Parts are KEY!!! Crucial Items. - A real soldering station. - Solder - ALL THE RESISTORS - ALL THE WIRES (Solid core is really handy for mocking with breadboards - A good multimeter - A good power supply - Breadboards - Shrink tube I think that covers the main things. Also nice to have are - Heat gun - fume hood (this is overkill for a hobbyist probably) - Oscilloscope (I hear they are getting nearly affordable) - Crimps (molex) - A real crimping tool (Not pliers. One of the ratcheting ones.) - All the other stuff I forgot about.

I can't emphasize the following enough: > A real soldering station > Solder Get a good, name brand soldering station. Yes it will cost a few hundred dollars, but it will make a huge difference in your work. The cheap-o $15 soldering irons all produce horrible results and will shatter your confidence... Get good, very thin solder. It will be expensive ($40) but will last forever and if paired with a legit soldering iron, will make a huge impact in your abilities.
- fhood 9y ago
  I don't think you even need to spend a few hundred. ~100 will pretty much do the trick.
- silasb 9y ago
  I've looked around for a good soldering station and the best thing that I could find for the price/performance is the TS100. All the other budget (sub $100) didn't have a direct heating element. In total, I probably spent about $100 to get a stand and other things needed for soldering.
  - jeff_vader 9y ago
    I'd second the TS100. It's ~$40 (given you can find a power supply for free, laptop bricks work fine. I'm using mini photo printer power supply which I found on the street + $1 plug + $3 worth of heat resistant silicone cable). Warms up in seconds, open source and customizable firmware, takes very little space (kind of important to me since I don't have a dedicated shed/garage for the hobby). What's not to love about it for a beginner?
    - stigi 9y ago
      Honest question: Why does a soldering iron need a firmware? Isn't it just enough to set a temperature? What other features are there?
      - gh02t 9y ago
        Apart from reading the buttons that control the device and writing the display, a digital iron needs firmware to control the feedback loop that maintains the temperature. Digital irons generally have PID based temperature regulation, unlike the crappy analog ones that have open loop systems (some analog irons have temperature regulation, e.g. Weller's old magnetic tips, but the crappy $5 irons do not). This requires a controller to supervise, but also means the iron heats up much faster and maintains that temperature while soldering. Other features like a temperature graph or adjusting calibration and control parameters are handy additions when you have a nice display like in the TS100. Realistically though, people aren't really writing their own TS100 firmware with the exception of a few tinkerers. What it comes with is good enough.
    - kc3 9y ago
      Can you say where you can find a TS100 for ~$40? The cheapest I'm seeing is $50-55. Also, are there different versions you need to worry about or are they all the same? I assume you only want a "MINI TS100" vs. some of the other knock off brands.
  - pmorici 9y ago
    why bother with that when you can get a name brand adjustable temp iron for ~$100?
    - Viker 9y ago
      I would actualy argue that the "MINI" TS100 is a name brand. Build Quality is Great. Preformance is on par with Hakko and Weller. Also they have other great products. The MINI Nano DSO203 is a great 4 Channel Digital Oscilloscope for around 100 USD... Also the Mini ES 121 is a piece of art screw driver :) So yehh... I say it is a name brand ! And the Brand is "Mini"
      - jacquesm 9y ago
        I could not recommend the DSO203 in good conscience, it has almost no isolation of the input channels which makes it downright dangerous. It's nice if you only do audio or low voltage stuff but the first time you're going to point your probe at something a bit more beefy and you will let the magic smoke out (good case) or worse.
    - schwarze_pest 9y ago
      Because there are none. Please show me a name brand direct heating element soldering station for $100. I would like to buy one.
  - cerebellum42 9y ago
    I use a Weller W61C (80-90€), which is a soldering iron (not station) that regulates its temparature using magnetic tips. Bit of an oddball, but it works fine even for soldering most SMD stuff, and it's just delightfully simple. Just plug it in and start soldering. Takes up basically no space too, since it's just a soldering iron with no station. For really fiddly SMD items I have a cheap hot air rework station, but I don't need it very often - mostly when I have to desolder something SMD or solder on an IC with a thermal pad on the bottom.
- archgoon 9y ago
  > name brand soldering station What's a good name brand for soldering irons?
  - coryrc 9y ago
    Weller. Though I have a Aoyue hot air station and it is great.
  - NegativeLatency 9y ago
    Hakko
  - Kelbit 9y ago
    Get either a Hakko FX888D or a Weller WES51. I personally prefer the Hakko, but both are excellent stations that cost under $150 which will serve you for years if you take care of them. A note - soldering stations usually come with a cheap conical tip as a starter tip. Pay an extra $20 or so to buy two chisel tips: a tiny one for fine work, and a big one for larger work. The flat surface allows you to apply more heat to the joint. Take care of your tips (ie: keep them tinned, don't leave the iron on too hot, and don't scrub too hard with the brass sponge) and the tips should last a few years without trouble.
    - Gibbon1 9y ago
      The WES51 as a solid soldering iron. You can get ones with a display readout but it's less useful than you might think. Most of the time you just set the temp and then switch tips if you need more or less heat transfer. Need to solder something large or stubborn? Using a phat chisel tip is better than upping the temp. Too hot and the rosin quickly oxidizes and turns to varnish, which prevents the solder from wetting. Also tips, get a hooked tip, about 80% of the time it'll do the job.
    - mikro2nd 9y ago
      A thing to say in Weller's favour: They stock parts forever. My Weller station is somthing like 35 years old, now, still works perfectly. But someone damaged the sleeve that holds the tips in place. No problem, for a modest cost I could still buy a replacement, even though that particular part no longer fits any contemporary model of iron Weller sells. Kudos to them!
- crtlaltdel 9y ago
  buy a weller and use appropriately sized solder for the application (very thin solder sucks really bad if you are doing something like throughhole or larger parts...you will have to apply the heat longer to apply enough solder)
  - mindslight 9y ago
    IMHO thin solder is also annoying on larger joints due to less of a flux core.
- ninjakeyboard 9y ago
  +1 I was using thicker solder for a while and it was a mess. Getting thinner 60/40 flux code made a HUGE difference in my ability to build boards. It doesn't have to be super thin but thinner is 100% better than thicker.
- cr0sh 9y ago
  > The cheap-o $15 soldering irons all produce horrible results and will shatter your confidence... I would make the opposite argument that if you can get great results from a cheap-o soldering iron, your confidence and ability will soar thereafter. Recall that, back in the really early days, soldering irons were large affairs, consisting of a large block of copper heated via a gasoline or kerosene torch, with a large wood handle and a steel shaft: https://www.stevenjohnson.com/soldering/pics/old-reliable.jpg https://www.stevenjohnson.com/soldering/pics/old-reliable.jp... Electrical ones weren't much better: https://www.stevenjohnson.com/soldering/pics/ge-1911.jpg https://www.stevenjohnson.com/soldering/pics/ge-1911.jpg Now granted, connections were mostly "free-air" and not PCB based or similar. Also, some of those irons were meant for soldering sheet metal, not really electronics or electrical work - but that's what people had at the time... When I learned to solder thru-hole electronics, I learned with what could be called a "cheap-o" soldering iron; something like this (maybe not as nice looking): https://www.circuitspecialists.com/content/image/104526/600/sh-813a-220v-0.jpg https://www.circuitspecialists.com/content/image/104526/600/... I still have it, and still use it occasionally. It takes "forever" to heat up (about 10-15 minutes), and the tip looks like hell. But for thru-hole construction, it works great. Once you know how to use it, you can solder like a champ. Would I use it for SMT rework? No. Basically it's virtually worthless for anything with less than 0.1" pitch, unless you're removing parts and just need to dump a lot of heat in a small area. The key to successful soldering is knowing how to control and place the heat where you need it, and flowing the solder into the joint properly. Most make the mistake of not tinning their iron or the part leads, then trying to flow the solder using the tip of the iron, where all it does is stick the iron tip. Instead, you have to heat the component's lead(s), and flow the solder using the heat on the lead(s). Tinning both the iron and the leads helps with this as well. Flux can also help, but if you use a decent flux-core solder (preferably 63/37 ratio tin-lead), flux should rarely be needed. A paste flux is useful though for cleaning the tip of the iron, especially when shutting down for the day. It's kinda like arc welding. Sure, MIG can be easy to learn. But if you really want to understand, start with rod (stick) first. Yeah, you'll stick the rod continuously, cussing a storm up at first. But after a while, you'll develop the knack of keeping that weld pool just right and moving the rod while feeding it in, without sticking. Once you've done that, MIG is nothing...

  I have a $99 100w Duratech one and it's perfectly adequate, no different from the $400+ Weller ones I've used in the past. If you're just doing a bit of soldering as a hobby, though, get leaded solder. It works so much better than the modern unleaded stuff. Just don't breathe the smoke.
  - lsc 9y ago
    >If you're just doing a bit of soldering as a hobby, though, get leaded solder. It works so much better than the modern unleaded stuff. Just don't breathe the smoke. That is personally not the tradeoff I'd make. Lead is a special kind of poison in that it makes you stupid before it kills you: This is especially true of children, but I don't want any of it on my adult self, either. Note, you can also buy lead-free 'low temperature' solder, which has a lot of the same properties of lead solder, though it's more expensive.
    - cerebellum42 9y ago
      As far as I know, many lead free solders produce more toxic smoke than leaded solder because they contain different types of flux. When soldering the leaded stuff, the lead in it doesn't get evaporated anyways. The smoke produced during soldering is mostly evaporated flux. "don't breathe the smoke" is just generally good advice, and it definitely doesn't become less applicable if you use lead free solder.
      - lsc 9y ago
        I need citation on this idea that flux is just as toxic as lead. Being a technician, I read the MSDS: https://www.mgchemicals.com/downloads/msds/01%20English%20Can-USA%20SDS/sds-4900-4917.pdf https://www.mgchemicals.com/downloads/msds/01%20English%20Ca... vs: https://www.mgchemicals.com/downloads/msds/01%20English%20Can-USA%20SDS/sds-4860-4867.pdf https://www.mgchemicals.com/downloads/msds/01%20English%20Ca... I mean, I ain't saying you should lick either one... and yeah, I don't know how much if any lead is released into the air during normal operation, but lead is pretty seriously toxic to humans, and avoiding touching the lead as I'm using it sounds kinda difficult. The flux? yeah, that isn't any good for you either, but I don't think it's in the same category as lead when it comes to toxicity.

  or get a hakko clone from aliexpress. half the price and just as good in my experience.
stingrae 9y ago
I would add a logic analyzer before oscilloscope. You can get good ones for pretty cheap now. https://www.saleae.com/ https://www.saleae.com/ It is so nice to be able to see what is actually going on when debugging interfaces.
- keithnz 9y ago
  for learning electronics? why? I'd say an oscilloscope way before a logic analyzer as it allows you to see what circuits are doing. Learning what analog circuits are doing is much more useful for learning than seeing digital signalling.
  - stingrae 9y ago
    I think most people getting into electronics won't be doing analog designs. They'll probably be messing around with various sensor devkits (sparkfun, adafruit, etc.) and Arduinos/RaspberryPis/ESP8266. With these you'll be messing around with primarily I2C and SPI which is why a cheap logic analyzer is cool also they are much cheaper than an oscilloscope and some have some analog functionality.
    - keithnz 9y ago
      maybe, but even with those, unless it's because you really want to look at I2C / SPI, mostly that just works. I'm not sure what people mean when they say they want to learn electronics, whether they are talking about getting a micro based kit and hooking things up to it and programming it or whether they want to understand circuits and components and how they work. If it's the latter, then go with a scope.
    - tzs 9y ago
      > With these you'll be messing around with primarily I2C and SPI On the other hand, if you get the right cheap oscilloscope, such as a Rigol 1054z, which goes for $350 [1] and add the $180 "serial bus analysis" option, the 'scope will know how to trigger on and decode I2C, SPI, RS232 protocols. If you don't mind using cracks, you can enable the serial bus analysis option for free, and also double the memory and the bandwidth. Rigol's response to the crack is interesting. The cracks work because they used a key length for a cryptographic key in their firmware that is short enough to fairly easily brute force. It's hard to see how this could be accidental. Further suggesting that it is not accidental is the fact that they could have easily fixed this once people figured it out, but they have not. That has led to speculation that they purposefully did this, so that hobbyists could easily crack the thing and get all the features. Professional users could also crack it, but they would be reluctant to do so, because of potential liability issues. If you are a pro, and you design something the ends up used in a system that causes harm, and it comes out you were using hacked test equipment, the plaintiff's lawyers will be all over that. If that is the case, it was an excellent strategy. Over on /r/electronics or /r/AskElectronics, you ask for a 'scope recommendation as a hobbyist or student, and almost all the responses will say get the DS1054z and crack it.

For those low on cash, or who want to dive in a little before seeing what soldering station, multimeter, power supply, oscilloscope etc. they want... First buy a breadboard (or more than one). Buy the resistors and wires you need in the near future. You'll need a crimper pretty soon to cut the wires. A good power supply is nice, but you can make due with a battery holder and battery at first, say, a 9 volt. Look at some simple projects you can build, and get the capacitors, LEDs, inductors etc. necessary to build them. When you want to start soldering things together, get a soldering station, solder and stripboards. Also get solder flux . Soldering is much less of a pain when you have flux, depending on what you are doing. As the comment section here attests - a soldering gun is hot. Solder is hot. You have to be careful. Digikey.com and Mouser.com have many, many electronic parts. Adafruit.com has a lot of cool projects and guides. In fact, I would recommend you watch some Adafruit videos, read some of their guides etc. After you learn some of the basics, you can take a step up and get an Arduino and muck with that.
- kevhito 9y ago
  Digikey can be intimidating. The interface is kind of clunky, and for a beginner (like me!) it's overkill when you just want a couple of 10uF capacitors but get 60,000 hits for every variation of exotic capacitor ever made, and pricing for units of 1000s. I find jameco.com very friendly for a beginner. Prices are about the same as elsewhere, shipping is fine, selection is fine for a beginner, and usually it's usually pretty easy to narrow the search results to just a few parts that have fairly clear differences. They have a pretty nice email newsletter too, essentially the only newsletter I allow through my spam filters, and the only one I've ever clicked on non-accidentally. The regularly feature hobby projects on their front page, from premade kits to more advanced stuff.
lightedman 9y ago
"fume hood (this is overkill for a hobbyist probably)" PPE is never overkill, and flux from soldering is really nasty stuff to inhale over time.
ThatPlayer 9y ago
I found my set of Engineer PA-09 crimp pliers does a better job than one of the cheap ratcheting crimping tools. Got them to do the smaller JST crimps, but they do Dupont pretty well too.
chrsstrm 9y ago
The last time I looked into power supplies they were somewhat cost prohibitive for my twice a year hardware project habit. Have things changed? Are there some good bang for your buck supplies that can be had for a couple hundred bucks or so?
- smoyer 9y ago
  I've got dozens of P/S from old computers that put out plenty of 5VDC as well as +/-12VDC. One good bench supply should be enough these days.
  - chrsstrm 9y ago
    I was referring to a bench supply, although maybe I should have looked before asking. The number of DC bench supplies available in the $100 range is huge. This seems like a big price shift over the past couple years.

Add an anti-static mat and wrist strap to that list!

I mean, I ain't saying you should lick either one... and yeah, I don't know how much if any lead is released into the air during normal operation, but lead is pretty seriously toxic to humans, and avoiding touching the lead as I'm using it sounds kinda difficult. The flux? yeah, that isn't any good for you either, but I don't think it's in the same category as lead when it comes to toxicity.

or get a hakko clone from aliexpress. half the price and just as good in my experience.

I would add a logic analyzer before oscilloscope. You can get good ones for pretty cheap now. https://www.saleae.com/ https://www.saleae.com/ It is so nice to be able to see what is actually going on when debugging interfaces.

keithnz 9y ago
for learning electronics? why? I'd say an oscilloscope way before a logic analyzer as it allows you to see what circuits are doing. Learning what analog circuits are doing is much more useful for learning than seeing digital signalling.
- stingrae 9y ago
  I think most people getting into electronics won't be doing analog designs. They'll probably be messing around with various sensor devkits (sparkfun, adafruit, etc.) and Arduinos/RaspberryPis/ESP8266. With these you'll be messing around with primarily I2C and SPI which is why a cheap logic analyzer is cool also they are much cheaper than an oscilloscope and some have some analog functionality.
  - keithnz 9y ago
    maybe, but even with those, unless it's because you really want to look at I2C / SPI, mostly that just works. I'm not sure what people mean when they say they want to learn electronics, whether they are talking about getting a micro based kit and hooking things up to it and programming it or whether they want to understand circuits and components and how they work. If it's the latter, then go with a scope.

    > With these you'll be messing around with primarily I2C and SPI On the other hand, if you get the right cheap oscilloscope, such as a Rigol 1054z, which goes for $350 [1] and add the $180 "serial bus analysis" option, the 'scope will know how to trigger on and decode I2C, SPI, RS232 protocols. If you don't mind using cracks, you can enable the serial bus analysis option for free, and also double the memory and the bandwidth. Rigol's response to the crack is interesting. The cracks work because they used a key length for a cryptographic key in their firmware that is short enough to fairly easily brute force. It's hard to see how this could be accidental. Further suggesting that it is not accidental is the fact that they could have easily fixed this once people figured it out, but they have not. That has led to speculation that they purposefully did this, so that hobbyists could easily crack the thing and get all the features. Professional users could also crack it, but they would be reluctant to do so, because of potential liability issues. If you are a pro, and you design something the ends up used in a system that causes harm, and it comes out you were using hacked test equipment, the plaintiff's lawyers will be all over that. If that is the case, it was an excellent strategy. Over on /r/electronics or /r/AskElectronics, you ask for a 'scope recommendation as a hobbyist or student, and almost all the responses will say get the DS1054z and crack it.

For those low on cash, or who want to dive in a little before seeing what soldering station, multimeter, power supply, oscilloscope etc. they want... First buy a breadboard (or more than one). Buy the resistors and wires you need in the near future. You'll need a crimper pretty soon to cut the wires. A good power supply is nice, but you can make due with a battery holder and battery at first, say, a 9 volt. Look at some simple projects you can build, and get the capacitors, LEDs, inductors etc. necessary to build them. When you want to start soldering things together, get a soldering station, solder and stripboards. Also get solder flux . Soldering is much less of a pain when you have flux, depending on what you are doing. As the comment section here attests - a soldering gun is hot. Solder is hot. You have to be careful. Digikey.com and Mouser.com have many, many electronic parts. Adafruit.com has a lot of cool projects and guides. In fact, I would recommend you watch some Adafruit videos, read some of their guides etc. After you learn some of the basics, you can take a step up and get an Arduino and muck with that.

Digikey can be intimidating. The interface is kind of clunky, and for a beginner (like me!) it's overkill when you just want a couple of 10uF capacitors but get 60,000 hits for every variation of exotic capacitor ever made, and pricing for units of 1000s. I find jameco.com very friendly for a beginner. Prices are about the same as elsewhere, shipping is fine, selection is fine for a beginner, and usually it's usually pretty easy to narrow the search results to just a few parts that have fairly clear differences. They have a pretty nice email newsletter too, essentially the only newsletter I allow through my spam filters, and the only one I've ever clicked on non-accidentally. The regularly feature hobby projects on their front page, from premade kits to more advanced stuff.

"fume hood (this is overkill for a hobbyist probably)" PPE is never overkill, and flux from soldering is really nasty stuff to inhale over time.

I found my set of Engineer PA-09 crimp pliers does a better job than one of the cheap ratcheting crimping tools. Got them to do the smaller JST crimps, but they do Dupont pretty well too.

The last time I looked into power supplies they were somewhat cost prohibitive for my twice a year hardware project habit. Have things changed? Are there some good bang for your buck supplies that can be had for a couple hundred bucks or so?

smoyer 9y ago
I've got dozens of P/S from old computers that put out plenty of 5VDC as well as +/-12VDC. One good bench supply should be enough these days.
- chrsstrm 9y ago
  I was referring to a bench supply, although maybe I should have looked before asking. The number of DC bench supplies available in the $100 range is huge. This seems like a big price shift over the past couple years.

smoyer 9y ago

Add an anti-static mat and wrist strap to that list!

auvrw 9y ago

i suggest (as someone who still knows nothing about electronics) that oscilloscopes are a "must have." cathode-ray-tube style from ebay are more affordable. also, Horowitz and Hill, to echo what i suppose is mentioned elsewhere.

jacquesm 9y ago

You can pick up good scopes from army surplus. That's how I got my Tek.
