I got myself a laser "pointer": A 270W 915+980 nm diode laser for a price that was probably below scrap metal value
Me wants one too Already got the required power supply
Me wants one too Already got the required power supplyAh that looks familiar, I also have one of those.
Is this one fully working as per front so 0-45V and 0-70A on 400V three phase power?
I ask since mine is one of many coming from a dutch company and seeing the 12NC dutch company sticker on the front I suspect the same.
Delta modified them in a special way so it does not act as the original design.
Mine is more like 0-60V and 0-45A strange behaviour in a fixed power configuration.
Via via I have gotten the reverse modification instructions so if interested contact me. I have still to do the modifications myself
My Nuclear Enterprises RM5/1 ratemeter just arrived!
Seriously guys, if you like geiger counters, pick one up! They're basically given away on ebay! I got mine for like 25$.
They work with both geiger-müller tubes and scintillation probes, and have a voltage range from 300-1400V.

I'd be willing to build it myself - would a meter like this be a good starting point? (more flexible than the ones that come as kits?)

Agilent U1253B from giosif. A single alkaline battery lasted 15.8 hours so not nearly as bad as the 8 they said even if that was probably for the rechargeables. On high brightness, DCV, with about 6 hours using the bluetooth IR accessory. The rechargeable that was in it lasted significantly less time but my new 9V(8.4V) lithium rechargeable haven't arrived yet(the ones I have are all in my smoke alarms). Also for the last 20 minutes or so of battery life the readings were not very stable.

Nobody else may care but just to follow up... Using some EBL 600mAh 6F22 rechargeable lithium "9V" batteries I got 18.1 hours battery life even with using bluetooth attachment for about half the run time. In typical lithium fashion there was no period of instability near the end it simply died.

Its newer OLED cousin (U1273A) has this on the setup menu, which helps with "sudden death".

It's just like the 1252B where you can select 7.2V or 8.4V but not primary/secondary. It was kind of odd but when selecting 8.4V(which the battery reads when full) the battery indicator never reads full, with 7.2V it went low but unlike alkalines it didn't flash the x on the battery(or it did and I didn't see it which the alkaline did for an hour or so.) So for some reason the battery doesn't really work well with the indicator but 7.2V is what I'd recommend.
Mean Well 24V/65W SMPS, Schurter power entry module, JST connectors to replace the external power adapter of my HP Z3805A.
While it's not (strictly speaking) a piece of T&M equipment, I did just buy this.
Picture of a nice car
I am not ashamed to admit that I've already done a bit of teardown on it. And yes, I'm enjoying learning its user interface!
Ah, the Evora GT Nice to see British cars in the USA.
