Ari [APz] SovijärviEvery now and then when I buy boards to be repaired, people throw in a total loss board or two. These are good for extracting parts that I might not have at hand or just to have a good laugh before pressing F for the poor, manhandled board.I previously posted a Sega/Stern WhiteStar platform driver board that had battery acid all over it. That is odd, because the board has no batteries, but there are batteries on the CPU board that's directly above it.Now I got to the CPU board that was probably the cause of that acid bath. And it's glorious! Some poor sap has been jumpering this thing, without neutralising the problem and it has some extreme corrosion in the traces. This one might end up framed in my office, next to the one that had a burned hole because of using an iron nail as a fuse.<a href="https://mstdn.games/tags/pinball" class="mention hashtag" rel="nofollow noopener" target="_blank">#pinball</a> <a href="https://mstdn.games/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> <a href="https://mstdn.games/tags/techgore" class="mention hashtag" rel="nofollow noopener" target="_blank">#techgore</a>

Kris\Slykaok, after a lot of fucking around and not nearly enough finding out I've finally got my DIY vidicon camera making images again! And they're… better?! They're definitely a lot sharper, but with increased bandwidth and sensitivity also comes increased noise!Luckily the noise does not seem to stem from the preamp itself, which is nice, but only shows up once the high voltage is turned on, so it's probably mostly from the pretty noisy switching high voltage supply and the general… well… lack of proper grounding and power supply stability and shielding and all of that. There is more than a volt of ripple on the 300V rail which probably isn't good…First image is straight from the camera, second one is the average of multiple exposures.<a href="https://pawb.fun/tags/Vidicam" class="mention hashtag" rel="nofollow noopener" target="_blank">#Vidicam</a> <a href="https://pawb.fun/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> <a href="https://pawb.fun/tags/Photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#Photography</a>

GusDo I know any Australian <a href="https://aus.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> nerds who could use a small IR reflow oven? Yours for cost of postage.This is a Qinsi QS-5100, purchased in 2013. Used only a few times, and probably not for ten years. I just fired it up and the heating element, fan, etc. all seem to work as expected - but it could use a thorough test at minimum.A lot was written about these ovens back in the day, particularly by Ian of Dangerous Prototypes.If, like me, you only assemble boards in ones and twos for prototypes then TBH you probably don't need this (I use hot air and a preheater). If you do frequent small assembly runs and can be bothered dialling the temp curves in (in theory a one-time process) then it may be of interest.

Within the first five miles I found one on the side of the road! It had been run over, which squished the battery, but otherwise works fine.

C.Soft switching fell out of favour after this period, too, because it could cause "tone suck". That's a real description; basically, guitarists complained that when their guitar was routed through the pedal to their amplifier, but the effect was disabled via soft switching, it would sound worse - its tone would <a href="https://mindly.social/tags/suck" class="mention hashtag" rel="nofollow noopener" target="_blank">#suck</a> - than when they plugged their instrument directly into the amplifier.With well-designed and manufactured effects circuits, and with reasonable <a href="https://mindly.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> in the guitar and the <a href="https://mindly.social/tags/amplifier" class="mention hashtag" rel="nofollow noopener" target="_blank">#amplifier</a>, this shouldn't be much of an issue, if at all. But there were (and are!) lots of badly-designed or badly-manufactured effects pedals out there, and plenty of guitars and amplifiers with stupidly-designed electronics. So it's entirely possible for tone suck to be a real thing - but as with anything audio-related, you would need a double-blind <a href="https://mindly.social/tags/study" class="mention hashtag" rel="nofollow noopener" target="_blank">#study</a> to determine how much of the effect was real, and how much of it was purely <a href="https://mindly.social/tags/psychological" class="mention hashtag" rel="nofollow noopener" target="_blank">#psychological</a>.So effects generally went back to "true bypass", with physical "stomp switches".There is a bunch of stuff in the schematic that exists only to implement the soft switching. We can strip all of that out, too.And if you remove both of those sections, you get this.3/x<a href="https://mindly.social/tags/tone" class="mention hashtag" rel="nofollow noopener" target="_blank">#tone</a> <a href="https://mindly.social/tags/suck" class="mention hashtag" rel="nofollow noopener" target="_blank">#suck</a> <a href="https://mindly.social/tags/ToneSuck" class="mention hashtag" rel="nofollow noopener" target="_blank">#ToneSuck</a> <a href="https://mindly.social/tags/bypass" class="mention hashtag" rel="nofollow noopener" target="_blank">#bypass</a> <a href="https://mindly.social/tags/TrueBypass" class="mention hashtag" rel="nofollow noopener" target="_blank">#TrueBypass</a> <a href="https://mindly.social/tags/StompSwitch" class="mention hashtag" rel="nofollow noopener" target="_blank">#StompSwitch</a>

C.This will be slightly <a href="https://mindly.social/tags/geeky" class="mention hashtag" rel="nofollow noopener" target="_blank">#geeky</a>, and probably only of interest to <a href="https://mindly.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> hobbyists and <a href="https://mindly.social/tags/guitar" class="mention hashtag" rel="nofollow noopener" target="_blank">#guitar</a> players. I happen to sit in the intersection of that particular <a href="https://mindly.social/tags/Venn" class="mention hashtag" rel="nofollow noopener" target="_blank">#Venn</a> diagram.When I was a teenager, having only been playing guitar for a few years, I owned a guitar <a href="https://mindly.social/tags/effects" class="mention hashtag" rel="nofollow noopener" target="_blank">#effects</a> pedal that went on to become legendary - the Boss HM-2 "Heavy Metal" <a href="https://mindly.social/tags/pedal" class="mention hashtag" rel="nofollow noopener" target="_blank">#pedal</a>. Its sound is still ubiquitous in metal.I don't have it any more. I think I traded it for an analog chorus, which was a seriously expensive pedal back then. Although I have other <a href="https://mindly.social/tags/distortion" class="mention hashtag" rel="nofollow noopener" target="_blank">#distortion</a> effects, I've missed it a lot over the years.Well, lots of hobbyists build their own effects. And the circuit schematics for many effects, particularly the classics, are available online. So like many others, I decided to build my own HM-2.This image is the schematic for the <a href="https://mindly.social/tags/HM2" class="mention hashtag" rel="nofollow noopener" target="_blank">#HM2</a>. It's not the most complicated pedal, but it's a league above something like an Ibanez Tube Screamer. As far as active devices go, it's got 6 <a href="https://mindly.social/tags/opamps" class="mention hashtag" rel="nofollow noopener" target="_blank">#opamps</a> and 10 <a href="https://mindly.social/tags/transistors" class="mention hashtag" rel="nofollow noopener" target="_blank">#transistors</a> of various types, along with a bunch of diodes for multiple types and stages of clipping, and the usual jumble of capacitors and resistors.
