There are many crimping tools out there that look like they should be OK.
But the difference between a sloppy generic crimper and the proper dimensions is night and day.
Even if the sloppy generic crimper looks superior.

The video is nice but nothing. Crimping pliers without conversion are useless, the only problem - bought inappropriate pliers.
Crimping pliers only with gear - great attention has to be paid to marking the jaws - crimping pliers on video are for non-insulated car connectors - FAST-ON. It is easy to see the gap at wire = wide jaw = deformation = can not be used for displayed connectors  :palm:
Everything works as the weakest link in the chain

I've lusted after an EV4, an EV4 Off-road quad or an EV4 semi-recumbent, for years.  I'm just too inept to afford one.  :-[

what do they even cost? website doesn't seem helpful in that regard. They look like fun!
If I recall correctly, the off-road quad is somewhere around 5 k€ (8 kAUD), and the semi-recumbent a bit over 3 k€ (5 kAUD).  Definitely worth the price, I hear.

The SN-28B is the most common crimper sold in China expressly labeled for “DuPont” terminals. So he bought exactly what the vendors say to buy for the application in question!

I have a few Chinese crimpers, and none are very good. Regardless of what type of terminal they’re for, the precision of the jaws is too poor, and produces unpredictable results (or predictably bad ones).

The text I marked in red are the parts where I have no idea what you are trying to say.

I use the engineers crimping and wire strippers. That are japanese precise but manual tools. With sensitive use and when you know how to do it right, you also get the best results.

Crimping pliers with a gear have a bigger push - thus a stronger wire capture.

I have several interchangeable jaws, they look the same - each crimp differently - depends on the initial shape of the connector - core clamping ratio and wire sheath (varies with the length of the facets / for one wire, for multiple wires,  wire size) - standard - AWG / SWG / mm2 - there is much variation.
Chinese crimping pliers stand in CZ 300,- _ 700,- CZK, High quality pliers (Knipex, Wiha .....) 1500, - _ 18000, - CZK by type and design.
I use Chinese pliers but good jaws - after a small adjustment it works. Pliers for data cables can not be edited - I have the original 3800, - CZK

Just sold my part of my soul and a Kidney to buy a Siglent SDG2042X Sig Gen. and a new seat to drive it from. For the Aussies $130 delivered bench height base.

Looks like Beans for the week (and next) again .....  >:D

Anycubic Photon 3D printer and some engineering resin claims to have Tg>120C.

Will be interested how you find the use and cleanup if you are only going to use it for ocasional jobs? What video I have seen of it the results look very good :)

Those are surprisingly affordable. Please let us know how practical it is.

I have chosen to avoid Resin printers and stuck with FDM because of the cleanup. I use plenty of Epoxy in my R/C stuff but you only need to mix what you need for that.

Pulled the trigger on one of these bad boys!  >:D

So it arrived yesterday! Man is it quick! REALLY quick!

It wheelspins and wheelies all over the shop if you think it's a silly wee kids toy to be abused and not a very torquey wee beast that will throw you as quick as look at you if you don't go easy on the "GO" trigger and keep the power turned down!
It can be driven with relative ease if you select 1st speed, single motor and set it to "eco" mode, anything above that and you have to be careful on the trigger!
It has 3 speed settings, 1, 2 and 3 strangely enough  :) It has single and dual motor settings and an "eco" and "turbo" mode setting too.
Top speed, dual motor and set to "turbo" and it's scary! You need to see this to believe how fast this wee thing can move! It obviously doesn't have a turbo but "eco" is around half power and "turbo" is full power. You can also set it to only power from the rear wheel which is 1000w or both front and rear which is 2000w.
Single motor, 1st speed and "eco" mode is nice. Dual motor 3rd speed and "turbo" mode is totally wild!
Single motor, 2nd speed and "eco" mode is nice on the bottom end but top end of that will get you to 40 Kph and your bum starts clenching as it is very torquey even right up to top end!
I may post a couple videos once I get used to it properly.

I would recommend it for getting around so long as you don't get above your skill level and wear the proper safety gear. So far as pot holes and stuff the little ones really are no problem but the bigger ones you need to skirt around. It's similar to driving a fast car or bike but just on a much smaller scale. You don't have to roast it... but you can!  >:D
Sparks and Smoke means i'm nearly there!

I finally got my first DC electronic load. It was quite cheap for a 400w model, and the fan is temperature controlled.
I bought it from eBay (look for KP184). 150v / 40A /400w. It is easy to use (not like some BK precision power supply if you remember the video).  ;D

I tested it @30A with my 1000w power supply and the cables started to get warm. Absolute coolness.  8)

Sorry for the dumb question.
Is the bnc a source sensing voltage input?
Whoah! Watch where that landed we might need it later.

I guess it's the external trigger input.

Or a current monitor so the current transients can be viewed on an oscilloscope. Some loads have this feature. Odd place irregardless of function.

The chinesium manual is...

well Amazon indicates this :

Quote
Note: about the BNC interface function, please know the follow function of BNC before you use this Extended function. If the voltage measurement is selected as the remote measurement (VOLTAGE REMOTE SENSE) in the menu settings, the BNC connector on the front panel must draw two wires to the positive and negative terminals of the measured voltage, otherwise the voltage measurement and display There will be inaccuracies in the error, especially when the load is loaded

Well, sensing ("far sensing" in the manual).

Thanks guys, that is what I thought. I had to laugh, my initial post I incorrectly put 'load' sense, d'oh, the DUT is the source!

My 3rd Datron 4000 Calbrator with Option 20

This one is not working.
No Keyboard commands.

Both output lines were broken off connectors.

I also have a chance to pick up a few Fluke 5440B/AF units with no display.
Would it be worth while? Haven't asked for pricing because I wasn't sure what to do with more calibrators.
