    Data wall plate connectors

    Thanks, but I've found a company that makes a vast array of faceplates and connectors, DataPro.net [Mod Tidy-up]

    Change My Motherboard Myself? Need Recommendations

    I've done this several times over the years. My approach was to first choose a board that appears to meet your needs. Obviously, it has to fit your case or a new case if you want to upgrade that too. Ask a lot of questions here and elsewhere before you decide. Then select the memory brand and...

    Data wall plate connectors

    When I upgraded my security camera DVR I discovered that the new model does not support a wireless mouse. The problem is the DVR in in the garage while the display is in the adjacent room in the house. Consequently, all connections between the DVR and display must pass through the wall. With...

    Have all the UPS makers switched to no consumer battery replacement?

    Yes I suppose you are right, Blue. Seems so wasteful though.

    Have all the UPS makers switched to no consumer battery replacement?

    The new BE550G works great, as expected. This morning I took the BE350R to Batteries Plus to see if they could make it work. Turned out the battery was fine but the unit itself was bad. So, I'll buy another BE550G. Makes one wonder if there's anyone in the Electronics Forum who might know how...

    Have all the UPS makers switched to no consumer battery replacement?

    Thanks! Just ordered one from AmZn $84.53 inc tax, free delivery.

    Have all the UPS makers switched to no consumer battery replacement?

    Thanks, Dave. Actually, the one that needs to be replacement is BN450M, purchased in 2018 as I recall. Battery is not available from APC and manual says it's not user replaceable. Looking for one that is user-replaceable, I turned my focus to one I've used for my laptop for much longer, a...

    Have all the UPS makers switched to no consumer battery replacement?

    I've used APC UPS for years and they had the battery behind an easily opened door making battery replacement easy. Suddenly, in about 2019, such units seem to have been "upgraded" to "no serviceable parts inside." Although there are independent online videos shoring how to do get the case open...

    Rain gauge resetter

    As it turned out, that wasn't even close to the "end!" It was merely a proof of concept, living entirely on the Arduino UNO board. After that came implementing it on a breadboard with DIP socket for the chip, transferring the Arduino program from the chip on the UNO board to it and testing it...

    Wiring common ground for 7 components on enclosure lid

    Thanks, Harold. Someone, perhaps you. suggested this before. The problem with it is its size. The enclosure I selected early on is too small. In addition to the quarter-size proto board PCB there is a relay module occupying the bottom, and 5 buttons project down from the lid.

    Wiring common ground for 7 components on enclosure lid

    Thanks for the alert, Blue. There's a a trade-off between reliability and ease of repair. If I left out the disconnect points a single button failure requires re-wiring the whole thing. BTW, a ELegoo male pin fits tightly into a ELegoo female.

    Here's a closeup of the bus:

    Wiring common ground for 7 components on enclosure lid

    Decided to work with ELegoo jumpers, i.e., pitching the header and building a bus with female ELegoo connectors. You will see I'm use BlueJet's "solder all together" idea, but with the ability to disconnect things easily: The bus for the grounds is at the left. The black female lead that's...

    Wiring common ground for 7 components on enclosure lid

    The jumpers that came with the Arduino are round (or seem to be) with 0.020" diameter, while the ones from ELEgoo are square 0.020" on a side. I've sent a note to Vetco regarding their header. I'll do the same for ELEgoo . The glue would be if I wanted to change one component connected to the...

    Wiring common ground for 7 components on enclosure lid

    Now that I've done all that soldering making my bus I've discovered that the male connectors on Arduino kit jumpers and the ones from ELEgoo.com fit rather loosely in the header that I got from Vetco. My DVM measured resistance doesn't waver as I jiggle a connection, but I'm a little worried...

    Wiring common ground for 7 components on enclosure lid

    Here's my "bus" fashioned from a 12-position header: poormansbusMediumQ.jpg Not proud of the soldering, but my DVM shows that all positions are connected.

    Wiring common ground for 7 components on enclosure lid

    Ok, we have a Plan D. I thought about that early on but it seemed inelegant. Not that it would matter, since my project is a one -off and no one else will ever see the inside of the box;) Maybe I'll do it. Thanks.

    Wiring common ground for 7 components on enclosure lid

    Here's a Plan C: Suppose I used one of these: https://vetco.net/products/12-pin-stacking-headers-for-arduino-etc I could bridge 8 of the contacts with a short length of bare solid wire. The 7 ground leads of the components would be fitted with one of these...

    Didn't work. Maybe a Knife tip for my little Weller?

    Wiring common ground for 7 components on enclosure lid

    Thanks. I can testify that solid is not good and neither is through the hole. Been there, done that! Regarding insulation, I don't know if I can strip segments at each negative contact. I'll try cutting with a wire stripper at each end of a segment then slicing lengthwise with an Exacto. But...
