Whats your Work-Bench/lab look like? Post some pictures of your Lab.

My bench...in need of some cleanup.

What's that type of big scope above the curtain rod? 

All those horizontal lines, it's got to be a logic analyser.

[AF6LJ]

Nice benches folks.

Thats an external monitor for my TEK784D oscilloscope which if you look close is on the bottom of that stack.   I have a replacement LCD screen kit on order.

Nope, TEK784D with waveform and FFT display active (Pink hashy line).

Joke seems to have missed - probably a language barrier.... Anyhow, they're talking about your airconditioner

cheers,

Now that I re-read the post and see it's above the curtain rod rather than below I get it.....doah....

Thanks for sharing. It looks like you have some homebrew stuff (with the keypad, for example).  What are they ?

There are two homebrew items with keypads in the picture. 

One is a precision frequency reference based on a GPS (NEO 7 i think) receiver.  It is capable of output from 1Hz to 12MHz.  A PLL stabilizer is active between 4.6 and 11.7MHz to reduce the phase noise you get from these kind of sources.   It's all run by an Arduino Nano and has a built in frequency counter.   It was a fun project...my first using a PLL, and my first where I used an Arduino in a permanent project.
This project was inspired by one of Skulcom's projects but I added the PLL and an output low-pass filter.  Also the software was largely re-written but credit to Skulcom where credit is due.

The 2nd chassis is an electronic load.   This was also inspired by one of Skulcom's projects.  Major changes were made to the analog circuitry and software however.  The unit is working well in it's core functions but I am still tinkering with the software to make it work better for automated battery discharge testing and transient load testing.  Tested max specifications are 70VDC, 100W, 4A. 

In the photo are also two homebrew pulse generators.  One is described here: https://www.eevblog.com/forum/projects/avalance-jw-charge-line-pulser-for-step-waveforms-~45v-out/msg1405898/#msg1405898.  It is a avalance charge line pulser with <600ps Trise.   The second pulser is a reed switch based device with an even faster Trise of approx 400ps.  It has adjustable output voltage but is not particularly stable as the performance of the reed switch isn't as good as I had hoped.  Still it's a nice testbed for future reed switch testing.

Also high in the photo are two homebrew precision current sources.  A 1A unit which can be dialed down to 10mA or so and a 50mA unit which can be dialed down to 50uA or so.   Both units have a full-scale calibrated position.  The 1A unit is accurate to +/-50uA after 5 min warmup.  The 50mA unit is accurate to +/-2uA.

There are more projects as well.  I've been busy this past year.

Do you have a link or more info on the PLL part? I have one of those GPS modules waiting to be built into a frequency reference and it'd be great to add a stabilizer.

Here is the schematic of the as-built unit.  Hit me up with questions if you want.

[bitseeker]

Thanks. That's pretty cool. I think I got how it all works. One question: Is P2 one of those 7-segment LED display frequency counter modules?

Lot of nice benches around here, I'm currently planning to build one with the help of a friend.
Here is a quick sketchup plan I made. I would be happy to have your opinion about my design, would you change something in terms of dimension, space between shelves etc.. ?

Thank you.

1.5 m width? Put horizontal bracing under the shelf's and desk, otherwise those shelf's will start sagging over time.

Yes the width will be 1.5m. Indeed I was thinking of building a frame for the desk and the two shelves. Something like in the picture below but with the bracings along the 1.5m dimension....

You could consider a bench built like the one in the image below (specifically the bottom half that makes up the frame for the table top). As per table bracing, just complete the rectangle just below the table top; front to back bracing won't be necessary IME. Leave the bottom framing as-is, as you'll be able to get a chair beneath it.

Thanks. That's pretty cool. I think I got how it all works. One question: Is P2 one of those 7-segment LED display frequency counter modules?

Yes...one of those cheap PIC based units I had lying around.  This one was nice because it went all the way down to 1Hz whereas the other cheap counters usually have a minimum frequency.   I think I paid something like $5 for the kit.

Another Design built using 2x4s and plywood.  The top is made from two pieces of 3/4" marine plywood laminated together for a solid bench.  The edges are painted for looks.  The entire assembly breaks into four pieces with just 4x  5/16" bolts for easier transport.  The width is 1" narrower than the door frame in my house and the length was chosen to fit the space.   The shelfs are made from 3/4" plywood and just sit on the top with a bit of rubber glued to the base for non-slippage.  Note the pockets on the underside of the bench for meters and other small items.   Finish is marine varnish.

I recently made this from three inexpensive hollow core doors (2 x 540mm + 1 x 900mm for the top), two strips of dressed wood and some castors. Works really well and is very inexpensive if you want a bench that is as long as a door is high.

Nice job

A mere ~3months  after moving to a new place I setup the lab-table again.

Ikea table 120cm wide and 80cm deep.
Top shelf on 40cm legs, 40cm deep.
HPAK E3640A powersupplies, 2-ch 62MXs-B 600MHz scope, SDG2042X siggen, HPAK 34401A and Fluke 177 DMMs, Olympus SZ51 microscope with LED ringlight, Hakko FA-400 and FX-888D, SR620 counter.

AC-outlets are now below the top shelf, but I think it's cleaner to mount them below the main table at the back.
Might build a wider (2-2.4 m?) similar lab table in the future.

Is the top shelf from Ikea? If so, do you have a name or part number? Thanks.

Nope, top shelf is a pine gluelam board from the DIY store, and the 40cm legs also. The legs had M8 adjustable feet which I removed and instead bolted the shelf from above to the legs with M8 countersink bolts.
