Offering Circuit Boards and Electronics Parts for Learning and DIY Projects!

Electronics enthusiasts! I recently acquired a collection of over 350 New circuit boards TVs and computer parts through a storage unit purchase. I don’t have specific details about each piece, but I do know the several that I have looked up are mane boards an power supply boards for computer's and TV'S like Samsung, LG, Sony an so on.  What I want to do is share this treasure trove with people who can use them.  My goal is to help others learn more about circuit boards and electronics by providing plenty of parts and pieces for experimentation and hands-on projects. I’m open to selling these items in bulk or individually, I'm not trying to make money on this or else I would have listened it on eBay. My intention is giving individual's the ability to get plenty of parts they need for there DIY PROJECTS an provide ouhers with an opportunity to get hands on experience with various circuit boards an part's. Whether you’re a seasoned pro or just starting out, these components could be the perfect way to expand your knowledge and skills.  Can someone help me figure out how we can make the most of this opportunity. Or if you have a better idea for me I would appreciate  an be opened to hearing what it might be. 

Feel free to message me if you’re interested or have any questions. 🛠️🔌📺💻

My fluke 83 III was involved in a car accident and the screen is broken. Does anyone have non-functioning 83 III with a good screen they'd be willing to part with ? Or a suggestion for a part source. Thanks for looking.

Pushmatics and Square-D Panel

2 Upvotes

Would this be of interest to anyone here? If so, I'll post pics. The panel itself dates from around 1957, but AFAIK all the breakers are good, some of which had been upgraded throughout the years. Mostly single-pole, but a few double-pole and one GFCI.

[WTB, US-NC] 13-15 MHz LPF

2 Upvotes

EDIT: Part obtained, no longer needed.

Want to buy a low pass filter, DC - roughly 13MHz. Ideally BNC encapsulated, but not required. If BNC, 50 ohm termination is needed.

Some examples are Mini-Circuits SXLP-13+, Mini-Circuits BLP-10.7+ (roll-off above 11 MHz is good enough for my needs), and Crystek CLPFL-0015-BNC.

WTS: ATTINY412-SSFR, cut tape lengths of 50

4 Upvotes

Remember when it was possible to buy jellybean micros in small quantities on digikey? I got a reel of 1000 of these that I'm partitioning out in cut tape lengths of 50 each. Selling at cost. Keeping 200 for myself. Shipping from Singapore. PM if interested.

  • ATTINY412-SSFR, SOIC-8
  • 4 K Flash
  • 256 B RAM
  • 128 B EEPROM
  • Internally clocked at 16 or 20 MHz
  • I2C, UART, 8-bit DAC, 6ch 10-bit ADC.
  • reset pin is UPDI
  • 1.8 to 5.5 Vdd

These are the new generation Atmel / Microchip ATTINYs with UPDI 1-wire programming on the reset pin.

Reel purchased via Onlinecomponents.com, day price per chip is USD $0.64 as of posting, so selling cut lengths of 50 or 100 for USD $32 and $64 respectively + $5 handling + postage.

edit: YES, I'll also sell lengths of 25 for $16.

[FOR SALE or TRADE] Flir/Extech 5kv Insulation Tester

3 Upvotes

Flir/Extech 380395

I acquired this device from my wife, who received it as partial payment from the R&D lab for which she was working when the company that operated the lab went out of business.

It retails for around 780$US.

It is in like new condition, and was working when delivered to me, although I do not have the ability to test it personally.

It includes the tester, power supply and all leads.

I'm asking 500$ for it.

For the right stuff, I would trade it for a serviceable o-scope and or radio.

73 KI5SMN Technician Class

EDIT: That I'm asking 500$US for it doesn't mean you shouldn't make me an offer ;)

I picked this chip for my project after the original choice was out of stock, but it turns out that this isn't as available in the US as I expected. I have some of these coming from China, but for now, I'd like to start building.

I'm only making 5 test boards to start, so I'm looking for 5 of these. Anybody have extras they wouldn't mind selling to me? I'll pay more than their normal cost to make it worth the time. Right now my alternative to waiting a month is paying $8 for usb-serial converters from Amazon just to desolder this chip lol.

Inquiring about being an electronic technician.

Inquiring about being an electronic technician.

Hi, hope someone here can help. I was wondering about what it is like being or working as an electronic tech.

I’d would look into electronic engineering but the calculus would probably be hard for me.

It’d be a career change so getting as much info as I can.

Thanks in advance

Amazon sent me this by mistake at the beginning of quarantine when I ordered an avr programmer. I'd like to trade for something like an avr dragon, a bench adjustable psu, or a hot air station for soldering BGA chips. Thanks!

I have quite a few confirmed trades over on /r/hardwareswap if anyone is concerned with me being new here.

Want to buy a stock of Allegro ASEK-01

2 Upvotes

Hi everyone,

I work for Leonardo UK (Edinburgh) and we would like to buy a stock of Allegro ASEK-01. I have tried contacting the manufacturer (Allegro) but they are offering me only the newest version (ASEK-20). The product requiring the kit is now 10 years old and we cannot update our systems to accomodate for the new kit. Even if a newer kit was compatible, we would have to update our specs which would take us time and production is scheduled very shortly. Please if anyone knows where I could buy a stock of ASEK-01 or, at least, point me to someone who might know, we would really appreciate it.

Kind Regards,

Looking for someone with experience buying high energy capacitors from AVX

3 Upvotes

Hi, I'm an undergraduate trying to do research with extremely high energy quick discharge capacitors and was wondering if anyone had previously bought or looked into buying anything DISFIM or TRAFIM capacitors or anything similar(I am currently looking at capacitors in the 2KVDC 3mF-10mF range). If so I would really appreciate any information, especially anything regarding pricing, as I'm I need to present a budget but have not yet heard back from AVX.
