    3D Printer Enclosure

    You want to run it on new style Makita batteries? https://www.ebay.co.uk/itm/18V-Li-ion-to-for-Makita-Adapter-18V-Ni-cd-Ni-Mh-Batteries-Converter-M-U-/193499504996?

    Old Imperial Cable?

    I think there's some of them there actually.  My mistake I read 7/.029 instead of 3/.029! It is dark in there. You can just see the bunch of wires in front of that grill to the left of the door.

    3D Printer Enclosure

    I finally finished my Makita battery to Champion circular saw! (Finished the second set of parts to convert the BiL's one too). The saws were bought with two Nicad batteries and charger, in their own case, years ago, at 75% off marked price for £25 when a Focus/Do It All was closing. Never seen...

    Old Imperial Cable?

    Looks like they ran all the cables to where the cu was going to go then just stopped. Same with the ceiling, half done in T&G. Pianos, slate bed billiards tables, mowers, furniture, cars, most of it rotten: It just gets better:

    Old Imperial Cable?

    😂 I have no idea. It's that house clearance I said about, well more a smallholding. 5 acres plus with multiple outbuildings with asbestos roofs caved in/leaking. Gems like this coming out of there.  Just a pity it's not mine.

    Old Imperial Cable?

    Barn find! Literally. A started /abandoned rewire...in a barn. From some sleuthing, seemingly the stuff below is polythene inslated cable with a pvc sheath to BS1557. So 3-cores, red, white & blue, no earth, Imperial 3/0.29 I think, 3 tinned strands per core equates to about 2.98mm2. It's...

    Transformer Identification

    Interesting, the inside of the earlier version of the unit, on the left, compared to the later design on the right (they do the self same thing). I remember now damp used to affect the open frame pots: No luck on finding info on the 120VAC primary pcb transformer (on the left) either. Part...

    Transformer Identification

    I did think of that. Space in the panel, on the DIN rail, is ridiculously tight  but I haven't ruled it out. A one module wide 230/115 DIN rail mounting trannie is a maybe!

    Transformer Identification

    I bought a 120VAC unit cheap, s/hand from the States. Thinking to desolder the 120VAC/?AC transformer from the board and stick a 110VAC transformer on the primary. Then measure the secondary and figure a new 230VAC PCB transformer from that. The original was an FPD1901 220. The US one is an...

    That's the car ramp fixed.

    It's the Sheppach one. People praising them over in the mig welding forum. This sort of result:

    That's the car ramp fixed.

    Funnily enough I've just bought an Aldi portable bandsaw for cutting up some 80 and 100mm box section. Plan is to make a car rotisserie. Getting tired of always cutting with an angle grinder for 40 years now hence the bandsaw.  Will have the option to lift via farm jacks or a couple of old...

    Confused

    Check out the Schneider Si RCD range. Available as 30mA. Good for inverters in my experience.

    TV thinking I'm in the Highlands!

    If in a weak or fringe reception area then a band specific rather than wideband aerial is what you want. These guys are my goto. The knowledge base is excellent. https://www.aerialsandtv.com/

    The Vaccine...

    Given the choice I'd have the Oxford rather than Pfizer. Don't know much about them but get the feeling the background development they did on the Oxford one on the back of SARS and MERS makes it safer. As an aside the lad I did my apprenticeship with has been left with long Covid. Had it and...

    Extend wire, how?

    1 inch or 1 foot?

    Central Heating tripping RCD?

    Did they actually take the lid off the motorised valve(s) or just give a cursory glance? It's only one screw but do so with the power off.

    Transformer Identification

    I've ordered a 2KVA, 0-15V transformer from RS that should fit the pcb. I'll need to break one track and bridge a couple of others as the secondary pin out is different. Fingers crossed.

    Transformer Identification

    Yes, scribble to the right it the PCB track. Odd that the secondary isn't taken from the two outside pins... The 4 diodes of the rectifier circuit check out OK. This then from the regulator datasheet: R1 in this case is 270R, R2 is 2400R. Not sure about IAdj so I just plumbed in 100uA as a...
