Default What's your first diy work?

I'm ending to build balanced zen line stage, my first project at all, never used a solder before, but in 2 days i've build it, for the line board i've used the original from Nelson Pass and for the regulated psu i've tried point-to-point wiring... ufff! But it was well done (by a multimeter point of view)

Not including a little sound effects maker that I put together as a wee sprout, it would be Nelson's Bride-of-Zen. I used it for a long while before recently converting it to a Bride of Son of Zen.

Well - my was some 37 years ago. The coil, diode, capacitor and headphones together with antenna and ground created AM receiver - that's how I became electronic designer

Well, if it must be audio related:

-a small FM emitter, from elektor, maybe 8 years ago. Never worked well (poor electret mic, and the tuning wasn't stable at all: moving your hand 10cm over the board would untune it)
-a szekeres headphone amp, 18 months ago (when I first came here)

Hi,

Well my first work was actually a 2 transistor FM “spy” transmitter. Was great fun at birthday parties of my parents

My first serious amp was a copy of a Quad 303 and then a 1969 JLH 15W amp which is still at my fathers workshop (he refuses to give it back )

Cheers

Default First audio project

My first audio project was a stereo amp for a record player. I used a matched pair of AD161/AD162 output transistors driven by a 741 op amp.

Those were the days

Back in highschool... studied about 5 different LM386 schematics and then put together one of my own that was a hybrid of all 5 to run off my car cigarette lighter with a CD player and some cheap speakers since the car only had an AM radio. Worked well enough, was pretty proud of myself until last year when I decided to look back into that project and found out that....
LM386's are single chip solutions... minimal external components required.

Default It's almost audio related....

...my first project was a sound to light system, which as a teenager was an excellent way of getting invited to every party going. It worked just fine until a friend's dad decided he'd tidy up the wiring in the light boxes and shorted all the outputs. Oh well...
