This RAM+ card is driving me nuts. Keeps faulting on Bank 2 parity error randomly. Yanked the RAM, tests fine. swapped banks around. Yanked the 74 series chips, tested them in the TL866. Fine, i am kinda at a loss here.

The possession I have owned the longest: a hulk Hogan lunch box that I've had since preschool. Sadly repurposed for something else when I was in junior high 😂
We're starting to lose the prisms in CD optical pickups due to age. Delaminating, hazy. Sony KSS-180A
Meanwell LRS-350-5. I have an entire stack of them and they all fail the same way. The 5 volt regulation dies so it runs between 7 to 9 volts. It's happening at an alarming rate, so I need to figure out why
Another year, another VCF. VCF Southeast is slowly being put together. I won't be exhibiting this year, unfortunately.
First tornado warning I have gotten in many years. That was an unusually strong storm

I need to setup a test environment for the new development, so it's time to drag out and fix the underdog... Rough shape but we can handle it
In better news, the weather star 4000 hardware emulation is going smoothly!
How my day is going.... FSK Subcarrier/IF radios SUCK especially with no schematic or alignment instructions.
Keeping the gravel driveway clear of grass and Moss has been an exercise a futility
PSA: Older LCD TVs and LCD TVs in general cannot be preserved like CRTs can, first known instance ive run into thus far of an LCD TV going Vinegar Syndrome.
It's been 7 years since I've looked at this, but I need to finish the reverse engineering of the data card to get back into a schematic
The Weather STAR 4000's Original ROM vector toolbox is fully working! More and more of the original spirit is being restored everyday as we are getting super close to true STAR 4000 emulation as well! More to come later!
Just got my first severe thunderstorm warning of the year
Here is something you don't see everyday. Someone sent this crazy thing in for repair, very odd led sign That's not built well at all
New fear unlocked: age related HDD head coil adhesive failure

Did not expect to see the WeatherStar 4000+ Simulator (weatherstar.netbymatt.com )on a CBC News report! www.youtube.com/watch?v=ZDne...
I bought these at a flea market back in 2008, and I'd love to be able to find another set just like it
Moment of truth. Does the Sharp PC-5700 power supply run with the new TL494 installed on the depotted hybrid? Let's find out!
Rendered by the Weatherstar 4000's original rendering engine in ROM. I am actually stoked about that, more of the originality has been restored!
As much as I do not like AI at all, it can be a useful tool if used correctly. It has worked out a functional example of the Weather STAR 4000's original rendering code in ROM using Easy68K!
Any of you connector aficionados out there, any clue what this is and what its mate is? It's almost the thickness of the PCB itself
Picked up this really nice Sony watchman recently, this one is a little bit unusual because the CRT design is different. It's not curved
Time to pull apart the Sharp PC-5700 and see if there's anything we can do with it!
Picked up this cute little '50s Muntz in the Chicagoland area last year, I do need to find the knobs for it eventually. Any vintage TV collectors with a box full of knobs who may have the set, please reach out!
