Some 80s "New Product Information" Samples/Folder thingies - Page 1

content: I recently bought a decent lot of components for $100, and at least some of the stuff looks like it belonged to a firm that dealt electronics for some sorta energy thing (I think? I forgot). Anyways, among the many interesting things were these "New Product Information"/Promotional folders samples and whatnot. Most of it is National Semiconductor(my favorite being the switchers one with the Floppy! I hope I can archive that..), then a Signetics 8051 sample thingies. I have a couple more behind what's pictured. Unfortunately these weren't stored in the best of conditions, so the staples on the pamphlets are rusted, folders are warping, etc.. I mostly wanted to share but I still don't know much about them - like if these samples were some sorta subscription or something sent to EEs.

Back then there were usually coupons in the paper magazines, to require more info and/or samples. Destined mostly for companies/universities/students.Happen to have a clock/timer just like yours in the first pic. Bought it in the 90's from a flea market, sealed in the same blue blister. Not of much use today, other than maybe for collecting/nostalgia purposes. Cool tech some decades ago.

X-raying Fluke TL 175 probe - Page 1

content: Do we have anyone here who can X-ray a Fluke TL 175 probe? I have one of the probes failing and would want to try to shave the body at the pin to lead junction and resolder the connection, but need to know where to open it. I love the probe, it would be a shame to let it go.Edit: I mean X-ray their own probe, I just need to know where the junction is inside the body.

content: Its probably broken on the probe side, just at the strain relief, no?What I did was verify that is the location, then cut down the strain relief to the insulation of the wire, then cut the wire a bit higher to give some space to solder.

timestamp: June 14, 2023, 01:11:23 am
content: That was what I thought too and I cut the lead at the end and then cut a a quarter inch of the probe body at the tail, and resoldered the lead wire, but that did not help. The failure was somewhere inside the probe. It is a known issue with Fluke TL175 probes. So I went ahead today and cut into the probe first closer to the tip but hit shiny metal, so did another cut in the middle of the probe and found the junction by trial and error. As shown in the attached pictures, the lead wire is crimped to the tip and apparently the crimp quality was poor. When you pull or push the lead wire at the tail you get unstable probe resistance between 12 and 0.3 Ohm. I used a blunt nail and a couple hits with a hummer to re-crimp the joint and probe resistance measured close to zero Ohm, so the connection was restored. I still went ahead and soldered a short jumper between the tip tubing and the lead wire as shown in the photo.Now to repair the body, I think I will get a JB Plastic Weld and fill the opening, then sand it to the shape.

content: I think what I would do next time and what I would recommend is to drill a 2mm hole 2...3mm to the right of the "FLUKE" logo (you can get an idea from the 1st photo where to drill) until you hit the tip metal, then use a blunt nail of a small diameter and hit with a hummer with low to medium force to re-crimp the junction inside (put the opposite side of probe body against a a hard surface for solid support) . Measure the probe lead resistance before and after while pushing and pulling the lead wire at the probe tail. If continuity readings become stable, you fixed the problem. The small hole then can be filled with epoxy, polyurethane or silicone.Edit: I'd drill through the black part of the body, this will make the repair more inconspicuous. Just size from the photos where the hole need to be drilled. Obviously with this technique your can only re-crimp, not solder.

content: The interesting motion sensor I've encountered used a simple resistive light sensor, old school cadmium that is a little flat white disk. Obviously does not do the whole job but (the toy) had code that checked a couple times each second, and responded when your hand came near.So, the code had to know what ambient conditions were, in terms of the cds resistive output, and do some action, when that simple reading had a large enough change. Likely one channel in the processor, for doing A to D conversion.The range of that was for if you waved your hand near the cds sensor, so perhaps not for self-driving systems, but rather a simple TOY.I hadn't tested for what kind of room light had to be present, or if it worked outdoors...I think the cds sensor was invented, maybe 1930's ( ? ).

The options are numerous, but all of them, no exception, seem to be made-in-china. Whereas I am aware that some Europe based manufacturers do exist, they do not seem to be operating in this price range at all.Are any of you aware of some non-china-made consumer drones in this price range?Thanks!

content: Quote from: brumbarchris on June 10, 2023, 07:00:35 pmThere is no way for an EU manufacturer of anything to match the production costs of a Chinese one. The material costs, wages, various administrative & regulatory burden are vastly higher in the EU than in China. There are good reasons why all the cheap stuff you find in European shops is Made in China.If you want Made in the EU you will need to pay (significantly) more. There is no way around it, especially not in this low cost retail space (if you even can find a consumer-oriented manufacturer in the first place). For industrial/professional applications it is a different story.Not sure whether you have tried to price the components at any point but for 200€ you won't be able to buy even a set of motors and a controller board, even less anything with a camera if you wanted to make a drone yourself.

I finally got a concrete non-estimated reading by my retailer.I phoned them up this morning after they had a few days to process it.I was £44 in credit. Hmmm... "That's not what I was expecting.""That's after your credit settled your quarterly bill."So my quarterly bills where £320 or there abouts. So I saved about £364 or about 30% last year!This year I added an off grid solar power source for the office, with some incremental upgrades it should, I hope, take another 25-30% off that bill next year.I'm basically down to the high power stuff. Laundry, oven, coffee machine. Those are a little harder to replace with off-grid gas or small scale solar. However, I have finance clearing on the natural gas heating upgrade and hope to take out more finance on roof top grid-tie solar. If I schedule high power items for sunny days I could cut my quarterly bills to <£100!

Some sort of survey, sniffing around is not serving my purpose anyhow. It feels snoopy and the cellphone does these brief snoops as if by procedure. That's why I consider that brief survey activity to be outside of my personal needs.How hard would it be for logging that traffic, of others around me, I don't know. But a listing saying 'Karen's WIFI' (from nearby neighbor) is kinda creepy.

The issue is as short cables and and may heavy strength at the sockets.Then analyzed how the MMCX deals with hot and GND connections:- hot looks good- GND is loose within the connector and socket. The ring (red in picture) made the connectionsThis let me think, that no tailed connections exists as for the GND and MMCX claims up to 6GHz support as up to 500 connection cycles.What are your experiences or what are an better as SMA/SMB/MCX has a clear GND connection?Hp

content: Hi There,As we are growing, we are in the need to streamline our operation. We are still quite a small company, but handle lots of PCBs and need to keep track of all the Boms, orders and so forth. and the excel sheets no longer is sufficient to handle all this.Solutions like SAP Business One are still quite expensive (30-50kUSD implementation cost) and difficult to really choose over the 1'000s of solutions that exists.We manufacture machines that involved many pcbs, some cnc and other parts.What do you guys use / recommend as an ERP for small companies like us?We basically need- Inventory/warehouse management with barcode system and bins for all the electronic components.- Hierarchical BOM management able to generate PO- Follow up of orders- Follow up of productionCheers

content: Check out this similar thread, might have some info for youhttps://www.eevblog.com/forum/manufacture/recommended-erp-inventory-system-for-pcba/?topicseenThere is Inventree which is open source which might be worth spending some time playing with, considering its free.Also since its actively in development you might be able to flick the developers some money to add any extra features you might need.Much better use of the money than buying yearly license to use custom software

It works, is cheap, but isn't particularly user-friendly.At a previous place we used Sage 50 Manufacturing, I quite liked it and I think it ticks all of your boxes. It seems to have been replaced bycim50which looks pretty similar as far as I can tell.

content: Amazing, they even got downforce to increase the load on the tyres to generate more grip.There seems quite a bit of software going into that. Choosing the fastest instead of shortest route requires a decent model of the mice motion plans&costs in advance, especially with the complete freedom of which turns to take.I don't think these competitions never ever get "solved". Sure the initial intent of route planning on a robot is "done". But the competition brings the clever tactics to get a slightly faster mice. And at some point the rules or mazes get changed which would present new challenges or design freedom.It would be next level if they would use different surfaces with different grip levels as well, and have the mice account for that during each run. Similar to how a racing driver would account for dry/wet driving lines where in dry you want to race on the rubbery stuff, but in wet you want to avoid it all costs.If a mice could scout 3 routes, e.g.: shortest but lots of turns, longer with straights, and some middle ground, and then throw in some grip variable. Then have it decide which one to take based on it's best knowledgeI'm sure the software of those bots is full of carefully tuned closed loops to keep it on its desired route. Maybe adding some trickery could throw some mice off and require it to be even more clever. The scout run seems ideal to plan the 'ideal' route, but going slow wouldn't allow for measuring slip. You'd probably get some crazy solutions like adding a 5th wheel that's driven at some power, have the other motors regenerative break for a net zero acceleration force on the mice, and then measure the loss between the 5th motor and the power that's regenerated that's due to friction on the surface.Anyhow, I will stop daydreaming aloud now. Was a fun watch, and looks even more fun to build one.

Among things I don't like is pegboard, which covers most of the walls and is set out by furring strips (nominally 1" x 2"). Mice do get behind it. Here is a picture of a couple of the furring strips after removing the peg board. (I am still a novice with my new camera -- sorry for the quality.) Every dark dot is a pneumatic driven brad nail. He used glue coated nails, and needless to say, they are a royal pain to remove.This is just a light post and is not intended to be a serious discussion, but my guess is that he took out his frustrations with a much younger, recent wife with his nail gun.
