Micsig MS310 Handheld Oscilloscope Teardown

Borrowed this along with a Sony HandiCam with HDMI outputs to test an HD-SDI receiver circuit.

Man, I didn't really notice all those strands of that resin goop until I looked at the pictures.

Focus stacking with Helicon Remote and Helicon Focus as software and Nikon D750 and Tamron 90/2.8 as hardware.

At the Caps game (Caps FTW!!) last night, someone kicked my phone from one step into my beer that was sitting on the step below. I didn't notice for a while. The beer-drenched phone was very unhappy.

 

Since it's not working anyway (turns on, none of the buttons work), I figured I would perform some surgery to see if I could clear the circuit board of beer gunk.

 

Update: I washed it with water first to clear the gunk, then cleaned the circuit board and the buttons (after removing it further from the housing) with rubbing alcohol and a q-tip and let it rest over night to dry. Now all the buttons work, but I can't get a signal at all. But hey, at least I can get all my contacts off the phone!

The hardware was defective, so I put it to good use.

Raided the PC spares box again today, as it was raining heavily for most of the day.

 

This is my previous main motherboard, now redundant and, apparently, gathering dust despite being both bagged and boxed to protect it!

Idea for a tiny digital picture frame: Use the display from a digital camera.

Big chip in center location is the cache tag SRAM, other two are L2 cache chips.

Rigol DP832 Power Supply Teardown

This week I've been spending a little time trying to breathe life into printers. In work it's been clogged up inkjets, and at home it's been an Epson Laser with an interesting error: D1122-

 

The error comes up almost instantly, leading us to believe that the problem was likely to be RAM. Fortunately Dave had a collection of vintage PC133 DIMMs that we could blow the dust off. Sadly all check out with the same error, so I'm now thinking that the problem might be a corrupted boot ROM.

 

I'm sure I'll get to the bottom of it sooner or later, but for now enjoy this macro view of some RAM sticks.

i can excuse the 2mm jumpers (none of which were included), bad spelling, and hand soldering. but a dead short from output to VDD sort of implies that this $60 dev board wasn't tested! :(

 

maybe they need some pogo pins?
