I was in the RCAF as a Comm/Radar Systems technician and I took the High Reliability Soldering course developed by NASA. We were taught to put a small dab of liquid flux on the connection, and put a little solder on the tip. That solder then acts as a heat bridge as it comes in contact with the lead and the pad. This heats up the connection quickly so that you can apply solder to the opposite side of the work and minimize the possibility of heat damage to components and board. With 2 sided boards and plated through holes you must ensure to dwell long enough for the solder to flow to the other side. Also, on the subject of bending leads, leads are bent to be in centre of holes so they don't stick to the sides when trying to remove them. Not a big worry for most hobbyists however. Love your channel. Don't let the smoke out.

I've seen a bunch of commercial boards which have short leads (like the ones on buttons.) bent on opposite ways, so like 1 up 1 down on a capacitor, or up down up for transistors, it's still fairly easy to remove (either bend the leads straight with a screwdriver or the soldering iron, or twist the component out), but holds well when soldering.

Kits are a lot of fun, I just finished, perhaps the hardest kit I have seen on Ebay, finished her yesterday, installed the 5 required 1220 cells and pressed the button, and to my absolute amazement, she came to life and I have a working digital watch, all SM construction, the processor had such fine legs on it that I thought I would never get them separated as the solder refused to come away, it was bridges of Perkins County (where I live, not Clint,) and I pumped enough heat into that ST micro device that I figured it would never have survived the torture. Well took me a full day, I believed I was saved by ordering one of those little brass shavings thing for my soldering iron (ordered a new one of those to so I had some better equipment to finish the project. I did manage to break one of the holes away on the clear plastic frame but some glue fixed that. I wore her now for a couple of days, but she is rather fragile and I don't see her as an everyday watch, but one to wear when I am visiting others of the geek religion. Here she is, order one, they are only 10 bucks and tons of SMD practice for your price! They even tossed in 1 extra resistor and cap, I needed one as I got carried away with the resistors and had to remove one to replace it with a more powerful one, screwed it up, thank god for the exxtra.

I read a lot of reviews of it, and people complained that it only has 24 hour time, which is what I prefer, and it only displays the temperature in Celsius, and I guess this is America, but it's still not a big deal to me. Additionally, it comes with a QR code that points you to a website with build instructions that are all in Chinese, but it was easy to figure out with the pictures. The only thing I really didn't like about it was the beeper, so I "adjusted" it by jamming a pointy object inside it and wiggling it around until it became much quieter. Good times.

The description of one of them implies it is programmable via the USB interface (maybe Clive's is too) or maybe it just infects your computer with a virus when you try to program it. The description of one of the ring o' LEDs jobbies had this jem (amongst others): "In the previous version, many children's shoes said that the alarm time was too long, but many children's shoes said that the alarm time was too short.

the DS1307 is a good chip and keeps time perfectly if it runs from a good 32kHz crystal - limited only by the behavior of the quartz, such as its temperature coefficient which is normally optimized for 25°C operation in a wrist watch. That said I once got a batch of 20 counterfeit DS1307 from eBay which I wanted to use in a student lab. The chips were mostly not running at all, some of them went red hot after a short while. Yes, there are more advanced alternatives which now even have the crystal embedded and also correct for the temperature coefficient by adding extra timer ticks when needed (the crystal is slow when running at higher and lower temperatures). The quartz crystals also come with specifications for different load capacitances when bought from reputable manufacturers - the ones off ebay are usually unspecified, but normally the frequency deviation caused by the capacitive mismatch is negligible.

26:09 - One nice thing about the TS100 is it will work with anything from 10 to 24 volts (specs say 12 to 24, but it actually works down to 8.7 or so - although it heats up very slowly). That means you can use just three lithium cells in series and have a very portable kit (it will draw about 1.2A at that voltage, so cheap 14500s might not work; you'll probably need 18650s). It heats up noticeably faster with four (~14.8V), though. And at 24V it goes from room temperature (~15 ºC) to 300 ºC in about six seconds (and you can get really cheap boost regulators to get 24V out of three or four cells). Another nice thing is that the base of the tip (is that an oxymoron? or a cock joke?) doesn't get hot, so you can hold it about 5cm away from the tip, which is great for -fiddly- -frittery- precision work. For what you do on the channel, you'll probably want a BC2 tip, and then maybe a C4 and / or D24 for larger stuff. P.S. - If / when you decide to try out the one you have, don't be surprised if the "calibration" instructions don't match the manual. They seem to have been written for an older firmware. The current (OEM) firmware sequence to do calibration is: 1. Power off. 2. Let the tip cool down to room temperature (and don't hold it - the handle should be at the same temperature as the tip). 3. Power up. 4. Press B once to show temperature and voltage (if you don't see the voltage, you have an older firmware; upgrade or follow the manual). 5. Hold A *_or_* B (not both at the same time like the manual says) for about 3 seconds (the iron should then show "Cal_V"; if it shows "Cal_X", either the tip is defective or the handle and the tip were at very different temperatures). 6. Hold *_both_* buttons at the same time (not a single one like the manual says) to go back to standby mode (or click one of the buttons to go to other set-up options - holding down both exits the menu from any "page"). If you're using the Ralim firmware, ignore all that, of course, and just follow the instructions on the website (the current version is bugged and always displays ambient temperature as 0 ºC, though).

Many, many thanks for doing another kit-build video. I think they are my favourites! I seem to have a bit of a passion for clock kits, so I will have to get hold of this one! I wonder should you socket the micro-controller if you can then reprogramme it--get rid of some of the annoying behaviour in the process? However from the looks you would need to dremmel out holes for the higher-standing IC if you did. As it happens I just got from China a 100% SMT clock kit where the whole display matrix is made from something like 340 discrete LEDs. They will be a true pleasure to solder down I am sure! I think I might wait until I can get a TS80 with its finer bit specifically for the job. Those little irons seem to have an excellent reputation and sit just at the extreme top end of pocket-money prices. The difference from the TS100 is that it will run from a 'QuickCharge 3' compliant USB power supply, which is handy. Sadly, on looking I cannot seem to find this specific kit on eBay--would you mind putting in a generic link to it?

@schwartzenheimer16 жыл бұрын
In most PCB/SCH design packages, the square pad just means 'pin 1' of the component for purposes of netlisting and is usually pre-set in the supplied libraries. Since there appears to be a transistor driving the sounder, it would depend on whether it's NPN or PNP to determine the polarity (if any). Most likely, in this case, it's NPN, and the square pin should be negative.

Why do so many soldering irons come with spings to put them down in that are mounted in plastic too light to hold them down? The ceramic heater rods are very cheap, but I have to keep buying another soldering iron to mend the first one. I have my current stand stuffed with lead, but the spring still tipped the iron straight on the kitchen tiles. While waiting for a new heater rod from China for £2, I bought another almost identical iron, except this one had an on off switch in the handle,and the handle got hotter than the heater! Have you looked into the construction of soldering tips by the way? I had no idea they were so complicated, and that I had ruined many a one by trying to file it clean! :)

Clive, I've been guilty of carrying solder with an iron, but I always butter my joints and components with flux. I guess I have developed this technique do to bad experiences in my younger years of lifting traces and pads. I've found that if I carry solder over to a buttered joint, it reduces the chance of damage to the PCB, as I allow the wet tip of iron and solder to heat the joint via the solder, and the flux keeps joint clean. Of course, cleaning flux off after is a thing.. Also, this would only work if you add additional flux, which I never solder without using. Am I wrong?

In my experience, cropping leads very short doesn't matter when using quality leaded solder. I used to do it all the time and never had any problem until i went for high temp lead-free solder, as it's all they wanted to sell here for a very long time. It cracks very easily, especially if there's vibration and wide temperature variations. The DC-DC step-down converter i made 2 years ago for my car had cracked solder joints on most of the cropped leads in about 6 months. Cracks were aligned with the direction i cropped the lead in, so i guess compression too close to lead-free solder joint create tension, while leaded solder is soft enough to just displace. It's my hypothesis anyway.
