I'm going to be fixing this Pioneer CLD-1750 in a few weeks (my next spare time slot). Fault is it doesn't read discs. Laser moves, focuses, moves in, focuses again, then gives up. No spindle movement. Anyone have any ideas? I'm hoping it's not laser failure - but it glows red on camera.
I've tried cleaning the laser lens.

Ponderous pachyderms, which #soldering ("sol-der", not "sod-der"🤣) station (through-hole or surface-mount) brand do you keep on your #electronics workbench?
Ponderous pachyderms, which digital #oscilloscope brand do you keep on your #electronics workbench?
Ponderous pachyderms, which digital #multimeter #DMM brand do you keep on your #electronics workbench?
Damn it, I hoped it would not come to this, but I guess I'll have to actually solder those pins onto the test pads of the #PocketViewer. I can use the multi tack glue for temporary support and the glue gun to stop the pin from moving, but that still leaves a small gap between the test pad and the pin, so I have to flow a little bit of solder on there. Tested it with one pin, seems to work fine, but idk how I'll manage the other 8 without any of them shorting.

Would fitting a cheap mobile phone which, when called, triggers a solenoid switch to create a dead short across the lithium battery resulting in a huge fireball be too extreme as an anti theft measure?

3 x AA Batteries == 4.5v
4 x AA batteries through LDO -> 3.3v 8 months still going.
3 x AA batteries through same LDO ->3.3v died at 6 months
is it just because even though they're in series there's one more "cell's worth of mAh" available? i'm expecting more wastage from the 4 cells.
The device is on for <2 seconds, then hibernates.

Programming and testing went okish. There were three issues. BP checks VUSB, old test PC with out of spec USB ports (Vusb<4.75volts) caused fails. Small race condition during self test caused a few over current alert prompts (flashing inverted screen colors), simple code bug.
Egads. I misread this as "HeathKit apps" and thought, *that's* old-school.
I'm currently talking to a supplier to make neon 22 AWG solid hookup wire :3 Anybody interested?
This is the selection I'm working with so far. I'm thinking of leaving out 901C. If you had to pick between 901C and 929C, which would stay? I'm thinking of keeping 929C because jazz cup. Or maybe they both are nice together.

Baby's first pcbs are here*, straight from China! It's insane how cheap those have gotten these days.
Not very ambitious perhaps, but at least it will be useful. Couldn't find ones exactly like these ready to buy anywhere (not too wide so as not to hog breadboard space, and at the same time able to accomodate both narrow and wide soic chips).

Hey, everybody! We're in the feedback phase. Some more devices have gone to Armenia, USA and Germany.
A few devices have been sent to Mestastic developers. Made some non-critical updates to the interface and functions on the git. We are moving, perhaps slowly, but surely. The basis is still the protocol.

So I have an Siglent SDS1104X-E, which is perfectly adequate for my use case and has been for several years
But I've been getting by with a cheap single channel 30x5 desktop PSU, handheld multimeters, and no function generator, and I'm fed up.
My budget is (or, yk, will be) about a grand, maybe a tiny bit more if I really need to push it.
What lab power supply, DMM, and function gen should I buy? Is it worth it to go with the Siglent options for integration reasons?
Eventually it's going to have to go into an enclosure...

A new #introduction
My name is Spencer and I decided to join Mastodon because I like the idea behind the #fediverse and a more decentralized system. I also think the alternatives are becoming crappier by the day ...
What social media I've done involves my #hobbies of #gardening and building a #scalemodel when I have time.
My other interests are #reading #sciencefiction and #electronics
I have a background in #Science ( #Physics ) as well.
I hope to make some new connections here! 🙂 🖖
Inspired by both Ben Eater's site and by @blogmywiki's own attempts, I've been meaning for ages to have a go at creating a simple 6502-based computer.
Today I finally had enough free time to sit and start playing. Even though it's not really doing anything yet, it's still quite thrilling to see all the LED lighting up.
The Arduino by the way is just there to help me monitor the output, it's not part of the actual system.

heading this off at the pass: no, JLCPCB's ToS do not grant them the right to reuse or sell your PCB designs. read the full text to understand the context and purposes applicable to the rights you're granting them, not just one isolated sentence, and think about the functionality of the site (e.g. generating gerber previews from your uploads, storing uploads in your account's file manager page, publishing customer reviews, etc.) and what rights must be granted to support that.
I whipped up a little box to hide the wiring in and mount the control panel on top of for the wire measuring machine. I still need to tidy up the wires but it’s much better with them out of sight.
*sigh* Replaced all the capacitors. The screen is still only giving me backlight for about a second, but now it makes really unpleasant peeping noises.
I assume the backlight converter is toast, which would be kinda bad... No idea where to get a replacement that fits. #electronics

Holy heck, I found two mystery buttons on my #PocketViewer. There are 5 switches clearly labeled on the PCB, but two of them only have holes on the rear of the case, but there is no rubber dome or switch in there. The switch's hole is even covered with electric tape.
Any #Casio engineers wanna tell me what they could be?
One is labeled as "P" on the rear and has a similar hole as the reset button, the other looks like a slide switch.

Due to Apple's #iPhone #connector change, we have decided to review our collection of #wires, small peripherals, and other items surrounding our #electronics.
Much pictured here is being organized. We determined that we have enough:
* Apple extension cables
* USB-C to #USBC cables
* USB-A/USB-C to lightning
* #cable management velcro
Not pictured: my CAT-5 cables, HDMI, coax, etc.
I’ll be consulting our city’s #eWaste department.
I’ve added a second wire guide to the wire measuring machine. I may need to find a longer board and add a tray where the cut wires can land.

Dear fellow Electronic humans. Does someone know if there is the possibility to adjust the soldermask opening for this BGA if I do not have access to the library? I adjusted the main rule and all other components have been changed, but there is an overwrite for the BGA. #electronics #altium
Hello #electronics people. I would like to improve on a couple of things like soldering and understanding building solid circuits. Also would like to know more about power consumption and making schematics of circuit design. I'm a web developer but I would like to learn more about electronics so I can build stuff with micro processors but also larger installations. There are part time HNCs and BEng courses near me. I can't find any evening courses really. What would you recommend?

A challenge for #electronics #hobby buffs:
If you look at the the #Ada program (with translations to other languages) in my pinned toots, you will see that the #entanglement of #quantum stuff is actually just the correlations of phase-diffed sinusoids randomly sampled.
So here is your challenge: make QUBIT circuits out of op-amps or 555 timers.
(I plan maybe to get to this myself, but I only dabble a bit, and my electronics bench is covered with unrelated garbage since early in the pandemic.)

Do people with a #functionalProgramming background have an easier time with #electronics / #hardware design? Thinking specifically of things like #FPGA dev.
I was listening to an Unnamed RE episode recently where the difficulty of learning an HDL was attributed to it "not being like programming", where "programming" means "writing a series of instructions that modify state".
Also worth asking if this extends to other math-y areas.
Any #electronic experts have recommendations for a #multimeter?
I need to figure out which of a loom of wires coming out of my car's ECU is supposed to be running to the fuel pump relay which a previous owner deleted.
I've heard that "clamp" style meters can measure wires without probing them. Will that work if the wire I'm looking for has been disconnected?
Any other features I should look for?

Just finished a DIY project of mine that has blocked my workbench for over a year: A custom Blender logo "neon" sign.
Has a 3d printed frame. Atmega328P based microcontroller to pwm 1.5 m of neon LED tube, plus a buck converter and 24v power supply.
Huge thanks goes to @sybren for designing a MOSFET driver PCB for me because my original circuit tended to explode ever so slightly 😂 #blender #b3d #diy #electronics
Any #suggestions for a free/open source 2D #cad program that would do well with abstract block diagrams for #electronics? Looking for something akin to a #schematic design entry UI in #fpga IDEs but doesn't need to have any semantics. Just want to sketch modules, multiplexers, logic gates, and slash notation for buses.
I bought JST cables to solder to a LiPo and the freaking polarity of the wires was reversed and I blew my LiPo charger and gave myself a blister in the rush to not burn anything.
Off to a great start today. Note to future self:
- Always check polarity.
- Don't buy shit from Amazon.
This layout is so clever and nice :ablobcateyesflip: Small Input and output loops, and the input nodes field counteract each other. Feedback is far away. Great stuff.
Only the thermal performance of this part could be better.
First chipshots from the new microscope. No idea what this chip is, other than by Motorola and with a mask code of B61T ZC419213. Does anyone recognise the artwork next to the batwing in the first photo? I'm guessing it's a country, county/state or city. #ICRE #siliconart #electronics
Edit: thanks to everyone who pointed out that's Switzerland! The chip also has the text "Motorola EDO" and "EDO Geneva" on it, which should have been a hint XD
This is really cool: About ten years ago, a few friends and I built the first #Matelight, a very large display made from crates of glass bottles stacked up sideways, with adressable LEDs stuck into the bottles from the back. Now Hito Steyerl, a renowned artist, used a Matelight inspired by the actual one we hacked together back then at c-base as a part of one of her installations, called "Green Screen". Here's an article on the exhibition, and a photo:
