The thick book with a blue cover on the left is Tektronix's service manual, which includes detailed schematics and troubleshooting procedures.
This remarkable piece of hardware seems to be in good hands, I'm looking forward to see it work again.
I forgot to ask the model. Can anyone guess it?
I went to the Artisan's Asylum and found someone who was attempting to repair this beautiful CRT oscilloscope by Tektronix.
I did a write-up on how I use #qcad and #freecad to create visually appealing enclosures for your #electronics projects. #3dprint #diy

Now I know more than what anyone ever wanted to know about a coax cable connected to nothing. #electronics
This prototype cycle for my temperature and humidity tracker is almost complete with a new 50% slimmer case. It's been quite a journey #electronics #kicad #esp32 #micropython #blender #3dprinting
Tom’s Hardware: PCB reference books with pages made from actual USB-C powered PCBs are now available at $37 each. “An electronics, metalworking, and 3D printing enthusiast has created some Reference Circuit Books where the ‘pages’ are PCBs. Published by Bolt Industries, there are presently two volumes available, with their content produced by the aforementioned expert enthusiast and […]
Wondering what goes on inside a lever-wire connector? Here ya go!
This is a KF141V compact 0.1" vertical connector. So far, seems like a great alternative to screw terminals.
It's quite difficult to actuate the lever, which is great. It is spring-loaded, so it returns to closed position nominally - no multi-stable mechanism. #electronics #pcb
electric cats, a simple question for you: I have an electric guitar with a 5 way switch (2 dual humbuckers, 1 single coil). The 5 way switch is wired such that positions 0, 2, and 4 are neck humbucker only, single coil only, bridge humbucker only.
I swapped them out recently and those positions work 'fine' (except I think I soldered the wrong pickups to the wrong position, but hey, it's symmetrical, who cares?).
Positions 1 and 3 are a combination of a single pickup from the humbucker (split) and the middle single coil, and these are much more compressed and lower volume than the other positions. I think I fucked up the soldering and suspected I did something like swap the hot and the ground wires for each humbucker.
My question: A, without pictures or more information, does that make sense/seem plausible? B, would this be an easy to answer question if I gave more info and some pictures? C., ... what would this phenomenon even be called so that I might be able to look it up more in depth to see where I went wrong? It's like they're almost perfectly out of phase, or something; the reduction in volume and compression reminds me of destructive addition.
I wasn't able to find exact wiring diagrams for the new pickups (some inexpensive licensed duncans that are apparently duncans in name only) but the Ibanez wiring diagrams are easy enough to find. Any help or insight anyone can give would be super appreciated! It's still quite playable, as I largely just avoid positions 1 and 3 right now.
Thank you! reboosting totes appreciated

Anyone know the hex code for alpine stereos that triggers Siri on an attached phone? Pls boost? #alpine #electronics #hacking
Here's a clearer picture of what the scope displays.
This is kind of fun. Using an infrared receiver module (TSOP38238) to display the signals produced by a Blu-Ray player remote control on an oscilloscope. The signals are active-low and pulse-width modulated.
Hey folks, I am doing a presentation on a brief history of #usb at work later this week and was wondering if Mastodon had any suggestions/annecdotes/things you wished you knew earlier that might be worth including?
Now where are the dedicated charger IC's for sodium-ion cells?

I've been looking to get into PCB design a little more recently. I have a pretty solid grasp of the actual theory/design process and experience with KiCAD, but it's the actual logistics that I'm stuck on. Specifically, where is the best place to buy components?
Do you buy them in bulk? Alongside each other in the same shipment from some vendor? How do you deal with having enough of the many different types of SMD caps/resistors? I feel like getting stuff from say aliexpress in individual shipments of each component type is not very cost effective.
I found a Bose Wave CD changer in a free pile and of course it doesn't work. BUT searching for information on how to repair it brought me to this amazing channel: https://youtu.be/B7aWFQe6j8M
This man is a GEM. I don't normally like watching how-to videos (give me a write-up any day) but this guy is worth it.
Related: can anybody recommend an affordable ESR meter and a non-amazon source for electronics parts like small capacitors??
Today we're dropping a @defcon teaser AND running a Pre-Order Sale for Designing Electronics That Work – the book that answers "which capacitor should I actually buy?""instead of explaining what a capacitor is for 50 pages.
Use code PROTIPS for 30% off through 7/28, or stop by our booth at the convention for a special edition (and maybe the author's signature? who knows!)
Can anyone help me out with this? I’ve tried soldering wick, flux and extra tinning to try and get rid of it! I just want clear holes to put my switches pins through! I’ve tried both sides too #electronics #soldering
Glider antennae for the FLARM collision alert system ... where to put them?
I have three antennae to worry about: GPS, ADS-B, and FLARM A. (FLARM B is an external antenna on the bottom of the fuselage.)
They can't be too close to each other. The blue strip of aluminum taped to the nose shows the notional canopy inner surface, so there is not much height available. Fortunately, the instrument bay top cover is fiberglass is radio transparent. If I have to drill a hole to set the tallest antenna a bit lower, that's not all that terrible.
Note, for proper antenna polarization the dipoles must be vertical.
Considering all the other antennae I have (transponder and its GPS, radio, infotainment system, SSMIS download and HAM relay), I'm starting to feel like this airplane:

At least I don't need a long wire HF antenna. Or do I?
Phil's Lab published a really good video about inductors in practical designs, and as always it's very much worth a watch.
Does anyone know what to search for when I need one of these connectors?
