The display I installed is available from MPJA.com

I’ve used the usual free-standing table top fume extractors, but they’re noisy and always seem to be in the way.
So, when I was reconfiguring my bench, I built the extractor into it.
It consists of a cheap $10, bathroom vent fan with a couple of PVC connections from the intake that run through the front of the bench. From the exhaust side, a long pvc pipe runs along the back of the bench, and blows it against the floor 6 feet away. Sorry, no pictures of the steup on the back of the bench… although it is on wheels, the fully loaded bench weighs a few hundred pounds, so I don’t move it often.
The intake is Loc-Line anti-static vacuum tubing, from loc-line.com This is a series of 2.5 inch diameter, hard plastic segments that interlock to make a flexible tube, and capped with a rectangular nozzle. Part numbers: 81302AS, 81304AS.
Nothing fancy, there’s no trim ring around the intake. The switch on the left of the intake controls the fan.
The flex-tubing is connected to a PVC elbow, that elbow is just press-fit into the intake. This has worked well, it is easy to remove and to adjust.
I was using the Hakko FX-951 units, but upgraded to JBC.
Here’s the JBC DIT and JBC compact with micro-tweezers.
At the back-right is a DS-983A solder dispenser.
On the left is the intake for the fume extractor.
The rework equipment, a CSI-474A desoldering gun, and a CSI-825A+ hot air unit.
New Mantis Compact inspection scope arrived, with articulated boom arm. The Mantis on the left with the standard binocular AmScope on the right.
This scope provides a great 3D view, without peering through little eye pieces. The Mantis provides a much sharper image than the Amscope’s optics. And you can shift sligtly while looking through the Mantis and change your perspective of the board, this is very handy for getting a better perspective when working on small devices.
The AmScope is still handy for high magnification (up to 200x), but most inspection work is in the 4x – 8x range, and the Mantis is great for that.
The optional articulating arm provides good reach across the workbench, and was a worthwhile option.
Mounted on an articulating arm, which makes it easy to position the scope, change viewing angles, and folds out of the way.
Tried out the SPI decoding capabilities of my new DS4024.
Very nice! It took a little playing around to figure out the settings. Since SPI isn’t completely standard, you need to make sure that the high/low option is correctly configured for each channel.
The picture doesn’t really do justice to the crisp image on the screen. Click the image below to zoom in for a clearer view. The screen is non-glare, but the camera seems to pick some up (more than I can see).
The DS4000 series oscilloscopes are big. Compare the 4000 to the DS1052E on the shelf above it.
Various meters over the years. The probe type meters sound more useful than they’ve really been.
Bench meters: BK 5491B, Agilent 34410A, Rigol DM3068
Hand held: Fluke 289, Sinometer IT803, my 23 year old Metex M-3650B, BK 2709B, Extech430 & 505, BK 879B
