Would you recommend buying this and running it in eco mode if I have air cooler. Or buying one of the lower tdp zen 5 chips. Which have a lower initial purchase price too. Im going to be running this on a full server that runs 24/7 but also as a main desktop machine for intensive tasks. Previous cpu was ryzen 5 1600 bought in 2017.

For me it's determined by the expensive electricity we have here in the UK. I run an N100 as my only 24/7 box. It runs an SSD NAS and VMWare Workstation with Home Assistant in a VM, and idles at about 8W. I also have a couple of dual socket rack mounted servers with bags of RAM and SSD arrays for system and end to end testing, but they're only turned on when I need them, or in the winter when it's cold. The 9950x machine is my daily driver though. When it had the 7950x in it, it idled at about 100W: I'm not keen about having that on 24/7 with my expensive electricity! I'm not sure what the idle draw is with the 9950x, I haven't measured it yet, but I'd imagine it's about the same. There is no doubt you'd see a massive uplift from the Ryzen 5 1600.

Interesting. So that little potted stick is an inverter. I always wondered what those were. In addition to the PR100, I had an SR4190R that carried me through tech school. It had a killer feature - I called it "exponent bumping" that I have never found in a non-Commodore calculator. Basically, if you have an answer in nano-somethings and you really wanted micro-somethings, you just hit a key until the exponent shows -6...the mantissa will adjust to suit. Being so fond of that, I still have a working 70's Commodore on my desk - an SR5190R. And a couple SR-1800's. Not as fancy as the SR5190R, but they have gorgeous green fluorescent displays.

I didn't trust Chinese Smart plugs they always faulty. My 4 WOOX WIFI Smart plug from last year, 2 plugs went failed stuck permanent power on & 1 plug failed won't turn on & 1 worked fine but sometime come back stuck permanent power on. I go back old timer/schedule worked fine & remote switches plugs non-smart plug worked fine 🤷 Most Chinese are not good electronic skilled. Need more made in USA or Euro or UK products.

This is exactly what I wanted to do. I purchased a PIC16F1939 to drive 4 static large 7 segment LCDs. I did not know about multiplexing consuming more power. So which one uses less power: Using 2 Common pins to drive 4 displays in 2x2 groups or using all 4 Common pins to drive all displays with same segment pins? I unfortunately can not get the LF variant of PICs locally so I will see what I can do with this one. I guess adding 2 more 7 segment displays to show seconds is kind of pointless and will only increase power usage. I will just use the dots of the displays to show 1/4 of an minute. Yesterday I wrote code to use timer1 with 32768Hz quartz crystal to count up to 9 on a single 7 segment LCD and will soon try adding other segments. What I want to do after making this is to use PIC16F1936 to drive a combination of very small 3 digit and 2 digit 7 segment LCDs to make a wristwatch. I also have a 4 segment watch LCD with the “:” but it is 3cm long so bit too big for a wristwatch. After making my LCD purchase I realised that they sell a 6 segment 2.2cm long one which is the perfect size for a wrist watch.

I connected the rtc according to the data sheet, but it's using 45uA instead of 45nA at 1.8V. Any idea why this might be? The clock works perfectly, but it's drawing way too much power. BTW, I'm using the evaluation board version of the RTC, which already has the SLA and SDA with the 10k resistors. Feel stuck at the moment. Vdd is 1.8V straight from power supply. When I connect it via 2x 10k res, the clock starts at 00:00, but counts one minute every 2 seconds. Microcontroller draw is 380nA and each segment around 45nA. Any help would be appreciated!!

Did you clean the board(s) properly in an ultrasonic cleaner? Where are you measuring the current? 45uA is about what you might expect from a weak pullup being pulled low. I have no idea how you've wired up the demo board.

Yesterday, I just repaired a Kasa Smart Plug. In looking at this video, I'm quite surprised how similar the electronics look. Not 100% the same, but very close. I have a whole bunch of these Nasa plugs and they have been flawless. I even have some in our garage which is about 150' from the house and router. Yet, they connect and stay connected to WiFi. So with this one plug, it went bad due to my not putting attention onto what I was doing. I had this outside to control the back yard lights, turn on at dusk, off at 10PM then on again at 5:30 am and off at dawn. I placed this under the rear patio roof and covered it with plastic to protect from the weather. Well I didn't do such a good job on that! LOL We had a lot of rain over the last couple of weeks and I found that this outlet stopped working. I brought it up to the lab to find that there had been the Magic Smoke generator was activated. LOL I had to use rotary tool with a fine-point tip to dig out and clean up the carbon where it turned the PCB. I did get lucky, because with all that shorting going on, the only component that failed was the fuseable 10 Ohm, 2W resistor. This was one of the tightest tolerances I have ever seen. It was a 0.25 % tolerance! LOL No way I could find any around here and no way I would order from China... so I found some fuseable resistors, 10 ohm, 2W but 5%. I just measured some to find one that was bang on 10 ohms. It worked perfectly. I'll say, these Kasa products are really good. I have... well.. HAD... some other outlets by a different company that just never worked right. They were bitchy to set up and constantly lost connection. Now, they won't even connect and many people are complaining. No biggy for me, however, because I'll just strip them for the relays. LOL

@nezbrun8727 ай бұрын
Yes, but I've never been successful with home-made boards because I don't have the facilities for a solder mask, which is essential for BGA or WLCSP. Don't ask me how I know! With an appropriate commercially fab'd breakout boards and PCBs (with solder mask!) it's not too hard. I place the BGA/WLCSP first, tinning the pads, removing excess solder with wick, then add flux, place the part & apply hot air. This has to be done before all the other parts are placed so I can inspect the balls by gazing through the gap between the package & the board, with the board held vertically. I use a stereoscopic zoom microscope for this. Then I use a DMM on diode to check for protection diode connectivity to supply lines. I use an old HP 34401A for this, which offers fast audible feedback. I've yet to witness a better DMM for board checking TBH. They still hold their value on the second hand market for good reason. The problem with this method is that it means you can't really use a stencil, but to be honest for a one-off prototype, manually placing a couple of hundred parts can be quite therapeutic especially if you have a decent soldering setup, including soldering tweezers & hot air as well as a couple of irons with appropriate bits loaded. Commercial assemblers perform inspection using a microscope with a tiny mirror at 45 degrees to look edge on into the package/board gap. That way all parts can be placed while still being able to perform inspection.
@NicksStuff7 ай бұрын
@@nezbrun872 For the continuity test, I've seen a guy hack his cheap DMM to produce a different tone depending on the value of the resistance. I thought that was brilliant and might indicate you there's a cold joint for instance if the pins go bip-bip-bip-booooop-bip, for instance

Nice job and thanks for sharing that Omron ref! The relay is far from being the tallest thing on that board, so realistically you don't need to match the pinout, you could rewire it........and maybe use a solid state relay in its place? I find the audible click of a relay sounds quite archaic on a supposedly premium electric gadget in 2023
@nezbrun8728 ай бұрын
I did look into solid state relays, or rolling my own triac circuit. The problems with these are cost (particlarly for the solid state relay solution) and heat dissipation. The heat issue means switching a decent current will take up space. Now I know why they didn't use a solid state relay to begin with! It you're willing to use a different enclosure to deal with the heat, a solid state relay or triac solution makes a lot of sense. So I took the path of least resistance (pun not intended) and picked a compatible relay.

If all you do is quarter or half hour increments, yes, do it in your head, it's easy. If you're a pilot, where each flight has several times, all logged down to the minute, such as calculating in-the-air flying as well as blocks on/blocks off times & durations, and cumulative durations separated for single/multi engine, day/night, in command/P2, IFR and simulator, it's not the kind of thing I do in my head. But good for you.

@@nezbrun872 That's a good point, and also if you're a pilot then you do this a LOT, and lives may depend on you doing it right. We're human, and eventually we make mistakes, so any sort of automated assistance that reduces that error rate is of high value. I wouldn't feel at all comfortable claiming that my *error rate* doing it in my head would be as low as doing it with a device assisting me.
