Don't be silly. There's no "fail" to these very informative videos.
To solder successfully, use a separate flux always. No flux-core solder has enough. Kester 951 is water-thin, while Radio Shack sells a gel. Either is fine. I really gotta make a vid about using flux.
I appreciate the comment, even though the tone is unnecessarily negative. I'll revise the video before using it again with some additional comments about my technique, and try and improve it for the future.
If you decide to create educational resources of a higher quality that are more correct, please let me know. Until then, I appreciate your feedback, and will try and do better in the future.
Also, I advise anyone trying this to wear safety goggles because snipping those wire leads with a good diagonal cutter will make those wire leads launch like flying needles. Get one in your eye and you can become severely injured. Keep other people out of the area where you'll be doing this assembly work. They can be injured by flying wires too. Molten solder can pop or splash unexpectedly which is another reason to wear eye / face protection, and keep others out of the work area. Professor?
@xxM5xx You're correct, and I do require my students to use eye protection when we're working. It might not be in the video, but remember that these videos are not 100% of the context.
So you know, in class I pointed out that many of my solder joints (and, I said this in a later video) use too much solder and too much heat -- which I re-iterated in class.
I don't know how much work you do out of your area of expertise. I figure I'm doing pretty well, considering.
FAIL. The person soldering spends WAY TOO MUCH time heating each joint. I also disagree with the directive to clip the lead wire before soldering. The lead pulls heat way from the component quicker after soldering (better for the part) and reduces the chance of heat damage to the component, esp. diodes, transistors and ICs. This is a good video on how NOT to assemble a circuit board, and this is published by a college? FAIL. You hear me Professor? Programmers....argh.
beautifully done! The humor and honesty only enhances the quality of the video and lesson

@pickbuck If you do a flux vid, do let me know. Otherwise, I'll try and remember to work that in the next time I do a video like this. Many thanks!

PS: Flux can be expensive, but a little goes a long way. Kester 951 is sold in small quantities by some people on eBay.
