We recently bought a Siglent 4 channel scope to replace our old trusty Rigol.
One of the challenges we had is that the equipment shelf is a bit of a reach since our bench is deep.
This cheap (mostly) DIY solution made a night and day difference!
The ability to move the scope all around the bench, bring it closer to the DUT, especially when probing those hard to reach areas, and easily move it out of the way with one hand, is a life changer!

The arm is a standard gas spring VESA monitor arm that you can get on Amazon for ~$35.
The Siglent VESA mount adapter was 3D printed using PETG-CF, from a free tried and tested design by printables user aeberbach. It's an ingenious design that uses the scope's handle as a lock mechanism for the bracket.

After using it for a while, we figured that we were missing 2 things - a handy storage compartment to for probe attachments, clips, etc., and a probe hanger to solve the unavoidable messy entanglements of the probe wires.

Then we thought, "why not add a DMM to the bracket?" so we did.
Our trusty vintage HP DMM was way too big and heavy, so we settled for a cheap XDM1041 digital DMM that works well for most of our daily needs. They come under different brand names, but are all the same.

Then we designed a bracket that attaches under the scope mount, and you can see the results after several iterations and improvements. It has a convenient accessory compartment, and a probe hanger for all 4 probes on the right.

If anyone is interested in the print files for it, let us know and we'll share it online for free of course. The idea can be adapted to any small DMM that you already have, but the files we have are specific to this model so we weren't sure if anyone would be interested.

Have a great weekend!

Hi all,
My Xiaomi Robot Vacuum S10 keeps failing its self-inspection with the voice alert "navigation sensor is not working." This is the second vacuum I've lost to the same LiDAR (laser distance sensor) fault. Until now I've just replaced the unit, but this time I'd like to fix it.
Has anyone repaired this?
What usually causes it: failed LDS motor or belt, a dead laser/receiver, or a loose ribbon cable?
Where do I buy a replacement LDS module, and is it a plug-in swap?
Any teardown guides or videos for the S10 turret?
Things I should check first (cleaning the lens, bumper or turret jams, firmware reset)?
Happy to share photos or test results. Thanks in advance!

Hi,

I replaced the joystick that was drifting and did a messy job. Some traces seem to be affected. Despite it all, the joystick seems fine apart from down doesn’t get to a full 1 value. But the bigger problem is that the L2 trigger is registered as being fully held. Is this salvageable?

My 15 year old grandson likes to take old VCR’s, radios, and other electronics apart and try to figure out what’s going on. He was looking at Kline multimeters at Lowe’s tonight and wanted to get one. What is a solid but affordable one that would be good for him?

My left analog stick made a crunchy sound and started feeling really off. When I opened it up, I determined that this little grey piece seems to be causing the issue. On my right stick, it stays flush while moving the analog stick. When I push this left one into place, the moment I move the analog stick it pops out of place and ends up slanted. I took it off to figure out why it's not stay in place, and one of the sides are a bit deformed.

Does this piece have a name? Where can I get a replacement piece? I'd really like to avoid ordering a brand new stick box just for this tiny grey piece. Any help would be greatly appreciated!

This has a voice recording of our grandma who has passed, and my sister took it out to change the batteries, and in doing so one of the wires to the speakers came off, and one of the battery posts broke off. If I hold the battery down I can kind of hear it playing, so I am hoping it can be fixed, but not really sure where to take it, just an electronic repair shop?

As you can see the control button overlay is damaged. Is there a place that makes stuff like this?
For that matter can you just but the Lexan material?

I did find this company that makes these things.

Hello, has anyone here ever replaced the cells inside the LP-E4 battery pack? If so, were you successful? I've swapped mine out, but I believe it'll need some calibration, but I don't think I can force a calibration myself.....the charger has charged the battery pack, but the camera still shows it as empty, so looks like it's out of calibration of some sort!......thanks.

Have had these Crusher Evos for years and they are my favorite headphones by far. Of course I had to drop them, and now they refuse to connect.

They were gifted to me years ago, but I'll do anything to get them up and running again.

When plugged in, music can only be heard on the right side, but both haptic drivers thump away. "Power on" still plays through both speakers, but it no longer says "pairing," nor does it appear in any bluetooth menu.

I took them apart but see nothing abnormal or disconnected. I'm thinking it's an issue with the motherboard itself. Any ideas?

I have a 43 inch atleast 10 year old AOC television and recently I see this dark speck on the bottom left corner. It's not always present. I can read subtitles/see the picture through that speck. Can anyone tell me what that is and how does that happen? How to get it corrected? Thanks.

Hello everyone. I would like to try to repair an Old Subwoofer. Can someone help me identifying this part?

The one with the "LT-Sub2" marking ripped off the board. I soldered it back to place and I am able to start the Subwoofer and get sound of it - so far so great. But over a certain level (volume/bass) it just turns itself to standby. The part I'm holding is part of the Power Switch - that do I know.

I think that part is the one that is broken.

It's a Teufel C200USB Set, the subwoofer a Teufel CC200SW If that matters.

I would really like to get it working again.

Thank you very much!

Hi everyone,

I recently bought a OnePlus 6 and I’m trying to power it from a bench power supply instead of the battery with the battery removed bms board. Voltage used: 3.8 V

Problem:

The phone doesn’t turn on or show any sign of life. While handling the connector board, I think I damaged it with heat while solding.

Questions:

1. Any ways to check if the bms board still works? (I lost the battery)

2. Should I buy a new battery or using a battery flex can work? If yes can you show me one?

Any other tips are well accepted, thanks
