If you're taking your first steps into wiring, then you should get comfortable working with wires and tools. Here is a kit that will introduce you to wiring, soldering, etc.

Along with that, there are a few tools that might be useful to you:

  • A small stand with clips and magnifying glass
  • Solder wick for desoldering
  • Soldering tip cleaner
  • Extra supply of solder

    And there are videos on YouTube that will teach you how to properly solder a wire to a soldering point. For that Elenco kit, the main goal is to get both the siren and the flashing lights to work, which it will if you wired everything correctly and used the correct resistors. It can be easy to make mistakes while learning to solder for the first time but most mistakes can be fixed, and it's very difficult to cause enough damage to render the board completely unusable.

    Also, one note of caution: soldering irons are extremely hot, as the intent is to liquify the solder and attach it to the soldering points.

You should be able to clean off the pads, re-tin them, and re-solder new wires to them.


You'll need a few tools:

  1. Take some paper towels, fold them up into a square and get it wet with water. You'll use the wet paper towel to wipe off the hot tip between uses.
  2. Use the rosin core solder and apply some to the soldering iron tip.
  3. Wipe off any excess on the paper towel.


    Remove the solder from the pads on the heat bed:


  4. Clean the gunk off of the solder pads with the brass brush - the brass bristles should clean off the surface without damaging it, whereas steel bristles may cut into the surface a bit much.
  5. Unwind a few inches of the desoldering wick (copper braid), and dip the end into the rosin paste flux - you don't need a lot. The rosin helps the solder to flow and keeps impurities out.
  6. Put the desodering wick on top of the solder on the pad, and then press the tip of the soldering iron on top of the wick until it heats up. For an adjustable soldering iron, 300F is about right - you want the solder to melt within 5 seconds or less, ideally.
  7. The solder will melt, and get sucked up into the wick. Remove it from the pad while the solder's still hot
  8. You should be left with a bright shiny tinned solder pad.


    Add some solder to the pads - you'll want a little bit of solder to cover the whole pad, with enough to make a small bump.

  9. Take the solder, and touch it down flat on the pad.
  10. Place the soldering iron tip on top to melt it. Feed a little more solder in while it's hot, if needed.


    Tin the wires:

  11. Cut off the ends of the wire, and strip off the end of the insulation by about 1/4"-3/8".
  12. Twist the end of the wire so that it's tight, and straight.
  13. Cut off a small piece of the solder (~1/2"), and wrap it around the wire
  14. Dip the end of the wire into the rosin flux - you don't need a lot.
  15. Touch the soldering iron tip to the solder and the wire, and coat the wire back and forth until the solder gets sucked into the wire.
  16. It should have enough solder so that it gets absorbed and you can still see the outline of the wires.


    Attach the tinned wires to the tinned solder pads on the heat bed:

  17. Dip the tinned wire into the flux paste again - a little goes a long way.
  18. Place the tinned wire down on top of the tinned solder pad.
  19. Press the soldering iron tip on top of the wire, and heat it until the solder melts on both the wire and the pad.
  20. There should be just enough solder so that the wire is attached to the pad, but isn't buried in solder. If in doubt, add a little more.
  21. Hold the wire in place, and remove the soldering iron tip. It should cool in a few seconds, locking the wire in place.


    Also: You can use some isopropyl alcohol (rubbing alcohol) to clean up the excess rosin paste - it can get sticky.


    Hope this helps!

Well, if you can use the lab and it has a scope in it then you just scored big time.

As far as $100. I would get:

(amazon links for convenience, use any supplier you wish)

  • DMM (digital multimeter) - must have diode check, DC volts, AC volts, Ohms, and continuity. Extech EX330 ($50) or Equus 3320 ($20)

  • clip leads for the meter such as these - these are important because you will need to take values while the amp is on, and you don't want to be poking around a live amp

  • variable power/temp soldering iron - cheap one good one better one

  • 60/40 leaded solder - I like this kind

  • desolder braid

  • rosin flux

  • contact cleaner

  • (de-oxit d-5)[]

  • flush cutters

  • solder sucker

  • shrink tube of various diameters

  • 92%+ isopropyl alcohol

  • windex

  • q-tips

  • paper towels

  • needle nose pliers

  • nice set of phillips head screwdrivers

  • standard screwdriver

  • miner's headlamp

  • digital camera for taking many many pictures before and during disassembly

  • printer for printing service manuals

  • heat gunor hair dryer

  • canned air

    EDIT: Light bulb socket, 100W + 60W real light bulbs (not the hippy engery saving kind), electrical outlet - these are for making a dim bulb tester.

    All I can think of right now.

60/40 rosin core should be good.

Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces)

Use solder wick and a wide tip to clean the old solder off

NTE Electronics SW02-10 No-Clean Solder Wick, #4 Blue, .098" Width, 10' Length

Use lots flux. Coat the area before you use the wick and again before you solder. It helps bond the solder to the metal.

MG Chemicals No Clean Flux Paste, 10 ml Syringe

A good iron helps so very much. This is what I have

Weller WES51 Analog Soldering Station

However this should do for occasional use

Vastar 60W 110V Welding Soldering Iron with Adjustable Temperature Dial, 5pcs Interchangeable Different Soldering Iron Tips and Solder Tube for Soldering Repaired Usage, Blue

When you are done clean with 90% or above isopropyl alcohol and let dry before you use.

Watch some videos on how to use the wick. Its a great tool to have and works so much better than the crappy suckers.

u/GoldenShadowGS · 2 pointsr/multicopterbuilds

This is what I've been using to build my quads




u/Live-N-Let-Pi · 2 pointsr/Nerf

I wanna be unhelpful, too!

u/MrCrono666 · 2 pointsr/Gameboy

Hey! Glad to help. This Is the exact soldering iron I use. Extremely effective, I keep it at a 3 at all times, seems to be a legit temperature for everything Gameboy related.

The Solder I use works really well, rarely sticks to the soldering tip (like many other ones I've tried) and seems to be the most consistent. It's also supported by HHL - so you know it's solid!

Hope that helps.

u/cexshun · 2 pointsr/MechanicalKeyboards

If I had nothing and wanted to purchase decent quality stuff but still being affordable, I'd do the following.

Multimeter $45

Soldering Station $38

Solder $25

Desoldering Pump $6

If this is the only time you ever plan on soldering, then you can get away with the cheap stuff. You could probably source some of it locally for cheaper. None of this is great quality, but it will do the job for a 1 time project. While I wouldn't enjoy it, I could build an Ergodox with the following setup.

Desoldering Pump $6

Multimeter $13

Solder $9

Soldering Iron $8

Iron Holder $6

u/iandcorey · 1 pointr/StainedGlass

I started with 40/60 rosin core and then ran low so I bought the only thing I could get, this crap. I now know that rosin core was a mistake and that lead free isn't really popular.

u/risherwood · 1 pointr/AskElectronics

Thanks for sending the video along. I never knew what that little syringe was for until now.

I'm pretty sure the solder I'm using is for electric work. Here is what I've been using. I'll admit I pretty much never clean the solder tip which probably is having an impact on the ability of connections to stay put.

u/nazzjr · 1 pointr/MechanicalKeyboards

thinking about picking up the AOYUE 936 and this solder. will i need flux as well?

u/ThieF60 · 1 pointr/MechanicalKeyboards

This is what I've been using for a while. I generally like it, but it might have been a tad too big for this job. I really do think my main problem was pre-tinning both contacts before attaching a component.

u/levelxplane · 1 pointr/AskElectronics

It's a pencil type iron. I think that's what you're asking for.
Also, is this what I should be using?

u/kingofquackz · 1 pointr/Lighting

Do you mean something like this pencil solderer and this solder?
I've never done any soldering before so I'm not quite sure what I need to do. Would watching guides on youtube be enough for a simple soldering job like this?

u/TealCrimson · 1 pointr/MechanicalKeyboards

Gotcha, I bought Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces)

What's the best way to clean it up, any specific cleaning material or will some simple household approach work?

u/lauraskeez · 1 pointr/Guitar

That's really nice. What else would I need? Just solder and a vice?

u/IWannaMakeStuff · 1 pointr/arduino

Oboy, I'm probably the wrong person to ask. However, /u/BriThePiGuy recommends Joe Knows Electronics boxes, and /u/NeoMarxismIsEvil recommends the following:

> I would order some cheap assortment kits from people on aliexpress. These are the sort that come with like 10 of most common values of resistor, capacitor, etc.

> Other stuff:

> - WeMos d1 mini or mini pro
> - small i2c OLED displays
> - small LCD display
> - tacswitches (buttons)
> - SPDT switches
> - 74HC595 and 74HC165 shift registers
> - either bidirectional logic level shifter modules or mosfets and resistors needed to make them
> - 7 segment led displays (individual)
> - 8x8 led matrices
> - various environmental and physics sensors (often come as a kit of 20+ different modules)
> - extra breadboards
> - jumper wires
> - male and female header strips (for modules that lack pins)
> - cheap breadboard power supplies
> - voltage regulators (both LDO ICs and buck converter)
> - possibly some 4xAA or 4xAAA battery holders
> - trim pot assortment

> Those are just ideas. Some things like 7 seg led digits are pretty cheap and worth having a few of but not terribly important if you have a real display of some sort.

I personally like the assortment of bits I got in my Sparkfun Inventor's Kit, but found that I wanted more of the following:

u/thejoelslack · 1 pointr/soldering

If you need to solder on a pcb you'll want a temperature controlled soldering station, other essentials are rosin core solder, some flux to apply before soldering, and a helping hand to hold the pcb/component and wire in place when soldering. I leave my soldering station at a little less than 350 when I'm tinning wires and soldering on a pcb. Wipe excess solder off the iron, heat up the spot you want to solder to with the wire in place, then apply solder to the wire when the flux has smoked off, it should flow into the joint. You don't want to keep heat on a pcb for too long as it can damage components on the board. Make sure you tin the tip/s of the soldering iron with solder before and often during use, or the tips will oxidize and refuse to tin until you scrape the oxides off with a razor knife. Typically a problem at high temps, around 300C solder will melt and oxides form very slowly and the tip will stay hot without needing a retin for a 5-10 minutes. I usually set my temp on max when I first turn it on and hold a bit of solder to the tip and then turn it down when the solder melts. Saves a few minutes of warm up between use.

If you need to heat up a larger surface area (like a battery terminal) for tinning or soldering it helps to bump up the heat - sanding a large surface also will help. Steel and other metals may require use of a corrosive flux made specially for that.

That's about all I know XD

I suggest this:

It's a very good kit, and will give you plenty of practice before you solder your Poker 2. No frills, and will give you plenty of practice for through hole soldering.

Combine this with a practical, but good quality soldering station:

A desoldering pump:

And some solder:

To learn, there are plenty of Youtube videos, I recommend you also solder the Elenco kit, then desolder everything to get a feel for how the desoldering pump works (it's super easy, you can't really screw it up). Then, solder it together one more time for extra practice.

All together, about $66 bucks. Add in the cost of the switches, and you're looking at a little over 100. Still a bunch cheaper than the Poker 2 from Massdrop ($143.50), and you've just learned a life skill. For me, that's totally worth it, but then again, I'm an engineer, and learning useful skills is what my entire profession is based on.


EDIT: Get this soldering kit instead:

Cheaper and has more soldering points. The other one has a shitty speaker which doesn't add much to the soldering lesson, but drives the cost up.

u/SubEclipse · 1 pointr/hoggit

Hard to say... I personally enjoy doing little electronics projects from time to time, so in my case, I already had a soldering station on hand, and I use it probably once a month or so for various things. Chances are if you haven't needed a soldering iron in your life up to this point, that you will rarely have a use for one later on.

While it's certainly easy to spend a decent amount of money on a nice soldering station, a cheap iron like this one on Amazon would be fine for jobs like this. A small spool of solder will run you about $4 dollars. You could find similar prices to these at Radio Shack as well.
