Fluke 83III DVM help

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

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

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

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

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 ;)

[WTB, US-CA] ch350c

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

[US-MI] [H] Microchip MPLAB ICD4 [W] AVR Debugger, Power Supply, or Hot Air Station

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

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

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.

High energy quick discharge capacitors

Looking for some 7000VDC-30000VDC capacitors with a minimum stored energy of at least 10kJ. Does anyone have any capacitors like these, or know where I might be able to purchase them, hopefully, ones that weigh less than 100lb.

[WTS/T] Quantity of sealed new Leviton eXtreme 6 + patch cords, 8 ft, Cat6 - for...

... purchase of an $129 (free shipping) HF antenna for me, 1:1 trade. Or $3/each, shipping extra. Just made it to Amateur Extra last month.

Prefer trade to be face-to-face in San Diego, CA, so...

A) None of your money is wasted on shipping/you get the maximum amount of patch cords for $129 (43)

B) I can unseal the antenna's shipping box in front of you

C) There's no possibility of either of us getting nothing with the "you send first" game

D) If the deal falls through, the currently-on-sale antenna should go back up to its regular price at the end of May, so you could sell it new at a profit or enjoy having been able to buy it at a discount yourself if you're a ham too.

Please text only 619-393-2253.

In need of an oscilloscope for studies

Hello Reddit,

I'm currently studying computer engineering, and have found myself in need of an oscilloscope. I am not quite sure what I am looking for, but i thought I'd ask here. I can't afford to spend much more than $50, so I am assuming that puts me in the vintage analog oscilloscope territory. l look forward to hearing some suggestions!

PS: If anyone would be willing to part with one for my studies, please let me know! I'd be incredibly appreciative. If anyone has one that lives nearby, I'm located in Central California.
