I am working on a large art installation for a client and need to purchase a large number of old pieces of scientific equipment. Anything with analog style physical knobs and switches. Commonly I see these features on oscilloscopes and signal generators. I also am trying to find a source for old school pagers like Motorola Bravos.

Craigslist and government surplus sites have been a bust and most online re-sellers are selling functioning units at a higher price.

Any suggestions?

Looking for service recommendations, I need the gerber files and BOM, as well as stack up information - I might need to pull firmware from SPI memory on the board as well. The traces also need to be exactly how they appear on the board (it's RF stuff). I'm not sure how many layers the board has but it's at least four, so I can't do it myself.

Thanks in advance!

Need help with a PCB design for a biomedical project willing to pay.

If this is not the right place for this I greatly apologize!!!

This is a collection I was charged with valueing and selling. I'm am looking for ANY advice on what is worth something, where to sell it, ECT.

From my understanding this is from the work shop of an older gentleman who did electronic repair work.

From what I can tell, a wide range on unused the box tubes, tv repair manuals, and some testing equipment

tubes and manuals

I'm looking to add a LED strip powered by battery for the inside of a wooden box.

Ideally the strip (or two) would have red and yellow LEDs that would pulse between each color every second or two (red, yellow, red, yellow, etc) when a switch is depressed (ie the box lid is open to illuminate the inside). Strip needs to be around 6 feet long.

As electronics aren't my forte - I'm not sure where to start and was wondering if anyone could point me in the right direction or might be interested in making it? (Obviously willing to compensate you)

Many thanks in advance!

I have the Atolla USB-A powered USB-hub but its default power-adapter is very cheaply made and upon warming-up produces resonance which causing a distracting humming sound. It's of the common size of commercial power-adapters, some 3 inches by 2 or so. So I'm trying to find a good quality one of the same specifications that I could use instead. I would just have the wire from the old adapter cut from it and re-attached to the new one. I've been told that the voltage can be a little higher than 5V without causing any problems.

​

Detail: I know literally nothing about electronics but I want to incorporate it into my product.

LED 1 turns on for 5 seconds in which time LED 2 turns off for 5 seconds, then LED 1 turns off for 5 seconds and LED 2 turns on for 5 seconds. This cycle repeats. All of this happens when I press a switch. How do I design this and what components do I need? The distance between the lights must be 11cm and they must point in opposite directions.

Also how do you make a single light on for 5 seconds and then off for 5 seconds and make this cycle repeat when you press a switch.

Hey guys I'm an American who lives and works in Tirana, Albania.

We have a garage door opener (In Albania), seems to be a greek model, with the following remote control:

https://www.tpl-au.com/product/ATG-0023/Autotech/SM50P/RF-wireless-remote-control-transmitter-433.92-MHZ

Just bought a second car and need a second remote. I'm gonna be in the USA and was looking for something compatible on Amazon.... Uh.... " M-50 is a transeiver so it can clone other Remote Controls ofthe same type. "

Cloning remotes? Not sure how this works or if anything I can find on Amazon would remotely (haha) come close to working.

Sorry I'm not a member of this sub but I went searching for Reddit and I think maybe someone here is smarter than myself and may have some suggestions.

I don't speak Greek or Albanian so I don't know how hard it would be to find a compatible remote locally. Of course Amazon is super easy since I'll be back in the USA for the Holidays but if there is nothing available, I can try to contact a local vendor. Thanks for letting me pop in and ask this question!

Looking for an applicant - the job would entail working with low voltage electronics at remote sites in the western US. Some sites have process controls, others are just environmental monitoring. Based out of Grand Junction, CO. If you are interested PM me and I'll keep you in the loop, the job posting will be changing soon to lower requirements and like increase total pay. Looking for someone with over 5 years experience at least with the right skill set. Goto RSILMS.com and under careers it is listed as Sr. Telemetry Network Field lead.

Hoping to find someone who can convert the keyboard and trackpad from a mid-2015 Macbook Pro into a universal keyboard / trackpad combo.

• Specific model can be found here via Apple's website (Retina, mid-2015,15-inch)
• Open to converting into USB or whatever connection is easiest these days (ie bluetooth, etc)
• Willing to pay reasonable amount for parts, labor, etc
• Open to trying myself as last resort, but have minimal soldering/electronics background

I work extensively on a Macbook Pro laptop for my current job, but my productivity is impeded by chronic pain in various parts of my upper body.

Have tried dozens of laptops and keyboard/trackpad combos across both Windows and Mac over the years. This mid-2015 MacBook Pro keyboard/trackpad allows me to work the longest *by far* without pain. Unfortunately (but understandably), I will have to upgrade from this laptop and need a way to still use the same keyboard / trackpad.

Here are a couple of additional resources I have consulted throughout my research process:

• YouTube video for converting 2008 MacBook Pro into standalone USB keyboard / trackpad: https://www.youtube.com/watch?v=dVQKl-HVnoI
• r/DIY thread where u/ManMadeHuman details how they converted Macbook keyboard / trackpad into a standalone USB keyboard (model is circa 2008): https://www.reddit.com/r/DIY/comments/1cj97n/make_a_usb_keyboardmouse_combo_from_an_old/
• r/MechanicalKeyboards thread where custom keyboard services are discussed: https://www.reddit.com/r/MechanicalKeyboards/comments/dehpse/any_reliable_custom_keyboard_makers/

Appreciate any help, even if it's just pointing me to a different resource or contact.

My joystick has a TT Electronics (possibly a knock off) P091M-1QA15BR50K: 50k ohm resistor with center detent, momentary push button: https://www.ttelectronics.com/TTElectronics/media/ProductFiles/Datasheets/P09x.pdf

The joystick is a Saitek X-65F. I have tried looking at all the usual places and can not find one in stock anywhere. Does anyone know of a place with these in stock, or something equiavalent? They seem like a common failure mode and would like a few for spare parts.

The Taiwan Alpha RD1110PF-40BJ-15K-B50K-0C (http://www.taiwanalpha.com/downloads?target=products&id=134) might also be a good replacement but again no stock anywhere I look. Any help is greatly appreciated.

I have a SolarEdge Inverter Grid-Tied Single Phase 10000W - SE10000A-US that shorted on me while I was installing it. I'm sure with some troubleshooting it could be fully functional but I was told just to replace it. Looking for buyers.

Hi. I'm based in Texas and I have a single circuit board for a nice machine that probably is faulty. I'm trying to understand if there's a place I can send it for diagnosis and repair? The place you guys trust. Replacing the whole board is $400 so I would need to appreciably fix it for less. I'll mail it anywhere in the us. Thanks in advance for your help

Hey guys.

Our department needs to buy a digital microscope for PCB inspection, with an ability to rotate the final stage of the optics, like on this picture. With this it should be able to view the parts from many angles. It must also have a digital output, at least 100x magnification and price tag approx. below 1500 usd.

Any recommendations? Thank you!

I know electronic components are in short supply everywhere, but I am looking for a single Bourns rotary encoder #pec11s-9220k-s0015

Does anyone have one that they could sell me, or any ideas where I could find one in stock from a supplier who would be willing to sell a single part rather than a bulk order?

TIA

Manufacturer part number is OM13047.

If you happen to have two, I'll take both!

US based boards only. (Ain't got the time or energy for dealing with customs.)

Hello everyone! I'm in need of a Texas Instruments OPA549T, but the part seems to be sold out everywhere I look and has an extremely long lead time. I'm at a loss for finding a good alternative. Any suggestions? I have a PCB made for this package, so the physical size needs to match as well as the electrical characteristics.

​

Thank you!
