I was looking at how to build an octave per volt circuit for an analog synthesizer. I found an adjustable rectifier with no forward voltage drop. It sits in its own  vacuum chamber and can be controlled via feedback using the second diode next to it. They both share the same heat source. They are a glut on the surplus market, so there is yet to be a shortage of the remarkably affordable device. I present to you the Soviet 6H7B (6Х7Б-В) miniature double diode tube. It is soldered into the circuit with its own wires, saving the cost of its own socket that costs more than the tube. The second diode is placed into an adjustable circuit that controls the temperature of their common filament through feedback by measuring the second diodes' throughput. The adjustable feedback of keeping the diodes' common filament at the correct temperature will give its twin the right logarithmic forward voltage. The logarithmic curve of the diode is used by a log amplifier to convert the input of one octave per volt into a linear output some of the other circuity can understand. Keeping the diodes' filament at a much lower voltage and current than its specification sheet says it can handle will keep the tube working much longer, though it may drift in a person's lifetime. The lower Watts should cut back on noise from the tube. If we run out of 6H7Bs, we can switch to any number of other tubes with a common filament and more than one diode. Some company just might start making a 6H7B replacement tube, but they will probably sell them at boutique prices. If someone complains we are glorifying a commie tube, ask them "Then why are there so many on the open market? " I got mine from Ukraine.

I am trying to get serialplot working on a linux pc but have run in to problems. I downloaded the AppImage chmod to executable, and tried to run on Fedora 30. Failed. Couldn't find Qt platform plugin xcb. Adding "export QT_DEBUG_PLUGINS=1" and trying again yielded more info: can't load libqxcb.so: (/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var)". Tried again on Fedora 27, but failed with "QGtkStyle couldn't resolve GTK." After failing to get serialplot running on Fedora 30 or 27, I am at a loss as to how I should proceed.

You don't need ps2 to uart converter to attach a keyboard, you can directly connect a keyboard micro it requires a timer and an interrupt enabled pin. If you want can help.

I tried it out and I like it. It's bare bones but it's easy enough to use that I can easily sneak it in my workflow.

Good job with this!

It only pulls projects from 2014 till 2017 for me :D the last one is the 433MHz MQTT thing, I presume it's capped somehow?

And after creating and posting a new log, the app crashed. Also the fire emoji was converted to a question mark.

Rocking a Samsung S6 edge, Android 7.0 - cool stuff though!

A solder oven controller, written in Qt so I can debug it on my laptop over serial.

On the phone it uses bluetooth.

It helps to see a picture of the oven on the background so you're using the correct PID settings.

Since it's a phone it would make sense to just snap a picture of a new oven in the app before calibration.

Nice! I've always wanted a Hackaday app and I'm glad to see movement in that direction. I'd love to see a full-fledged app which lets you view and search projects, post comments, edit projects, etc.
