Optoma WU515 DLP Video Projector Lamp Connector Replacement
This particular Optoma WU515 ended up with a partly burned lamp connector. I am not 100% sure of the cause as the lamp was also pretty burned but the lamp's pins were still at the correct height and hadn't slipped back. That can happen if the pin in the connector is not latched in all the way. In the female end, the burned connector looked to be pushed back. I have a theory that the connector was cracked and may have fallen apart slightly when the new lamp was installed. The pin of the new lamp, could have pushed the connector in the female end backwards, allowing this weird damage caused by arcing inside the connector instead of inside the arc tube.
The projector was pretty dusty and had a full filter. Fortunately the ballast was fine and after some wrangling of the ferrite bead on the new lamp connector wire, and some contorting hand positions the projector was working again.
Clean your projectors at least once a year. Ideally every season(every 3 months or so) if you use it regularly.
I am cleaning out some old gear and decided to harvest some of the innards of this PG-M10X Sharp Notevision projector. Its a decent projector for its day but not useful for much of anything today. Made back in 2000 it was probably expensive. construction does not remotely match what you see today.

A few years ago, I worked on another PT-RW330 for a gym. They had never cleaned it or bothered to do anything aside from run it and that led to its UV source dying. The cost of the replacement source was prohibitive so the projector was not repaired. While trying to find parts, I located this particular PT-RW330 on eBay with a description saying the picture was good. I had even emailed the seller to verify it was not purple. he said it was not.
When this unit arrived, the first thing I noticed was the post-it left on the bottom that clearly said," Purple Tint".
I ended up getting most of my money back after the guy tried to argue with me until I sent him a picture of the postit and I left this on the shelf to lookat "someday". Where as most "someday" things end up as "never day" things, this one was different.
Most of the parts I buy come from Time Electronics in China. They are a great resource for me and they have helped many viewers I have sent their way. I talked to my friend Crystal who works there and I mentioned that I was trying to find a source for this projector to make a video but the costs were just too high to justify it. These sources are $300. That would mean it would cost $300 to fix a $300 projector.
Crystal offered to send me the laser source for free! I could not thank her enough. Time Electronics really helped me out and because of them, I can share this repair with you.
Give Crystal a shout at

I recorded this back in 2017(I think)
This snake-oil electronics device claimed to repel insects and whatnot with high frequency noise. They said it will eliminate all pests just by plugging this in to an outlet in the affected area.
At the time we had an issue with fleas and were trying all sorts of solutions. I was pretty sure this was not a real device but since I bought it via Amazon, I knew I could return it. Upon receipt my skepticism went into high gear.
These are total garbage with their claim. The Piezo element(if even real) is connected to the neutral line of the AC only. There is nothing driving it at all. Every bit of circuitry is to drive the LEDs. LED's only. There is nothing making any noise.
I actually contacted Amazon to get this listing removed. They claim to care about fake items but it took me 6-10 contacts with video and pictures to get this fraud seller removed. The seller even contacted me and tried to bribe me to remove my review slamming their product as fraudulent. After 3 weeks, Amazon or the seller finally removed all their listings for these snake oil boxes. There are others up there claiming to do the same thing and I suspect they are fake too.
If you like these debunking fake electronics stuff, let me know and I will order other items that I think are bunk and tear them down for us to see.

Had a day job customer send in this projector after they experienced a melted connector. Unfortunately the issue was caused by the connector not being seated fully. Personally I think this is a design mistake by Optoma.
I replaced the connector with a harvest harness from a scrap unit. The fans and chassis really needed a thorough cleaning as you will see.

This is an old (14 years) Viewsonic DLP Projector (PJD458) that was donated after the customer experienced shutdowns after a few minutes of use. I found a bad fan and some dust to clean and got it back up and running.
I ended up re-donating it to someone who needed a projector and was fine with the resolution for their purposes.
If you have any questions about your own projectors, head over the Reddit
https://www.reddit.com/r/projectors/ There is a wonderful community of folks who are great about projectors. I post their a lot and its easier to get the help you need.

I strung some LEDs that are serial addressable to this metal thing and made "art". Its nifty. Runs on an arduino and 50 WS8806 LEDs from seeedstudio. Weezy cat seems to like it.

I think it went well. I'll do another stream soon.

This is the Powerlite 8100 that inspired this video. https://youtu.be/cXgflt5o0IU The owner had installed a new projector lamp and noticed the green was blurry/distorted and was not able to correct it with changing any settings.
The projector was found to have a melted or warped coating on the green side of the final LCD prism .
Here is the picture of the damage. https://i.imgur.com/a8z4hOP.jpg
Unfortunately this is not a reasonable repair as far as I can tell. The only real option is to replace the entire optical assembly (LCD's, the prism, polarizers etc). The cost to replace this in a 7+ year old projector is not usually reasonable. The owner ended up buying the other projector at a very good price so he can use all the same setup that he had before. This projector may be repaired if a suitable donor appears, or it can be scrapped to keep other projectors running.
