#smd

Finished #soldering another #StackSynth #diysynth module, an important one: the #VCA - together with the ADSR, it makes the output sound much better.
Again, boards were manufactured by @aislerhq and they look nice.
I noticed that I didn't have any 2MΩ 0805 #SMD resistors, but found a couple of larger 1206 2.2MΩ ones in my recycle bin. They don't fit perfectly, but should do until I have the proper ones.

bottom of the finished board. the SMD components are visible.

closeup of the two larger 1206 resistors (R29 and R11). the top one is a bit crooked.

As announced, I finished the buffer today. Also, I soldered all #SMD components to the #VCO board that I already had. The two missing resistors will follow when they arrive.
It was fun and went better than my previous attempts, since I used a smaller tip.

the finished buffer. the two inputs and one output are connected. the LED for the second input is lit, since there is some voltage.

the VCO board with almost all SMD components soldered. only R2 at the right and R8 at the top left are missing.

Three new boards for my #StackSynth arrived from @aislerhq yesterday. They are buffer, #ADSR, and #VCO. The VCO is the first with #SMD components on the bottom side. Two resistor values are missing in my SMD collection: 30k and 68k. I already soldered the ADSR and tested it. The buffer will follow tomorrow.
#diysynth #soldering #synthesizer #envelopegenerator

my parts boxes for the new boards. left has the components for the ADSR, right for the buffer.

the parts box for the VCO. it is the first StackSynth board with SMD components. two resistor values are still missing.

the finished ADSR board. it is powered and has a cable in the gate. the LED is lit, indicating the output being active.

capture of the output of the ADSR. you can clearly see the four stages Attack, Decay, Sustain and Release.

Today's work: Some #smd tapes finally stored properly in magazines with proper labels and #pdf417 codes for fast access to #PartDB mounted on top of a 3d printed DIN rail. Turned out really well!

SMD magazines in red and green with labels on top and front in different sizes.

Foreground: a diy and chip reel holder for buying, storing, and dispensing smds in bulk. It has 13 reels on it, black, white, paper, plastic, active, and passive components. Background: lab inventory process continues on screen in helix. A timer sits on the desk counting down pomodoros.
