content: I agree a Dremel tool can do it, but expenses could be high (not only on purchasing the bits, but carpel-wrist fatigue too). You're right about a drill press taking up space, but low cost table-top units are cheap these days. I made a trepanning tool from a broken drill bit and it has lasted a long time. For cutting straight lines, a miter-box and careful use of a fine pitch hacksaw can be useful as long as the pcb will fit. I do like your use of the Dremel for the pot though..I found another good video, for those interested.

content: Those islands look good, but just curious, is this cheaper or easier to work with than protoboards?Obviously, for some SMD stuff there is an advantage (but I believe some veroboards can be used for some SMD, and I'm not sure how easy it would be to manually get tiny islands for SMD stuff anyway).Just curious about the advantages, other than the fact that it looks nice.

content: bare single sided laminates are defiantly cheaper than protoboard,If i had a drill press at the time, I likely would have ended up going down this path, but as i didnt, I now just lay out and home etch any board i need quickly,This method is not that great for anything involving IC's whereas the dremel one can likely get by. but yes it would kill your wrist after about 40 circles.

content: You''re right, little chunks of veroboard - the kind with a solid ground plane on one side. (I don't have much and I'm running out) can be cut off pretty easily and it works pretty well. (Its just perfboard with one side completely covered with copper if anybody knows where to get more, I'd like to buy some. My stuff is old, I got it at an estate sale, I didn't buy it from any current sources).Quote from: kalel on 2017-09-12, 04:08:01

content: Update on this channel:I wager this channel easily passes 5K subscribers by years end. Equal to BigClive's channel (over shoulder hand's on view and no BS) with similarly successful combination of honesty, humility and professionalism.People, go subscribe.Question to the OP:Not suggesting you're a clone BC's or Julian's channel, but can you tell us about your work background and what your plans are for the channel? Are you or will you be committing to a certain quantity of videos per week?Suggestion to the OP:When subscriptions go up, viewers may expect "more of the goods" in a shorter time. So think about eventually shortening the nice peppy intro a bit (I suspect it could be cut in half) and do more of Dave's time-lapse chipmunk stuff (or your fade-cuts) to pass over longer segments.

But the OLED screen is pretty awesome with individual illumination for every pixelBut still unsure if this is a good buy at this steep price? Any thoughts?http://www.muralikarthik.in/2017/08/LG-OLED-TV-4K-UHD-SMART-TV.html

content: It comes down to what you intend to use the TV.To decern 4K resolution, on a 65" screen would require a viewing distance of just 1.2m. to decern better than 1080p would require a viewing distance of less than 2.5m, which is fairer. so its likely such a screen would have more apparent resolution than 1080p, but how much comes down to how far away your sitting to it.At any given time, your colour vision can only decern a 1000:1 luminescence difference between the brightest and darkest point of your vision, so contrast ratios of higher than 100,000 are well outside of what you can see, if a single pixel towards the center of the screen is bright, you cannot tell black from very dim, its only if the entire scene was very dark, when your black and white vision takes over where 1,000,000:1 ratios become the limit of human sight, exceeding this is beyond what you are capable of telling apart. Are you planning to watch pitch black video with limited luminescence, or are you used to moves where the contrast is inflated for average people to be able to see whats happening?Personally if i was in the market for such a TV, i would go looking on a auction site and get a 2 year old one for under $1000, but i am a scrooge.Each pixel being able to turn fully off can reduce the faint grey glow in very dark scenes, but for $9000, i think i can live without it.

content: Quote from: hkmurali on August 12, 2017, 04:38:58 amThat screen belongs in a stadium - and is a bargain price. For a 65" version, thatisa bit pricey.I, too, have had a keen interest in the OLED technology - long before Sony released its rather expensive 11" screen. While sizes are going up and prices are coming down, it is indeed the longevity issue that is making me wary of taking the plunge - and my concerns are threefold:1. The relative changes in emissions between the colours over time. With the blue spectrum being an issue, it means the colour balance is going to change.2. The total change in emissions over time. I'd hate to see that decline become noticeable.3. The potential for burn-in. With LCD this wasn't an issue - but now with this type of active pixel ... it's back.What I am interested in is the progress with quantum dot. As I understand it, that should at least be able to mitigate the first of my concerns.

content: I just watched the latest Voltlog video. I like this mailbag of misc junk from China. I should make my own. Nice joke in there. My pot plants should similarly benefit.I do like the dry delivery.However that's not why I am writing. At 13:32 (ish) he opens a kit for an Amp based around the LM1875 20W amp chip. And I was pretty sure I recognised the circuit diagram artwork as the distinctive Silicon Chip magazine style.Sure enough it is from a project dated December 2004. Anyone care to comment on the capacitor changes. Specifically why the non-polarised electros are changed.

content: By conventional electrolytics I think of the aluminium foil types that we've had around for decades.Without going into details, these capacitors need some DC voltage to help maintain their internal structure. Without that, they can degrade over time.If you have some electrolytics you've been "saving" for a few years, it is wise to put them through a some electrical calisthenics before pressing them into service. This is often called "reforming".With the signal being presented, there is not going to be any useful DC to help maintain a polarised capacitor, so that's why the original design would have specified NP caps.The el-cheapo Chinesium kit has ditched this for the less expensive option... which is going to last long enough for any "warranty" questions.

I doubt that anyone would be heard to complain that their morning coffee tasted odd because of mains interference or distortion, but there is an entire industry that will try to convince you that without their mains filter, sinewave reconstruction power supply, isolation transformer and/or $5,000 power cables your audio and video systems must be horrible (and your coffee will taste like cat pee as well!).Mains distortion is commonly cited as something that will cause the soundstage to be contracted/ compacted/ eliminated, and that the distortion will cause a loss of clarity, soften dynamics and mangle the bass 'slam' from your subwoofer. Naturally, we can expect that micro-dynamics will be damaged beyond repair, and the 'air' between instruments will be cloudy and grey with a 35.7% chance of reproductional ineptitude.

It's bad enough even placing a drink next to an expensive piece of kit like a transceiver but if you do spill anything on it then you need to get it to a repair shop like yours QUICKLY.I have heard of some brave souls who spilled coke/tea/coffee on equipment then immediately gave it a good wash under the tap. This might work but you need to make damn sure that you get all of the water out afterwards, and I'm not sure about water seeping between the different layers of the LCD.

Distilled water or alcohol works much better since it has less contaminates as tap water.The biggest problem with surface mount technology is there are usually some type of voltage source like batteries in there for the micros. These are the first things that need to be removed. Even then a lot of times the damage is already done.I get liquid damaged smart phones in here from time to time. Most are non repairable because the owners do not take out the battery. Unlike Apple products most smart phone batteries are easy to remove.Thanks for taking the time to stop by and commenting.

Although in modern times we use routing switchers for video where we have complete flexibility to send a signal to any number of destinations, etc.It was the whole concept of an analog computer that baffled me even back in the early 1960s. Even then I couldn't see that you could do anything with an analog computer that wouldn't be easier and faster with digital computation. And be able to solve several simultaneous equations while the analog computer seemed to be limited to one at a time. A concept perfectly illustrated by the ability to play "Space Wars" on the PDP-1. You probably couldn't even program "3-card Monte" on an analog computer.

There are an absolute ton of engineering problems that require those functions, and analog computers implemented them directly.The title is not accurate: It's "SPACEWAR!" not "Space Wars" and dates from 1962; MIT received its PDP-1 in 1961.

content: Before retirement I use to both purchase and have installed these kinds of control valves, we used mostly Fisher control valves. The last model had all the electronics, I/P, and feedback link, all mountedin a small plastic box mounted to the valve body. Using a handheld communicator one could perform automatic valve set-up and calibration after installation in just a couple mins. Rebuilding the valve body was a machine shop function. Typical valve size could be 1" to 6" with a few even larger. Costs with accesories started at around $2K and up depending on valve size.

content: This is a switched mode only regulator. So there will be some more or less detectable output ripple and the dynamic response to load changes is usually relatively slow. How good it this specific regulator ?As the cheap labtop and similar supplies are often less than 25 V, there is not that much use to using a unit made for up to 50 V.The screen and user interface looks reasonable good.A cheap lab power supply (e.g. 18 V 3A --> 2 A usable) might not be much more expensive than the module.

timestamp: March 25, 2017, 08:54:46 pm
content: Your feedback is always good to read!I know it is a switch-mode only and said so in the episode, my point was to explain its features since the datasheet itself doesn't do it properly! I had to figure them out myself and try stuff. A laptop supply is just an example, you can connect any form of DC input as you well know, but this one is mostly available. The other modules for 30v or so are similar price and similar size.Maybe you are right, 20$ for this + 15$ for laptop charger might be near the price of a cheap specialized power supply. However, the availability is the big issue! at least for me!If i want to buy a 60$ lab supply, it would cost me another 100$ or so to ship it here to Jordan let alone customs if I wasn't lucky. However, in this setup of mine this doesn't exist.So the video is more or less my problem and my quick reasonable solution to it, as you can hear, I said that I still recommend a true power supply if you can afford it.___Anyway, I will be starting to make a PCB for the power supply in my thread... a prototype board. I guess making a video series for it is nice. I will use CircuitMaker to do so. I found a local PCB manufacturer that I will try, but components have to come from digikey.
