In the process of stripping wires, a wire stripper I have used for 3 decades bit the dust. The grabber piece broke. Cheap, and fairly durable, considering.

I resorted to the old-fashioned method. A cutter on needle-nose pliers.

I'm at the point where I have to configure the inverter. Everyone is powered up. No smoke. No flames. No unusual messages.

The comms part is confusing because I have 2 Asian translations competing to make sense, and there are several protocols I could use. I hope to get the box recharging tonight.

It's like having a rack from the ISS in my place, but we're good.

I'm almost done setting up the DIY battery & inverter, or to put it another way, my overly-big UPS.

After reassembling the battery pack & verifying it worked, I've connected it to the inverter via battery cables, plus a repurposed indoor/outdoor plug cable to get power to the inverter from a wall plug, and a repurposed 6-outlet surge protector for the output. That part I may wind up rewiring for a longer cable, but it should do for what I mostly need it for.

I have to change some settings on the battery's BMS, then connect the two up. Hopefully, everyone communicates and voila.

It will have to cycle a few times for the batteries to balance.

I'm taking a break.

A manufacturer handily made a ring, attached in 4 spots, inside of another ring. This was so that they could use the same run of sheet metal for both sizes of cable that the device is made for. Naturally, ha ha, I needed the inner ring removed.

In sheet metal. Without enough space to fit decent cutters.

The last time I tried this with small cutters, the sheet metal had its way with the small cutters, and ruined them, but stayed put.

I had to use a custom hacksaw (the blade sticks out a couple of inches) and needle nose pliers to get it off. It? There were 2 of them.

It provided me with 2 keen new labels for my guitar cases, though.

Idea: use 6 GPS modules in parallel to get a more precise (averaged) position.

Version 2 of the #eurorack overdrive module:

- Placed filtering caps closer to op amp.
- Schottkey diodes to protect against reverse polarity.
- Tip normal of input jack connected to ground to avoid noise/hum/interference when nothing is plugged in.
- Unity gain for unused op amp.
- More compact design.

I'm running out of ideas for what to improve. The next version will have drive, tone, and volume controls. #synthdiy #diy_electronics #electronicsDIY

Everything is upstairs. Yay!

I carried more than 235 pounds of stuff uphill 7 feet. My legs want to know why I even attempted to carry a linebacker.

Today was tear-down and get it upstairs day. Tomorrow is reassembly and find out if I broke the electronics day. Whee.

Now the clock has a menu system, using the rotary encoder and OLED. Mostly nonfunctional so far, but it can switch between 12 and 24 hour modes, and re-set the time from NTP if it ever gets far off (probably not).

No video of that because the screen is too damn small to see on a video. I did find the larger OLED I thought I had, but it turns out to be only semi-functional. Need a new one.

ok, I think this one came out quite well, I'll do a - little - video on mastadon, I think its worth the space. So, its got programmed waypoint lists for forward/reverse/left/right/stop that it interpolates the points of. The led indicates a joystick position update, the joystick sends out regular updates even with no signal changes that act as a dead-man detector to stop the robot if you lose signal. #robotics #robot #robots #hobby #diy_electronics #diy #52robotsIn52weeksChallenge

I made an analog modular #synthesizer in a briefcase.

OK, now the encoder does a thing.

#electronics #diy_electronics

Clock's got an OLED display now! Ignore the half disconnected encoder, that's next.

Help needed: I am looking for a cheap THT magnetoresistive sensor that I can use as or in a voltage devider to make an LED turn on when in proximity to a magnet. Reed switches in my experience need the magnet to be very close.
I want to make something similar to this but without any microcontroller: https://www.youtube.com/watch?v=a1gSrGlK7j8
I did some Digikey research and AI chatting but it still feels like guessing.
Anyone having experience with components like this?

My earrings are back in stock! Just need to put them together. You may have seen them at #39C3, but I quickly ran out there.

You can buy a pair in person at #FOSDEM (no shipping!), or order them online:

Stack of 10 PCB panels, 6 earring PCBs each. They're on a desk, ready to be programmed.

Is there a simple tool (on Linux) to DRAW a circuit board, not design it? I just want a grid and be able to draw traces. I don't want to explain what a Seeed XIAO is or what my OELD screen looks like (yes, KiCad drives me crazy and I'm too old for this shit. This close to draw it in Inkscape).

Is there an equivalent of JLCPCB or PCBWay in Europe? (ideally, France) ? #electronics #diy #diy_electronics #embedded

Paper bags and color-changing RGB LEDs are a great combination 😍 So simple to make a lampshade for my Book Lamp project but the same process can certainly be used for other light-up projects.

It's still a clock, but now it also plays music. Or ambient sleep sounds, if that's what's on the SD card. Needs a serial monitor to control the sound playback at the moment. There'll be buttons eventually and probably a knob and OLED display.
