff on these shelves needed to be easy to pull out and use at the desk.

The portable soldering station Adam Savage built gave me some inspiration. I could make something to live in the closet when not in use and being portable would allow me to take it to the basement if needed. I measured how much floor space I had available in the closet and hauled everything down to my woodshop.

I cut up some shitty scrap plywood and started playing around with ideas.

Being able to see things in space really helped with my design process. When I had something I was happy with, I made a sketch with rough details.

When I saw it on paper, it reminded me of a wood toolbox with a handle. Makes sense, I guess, since that’s essentially what I was building. I still have a large pile of old oak flooring, so I spent about two hours milling a few pieces down to 3/8″ thick boards. Then I glued some pieces to make panels for the sides, bottom, and shelf.

I picked up a piece of 1″ (it’s actually 1 – 1/8″) oak dowel from Menards for a handle. After letting the glue dry on those panels for a few hours I cut them to size, designed the side profile, and made other pieces. I realized I need to glue up two other panels for the small shelf bottom and a cross piece on the back. I think I only had to recut one small piece that was originally the wrong size. Eventually I had all of the parts.

I sanded all of the faces with 80 grit and then used glue and a pin nailer for assembly. Since nothing here need to support a lot of weight, I went with simple butt joints.

After a quick fit check for all of the tools and supplies, it was obvious I need some way to organize the power cords, so I made a cord wrap from some scraps.

With a palm router I softened the edges everywhere and did a final sanding. Originally I was planning to use a dark stain to match the hobby room’s trim, but after seeing this put together I really liked the lighter colors and the wood grain. I skipped the stain and applied three coats of Minwax Water Based Polycrylic, sanding with a piece of paper bag after each.

I’m really happy with the decision not to use stain. The pieces I selected for the side panels have some great coloring and grain.

All of the tools and materials are easy to access and the station fits well in the closet.

Boldport: LIGEMDIO

A couple of weeks ago I assembled one of the BoldPort Club kits I had piled on my desk. This one was project #8, titled LIGEMDIO. It’s an LED tester and the name comes from the first letters of Light Emitting Diode, LED.

It was a cool little build after I swapped out to an old soldering iron and it’s a project I’ll actually get some use out of. Would have been nice to have when I tested all of the LEDs for the 8x8x8 cube.

HackerBox #0028: JamBox

I like it when the new HackerBox shows up on a weekend.

I always see electronics projects for making some kind of digital synthesizer to generate sounds so it seems to be a common project. It’s one I’ve never done, so I’m looking forward to experimenting with this box.

The official content list from the Instructable:

  • HackerBoxes #0028 Collectable Reference Card
  • Exclusive JamBox Printed Circuit Board
  • ESP32 DevKitC
  • CJMCU PCM5102 I2S Digital-to-Analog Module
  • Four MAX7219 8×8 LED Matrix Modules
  • Five 10K Ohm RV09 Potentiometers
  • Five Potentiometer Knobs
  • Eight Tactile Momentary Buttons
  • Four Adhesive Rubber Feet
  • 3.5mm Audio Patch Cable
  • MicroUSB Cable
  • Earbuds with Case
  • Exclusive HackerBoxes Skull Decal
  • Octocat Fan Art Decal Sheet

Unfortunately the demo code included in the guide only uses the potentiometers, buttons, and LEDs. Will need to do some tinkering to turn this into a synth.

A Raspberry Pi HAT

I successfully built the second piece to a large project I’m working on. I’ve essentially built my own XL Raspberry Pi HAT (Hardware Attached on Top). Since I’m not following the specs, I shouldn’t really call it a HAT.

I’m not sure how, but once again I correctly connected everything on the first try. Either I’m extremely lucky, my attention to detail is paying off, or a combination of the two. I’m just waiting for some catastrophic failure to happen soon when I solder things the wrong way one of these days. Every one of my solder bridges worked. I did run continuity tests on all of the early bridges, which I’m sure was a big factor to my success.

Any guesses on what this board does? Leave your best guess in the comments. It’ll be at least a month before I share more details because I need to finish the entire project first.
