Game Boy Becomes Super Game Boy With A Pair Of Pis



For the Nintendo fanatics of the 90s, the Super Video Game Child was an essential cartridge for the Super Nintendo which permitted players to play Video game Child video games on your television. Not just did it enable four-color dot-matrix video gaming on the cinema, yet it allow you play those preferred Video game Child titles without investing a lot of money on AA batteries. While later handhelds like the PSP and even Nintendo Change have the ability to outcome video clip straight to Televisions uncreative, the initial Video game Child required handling aid from an SNES or, as [Andy West] reveals us, it can also get that help from a modern microcontroller.

The added handling power in this instance originates from a Raspberry Pi Pico which is little sufficient to conveniently fit within a benefactor NES instance as well as likewise effective sufficient to deal with the VGA straight. For video clip information input, the Pico>is attached to the video clip pins on the Video game Child’s major board with a degree shifter. The major board is likewise attached to a 2nd Pico which takes care of the controller input from an NES controller. Some expensive conversion required to be done at this moment since although the controller designs are really comparable, they are takes care of by the corresponding gaming consoles entirely in a different way.

With every one of the technological job greatly off the beaten track,

These consisted of making certain the power switches, standing LEDs, as well as reset switch all operated, as well as recovering the NES instance full with some customized” Video game Individual” graphics to match the initial layout of the Video game Child. We compliment using initial Video game Child equipment in this develop also, which also made it feasible for [Andy] as well as his other half to play a neck and neck video game of[Andy] Dr. Mario with a web link cord with one more Video game Child. If you’re searching for an easier method of using initial equipment without melting an opening in your purse purchasing AA batteries, have a look at this Video game Child reconstruction which utilizes a Lithium battery rather.(* ) Many Thanks to

555 Teardown Isn’t Just A Good Time, It’s To Die For




It appears just suitable that warm on the heels of the verdict of Hackaday’s 555 Timer Competition that [Ken Shirriff] articles a silicon die teardown of a very early variation of a cyberpunk’s preferred chip, the 555.

A Tiny Sight Of the 555 Pass Away

Beginning with a secret chip from January 1973,

meticulously fined sand down the bundle to expose the die, which he considered to be a 555 timer. Why really did not they understand it was a 555 timer to begin? Due to the fact that the bundle was not noted with “555 “however instead a few other marks that you can see in [Eric Schlaepfer].the blog post Along with an excellent description of just how the 555 operate in basic,(* )has actually taken a tiny consider the 555 die itself. The schematic of a 555 is quickly offered, and also

determines not simply areas of the die however specific parts. He goes better yet by clarifying just how the PNP and also NPN resistors are built in silicon. There’s additionally a good and also succulent little bit of understanding right into the resistors in the IC, however we will not ruin it below.[Ken] Make sure to reveal your love for the champions of the 555 competition, or at the minimum take a look at the job that took the quit area:[Ken] that you do not require a microscopic lense to see within.

555 timer

Congratulations Winners Of The 555 Timer Contest!




In some cases the very best motivation is constraint. The 555 timer does “one point”– contrasts a voltage to a pair limits and also outcomes a signal as necessary. It’s 2 comparators, a voltage ladder, and also a flip-flop. As well as yet, it’s one of the most marketed solitary chip of perpetuity, commemorating its 50th birthday celebration this year! So when Hackaday runs a 555 Timer Contest, cyberpunks of all red stripes bring out their ideal job to reveal their love for the Little DIP That Could.

The Victors

By far the favored entrance was the Giant 555 Timer by[Rudraksha Vegad] Each of our courts ranked it in the leading 5, and also it took leading honors two times. On its face, this is a straightforward “large 555 in a box” develop, however take a look under the hood. Each sub-module that comprises the 555– comparators, flip-flop, and also amplifier– are made from restored distinct components in real breadboard style, soldered to brass nails inculcated timber. As an output, it’s a great item of woodworking, however as a procedure of production, it’s a masterwork in recognizing the 555 at its inmost degree. We need to all make one!

The Menorah555 is a straightforward style with some extremely wonderful dress up its sleeve. Maybe the prettiest of which is drawing the main candle light out and also lighting the others with it– a technique that entails a supercapacitor and also reed buttons. Each of the candle light illumination circuits, nevertheless, make use of a 555 timer both for its designated objective of supplying a timed power-on reset pulse, and also an additional 555 is utilized as a straightforward flip-flop. It’s a glossy style, and also an excellent customer communication.

The Cyclotone Mechanical Punk Console Sequencer is a revolving tower of circuit sculpture and also noisemakers. This set looks fantastic, is extremely well recorded in the video clip collection, and also makes use of a billion creative little methods in the process. The 555’s duty? Each of the 4 degrees is the traditional Atari Punk Console circuit.

All 3 of these jobs win a $150 buying spree at Digi-Key. That’s a great deal of timers!

Hello There Globe!

You had one job– blink an LED with the 555. [Sami] made a PCB of an Audi e-tron for a leaving coworker. What can we state? The LEDs blink with 555s, and also the board looks snazzy.

Data Transfer Buster

Ends Up that you can make a4 MHz radio transmitter out of just two LMC555s (They’re the rapid ones.) Undoubtedly, the circuit’s just semiconductors are both 555s. One produces the service provider regularity, and also the various other just inverts the signal. Both of them in tandem kind a push-pull amplifier, for “optimum” power. 4 MHz with a 555 oscillator isn’t negative!


Among the strangest hacks, hands-down, is theAccordeonator It’s constructed of a CD drive, and also drawing the CD sled in and also out transforms the drive electric motor, which is utilized as a generator to power the entire circuit. 7 switches attach up timing resistors to the 555, that makes the songs. Really amazing!

Should Not Have Made Use Of a 555

If there are times when you should have, there must likewise be times when you should not, right? For example, you most likely should not make use of 555s as stepper electric motor chauffeurs, or as counters, in thisleaping-frog LED sculpture A 555 most definitely does not have the specific temporal resolution needed to glitch an STM8’s read-only protection bit, right? Absolutely you would not bit-bang the DMX512 serial protocol or make a serial ADC with a 555? As well as if you should not make use of a 555, does it count if you turn an ATTiny85 into a drop-in replacement?

This classification really did not dissatisfy, and also we’re not amazed. Inform Hackaday viewers what they can not do, and also they’ll do it!

Art for Art’s Purpose

Ultimately, our courts actually suched as CS 555, a completely circuit-sculpture distinct 555, and also the Spirit of the ’62 Rambler Nixie Clock which stimulates an old cars and truck’s dashboard as if driven by a macabre pressure. Naturally it’s a 555.

WTF Honor

We truthfully really did not understand that we required a respectable reference classification for making your very own 20-pin 555-timer based silicon, however obviously we did. [Adrian Freed] has a pair of new 555-based IC designs that consist of various other functions on-chip: one with 8 outcome barriers and also a counter, and also an additional with the intestines of a linear-feedback change register inside. His trial instance? Blinking a bunch of LEDs, normally. We would certainly like to see even more information concerning this task in the future.

… and also Even More

Congratulations to all participants in the competition! You need to actually take a while to surf all of the entries, and also not simply those that reverberated most with us. Since that recognizes, you may simply locate on your own stranded on a desert island, with just a dog crate of 555s available, and also require to rebuild contemporary culture.

Many Thanks once again to our enroller Digi-Key for the rewards and also the assistance!

Drill Does Well In Double Duty As Well Drilling Drill




There are a lot of approaches readily made use of to birthed an opening right into the ground for drawing out alcohol consumption water, as well as the all call for large loud tools. However what happens if you simply desire a little well? Do you truly need to hire the large weapons? [The Working Group on Development Techniques] is a trainee organization at the College of Twente in the Netherlands that receives the video below the break that some easy homemade components as well as an effective hand drill are rather sufficient to do the work!
