Lenovo, IBM, DELL and HPE, High end Enterprise equipment is a big part of this channel.
MyPlayHouse channel, will show, what i am working on. Often this is IT :-) but also the house: heating, insulation, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
I bought My PlayHouse, from my grandparents in 2005. This is a 1913 old house in the countryside . A house on 168 M² / 1808.3ft² and full, of half-finished projects. But now it also has a Datacenter, full of servers, Storages and Network. On a daily basis I live and work, as an IT Infrastructure Manager in Denmark's second largest city, Aarhus.

I too plan to run one of these from the lithium battery in my camper rather than invert the battery power to AC and then have the brick convert it back to DC. Thank you for the proof of concept.
This is interesting and enlightening information. I want to use a small form factor PC for local AI. Local AI likes to have a GPU for the AI to use for processing.
Morten - if you are thinking about a tractor for your Portuguese Playhouse, reach out to Ryobi to see if they’ll build you an electric one… Boy, that’d be a lot of batteries… 🤣
They do have good stuff : www.ryobitools.com/products/details/46396041029 But when using that kind of money,, it would be cool if it did more then cut grass.. :-)
"10 in the afternoon?" "Morning." 😅 St. Morten, it was so nice to have Elaine accompany you on your rounds to meet some of other CP RU-vidrs. What a fun day❣ You're very kind and thoughtful.
I had been up for hours,, out strimming and all sort of stuff :-) It was late for me :-) It was a lovely day out with Elaine,, visiting others, I did really enjoy it,, hang out and chat...
If you want to make changes to your house over there, lets say make the house a little bigger or something, is that an easy thing to do there or is it like here in Sweden (and I think Denmark also), paperwork up to your ears ?
Much the same thing in Portugal,, a lot cheaper but a lot slower,,, and sometimes it is not worth it to follow the rules,, heard of instese where it would take months to sort out the permissions,, and the fine was €6
Thank You,, Yes often a smaller unit will do quite a bit,, and if I mounted the solar panels to the unit while using it,, it will last a lot longer,, even with just 299WH of batteries.
Is the Tiny Lenovo powered by its own barrel plug power cord, and the HBA powered by its own ATX PSU? Is there no problem using 2 different power sources like this?
Thank you for sharing. May I make one suggestion to you? Check the specs of the two output mosfets on the new board and compare them with the originals. They should have the same output current rating. You might want to replace the smaller heatsink on the new board with the larger one on the older board. Typically cells in parallel such as the 5 ah board will in fact output higher currents and generate more heat through the mosfets. It's an unusual design with Ryobi as most other tool batteries will not pass the output through a semiconductor, rather directly from the 20v and 0 v points on the multi cell array.
@@MyPlayHouse May I offer a simple suggestion then, the output mosfets on the original board are most likely IRF1401Zs , the devices on the new replacement board are likely a MXP4002AT's and the two are for all practical purposed in this particular circuit interchangeable. The difference is the smaller heatsink on the new board. Simply exchange the tow heatsinks so you end up with the larger on on the new board. It's easy to do, no soldering necessary, just carefully remove it by taking the two screws off the 220 semiconductors and the two holding it to the board. Be careful not to let the screwdriver touch any thing else except the screws. Replace with the larger one using white thermal conductive glue. The mosfets now enjoy better thermal conditions.
The bird might've been hunting along the outdide of your window pane for bugs, especially if there might be spiders webs in the corners or along the edges of the glass?
All of my tools are craftsman 19.2. I bought 4 used lithium batteries. Only 1 held a charge. Using various packs and brands from the Lowes recycle bin I was able to repair the cells in 2 others. 1 had a board problem. After pouring through the net I found that some Ryobi use the same boards, just have to get t1 and t2 correct. I was able to use a Ryobi board to fix the remaining pack. Board was totally different and I had to flip the batteries around but it still worked.
Electricity doesn't flow in the wire. It travels in the electromagnetic fields surrounding the wire so the speed of travel is limited by the dielectric. Free electrons in a conductor actually only move about 0.5 cm/second or something. It's actually really all a mess. It's only at DC that something like 44% of the energy is carried by the electrons. Above 100 Hz it's all fields. If you thought electromagnetic theory is a disaster, you should look at solid state physics. Those guys must be clamoring to throw themselves off tall buildings. If you actually heard the "theories" they've come up with to explain free electron flow the scales would fall from your eyes.
SchuKo is the short form of “SCHutz KOntakt” which means protected contact or secure contact since the connector has 3 contacts including the PE (green yellow) contact
@@MyPlayHouse it's like if you stab yourself with coffee coffee is not like water, it's an energetic "drink" from italy, so small portions with high sugar and caffeine
@@MyPlayHouse I have the same setup Ecoflow 100w panel and Ecoflow River power station and 48v adapter charging my little Ebike. She's 6 years old and 4800 km's on her and me, was so happy I bought another bike. I use a 60v 5a PS to charge it faster than an adapter. Always watching *cheers* *73*
Only a stupid person would do what you suggest. He gets free solar power, so he can charge his bikes etc, and power a few things when the mains power goes out. Rather than putting food into a non-existant well to rot.🙃
I brought a few dozen hard drives before the pandemic because some guys were selling these 750GB and 1TB drives in enclosures to me for $3 each. Most of them are SATA and I tested them to be good. There were a few that I was not able to connect and didn't know what it was until recently I found out that that they are SAS. Was looking for a way to connect to the SAS drives to test them out. I got some connectors from Aliexpress that went from SAS to SATA but then found out that you would need a SAS controller card to be able to detect the drives. So the external SAS drive seems to a viable solution just to test the drives. I did see that same exact drive at Amazon for over $100 even with a coupon. Great that you have this video and myself and everyone able to learn about the experience.
For my DC... We have a bin of a 10G DAC cables... But a lot of our servers go 25G now.... My company stock AOC (Active Optical Cable), it's a cable (fibre + 2 transceivers hard wired), and it's nice to manage yes, but one faulty wire... Left a bad experience for me, much rather regular DAC copper cables 😂
Hey Morten! I just had do unmount old DL380G9s that was being decommissioned.... Those friggin things were heavy... Dual socket 128GB ram haha... Worst things is that the railing kits were stuck in the rack. The lever didn't work and uhh I used a flathead screwdriver :P btw did your DCs get Gen 11 yet? Awesome video man.
So if I understood it correctly, on RAID 6 when one disk fails and is replaced (e.g. by hot spare), no parity/checksum calculations need to be done to recover and there is no downtime??
That is correct. When a drive needs to be rebuild, all the data and checksum is available on the other drives,, and it does not need to do the calculations. If a disk dies on RAID 5 it has to do that,,, but there is also no down time on RAID 5,, it can do this while working,,, it might work slower, and take longer to rebuild.
Easy fix if reset button by itself faild. Hook a brake light to the charger output through clip leads to the cells directly bypassing the BMS Then charge to 3.4V per cell. If a cell group is bad you will need to disconnect test and replace the bad cells if found. Next apply the same voltage to the output teminals. Then hit the reset switch to allow communication with the charger. Finally recharge as normal. ❤
@@MyPlayHouse I went back to wired headphones so that I can listen to my music cds through my home stereo receiver. My Sony WH-CH510 works perfectly with my chromebook and my cellphone. 👍
My battery was blinking the lights in the same way. I followed the simple procedure in the video and fixed my battery within minutes. THANK YOU MORTEN !
Are you still in Portugal? In the Mikrotik interface you can check the system health (don't know the exact place right now) which should show the input voltage from the battery. That will not be the true battery voltage because of drop in the cables, but it is something.
