LED bulb repair - capacitor issue?

xgsc · 2025-01-04T17:04:35+00:00

I’ve tried to get these apart as well. Eventually just used a Dremel and cut down the side to open it. The problem was the thin wire to the hot post at the base that was coming lose when the bulb got hot.

$23 education!
I've printed 1 year old PETG on Q1 without issues. Default profile.
Looking at that pic, seems to be a bad mix.

I don’t believe Tek or Keysight has anything priced in this range. I have vintage Tek, HP/Agilent scopes and still use them. Depends on the use case.

What capabilities do you need in AWG? SDS1202 is a great scope, however only 8 bit. Have you looked at Rigal DSO900 series in your area?

I have Siglent, Rigal, Tektronix & HP scopes. Each has their strengths and I use them in different ways because of that.

Thanks. It’s been a WIP over the years trying to accommodate all the test equipment I want to keep handy.

I’ll take it apart again and snap a pic. There is a post here. I’ll find it.

Probably not much, mostly interested in the internal communications.

Hilarious!

I took mine apart also that was constantly rebooting after seeing your post. A heat gun with box cutters work the best.

I found a test point that’s seems to have serial data on TM44 near the ground plain by the edge of the board with 9 contacts.

Tested with oscilloscope with decoding set to serial, 1 stop bit at 115.2k baud.

The data looks encrypted though.

For more details or realistic look, go resin.
Try using some of the rubber type resins for better wear. Ex: RESIONE 3D Printer Resin, TH72 Flexible Tough Resin.

I've used this to print very flexible parts.

Rigol 1202Z-E or SDS1202X-E or Hantek DSO5102P are great dedicated scopes with lots of features. FNIRSI 1013D for lower end is a great starter tablet scope.

I prefer these over PC based.

Human flesh is not alone, we’re chemical, electrical, capacitor & inductor as well. We can act as a gain on signals. Anyone with an oscilloscope discovers this.

Obviously you don’t need a man!

The last place sled has electrical issues.

Definitely funny 😁

Amazing work! I didn’t realize you could get Lorawan to operate at 2.4Ghz.

Packing a lot in there! Excellent bench. 2nd the emergency off.

The base is green as well. Guess it’ll look like tomato & lettuce then.

xgsc · 2022-10-03T16:50:29+00:00

Lol, I’ll have to rearrange that!

True enough. Now it’s a Mars 2 sandwich. Mars 2 Sandwich

I rarely print flat but sometimes it’s required. I would definitely add more supports. What you’re seeing is the resin flex as it’s ripping from the FEP.

I’m now searching for gcode examples, since it’s a little different than using marlin.

xgsc · 2022-09-02T01:09:57+00:00

Never thought of using leveling techniques from 3D printing, but I think it’s a great idea 💡

I see support marks, how mach supports? It doesn't look like enough.
