Dan Maloney and I were talking on the podcast about his memories of the old electronics magazines, and how they had some gonzo projects in them. One, a DIY picture phone from the 1980s, was a monster build of a hundred ICs that also required you to own a TV camera. At that time, the idea of being able to see someone while talking to them on the phone was pure science fiction, and here was a version of that which you could build yourself.

Still, we have to wonder how many of these were ever built. The project itself was difficult and expensive, but you actually have to multiply that by two if you want to talk with someone else. And then you have to turn your respective living rooms into TV studios. It wasn’t the most practical of projects.

But amazing projects did something in the old magazines that we take a little bit for granted today: they showed what was possible. And if you want to create something new, you’re not necessarily going to know how to do it, but just the idea that it’s possible at all is often enough to give a motivated hacker the drive to make it real. As skateboard hero Rodney Mullen put it, “the biggest obstacle to creativity is breaking through the barrier of disbelief”.

In the skating world, it’s seeing someone else do a trick in a video that lets you know that it’s possible, and then you can make it your own. In our world, in prehistoric times, it was these electronics magazines that showed you what was possible. In the present, it’s all over the Internet, and all over Hackaday. So when you see someone’s amazing project, even if you aren’t necessarily into it, or maybe don’t even fully understand it, your horizons of what’s possible are nonetheless expanded, and that helps us all be more creative.

Keep on pushing!

In the Microchip tinyAVR 0-series, 1-series, and 2-series we see Configurable Custom Logic (CCL) among the Core Independent Peripherals (CIP) available on the chip. In this YouTube video [Grug Huhler] shows us how to make your own digital logic in hardware using the ATtiny CCL peripheral.

If you have spare pins on your tinyAVR micro you can use them with the CCL for “glue logic” and save on your bill of materials (BOM) cost. The CCL can do simple to moderately complex logic, and it does it without the need for support from the processor core, which is why it’s called a core independent peripheral. A good place to learn about the CCL capabilities in these tinyAVR series is Microchip Technical Brief TB3218: Getting Started with Configurable Custom Logic (CCL) or if you need more information see a datasheet, such as the ATtiny3226 datasheet mentioned in the video.

A tinyAVR micro will have one or two CCL peripherals depending on the series. The heart of the CCL hardware are two Lookup Tables (LUTs). Each LUT can map any three binary inputs into one binary output. This allows each LUT to be programmed with one byte as simple 2-input or 3-input logic, such as NOT, AND, OR, XOR, etc. Each LUT output can optionally be piped through a Filter/Sync function, an Edge Detector, and a Sequencer (always from the lower numbered LUT in the pair). It is also possible to mask-out LUT inputs.

In the source code that accompanies the video [Grug] includes a demonstration of a three input AND gate, an SR Latch using the sequencer, an SR Latch using feedback, and a filter/sync and edge detection circuit. The Arduino library [Grug] uses is Logic.h from megaTinyCore.

We have covered CIP and CCL technology here on Hackaday before, such as back when we showed you how to use an AVR microcontroller to make a switching regulator.

[Bozza 2025-09-08]
Dopo il 14 Ottobre 2025 #microsoft non rilascerà più aggiornamenti di sicurezza per il sistema operativo #windows10.

Nell'ottica di minimizzare l'acquisto non necessario di nuovi dispositivi e quindi ridurre il pattume ('sto pattume è ad alto impatto ambientale), offro supporto a #Torino a chi dispone di un PC non compatibile all'aggiornamento a #windows11 o a chi vorrebbe migrare a #linux indipendentemente dalla fine del supporto di Windows 10.

[sto valutando l'idea e la possibilità di riuscire a farlo]

Il mio supporto ed il mio aiuto sono offerti a titolo #gratuito, alle seguenti condizioni:
- nessun obbligo (il mio tempo libero è limitato, come il vostro... 😅); se ci fossero molte richieste, cercherei di smaltirne il più possibile secondo le mie possibilità; linea guida: chi prima chiede, prima viene contattato; eventuali cambi di priorità di stampo etico a mia discrezione... 🏴‍☠️
- non sono responsabile dell'eventuale perdita dei vostri dati (sarebbe vostra cura creare un backup prima);
- non offro qui servizio di assistenza tecnica SW o HW, al netto delle necessità dell'installazione di Linux in oggetto.
- [...]

Eventuali offerte volontarie verrebbero devolute ad associazioni/iniziative #foss locali, da identificare.

Inizio stimato dell'attività: 01/07/2025.
--> Chiarire il tipo di utilizzo del pc prima della migrazione (ufficio, navigazione, gaming, multimedia/audio/video, programmazione, ecc...);
--> Fatevi backup dei dati prima;

A common ratchet from your garage may work wonders for tightening hard to reach bolts on whatever everyday projects around the house. However, those over at [Chronova Engineering] had a particularly unusual project where a special ratchet mechanism needed to be developed. And developed it was, an absolutely beautiful machining job is done to create a ratcheting actuator for tendon pulling. Yes, this mechanical steampunk-esk ratchet is meant for yanking on the fleshy strings found in all of us.

The unique mechanism is necessary because of the requirement for bidirectional actuation for bio-mechanics research. Tendons are meant to be pulled and released to measure the movement of the fingers or toes. This is then compared with the distance pulled from the actuator. Hopefully, this method of actuation measurement may help doctors and surgeons treat people with impairments, though in this particular case the “patient” is a chicken’s foot.

Blurred for viewing ease
Manufacturing the mechanism itself consisted of a multitude of watch lathe operations and pantographed patterns. A mixture of custom and commercial screws are used in combination with a peg gear, cams, and a high performance servo to complete the complex ratchet. With simple control from an Arduino, the system completes its use case very effectively.

In all the actuator is an incredible piece of machining ability with one of the least expected use cases. The original public listed video chose to not show the chicken foot itself due to fear of the YouTube overlords.

If you wish to see the actuator in proper action check out the uncensored and unlisted video here.

Renata Morresi:
Dunque, con calma, vagliando ogni sintagma: ieri notte, in acque internazionali, dei #droni da guerra, forse mandati dal governo di #israele , hanno attaccato una nave con #aiutiumanitari diretta verso un luogo dove non c'è più cibo, acqua, elettricità, medicine, ecc., #Gaza . Ripeto: AIUTI UMANITARI - PER GAZA - BOMBARDATI - DA DRONI - IN ACQUE INTERNAZIONALI. Quando apriremo gli occhi su quello che stanno facendo il criminale #Netanyahu & i suoi complici? Per quanto tempo ancora potremo assecondare questo scempio? Potremo dire che non sapevamo? Che non arrivavano immagini o notizie? Che non conoscevamo i #genocidi ? Né i #criminidiguerra ? Come faremo a parlare di umanesimo? Di studiare la storia per non ripeterla? Come faremo a credere ai 'valori cristiani' o 'occidentali'? All'uguaglianza e all'equità? Al progresso e alla civiltà europea? Come faremo a guardarci allo specchio?

#genocidio

Scommettiamo che, tempo sei mesi, anche del prossimo papa si dirà (o meglio, i suoi seguaci diranno) che è un papa che piace ai credenti e ai non-credenti?

A me i papi non piacciono mai (*) ma probabilmente rappresento una parte minoritaria dei non-credenti.

(*) il che non vuol dire li consideri tutti dei pendagli da forca ma se facessi la lista dei cento terrestri che mi piacciono di più dubito ci finirebbe dentro un papa.
