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

Second exercise in PCB design with #Kicad: a super simple #eurorack overdrive module (non-inverting soft clipper using LEDs). Essential features missing (gain) and probably tons of obvious mistakes but it's my first complete module. #synthdiy #electronicsDIY

The final section of the magazine was often dedicated to projects sent by readers. They usually only provided the schematic and a brief description of the circuit. It was usually a favourite of mine as it was very diverse and interesting. #ElectronicsDIY #NuovaElettronica

After a forgettable article about magnetotherapy, the next project is a 4A DC power supply, with a switchable voltage output from 5V to 15V. Based on a nice toroidal transformer, it’s a conventional linear design. It was meant to use car radios at home, as most of them were removable so they weren’t left in the car, as they were stolen very frequently. I like the style of the box! #ElectronicsDIY #NuovaElettronica

Then, the “pièce de résistance”, i.e. the Delta computer, that was a nice Apple 2e clone. The guy in the top picture by the way recalls me my electronics professor when I was at the university. @hkz rebuilt it from scratch by redrawing all the schematics in KiCad as well as all the motherboard with minor modifications. He could run my text adventure games on it and I am in awe. #retrocomputing #Apple2 #NuovaElettronica #ElectronicsDIY

The next two projects are a guitar preamplifier that boosts the 3kHz to 6kHz frequency band and a junction tester equipped with a beeper. The latter may be useful, indeed, as the sound is different when the junction is good or in short circuit and you just have to keep your eyes on the circuit you are testing. Of course, there’s no sound for an open circuit. #NuovaElettronica #ElectronicsDIY

Then, we find two other blinking lights projects. The first one is an interesting two-transistor design that used an uncommon circuit. The second one is again a strange Christmas light project based upon a SN76477, that is in reality an audio synthesiser IC they must have had in stock. #NuovaElettronica #ElectronicsDiy

The second project of the #NuovaElettronica 104-105 from 1985 was a simple test oscillator for CB radio at 27 MHz that could be modulated by an audio tone. They used a 74LS266 quadruple XNOR in this project and in another one a few pages after. Probably they had a large stock of them to sell in the kits? #electronicsDiy #electronics

BTW, if you want to test the release candidate of #FidoCadJ, do it now! We are planning to release the stable version as soon as we get enough feedback and we are confident that enough bugs have been ironed out. We would like to have a feedback also about the release process, too. #opensource #ElectronicsDIY #Electronics
