What I Do For Fun

Well, there's more to it than that. :)

I got one of these for Christmas. It's a very cool 4-channel 50MHz 'scope that I hacked up to 100MHz. It's cool as hell and I've been having a ball learning about all it's doo-dads. I appreciate a tool with good doo-dads.



Which led me to get one of these (an arbitrary waveform generator). These are good for generating arbitrary waveforms. You know, because well-defined sine waves are just so boring. This is total and complete overkill for my needs (ham radio and guitar amps, mostly), but it's just so freaking beautiful that I had to have it. Plus it was on sale or something, but it's on back order.



Which led to one of these cheap on eBay because the nice one above is on backorder and I hate to wait. This one is a simpler sweeping function generator which is good for sweeping my generated functions.




And then one of the ones on the bottom because an analog scope is better for some stuff like impressing the babes. Babes love analog signal traces, and that's a fact.



And then finally one of these which is a bench-top multimeter that I really don't need because I have a nice fluke handheld, but that once can stay in my travel bag if I have one on the desk. It too, was too pretty not to buy, but there are some reviews of it being slow (supposedly fixed in firmware) so we'll see if it's a keeper.



Well, not really "finally" since I'm working on a deal for one of these, which is an isolation transformer with Variac for units under test to help me from destroying my scopes or killing myself. Probably.




The new white plastic stuff is all from China, and the things they're doing these days are mind-blowing. The first scope (the Rigol) was I think $400, and it's got features that would have cost $5000 back in the '90s. Wild. Meanwhile that old Tektroniks scope was $100 on eBay and sold for well over $2500 new. The Vector Vid was also about $100 and from the size of the outlets, I'm thinking it's going to be huge and heavy, but they just don't make stuff like that anymore, especially with a 10A capacity.

I'm completely rebuilding my home office and I'm tired of working on electronics on my computer desk so I'm building a real lab bench where I can fulfill my Rick and Morty destiny.

BTW if you haven't seen Rick and Morty, I highly recommend it. It's so un-PC that it's not even funny, which as it turns out is really funny. It can be pretty crude, so if that's not your thing you've been warned. Lauren thinks it's the dumbest thing ever, and I can appreciate that. :)

This is a scene from the show:



I was watching it with my kids and paused it at this scene and asked them as it struck me, "Is that how you see me?"

I pretty much got a resounding "yes". Well, except for the sociopathic tendencies and drinking problem. Mostly.

Well it looks like fun, just from all the knobs and lights and dials. I'm glad you're in your element. So what will you be testing first? And yeah, the Rick and Morty reference is appreciated. I am a big fan of everything that's irreverent about CN.

Enjoy your electronics,looks like you are going to be set up for a bit.
Do you have a current clamp meter to complete the ensemble as well.

I'll need to break something so I can go fix it. :)

I'm a guitar player (among other things) and I've been known to build amps from scratch and also repair old (1960s) tube amps. I also mess around with ham radios.

I have a Fluke 175 meter with clamp probes that I scored 10 years ago. Fun story: I work in computer networking and I worked around telecom guys at the time. The telecom guys had no respect for us because they were all about the electronics that most networking guys don't understand. I saw the new-in-box Fluke 175 True RMS meter siting on the director of telecom's desk and said, "nice meter!". He replied in a snarky voice, "If you can tell me what 'True RMS' means, I'll let you have it."

I proceeded to explain true RMS after which (to his credit), he raised his eyebrows and gave me the meter. He hadn't counted on a network guy being a ham radio nerd. :)

I also scored a VERY nice Fluke Butt Set in a similar fashion.

For those who don't know what a butt set is, it's the tool that the telephone guys use when troubleshooting phone lines. It's technically a "lineman's handset", but they've been called butt sets for as long as guys have hung them over their butts. :) They also use them to "butt into" phone calls. This is the one I got for free:



This time he asked what type of clips it had. They look like this and are called "bed of nails" clips:



He then stopped asking me nerdy questions that resulted in him giving away nice test equipment.

Free tools! I like that. Speaking of free...while you're tinkering, could you build me a theremin? LOL. I always wanted to give one a try. Probably could not master it since I can't walk and chew gum, but it would be fun to freak out my neighbors.

Nothing will freak out a dog like a theramin! :) I used to have a theramin app on my phone and the dogs would go berserk when the kids played with it.

For those who just got lost, this is a theramin. They were responsible for just about every sound effect in 1950's SciFi.

Gosh, didn't know there was an app. Will have to check that out. When we were kids, we used to try using the old tube radio dials (remember those? I still have our 1940's Magnivox 8"in TV/radio/turntable console in the attic.) as a sort of theremin, although we didn't know what one was. Really pissed my Mom off.

Well now I've dated myself.

I know exactly what you mean! I have ham radios, and they are variably tuned like the old AM radios. These just happen to be really new high-power AM radios, so they can get that same funky sound. That sound is called a heterodyne BTW, which is the technical term for mixing signals. In the 70s is was popular to buy receivers that were "superheterodyne" because of the way they mixed signals. The whine you heard is the mixing of two signals interfering with each other on the air.

Looks like the back of my Dad's room when he messed with CB radio's, morse code stuff & repaired TV's! I never went near the stuff or touched any of the doo-dads....very scary to a young one!

I can always remember using power tools and working on engineering in lifts so loads of different meters used.

I laugh when people try to pull a fast one on me thinking l know diddley squat .

I am not in your league though but always enjoy being able to fix stuff

That's awesome! A girl I grew up with had a father who did engine repair. She knows an amazing amount about engines and fixes up broken lawnmowers for fun. I pity the man that thinks she's clueless because she's pretty and blonde. :)

Oh yes l pitied the salesman who came to our door once trying to sell me fascias and sofits and then asked for the man in the house because women liked the finer points and fripoeries in the house.

Asked him who the hell he thought painted the fascias and soffits on my house,before proceeding to inform him the man in my house is far more interested in the fripperies than me and as l put half the windows ,doors in our house plus fitted the bathroom,kitchen ,and the built in wardrobes plus rewired half the house l think he can speak to me instead.

Also the guy who tried to sell me normal wire instead of pyro for a back boiler.

Best one still has to be when l worked next to Lloyds building in London and was helping fix the lifts in when a guy came up the stairs swearing his head off over lifts not working.
very red faced when he spotted me.

Did enjoy those days but nowadays it pays me more to operate a machine now rather than engineering now but was fun while it lasted.

My mum loves seeing me as she always gives me the diy list and those of her neighbours everytime l visit.love the look on their faces when l can fix up stuff for them.

That is outstanding.

We had an electrician come to upgrade our panel from 100A to 200A. The poor guy had no idea who he was dealing with, but he soon learned after I had him re-run all the sloppy wiring. I had him run some Cat-5 for me since the walls were open and I had to re-run it all. At least he complimented me on my work. Oy.

I work indirectly with Silicon Vally visionary and billionaire (first investor for Google) Andy Bechtolsheim. That guy is amazing beyond words. When we were having our new headquarters built, he asked for some crazy amount of power for our data centers. The city electrician told him that it wasn't possible. Andy politely showed him where his math was wrong and why it was possible. We got the power. :)

I love being out there because all the big brains make me feel like Forest Gump.

Sounds strangely like my life. My neighbors call me to fix everything from computers to autos, take care of their home fix-it problems, or field questions on pet health and welfare, etc. No subject is off topic apparently as I've gotten some very strange questions at times.

In fact, they made me a T-shirt one Christmas that says 1-800-ASK JANE. hahahaha. I wear it on housecalls. Can't blame them as I have way more tools than the average man (4 generations worth - even have my great granddaddy's woodworking tools and chest that he loaded on a wagon and hauled around the countryside in the 1800's). And grew up in a construction family where building/repairing stuff was the norm. No sisters or girl playmates sadly, just boys all around. Oh, and I work for food (or free), so the price is right. Jack of all trades (or is that Jill), master of none.

I'm getting to the age where I can't do the heavy stuff, but I'll always prefer making and building things myself instead of hiring it out whenever possible.
