#breadboard

I designed a #SMD adapter board using @kicad and let @aislerhq manufacture them. They are for #SOT23 on one side and #SOT363 on the other side. They bridge the gap of a #solderless #breadboard, so they are perfect for #prototyping circuits or trying out new components - or as replacement for through-hole parts. I soldered a dual diode #BAV70 on one and a dual NPN/PNP transistor #BC847BPN on a second one to try them out. I'm satisfied how they look, although the white area for labeling is a bit small - I need a thinner pen for that.
You can find the shared project here: aisler.net/p/UTAGNLYX (trying out this feature, please give feedback if you use it).

the delivered boards, they came in panels of 20 each. You can see both sides, one of the individual boards has been broken out of the panel and lies above them with SOT23 side up, the panel beneath has SOT363 side up. the next panel below has SOT23 up, but is only partially visible at the top.
two of the boards with soldered components. the top one has a dual NPN/PNP transistor BC847 BPN, and the lower one has a BAV70 dual diode. the area for the label is a bit small, so they only have "847" and "A4" written. the two boards are inserted into a solderless breadboard, bridging the gap in the middle, so the pins can be accessed on either side.

I wrote an instructions for a simple way to make a phono equalizer that converts the output signal of an MM cartridge to standard audio signal.
It was made using an universal board printed in the breadboard wiring pattern.

One of the final modules for my #StackSynth project: the #noise generator. It outputs white, blue, and pink noise and uses a #3904 and a #TL074 with a lot of resistors and a couple of capacitors.
It is based on Moritz Klein's video: youtu.be/0yB_h_wFkh4
I prototyped it on solderless #breadboard and then designed the #PCB in @kicad and let @aislerhq manufacture them again. It turned out quite nice and sounds great.

the prototype on solderless breadboard. it's a bit messy and has lots of resistors scattered around.
the finished board from the top. the components are placed in a neat grid and look very orderly.

Finished #soldering. What I learned so far: l should clean between soldering #SMD components and #throughhole ones. I should leave enough space between the SMD components. I also dislike 0806 #resistors, better get some in 1206 size. The #capacitors were okay.
I tried it out with a square and a triangle wave as two inputs, connected through #potentiometers on a mini #breadboard and looked at the #oscilloscope

finished board with all components soldered in. two inputs and the power are connected.

Help.

I am going nuts.
I have a DC Power supply. I feed a PWM with that. I have two Mosfets, Drain and Source are in parallel with the PWM, but the gates:

1. Connected to Negative Terminal of the PWM. I can tune a LED (load) just fine (dim).

2. Connected to the Positive Terminal of the PWM. The LED lights constantly.

This should be the easiest thing in the book. Why is this failing? I even tried some pull-down R's (1k, 10k) to no avail.

My thought: Having a Pos-Gate Mosfet and a Neg-Gate Mosfet will turn one led up and the other down, and vice versa.

📢 Starting making something today!
🪛 Try your hand at making The Ultimate DIY 3220-Point Breadboard - a project that will have you creating a breadboard equipped with its own three separate power supply capabilities: a 12VDC power jack, bench-top power supply hookup, and an onboard 9V battery supply.

😎 This is a neat and handy project; one that's perfect for the individual who wants to make a serious electronics project at the beginner level.

can anyone tell me iof theres a specific name for the type of protoypying PCB thats in this picture, (the green one in bottom left) I've seen them refered to as gold finger PCB, but not sure. its to plug into cartridge port of dragon 32

I'm looking to get one in the UK so any suggestions where to get one a browse on amazon didnt get me much luck,but I may have been searching for the wrong thing

an electronic prototyping setup involving a breadboard, a perforated prototyping board (PCB), and several multicolored wires connecting components. Top right: A white breadboard with components like resistors and jumper wires connected to it. Bottom left: A green perforated PCB with many small holes, commonly used for soldering or prototyping. A row of pin connectors is visible on one edge of the PCB. Right side: A black microcontroller or electronic module with many connected wires. Across the image: Multicolored wires (red, orange, yellow, green, blue, purple, black, etc.) stretch between the PCB, breadboard, and the microcontroller.
