I think perhaps that the manufacturer's "typical application" circuit is missing a few things...

Ha, well, first time I've ever run into a electronic #schematic which pertains directly to #beekeeping. The #Apidictor (used to attempt to detect if there is or is not a #queen in a hive!) https://www.beesource.com/threads/apidictor.365768/

Are there any #guitar #wiring #diagram #schematic or #pickup installation people here? I need #help with finding a wiring diagram for a Seymour Duncan #HSH setup with 1 volume and 1 tone pot and a 5 way import blade switch. Both pots are push/pull, each working as a coil split for just one of the #humbuckers

It's for a Brian Moore i1 (no piezo or midi). Nobody seems to have a schematic/diagram for this thing online.

Don't think I've shared this very nice review from Igloomag for my latest EP here.

Some 13 years later, I've done a little revision to the Modutronic Messmaker circuit schematic available from the FSA website. I think this would make a good "beginner" build, and this new revision removes some complexity (and cost). The original version is also still available from a link on the page.

On m’a donné à réparer un vidéo projecteur Sanyo PLV-Z4 avec le manuel de l’utilisateur. Rien d’interessant dedans par contre le manuel de service est top, il contient :
Le démontage de toutes les pièces, la liste de toutes pièces, les bordviews, diagrammes de démarrage, diagrammes de fonctionnement (les bus vidéos), comment réaliser le calibrage complet, un guide de recherche de panne avancée..
Bref un sans faute, ça fait plaisir.

@kicad #KiCad is really nice for designing the #schematic and board layout, even for such #perfboards.

My friend asked if i could make him a kill-switch, so i drew this. a digitally controlled three-channel mute/anti-mute. posting here just because.. any glaringly obvious mistakes? i hope not... #electronics #schematic #circuitdraft #CMOS #logic

I published a new release of #schemdraw today, the #Python library for drawing electrical schematics, flowcharts, and state diagrams via code. This update is mostly little bug fixes and enhancements that have been collecting for a few months.

Happy circuit drawing!

Was laying out the #kicad #schematic for #muvco and it started to seem too pedestrian.

Went back and realized I had been using the #pcm5102 wrong and it does indeed do exactly what I originally wanted.

Now making a waveform generator instead of using the dds #ad9833. Much more flexible in shape and can be semi-polysynth ("chordal #synth"?) #synthdiy

Can now generate a perfect 5th in 260us! In mostly-unoptimized #micropython! Just dyads still--need to generalize to larger chords + diff shapes.

Did I mention that I copied the original schematic? Apparently I copied it a bit too well. Actually, 20 year ago me forgot to go back and update the schematic after finding a bug. I fixed the original board, so now I have to fix the new board. Current me also went back and updated the #schematic this time. #hardware #modwire #PCB

(Except that the last line of this picture is apparently controversial, as it shows an #Ossetian #pie, which Ossetians don't consider to be a type of a Khachapuri; it being the staple of local #culture, and traditional (Pagan) #religion.

These are the insides of a #Philips DVP630 #DVD player. It has been broken for a few years and was given to me.

There are 4 boards inside. From right to left is the power supply (directly from mains), the main board, and a board for #SCART output. On the bottom is the front panel board which has standby/play/pause/etc. buttons and a small display. On the left there's the DVD reader (with a long jammed DVD in it).

The player did not turn on. After some research I found that on this model this may happen due to a bad #capacitor, C316 on the power supply board. You can see it slightly bulging in the picture (not the best angle to see it, sorry).

This is a 1000 μF 10 V capacitor. I did not have 1000 μF capacitors so I didn't try to repair this for a long time.

Recently I wanted to watch some DVD and so I thought "okay, let's see if I can repair the DVD player". So the other day I went to buy some 1000 μF 16 V capacitors. 16 V instead of 10 because I suppose this capacitor normally fails because a slightly larger voltage one should have been used in the design. Hopefully a slight larger one will last longer.

The repair was very easy, just disconnected the board, desoldered the bad capacitor, soldered the new one. Parts cost was 15 cents.

I also found the #schematic for the boards online. Capacitor C316 is related with the circuitry that ends up producing a 5 V source. I measured this after I replaced the capacitor and reassembled the player and sure enough 5 V were there (shame I didn't measure this point prior to the repair, but I didn't want to get shocked due to a large charged capacitor in the supply).

The moment of truth followed, tried to power the player on and it worked!! DVD spins, display says "loading", then "play" then starts counting seconds.

Now to test the player. The outdoors are analog. To my dismay my TV only has HDMI 🤦‍♂️

Tested on my parents TV which has AV input. Used a SCART to AV cable. No image detected 🙁 what a disappointment. You win some, you lose some.

A few days followed. I had the ideia that maybe the SCART board is bad, that maybe using the AV output directly would work. I didn't have an AV to AV cable at hand though. Then the other day my girlfriend found one.

Yesterday I tested the player's AV output. And it worked! The player works baby!!

TL; DR: I managed to repair an old DVD player. SCART does not work but AV does. May investigate this in the future.

I built a super simple 4 channel mixer in #circuitjs, then drew it up as a #schematic in #kicad plus the extra bits like power connections and #audio jacks.

What I should do: #Breadboard from the schematic to check it.

What I will probably be unable to not do: Jump right to the #pcb and order it.

Draw electrical schematics using Python code and Schemdraw!

import schemdraw
from schemdraw.elements import Resistor, Capacitor, SourceSin, Line
with schemdraw.Drawing() as d:
d += Resistor().label('R1')
d += Capacitor().down().label('C1')
d += Line().left()
d += SourceSin().up().label('$v_{ac}$')

I love how the extra pins are not sequential either.

@Ricardus My search for a schematic has so far been unsuccessful. It's a cheap old keyboard, SIEL MK610, pretty obscure apparently. Hashtags maybe?
