#breadboard

I'm looking for #opinions from #electronics #hobbyists or professionals.

When I'm using a #solderless #breadboard to prototype circuits, resistors can be frustrating. If you just keep re-using the same well-worn ones that look like a pretzel, you have to leave the leads long for the unknown next place you want to use them, and you can accidentally short something else against the leads.

Over the years I've frequently thought "Someone must make #jumper wires with inline resistors so they're easy to reuse", but I've never seen them for sale. [1]

So I made a bunch. And wow, it's labour-intensive to make them well. That explains why no-one's selling them.

Would other people be interested in buying and using these? Anyone can make them, but a lot of people would rather use their limited #hobby time to make their projects, not make things they need to make their #projects.

I've reduced the amount of time to make them and will keep trying, but I would have to charge at least US $30 for a pack of ten. There are ways to reduce it further, but they require a significant investment in equipment, so I'd have to be selling quite a few.

I make them with good materials - silicone 26AWG #wire for flexibility, name-brand 1% metal film #resistors, total length 24cm.

Would anyone want these?

[1] Closest thing I've found is dfrobot.com/product-1438.html but they're rigid so you need to use an additional wire anyway if you're not connecting exactly that distance through clear space.

For anyone who's curious, here's some crappy photos of the two boards I made. They're divided up differently than the original in mine, the "volume board" (a better description would be distortion and tone controls) includes the opamps 3a, 3b, 2a, and 2b, plus their surrounding components as well, in addition to everything inside the double lines. Even so, that board is a lot sparser than the "main" board.

I got uploading to a SRAM working from an Arduino Nano! I have also tested properly resetting the 68008 from the Arduino and changing the pins to pull up. I should probably throw together a tiny bootloader and put a 512K SRAM on instead, and I think perhaps a SPLD or CPLD might replace the mess near the RAM more elegantly - a couple of daisy chained ATF22V10s might work well! It all seems stable at ~6Mhz despite being on a 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).

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.

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
