Hello, I am in need of a micro Bluetooth 10keypad that can be operated in my pocket with 1 hand. Any suggestions or help is great! Thank you.

I am trying to get into HW failure analysis and debugging. I can read schematics and understand electronics. But haven’t dealt with oscilloscope for last 15 years since my college. I need some one who can help me navigate through an oscilloscope, real life demo ways to read SPI, I2C, PCIe, Clocks, etc buses. and give real life assignments. I am looking for a live hands on training instead of watching YT videos.

Brand new here and a dufus when it comes to electronics. I would love to have a custom built rzr v3 that works with todays networks or at least has the outer shell/case that looks identical to the rzr, accepts a generic sim, can call, text, and the camera works. What private companies or contractors can I reach out to, and what is a ballpark cost to have this built?

To sum up: custom built phone with the basic capabilities (maybe an upgraded camera )all encased in an old motorla flip phone shell.

I have a bunch of these in pairs, not moving on EBay, if someone wants to take them in bulk, let me know.

I’m in the UK. If this is not allowed in the chat, let me know.

I am in the process of ordering custom components through a Chinese manufacturer, however they are charging 230$ for freight on something that will arrive in the size of a shoebox (which is even more than the $150 I'm paying for the components themselves). The seller told me they can cancel the freight if I have an express account and then arrange a waybill on my own. I'm new to this so I am confused and would like some guidance on how I can go about doing this and the opinions of this with someone experienced with procurement from overseas. Thanks for any and all responses!

I have some control boards from a Pick&Place SMT machine. These boards are worth something but selling them is difficult. Tried general ecommerce website without success, tried specific website too, with same result.

Where can these type of boards be sold? Thanks!

I'm buying almost any type of electronic components, test equipment, and tools.

IC chips, sockets, connectors, switches, relays, etc. I'm not too interested in things like computers, phones, or TVs, rather the parts that go into making them.

I'll buy new or used, old and obsolete, items found during cleanouts, even things picked out of dumpsters.

I'll buy small or large quantities, from individuals or compaies.

I'll come to you, pay in cash, and haul it away.

I train bird dogs. One of the tools we use is a bird launcher I have a unique idea for one that involves RFID.

Basically, I want to build an add-on to the launcher. Ideally, it would be a UHF RF-ID tag that could clipped onto a dog collar and a remote solenoid added to the launcher. When the dog gets within 10-15 feet of the launcher it would automatically release the bird.

I have experience in building circuits and repair, but the actual design is not in my wheelhouse.

What would you charge to design this circuit? Ideally the remote circuit and battery, circuitry would need to fit into a 5X2X1.5-inch box

I would prefer to work with someone within a drivable distance of Youngstown say 2-4 hours.

If this isn't the right sub please direct me to one more appropriate.

Hey everyone!

I’ve been trying to find a manufacturer for an electronic device through Alibaba for several months, but I haven’t had any luck reaching a reasonable agreement. The main issue is that most manufacturers require large orders just to create a prototype, which isn’t feasible for me since I’m still in the development phase.

The device I want to manufacture is a waterproof bracelet with BLE5 that can connect with others and emit alerts based on set distances. It’s a relatively simple design; I already have a prototype on a breadboard and all the schematics ready, but it’s been challenging to find a lab or manufacturer willing to produce it at a reasonable cost and without excessive bureaucracy.

That’s why I’m reaching out to the community to ask for recommendations for factories, labs, or even independent developers who have experience creating electronic prototypes at a reasonable price. Any advice or contacts you can share would be greatly appreciated.

Thanks in advance! 🙏

Hello, I am looking for a budget variable AC power supply for a test lab. I work for a small company and we are limited in resources, so expensive power supplies are very unlikely to be approved.

The requirements for our lab are to supply up to 277V AC with a minimum of 150VA rating. We only have access to 120VAC input through our outlets, so 120VAC supply would be best for us. Our boss prefers American made products, if at all possible. Open to all suggestions within a reasonable price range to propose accordingly. Thanks in advance

I have an Apple HiFi that I'd like to update with tweeters, a rechargeable battery pack, and bluetooth connectivity.

Others have attempted / completed similar mods to this: *Tweeter Mod *LiPo Battery Mod *Airplay Mod

I'm interested to commission someone to complete these modifications for me, with the rechargeable battery pack being most desired, Bluetooth connectivity second, and tweeters third. Modifying the 30 pin dock to USB-C would also be a bonus.

The goal would be to retain to the external appearance of the unit while improving the audio quality and usability.

I'm located on the east coast of the United States.

If this is something you'd be willing and able to complete, please reach with a rough quote, including pricing, timing, and additional information required (e.g., desired battery capacity) to finalize the quote.

Thanks.

Where can I sell this stuff? Siglent SVA1075X - Siglent SDG6052X - Teledyne Lecroy Wavesurfer HD4096 oscilloscope WS4104HD

Im trying ebay and facebook but need gone. I know they're worth a lot and people messsge me knowing that but offer far below its value. Plus I dont want to lose thousands in ebay fees on top of taking a lower amount.

Electonics manufacturers always have dumpsters full of things that i could sell.

I used to take home 250++ pounds a week from Xerox Webster NY factory.

I now buy surplus electronics throuhht NY .... direct from companies or from workers whp fish it out of dumpsters.

The measurement is done with the mcu adcs.

How much would it cost to have someone design it?

Edit: only the cirtuit and pcb design, not the software.

Throughout the school year, we have worked on proposing a US-based PCB manufacturer that offers fast deliveries through advanced manufacturing techniques and automation. To validate our project, we need to confirm if people could benefit from this service.

The form is designed to take only a few minutes. As a thank you, we would like to offer $10 for an additional interview to those who qualify.

Here is the link to the Google form: https://forms.gle/53ErPcyjkDuJBtwbA

Thank you for your time and valuable input!

I've been working on an electronics project for a while now and am at a point where I decided my hobbyist skills needed a professional engineer's help. I'm at the point now where I'm moving from off-the-shelf TH components to SMD. I have an engineer who used to be a co-worker and we get along well. I had spoken to him about consulting. After an NDA and a long conversation about the project, the topic of payment came up. I had considered royalty or some form of payment like that a while ago, but for some reason has a feeling he wouldn't be interested in that. However, after seeing the project, and me being open about not having a large amount of money to give, meaning I would be doing the board design myself and then having him check my work, and things of that nature and him being more of a consultant, he asked me If I'd considered a royalty type pay scheme, and more direct assistance from him. Frankly, I was ecstatic, I'm a software guy, and for the product, it is going to take real polish on the software side to make it a success. I'd rather be focusing my efforts there anyway.

I'm looking for advice on what is a fair way to structure an offer to him. I know that once things are designed and working, most of the work will be me with support or software updates. Most of the value will be the software, but the hardware is important. Taking this prototype of parts and putting it all together will take a bit for him at the start for sure. He may also assist with the CAD / 3D case design so there is that to considered as well.

So he will be moving off-the-shelf components onto a single PCB, and there will be some EE around that I'm sure, and he will assumedly be helping with the Case design. Both of these things seem to be tasks that once done won't require a large amount of upkeep.

Does anyone have good thoughts on what is fair, or a way to work out what is Fair? I get along with the guy great, and as they say, rising tides raise all ships, I'd love the product to be a hit and help us both out. I want to give him a fair deal, or even a bit favorable, I just am not sure how to determine that yet. I also don't know how to calculate the risk that this project fails and he gets nothing into what is fair.

Any links to other materials on how things like this are priced would be especially helpful.

Thanks!

Mostly interested in components, new, and in large quantities. Not to interested in your old used hobby parts, unless they are out of the ordinary. ICs, semiconductors, connectors, switches, potentiometers, sockets, adapters, LCD/LED displays, sensors, tools, test equipment.

Would consider electronic assemblies, such as qty of subassemblies that went into a product your company made.

Not interested in TVs, stereos, cameras, PCs, phones ....unless they are NEW or exceptional (antiques, high performance ...?).

My interest is both as a hobby and for possible resale. I'd consider small or large quantities.

A bit leary of buying things from someone across the country who promises to ship it to me. If you want to ship it, I can pay once I receive it.

Mainly central NY, would consider longer drives if it's worth my time.

I'm looking for 8051 microcontrollers in a through hole / DIP package. I'm only interested in 16 pin packages or less ( 16, 14, 12, 10, 8, 6? ).

Not 18, 20, .......

Would want new, and qty of ~10+++.

My dad is a computer engineer and he had some spare pressure sensors that he told me i could sell, they are the spab-b2r-g18-pb-k1 and the spab-b2r-r18-pb-k1, and i couldn't find a steady price for any of them. they are ofc not brand new and only the r18 has original packaging. does anyone know what i can sell them for?

Was trying to fix one device and got in to issue where 6 pin micro IC working as low voltage converter,so input is 12V on pin 3 and there is nothing at any other pin. iC marking is 35-T3T. Circuit around it contains one inductor and a few resistors. Whole device is fully dead. And Voltage injection does not show any short circuit. I am electronic repair expert with almost 40 years experience. But still facing a problems with such elements. Device is video surveillance central with 16 analog cameras , vga & hdmi output, 2xUSB 2.0 , and 2X SATA connectors for 3.5 inch HDDs. My question is if someone can say what is problematic part and what could ve replacement part. Thank you in advance
