My latest meter arrived today. It is a sound level meter. A CEL 393. This is a early microprocessor controlled class 1 (high accuracy) meter. CEL393.jpg On ebay from a seller who obviously knew nothing about it. There are two versions of the meter that are visually identical not even a different par...

On the original battery replacement I just took my 20+ year old Breitling Aerospace watch in for battery replacement. It has to go back to Breitling. Got a call Wednesday saying the jewler had been contacted by Breitling saying that the movment was obsolete so they would have to replace it at a cost...

Pat beat me to the Bristol description. I'd gone to bed...
Used on avionics and some jukeboxes and to keep on topic, Collins TE.

Robert.

Don't get me started on tools for fastner heads. Male Hex: Metric (AF, BA) and Imperial (AF, BSW,BSF). Female Hex: Metric and Imperial. Other female: Pozidrive, Phillips, JIS, R+P, Spline (5 and 6 point), Torx, RIBE, Bristol. Plus security variations And because I do aircraft stuff you can add: tri-...

I paid £75 for my E8510A which while not Jammy Git is a pretty good buy.
I'll not be accessing it remotely. It will be nce to access the DMM and 'scope from any PC on my internal network though.

More TE incoming. I just bought a Agilent E8510A LAN GPIB gateway. So in theory I should be able to access my instruments anywhere.

25 CPS said "The 0.75A fuse in the top left of the cluster of the four did not look healthy at all and measured open. I don't know why the end caps turned colour but the fuse holder didn't. I had purchased a full set of fuses a while ago for this machine at Sayal but they only had minifuses so ...

Yes properly organised car meets with the site owners permission are common and not a issue. The problem is when lots of barely legal (at best) vehicles turn up un-announced and start making noise and smoke (burn-outs). This is fundamentally illegal. These people don't care about others. Note they g...

I've had another look at the Advance OFS-2B frequency referene. Thanks to Frequency I have a manual. It's clear the unit is not operting correctly even when fed a generated 200kHz signal. The AGC deos not seem to be working proprly. Unfortunatly the circuits in the manual do not match the unit I hav...

The transformer is the little toroid with 3 windings. Operation is odd. One winding seems to go to an oscillator on the mains side, one drives the main switch MOSFET gate and the third is feedbck from the DC side. I think the feedback saturates the core cutting the drive. I was able to dig out the f...

I picked up a bit of TE on Thursday. A HP 8920A communication test set. It was a Buy It Now on ebay. Only acouple of pictures of the front. "for spares or not working" with a note that the power supply was blown. Price was only £75. Collection only. No time to ask questions, I hit buy. I t...

AVGresponding beat me to it. My plug in hybrid has regenerative braking that operates when you lift off the throttle as well as when you press the brake pedal. The level of lift-off regenerative braking is driver selectable using paddles on the steering wheel. At the higher levels of regenerative br...

Almost certainly a custom made unit. The box is a Greeenpar modular one. Removing one screw, furthest from the longitudinal joint lines and the side connectors, should allow the cover to come off. You might have to loosen the other three slightly. Can't even guess function without a internal picture...

Update on the Pultra lathe. It's a bit of a hybrid. The tailstock from a earlier P type like the bed. The tailstock is lever operated and seized solid. "4 hours in penetrating fluid did not allow any movement by hand. A bit of heat from a hot air gun and some careful tapping with a soft block a...

The Pultra I got isn't as tidy as that one. I've fancied one (or a Schaublin) for years. Didn't think I'd get one for £40. I've already got a possible line on a cross slide. Looks like mine is a bit of a hybrid. It has an earlier bed probably a P type and a 1750 headstock. Not an issue, it was a fe...

I went to the Dunstable Downs amateur radio car boot sale today. As usual I was looking for TE but came back with mostly mechanical engineering bits. :o Find of the day was a Pultra precision lathe. I think it's a 1750 but have to check. Certainly 50mm center height. These are small machines, I can ...

This muppet, mjtronix who according to his ebay listings breaks up working test equipment has now stooped to breaking the edge connectors off and stripping tantalums and TO100 ICs from PCBs before trying to sell them on ebay

Zenith and I expect to be at Dunstable Downs RC boot sale on Sunday. Looks like good weather, so see you there

How the hell did this get onto cell phones and deaf people? I finally had a hearing test a couple of mont's ago. As suspected my high frequeny response is shot (1kHz is 6dB down higher frequencies 30-40dB). So I now have hearing aids. At SWMBO's insitance I got the fancy ones with bluetooth. As well...

DRL's are front only without rear during the day for good physiological reasons. In daylight conditions the PERCEIVED difference in brightness between rear lights and brake lights is much lower than at night. This running with rear lights on in daylight increases the reaction time of following brive...

Always nice to see a wandering trace snap into sync as a Rb locks

Just be careful about lighning protection. I know of one case where a GPSDO was connected to a rack of expensive equipment and it took the lot out when the antenna took a direct attachment.

Not TE directly but I went to look at a PDF manual yesterday and could not access my NAS drive. It's a WD and I found out today that WD have been hacked and shut down their servers. The frustration is I can't access MY LOCAL drive without WD's systems being up. Nothing about that in the instructions...

Where I have trouble with packing TE is the logistics of boxes for 19" rack size equipment. The correct size box for say 3 or 4U is not easily available so you have to cut a bigger box down in height and have excess space. Even then the minimum pack size at a sensible price is 5. Even then they...

The WOW screwdriver offer (I only got $2 coupon) comes to £28 (~$35) shipped and tax paid to the UK. I don't do enough work with that size screw to make it worthwhile to me. However the UK price for the same drivr is £45 so still worth shipping from the USA if you want one.
