- Trying something new!
I'm not the best at soldering PCBs. I'd like to get better at it, so what better way than to subject myself to comments on UA-cam?!
Or, alternatively, we can sit and chat while I work my way through a soldering project. This time, it's a BlueSCSI External v2. This device lets me use disk images on a vintage Mac (or any other SCSI device really).
I bought this myself from Joe's Computer Museum (not sponsored, just like his shop): jcm-1.com/product/bluescsi-v2... . Joe is also on UA-cam: @JoesComputerMuseum .
Lastly, you can check out the BlueSCSI project itself at scsi.blue/. It's definitely neat and will be featuring more in depth in a future video. Perhaps for #MARCHintosh down the road? - Наука та технологія
showing a smart person learning something new is a valuable teaching lesson
Thank you! I am trying to improve my skills in this space because I'd really like to be able to fix up more of my stuff.
You don't post enough.
I love watching Veronica Explains! 🥰
I was a NASA soldering instructor for years. Just a few tips for working with PCBs. Use 63/37 eutectic solder. Kester makes the best. The solder you were using looked pretty thick to me. Get some thinner stuff. Much easier to work with and control when soldering PCBs. I typically work with 625-650F, unless I'm working on something that requires higher heat ie. RF connectors or something that sinks a lot of heat. Also, sizing the tip to the work is crucial.
Loved watching! It was fun seeing you learn, and it's always cool finding new kits and projects. I have some soldering tips (har har) that have worked well for me:
I always prefer a toothpick instead of a q-tip for flux since I can be more accurate, and then I don't end up with strands of cotton sticking to my pins. The more flux, the better, though.
I solder way cooler than that (295°C) for Sn99Ag0.3Cu0.7 lead-free solder... There's tons of different alloys of solder with very different properties; it's worth a read through the "Solder alloys" article on Wikipedia.
Several years ago, I switched from a classic Weller style soldering iron to the Pinecil because the more direct heat (more direct contact between the heater element and the tip) seems to make things flow quicker and easier... And it's way cheaper than a Weller, too.
When you get a new tip, try to keep it shiny by tinning it whenever needed. If it starts getting dull, wipe it and use some flux to try to get it well tinned again.
Congratulations, you not only just learned THT soldering in just under one hour, but also came out with quite a respectable result. What I learned - especially form SMD soldering - is, that you don't really solder things, but you create the conditions for the flux and solder to do what you want. And there is no "too much flux". :-)
BlueSCSI looks like a useful tool going forward when I work on getting my old Amiga 2000 up and running again. At the moment I have the opposite problem. I have some physical SCSI (and IDE) HDs that I want to connect up to my computer so I can image the drives.
Lead boils at ~1.7k C so you don't really have to worry about lead exposure when soldering, just wash your hands and don't lick your soldering iron. The reason why we have RoHS and other regulations about lead in mass-produced electronics is mostly because disposing of lead-containing electronics is problematic, you can't just dump them in a landfill because it will leach out and contaminate ground water, etc.
Reasons I recommend fume extractor is for the flux fume. And leaded solder is harder to come by than lead free solder nowadays
Wait, you're not supposed to lick your soldering iron. Oops...
the fact you can even see, never mind solder those holes puts you way ahead of me. Enjoyed the video!
Diopter glasses from the drugstore can help. I use +2.0 for fine soldering
I don't solder a lot of electronics but using Kester 959T flux helped me a lot putting headers on Raspberry Pi's. Clean up is a breeze using this flux as well. Also .8mm dia solder worked the best (for me). I have the same soldering iron as you with the same tip. I've had good results soldering on Raspberry Pi's and ESP 32 micro controllers with this iron, but there are better ones out there for sure.
COBOL programmers - no matter how old or young - always have the ability to learn new skills, because of their uniqueness! 😋
Hi Veronica, I didn't master welding either, you have an extra merit for doing it live. 😊
Hoping Blue SCSI will prove functional for Flyer video recording when I get around to reviving my Amiga 4000 Toaster Flyer setup. The 4k Tower and Toaster parts were working the last time I fired them up 6 years ago for the Viva Amiga documentary premier at Georgia's Computer Museum of America. My 1084 monitor, however, started leaking smoke after a few hours of on time. 😪
WOOT!!
Looking forward to getting it cleaned up and utilized! Thanks for making it available in your shop!
I agree ADB is really good. I have never tried anything like this but I might after watching you. 👍
-40C = .40F. Had to start up a few more servers to keep the heat up...
From now on. You shall start every stream with pantomime. Oh and -25f as the sun was coming up this morning.
I have the Power Macintosh 6500/225. I've been thinking about the RaSCSI so it can emulate more than a hard drive, but also CD ROM and floppy and printer and network interface, then the pi is a proxy and netscape communicator gives the mac a modern unix environment though telnet and such. The Mac has the composite video input/output hardware, and the TV/FM tuner. The pi could pipe it's video into the mac and become the desktop background. I need to mount the Pi into the drive bay with extensions to the two slot brackets in the back, and an extension for the SD card to stick out of the Zip drive bezel along with a reset button, and a solid state drive could maybe be fastened to a blank card in a PCI slot. One worry that I have is that if I do all this then put all the plastic back on the case, then something goes wrong with the pi and I'll have to remove the plastic again risking damage. Maybe I should make an external enclosure. I'd rather it be all one piece though. I have two PCs from the same era I want to do similar with, one with Win 98 and the other a dual boot MS/Freedos.
We had -30 Celsius (-22 F) here in Norway the other day, brr.
-15c in case you're interested.
I would go with a 60/40 rosin core. That lead free might be better for your physical health, but your mental health will suffer. If forced to us lead free I would use a flux pen. Been soldering for over 50 plus years and I always just used a computer fan with a piece of charcoal filter strapped to the back with elastic bands. Also a small diameter solder and small tip for most circuit boards works better on PCBs.
Good advice. Flux fumes will get you long before lead toxicity. A better soldering iron makes soldering fun. Old Metcal or Pace irons work great with new tips.
Did you just say people not care for Linux....... You must say the following for forgiveness, We worship you oh mighty penguin and may you become sentient and if you do we worship you oh mighty penguin our loving overlord.
Now everyone Veronica did not say anything.
Oh lead free solder sucks so hard.
