Ordered myself an EEVBlog multimeter. Like I need another multimeter... the scary thing is this will be the newest one I own.

A DP832 arrived yesterday and within a few minutes of using it on a project, it helped me find an issue to fix!

I really like this power supply so far.

A buddy of mine just arrived in Brazil from the States. Brought me a Macbook Pro and the Practical Electronics For Inventors book, I've skimmed through it and it seems a bit more intuitive than the Art Of Electronics. Hopefully I'll be able to fix the capacitor on my old 15"Macbook Pro (according to Louis Rossmann) and give it as a gift to my girlfriend. BTW, that's a palm rest decal on the notebook, in case anyone is wondering the color difference.

I just received this in the mail.
It is a diamond tipped hole cutter drill bit that can be used to make isolated pads on a copper clad circuit board. It is usually used for drilling holes in glass, ceramic, etc.

This drill is 5/16" (8.1mm) outside diameter and 1/4" (6.3mm) inside diameter. It will create 1/4" pads. Other sizes are available if you want other size pads.
This drill is made by DiamondSure and can be found on eBay for about $15.

Here is some info on pad cutters:

Thanks for sharing, that's a good idea.

Very nice idea.

I have seen small sets of these diamond core or hollow drills around before but never bothered with them and now that I have seen a practical application I can justify the purchase.

Many thanks.

Ooooohhooooooohhhh

I only have 1" and larger hole-saws at hand, so I guess I'll have to use tubes.

I've seen people use ground planes for patching stuff onto PCBs, but this makes it really easy. Thanks!

HP 3488A, 44471A, and (when it arrives) a 44470A. It was the cheap way to get a scanner.
Planning to do some longer data-logging experiments with my HP 3478a and various things I have around.

They don't look like a bad little unit for around $400AUD or $290US, available down here from Bunnings or Masters (don't go to Masters FFS), If you didn't already have a milling machine, pedestal or bench drill then these might be a valid option, the base table looks very nicely machined in another video and they are bit bigger than I thought they were.

Random Youtube video and there are plenty of others.

Very fine tungsten wire, less than 0.1mm in diameter and 99.99% tin.

I wasnt 100% convinced when I looked at the bosch bench drill. Still better than the cheap HW store (chinese) brands.

My school used to have a lot of nice pcb drill presses, but had to get rid of them since they lacked guards etc.

MrSlack · « **Reply #1418 on:** May 15, 2016, 08:36:10 am »

Probably better than my Sealey pillar drill. Everything wobbles.

You or the drill? (or perhaps both?)

Probably getting towards both in my case.

Not really something I bought, nor today. But I finally got around to testing the crate full of transformers I got from a colleague a few weeks ago: all 40 KGs of them, none of them have specs on them

Some are crap, some are useful, one is scary: comes from a microwave oven (I guess) and has a 3.5V and a 2500V output, yikes.

Also visited that big Swedish furniture store. Got a new chair, a nice drawer that fits under the bench, and a load of clear plastic crates for all the other parts.

Iedereen Koopt Er Afval? I swore to never go into that store again and order their stuff online -if absolutely necessary- even though it takes them 2 weeks to deliver.

The joys of being married. Sometimes sacrifices must be made to keep the missus happy, so I might as well get something useful out of it.

The bang for buck factor isn't that awful for the stuff I got. And the dimensions of the drawer and crates are exactly what I was looking for

nowlan · « **Reply #1423 on:** May 17, 2016, 07:14:15 am »

Dont like how the drawers are under the desk. Means you cannot sit close enough to bench. Need legs under desk for good posture.

I have tried it, epic fail. Way too uncomfortable to lean over to work.
