  • I use the database in PADS to select parts that I have in stock, or will be ordering. The part number system makes it easy to select parts for new designs, and they are in the same order in the envelopes in the drawers.

    What I did yesterday (Wednesday) was to drive my truck up the rough access road to the upper meadow, load it with firewood, and drive back down to a spot near my house. Today I unloaded some of it, split a big locust log, and covered the load with a tarp in anticipation of yet more rain predicted for Friday. We've had about twice the normal amount this year, and several inches more than the record 61 inches set in 1889.

      As I've said, I've been there, done that... not quite the collection you have, but the same approach. It didn't work for me.

      Been working great for me and my son. I've got plenty of space/bins for expansion. If I get another IRF, I just peel the label off one of the IRF bins and print a new label in ~30 seconds that includes the new device with my hand held label machine.

      These label machines are really great. I use the small font which provides two lines if needed. I can turn the machine on, type in the text and print a new label in seconds and the old labels easily peal right off. I re-label bins all the time when I add new stuff to them.

        Maybe it's because my early career was based on the former... but I'd never put my kid through that I'll be happy if I get him into Arduinos, or whatever replaces them, in the next few years. He had fun with the automated railway crossing a few months back. Just a servo and a proximity sensor. Some flashing LEDs. Maybe I'll add a mechanical bell with a solenoid to spark that back up.

        Any luck with your kid so far? How old? Mine's 8 now, and it's still mostly "meh".

        And, sorry, I ditched most of my wire-wrap sockets or I'd have mailed them to you. Oh, by 'ditched', I mean I put them in the free-pile at work so the Electronics students can take them... and store them, and move them, and sort them for the next 30 years. Had one student come in asking if I had any 'old' computer components. I loaded him up. He came back the next day all sheepish... said his girlfriend said he couldn't keep them. Lucky guy, I needed a girl like that back then.

        My son loves electronics, computers, and programming. He's 11 now. We bread board everything. I keep the wire wrapping sockets and such but don't plan on using them except occasionally I'll push a WW socket into a bread board if I want it lifted up for some reason.

        • The last project I wire wrapped was an embedded 386ex computer. Before that was an embedded 486 DX2. Both running my own OS. It was lots of fun back in the 90's:

          • Well, damn. I was just starting in the IT industry when 486's came in. And I thought it was a pain in the backside to troubleshoot commercial motherboards! Got to admire your patience/sheer bloody-mindedness!

            What I've learned about parts storage from all this is that when doing a project, be it with fasteners or electronics....I need to come over to one of your workshops and do it there!

            How was everyone's "Ooh, while you're here...." Christmas load this year? I got away with moving an internal card reader, data and backup device, re-hanging a toilet roll holder and a multitude of kids toy assemblage. Have yet to make it to my mum's where I've already been warned that what she's bought my son has a 90 minute (adult) build time. I swear that's the main reason she chose it!

            • Insane wirejob! You sure have some patience and sheer luck if all of them are connected in the right place....

              My colleague is building a steering setup for a hydraulically driven radio operated tracked vechicle and his contraption looks pretty much the same times three in size. With two arduinos linking a remote control panel to hydraulic valve guides. Not to mention it does not work at all

              • What I did today? Traveled from Seoul, South Korea to Dubai in business class on an A380, followed by business class to Bahrain on a 777. Tomorrow evening I will fly as the pilot, a 747 to Hong Kong. Sorry, I'd much rather talk shop but can't when I am away.

                • Do you prefer to fly the plane on autopilot , because its cool to see the machine do its job, or do you like flying the aircraft ?

                  • Wire wrap is not THAT bad.... beats heck out of soldering the wires, IMO.

                    Done a good deal of both, myself. A PWB beats either of them, of course.
                    CNC machines only go through the motions

                    • I have done very few wire-wrap boards. I prefer using pad-per-hole plated through project boards and wire wrap wire cut and stripped to appropriate lengths, and soldered. I have also been using many SMT components on prototypes. Here is one example:





                      And this:


                      Here is a really simple "PCB" using adhesive backed copper tape and a couple SMT components, mounted on the leather cover of a checkbook:


                      If you can wait a couple weeks, you can get actual PCBs 10 pieces for five dollars:

                        Paul, you should get yourself a bunch of SMT adapter boards like these. I bought all of mine on Amazon:

                          I prefer to hand fly it down to a landing, and keep autopilot off after takeoff and hand fly it up to around 19,000ft. There is absolutely nothing fun about hand flying a jet in cruise, it requires constant control input to maintain altitude as it flies near its envelope. The airplane was designed to fly in cruise with AP on. As large as the 747-400 is, it handles like a sports car. It is very responsive only requiring a light touch.

                          • I remember being in the cockpit, on a flight to Europe, I think a 747.
                            Lots going on..
                            I learned a bit.. that day. A pilot I knew was flying that trip.
                            I sent word up front, after A while he came to join me for a while, Uniform jacket off, sweater on..
                            After a while a young flight attendant came up, and advised him to buckle up...lol..
                            Then I noticed the other Captain walk by and disappear to back of aircraft.
                            I looked at him looked at Andy the pilot beside me, then asked him who was flying the airplane ?

                            • I posted earlier in the week the first part of my coaster build. I try to make a shop made gift each year for Christmas gifts. This is the finishing up of the gifts. https://youtu.be/LFWA-xcHH3I
