Testing the DPS5015 with USB coms module. I guess the basic thing works but I find if I get much over 55w output the controler resets and the USB connection is dropped (not sure which happens first, whether the dropped connection resets the controler or simply the controler resets and thus the USB connection is gone..). With a 30v/3A input it should be good for 90w or so, can't get near that without it dropping out. Need to do more testing to figure out what is going on. Output voltages seem to be accurate though, I ask for 5V and that's what I get

Edit: It may be seeing the two power resistors (effectively 0.5 Ohm) as a dead short which I guess could be upsetting it...

Saw this locally, snag it cause its damn cheap about $10  , and was not expecting too much from this price level. But after played with it for about 30 mins, actually its quite decent. And also as the twistable 2 shapes (gun vs straight) is pretty handy too.

Next is to tear it down as according to manual it uses 3 NiCd cells (3.6 V) inside, wonder if can be modded to fit in a high current discharge 18650 Li-Ion cell with cell protector & charger, as the handle volume is more than enough to fit it in.

Sounds like eGan FETs and an LM5113 driver. Good guess?

Short and misplld from my mobile......

Just some bits and bobs from the local surplus store...

Brought 7 days ago the DIYINHK lens kit turned up in the mail to go on the Microsoft LifeCam Studio that took 5 days from Sydney  so my aging eyes can keep seeing the smaller and smaller bits 

Followed the 4 year old video and in 10-12 minutes including desoldering the old lens in my 44 degree shack. Quick check with some shaky hand held snaps on low res and all looks great 

Working distance seems around the 150mm range and maybe 20x25mm or a bit larger area.

Obviously not.  It's in case the first one get filled up with TEA.

My Rigol Calibration kit just arrived from TEquipment. Interesting that their photograph is completely different from the product itself...

That sucks, I'm sure you can return it if it doesn't do what you want.

Looks like this is the product in the picture: https://www.rigol-uk.co.uk/Rigol-DS6000-DK-Demo-Board-p/ds6000-dk.htm
Rigol DS6000-DK Demo Board Our Price: £190.00 (228.00 inc VAT)

Part number DS6000 vs DS6000-DK?

Part number DS6000 vs DS6000-DK?

Thanks, but that is exactly what I need. I had a strong suspicion the photograph was wrong all along, as the Rigol cal procedure calls for the multi-cable setup and not for a board - which you are right: the DS6000-DK is the demo board (which I don't need).

I sent a PM to the resident TEquipment account around here to let them know about the problem. Hopefully they read private messages.

Exactly!

I finally received my stackable silicone banana leads. Against my better judgement I ordered them from far away lands. They seem okay. The resistance is very low, which indicates they didn't skimp too much on the materials. They are a bit tighter than I'd like them to be, but using them a few times helps. One plug crapped out almost right away, so the judge is out on the quality. Might have been a dud, or the durability isn't that great.

I'm yet to have a go at them with the soldering iron to see how the silicone holds up.

Yesterday I got some LM2576T-5 G's from RS Components.  The order was for LM2576T-5 G, the stock number was for LM2576T-5 G, the antistatic bag the parts where in said LM2576T-5 G, but the components where small surface mount 3 pin devices that look like linear regulators and most definately not TO-220-5 devices.

Obviously I will return them, but as the anti-static bag has the correct stock number and part name, I'm worried I will just receive the same wrong part back again.

I've also now found that 2 of my 5 ATTiny85s from RS are DOA and might need HV fusing... or are totally dead.  Not really worth returning at £1 each though.

That doesn't sound much better than a generic Chinese source.

Well, the two LM2576's I got from a British seller, which are probably from China and not much cheaper behave awfully like linear regualtors.  Voltage drops from 5V to 4.45V when you pull 0.5amps through them.  When RS hopefully sort the order out I intend to straight swap the component and see what happens.

HP 214B vintage pulse/delay generator.    Vacuum tube output amp.  + or - output up to 100V into 50ohms.   Ext or int trigger.  Double pulse mode.  All in all a nice unit, just heavy and in need of some TLC.

I hit the mother lode at the thrift store today. Nearly 20 NES, SNES and Atari games for roughly $25. Some are in rough shape, but having daily drivers is more fun than prestine collector's items.

I'm debating going back for the Atari 2600 and two more games. Not as cheap as the rest, but it'd be a neat console to add to the collection, even though it's not part of my childhood like the rest. No TV connector or power, though.

I bought a bunch of Raaco Assorter boxes to store machine screws, nuts, washers and various sizes of lugs.


They are not terribly expensive and I couldn't find something similar on Aliexpress quickly.

[rx8pilot]

That is marginal even for the ultra-low cost.

For reference - I got 4" vises recently, they were over $1,000 USD each. Very good quality.
The ripoff version from China is about $250 through US distribution. Quality is marginal.

Mean Well HLG-185H series with CC/CV capability and adjustable, 185 watt rated at (36V/5.2A), used and working fine, both for about US$15.

Coincidence, everyone buying machinist vices? I need one too. Something like this:
  https://www.aliexpress.com/item/QM100-4-Accu-lock-machine-vice-with-swivel-base-table-vise-machine-vice/32731773536.html
Hoping to find something second hand that will do.

[PartialDischarge]

Is everything CNC related all THIS expensive?

Good quality stuff is. Brands like Sandvik Coromant or Seco make the best tools. And when you see the work it takes to make end-mills for example, from steel manufacture to thermal hardening, you'll realize that it is not that expensive.

This is a nice catalogue of everything cnc related, although you'll only need the smallish stuff for your cnc, they are well known in Europe not sure if they deliver in the US.
