I've been wondering for a while how I can contribute to the #oshw movement given I don't have much energy outside of work for doing additional electronic design work. It's occurred to me that if I don't have the energy to create stuff, maybe I can help others who do by offering to review designs.
DM me if you want a review of your #electronics project - I can review both schematics and #PCB layout. My only condition is that it must be #opensource.

Hey #feditronics , does it make sense to use the connection between the GND pin and the tab on a voltage regulator as a bridge? It would simplify my routing a bit.

I think this is universal, and applies in more situations than this.
You make a PCB, and you check it very carefully, every component on schematic and as placed, and all the design rule checks.
You double check.
You triple check.
You place an order.
The order is confirmed.
Now, when you look at the design, 5 different obvious errors jump out at you.
They were clearly hiding, before.
If you are really lucky, you can cancel the order and reorder, but usually it is *just* too late.

Well, I have ordered a board with a new TPS62933 design.

Quick test of the velocity sensitive buttons for the keytar.
I have to hold the 3d printed test rig in place so please forgive the shoddy note triggering. 😅 Overall it feels pretty good; there are 3 different velocity curves to choose from.

Just got one of my more involved Home Assistant integrations online. We added a pressure transducer to monitor the water pressure for our pressure tank (where the well pump comes in). We have an Olimex PoE ESP32 there already and I decided to custom design and fabricate a PCB (first time ever) as a hat for an ADS1115 ADC and connectors.
It works! So we can now monitor our water pressure in excruciating real time precision. Just because.

It wooooorks. Well, mostly.
A more clever me would have broken out the 5V line for USB power since it already has a 3.3V voltage regulator -- had to get another regulator for the breadboard to connect to my laptop. Also, finally figured out how to make my own bootloader variant and configure the microcontroller pins.
Everything seems to be working so far. However, 3 of the 40 hall effect sensors are giving me weird values/unresponsive. Perhaps maybe I damaged them during the soldering process?

I think I've finally finished the boards for the keytar. Unfortunately, I don't know of a convenient PCB manufacturer in the US that offers assembly. I can solder most of them myself, but the board containing 576 LEDs might be a job for a pick-n-place machine. 😅
I'm considering going through @aislerhq to have them made. Has anyone in the states tried them before? Guess I'm worried what the customs situation might look like. 😬 :boost_request:
More keytar updates soon!

About two and a half octaves of velocity sensitive keytar goodness. There will be four of these modules that can either operate together, as a single keybed, or divided into separate MIDI channels.

Finally getting into the CAD portion of the keytar project.
I guess this can be considered the guts of the "guitar body" for the keytar. The LED board will respond to the capacitive touch panel above it – hopefully indicating fader positions, which buttons are toggled on, virtual string strumming, etc. The beige looking panel on top is a cork gasket to protect the touch panel from the aluminum enclosure.
(Obviously the pins of the cartridge slot will be trimmed down and not magically colliding with the stuff above it. 😅 Still have to decide on the final location when I design the body.)

It is good to sometimes go back to the basics and hand assemble some prototypes. It took me about two full days to assemble and partially test these. When using the Pick and Place machine I can assemble about 1k units in that time 😭(it takes several days to set up the machine so it makes little sense for early prototypes, and I don't have them on panels anyways…) #microcontrollers #debugging #development #PCB #assembly #SMT

How good is the quality of that PCB you've just had fabbed? Turns out there are tests for that. (Medium sub required.)

Big win! I installed the #Turbokit on the #GEM #S2 and after some fiddling IT WORKS! I waited this moment since 1996 🥰 The #PCB was correct and the components were perfect, but it took a while to fix all the bad solder joints. Gosh, those 0402x8 resistor networks are SMALL and it took a while to learn to solder them properly (hot air and flux are your friends). Now, I only have to install the NiMh battery in a safe way. #electronics #sinthdiy #diy #music #Generalmusic #S3

Anyone know how these spring loaded clips are called that temporarily mount to through holes in a PCB?
I don't mean the PCB spring contacts that are used for connecting to surface test points
There was something that basically greps onto the inside of the through holes, makes contact and holds by friction using a spring that increases its diameter slightly. To remove it you just briefly pinch it. They appeared quite useful but I didn't buy them right away and now: gone?
