A controller with a scroll wheel, you say?

Well this is a little funny. Yesterday I posted the first part of a series of post on the fine details of how computers work, mentioning how I've been looking into this as part of a personal project I've been working on, and today I wake up to see Masahiro Sakurai posting a youtube video lamenting the lack of... this exact thing I'm working on.

Apologies for how much cat hair is in this photo, that's a bit of an occupational hazard, but this here is a photo I took back in September when most of the parts I had to order were in for the prototyping of this thing:

That's a really bad MS Paint mockup, but yeah. I'm designing my own game console, and one of the key features is a big ol' scroll wheel right in the center of the controller. Another is that I'm planning to just put all the designs of the circuit boards and 3D printer files for the casing/buttons up online for free, making it this totally open DIY thing where anyone who's a big enough nerd can just make a couple downloads, order some dirt cheap components, and build their own copy of the system (or people with better setups than me can build and sell them, whatever). So I'm not super worried about anyone stealing my ideas or whatever, but I WOULD like to establish a standard and all that, and figured it was worth noting that this is something I've been slowly working towards for like a year or two now, and didn't just get the idea from this video:

youtube

But yeah, now that the idea's out in the public consciousness, here's the plan for the controller (that I was planning to keep under my hat until I had a working prototype and some demo software sometime next year).

First off, the plan is that this is to be the standard controller for a whole console I'm also plucking away at designing, which is a bit more ambitious of a project, so I figure I might as well make it compatible with something that's already out there. So specifically, I'm designing this so that you can take one, plug it right into an SNES (or with a different connector at the end, an NES, because turns out they use the exact same input handling standard and it's just the shape of the plastic on the end that differs), and have it just work. Or mostly work anyway. I'm hoping I can process a signal out of the scroll wheel in a way that it either just needs the 3 extra bits of the input signal I don't have buttons for in my design (more on that later) or failing that, I can get it to output the same sort of signal as one wheel in the SNES mouse, which just rides along the second data line very few things use. I think that plan might break multitap compatibility and require an extra chip on the controller PCB, but it would leave this slightly more compatible with existing games on the same hardware. I might also do something weird with the button mapping to be sure NES select is on a shoulder and it works right out of the box with that whole library.

Working out exactly how to handle signals from the scroll wheel happens to be the point I'm currently stuck on by the way. I got this baggie full of rotary encoders for just a few cents which... almost fit in my first draft 3D printed wheel housing, but I have NO documentation on them, not even a part number/manufacturer besides "H-9," the pins don't fit a breadboard, and I've kinda been scrambling for rent so I can't afford a nice multimeter or oscilloscope to poke around with. Plus again I need to redesign this wheel print to even get it to spin right, and... this was a gift from a friend with a printer who is Not Local. Solvable problem, just needs more time and/or outside expertise.

But yeah, once I have those kinks worked out, it should be easy enough to get a custom board design made, replicas of end-cap of the controller cord are another problem easily solved by ordering a 1 dollar part or 3D printing something. The actual cord might be tricky since I don't know where you actually order something like that from, but it should be easy enough for anyone who doesn't mind a little assembly work to put one of these together and have it good to go for any software made with it in mind, or retrogames where you don't mind a weird button count. So... what's the pitch on this scroll wheel anyway?

Well for starters, there's the stuff Sakurai got into this morning. Any sort of RPG or text heavy game can use it to quickly scroll through menu options, or stuff in a text-heavy game. You could also pan the screen with it, something a lot of early 16-bit games assigned to the shoulder buttons or holding up and down while getting used to the new options the hardware was giving them.

Past that, you'll notice in my design it's at a 45 degree angle. I might have to tweak it a little, but my thinking is for a game that uses it heavily, one thumb or the other can slide over easily enough (I'm going for a pretty compact overall design) so we can have some games where you take your thumb off the D-pad, and have this nice analogue steering wheel. Nice for fine control in a racing game, or if you want some little radio-tuning/safe-cracking sorta deal.

Alternatively, move your right thumb over, use the D-pad to steer, shoot and dodge or whatever with shoulder buttons, and use the wheel to rotate a turret for a twin-stick sort of game maybe.

Or just use it for the sort of stuff mouse based games stick on the scrollwheel. Changing weapons, changing powerups... I'm planning to officially label the directions "hot" and "cold" to encourage weird gimmicky things like... I dunno, a platformer where you have a thermostat in your controller you can always mess with, freeze water coming out of pipes, crank up flame jets? Have a shot charging mechanic where you just really crank it to get to max strength? Weird minigame stuff. There's some fun space to explore with it.

Then we have the rest of the design here... which basically comes down to me being just plain sick of how every controller made by anyone in the past... 20 years give or take has kind of the exact same layout? 4 good face buttons, a D-pad, 4 shoulder buttons, 2 sticks, and 1-4 annoying to reach tiny awkward middle buttons, and we're just kind of overdue for a change-up?

Like first of all, hey, this is just too many buttons. There's a ton of games that really only need a D-pad, and maybe 3 buttons (attack jump pause) and the two things that aren't fully standardized is how awkwardly placed the D-pad is and how awful and awkwardly placed the pause button is. Shoulder buttons can be nice, but I've never really felt like 4 of them awkwardly crammed on the rim has been really useful or ergonomic, and that's coming from someone who's been playing a ton of FF14, which gets more use out of them than anything else I could name. And really, aside from games doing fake twin-stick stuff and using the whole grid like a second D-pad, I'm having a really hard time thinking of any game I've ever played that really makes good use of 4 good face buttons? Like people will use them if they've got'em sure, but unless you do that keyboard style thing where you lay the controller on a table and use all your fingers, you can really only comfortably hit 2 face buttons without sliding your thumb away from them, maybe comfortably make a quick pivot to a third.

Also, really, a lot of designers just sort of feel compelled to map SOMETHING to every button, even if it's clear the design didn't really need them. So basically I figure I'll try kinda just taking a "less is more" approach here. Here's the buttons that it's comfortable to rest your thumbs and fingers on, here's a dedicated pause/menu button where people often stick a kind of redundant menu button, here's my gimmicky scrollwheel. That's it, work around that.

I'm also going a little Gamecube inspired (literally using replacement membranes for one in my prototype design, even). Gonna make a great big primary button and use different shapes for the other two. Trying to label these in a less arbitrary fashion than most. If shooting a gun is a thing you do in this game, and there isn't a real good reason not to, default it to this nice right trigger you can hold down all the time. If we're advancing through menus or jumping or holding down gas in a car, here's the big GO button. Need brakes, need to break stuff with a melee attack? Go back in a menu system? There's your other face button. Have a quick dash move or a run you hold down, let's just use the other shoulder.

So yeah. That's my controller. Need to work out the kinks on the scroll wheel, source a cord, and hopefully I can slap things together and this will be something you can just order bits for piecemeal and put together for like, $5-10 after shipping? Maybe less? The parts are shockingly cheap so far.

But yeah if anyone has any insight to the scroll wheel or cord issues, let me know. Also the whole thing is presently a tad back-burnered because I am in a serious financial crisis and I don't want to have electronics spread all over my table if I have to abruptly find a new place to live if I can't scrape next month's rent together. So as usual, donations are incredibly welcome.

PCB de base de cobre, PCB de base de cobre – Hitech Circuits Co., Limited

PCB de alumínio são PCB de substrato de metal isolado comum (IMSPCB) amplamente usados para luzes LED, iluminação automóvel e outras aplicações de alta condutividade térmica. A condutividade t érmica dos PCB de alumínio é geralmente 1W/mK ou 2W/mK. Se a condutividade térmica de um PCB de alumínio não pode satisfazer seus requisitos de aplicação esperados, por que não considerar PCB baseados em cobre?

Os PCB de base de cobre têm melhor condutividade térmica do que os PCB de alumínio e lhes proporcionam muito mais possibilidades de design.

Um PCB de base de cobre é um PCB de núcleo de metal com um substrato de cobre. Se um PCB híbrido cujo substrato é uma placa de cobre dentro da placa FR4, também é uma base de cobre PCB.

Normalmente, os PCB de base de cobre têm a mesma estrutura que os PCB de alumínio - uma camada, duas camadas com um lado de montagem de componentes, duas camadas com dois lados de montagem de componentes, e quatro camadas com dois lados de montagem de componentes. Mesmo eles usam o mesmo material prepreg para isolar as camadas de cobre. No entanto, o substrato de cobre (398W/mK) tem melhor condutividade térmica do que o substrato de alumínio (237W/mK).

What's more, there's thermoelectric separation technology (also called direct touch technology) for copper-base PCBs. Significa que, através da abertura de máscara de soldado e eletroplatagem de cobre para aumentar a espessura de cobre das posições necessárias, o calor conduz diretamente dos LED ou outros componentes para a base de cobre, enquanto a rede de circuitos é independente da rede térmica.

Se você tem uma pesquisa sobre PCB de núcleo metal, por favor contacte-nos livremente, obrigado.

Upload your BOM file and get a Full Turnkey, PCB, or PCB Assembly price for components, labor and bare boards; it’s that simple. Our team of procurement specialists scours their sources to locate the exact parts you’re looking for, at the best price available on any given day.

The Benefits of Turnkey PCB Assembly Manufacturing

The most obvious benefit of turnkey PCB assembly is that businesses don’t have to take their focus off critical processes like continual innovation to spend time figuring out the assembly side. There’s no need to expend time and energy finding the best component costs, going through a frustrating process of procurement and then needing an in-house team to assemble them skillfully. The most significant benefits of turnkey assembly include:

Shorter production time

As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey PCB assembly, however, is a highly-efficient form of electronic assembly. As soon as full-turnkey PCB assembly is determined, an overall assembly quotation and indispensible issues prohibiting smooth manufacturing will be raised so that three times of communication have been cut to one time with electronic assembly efficiency dramatically improved.

Cost effective

With a turnkey contract, there is no extra cost to deliver freight to an assembly workshop, meaning you save a significant amount of money. Turnkey services also have good working relationships with component manufacturers and can almost always get a better price for parts than small or medium businesses.

Issue Identification

A major time and money-saving advantage of turnkey PCB assembly is the ability to spot potential issues before the circuit boards make it into any products. As part of the process, you submit a netlist file to the assembler. Before assembly begins, the assembler will check to be sure specifications match the application and identify any errors that may be present. Should any errors be found, you have the opportunity to correct the design and avoid being saddled with thousands of unsuitable circuit boards.

Streamlined Management

Dealing with multiple vendors can be stressful and a time drain, especially on small businesses with fewer human resources to go around. With turnkey manufacturing solutions, you stand a far less chance of experiencing a miscommunication because you’re managing multiple channels of interaction. These potential miscommunications can happen between you and a vendor, or even between vendors, and can lead to derailment of your timeline and wasted money.

Your turnkey supplier will likely provide you with a single point of contact through which all business will be conducted, providing you with peace of mind and lightening the burden of management in the assembly of PCBs.

How to obtain a quote for your turnkey pcb electronics ?

PCB Online Quote: An Instant PCB price can be quoted base on Board information. Full turnkey assembly cost: This is an additional instant quote for the cost of labor for Turnkey PCB assembly. BOM Pricing: To get a BOM price within 24 hours, email the BOM to [email protected] and include all details such as quantities, reference designators, and Parts manufacturer name and part number. Most entrepreneurs and manufacturers find the old ways of manufacturing electronics and to printed circuit board assembly very intimidating because it is slow, prone to errors, and expensive. It wasn’t designed for small batch runs and prototypes, but to support enormous orders with a long lead time. Luckily, the services of Turnkey Printed Circuit Board (PCB) assembly are coming in today to meet the needs of hardware designers

Precautions during Turnkey PCBA processing

PCBA is the abbreviation of Printed Circuit Board Assembly, which is an important link in the manufacturing process of electronic equipment. In the process of PCBA processing and production, there are some precautions that need special attention to ensure product quality and production efficiency. This article will introduce the matters needing attention in the PCBA processing and production process from the perspective of PCBA processing and production process.

1. Design stage

In the process of PCBA processing and production, the design stage is very important. In the design stage, it is necessary to consider the layout of the PCB circuit board, the selection and layout of components, the direction of the circuit and the connection method, etc. The following points need to be paid attention to during the design phase:

(1) Component selection: Selecting the appropriate components is an important guarantee to ensure the quality of the circuit board. When selecting components, you need to pay attention to the brand, model, package and parameters of the components to ensure the quality and stability of the components.

(2) Design of PCB circuit board: The design of PCB circuit board needs to consider the size, layout, line direction and connection mode of components, etc. Certain layout rules need to be followed during design to avoid interference between components and ensure the stability and reliability of the circuit board.

(3) Anti-static: During the design and manufacture of PCB circuit boards, attention should be paid to prevent static electricity interference. During operation, anti-static measures such as anti-static gloves and static mats should be used to avoid damage to components.

2. Manufacturing stage

In the manufacturing stage of the PCBA processing production process, the following points need to be paid attention to:

(1) Manufacture of PCB circuit board: The manufacture of PCB circuit board needs to pay attention to ensure the smoothness and flatness of the board surface, so as to avoid the unevenness of the board surface and cause the components to be welded weakly.

(2) Mounting of components: The placement of components needs to ensure that the position and posture of the components are accurate, and avoid damage or functional failure of the circuit board due to deviations in position or posture.

(3) Soldering process: During the welding process, it is necessary to pay attention to the control of temperature and time to avoid damage to components caused by excessive welding temperature or too long time.

(4) Quality inspection: In the process of PCBA processing and production, quality inspection is required, including the welding quality of components and the connection quality of lines, etc. In the testing process, it is necessary to use professional testing instruments and equipment to ensure the quality and reliability of the product.

3. Encapsulation stage

In the packaging stage of PCBA processing and production process, the following points need to be paid attention to:

(1) Selection of packaging materials: The selection of packaging materials needs to be determined according to the performance requirements of the product and the use environment, such as high temperature resistance, heat resistance, dust resistance, etc.

(2) Temperature and time control during the packaging process: During the packaging process, it is necessary to pay attention to the control of temperature and time, so as to avoid the failure of packaging materials or the degradation of product performance due to excessive temperature or too long time.

(3) The sealing of the package: the sealing of the package is very important to the stability and reliability of the product, and it is necessary to ensure the sealing during the packaging process.

4. Testing phase

In the testing phase of the PCBA processing and production process, the following points need to be paid attention to:

(1) Selection of testing instruments and equipment: The selection of testing instruments and equipment needs to be determined according to the performance and specifications of the product to ensure the accuracy and reliability of the test results.

(2) Setting of test parameters: The setting of test parameters needs to be determined according to the performance requirements and specifications of the product to ensure the accuracy and reliability of the test results.

(3) Judgment and recording of test results: The judgment and recording of test results need to be carried out in strict accordance with product testing standards to ensure the accuracy and reliability of test results.

Briefly, in the PCBA processing and production process, we need to pay attention to the details of each link, so as to ensure the quality and reliability of the product. In the manufacturing process, it is necessary to strictly follow the design requirements and manufacturing standards, follow good manufacturing specifications and quality management systems, and finally achieve high-quality, high-efficiency PCBA processing and production.

Common machines for Turnkey SMT processing

1. SMT machine: It is used to accurately place the components on the PCB, including automatic surface mounting machines, semi-automatic surface mounting machines and manual mounting machines.

2. Hot air soldering equipment: including hot air guns and reflow soldering ovens etc., it used to solder SMT components on PCBs.

3. SMT component storage rack: used to store and organize SMT components.

4. 3D AOI inspection equipment: used to check the placement and quality of SMT components.

5. Coating equipment: including automatic coating machine and manual coating machine, etc., used to coat the glue on the surface of PCB.

6. Solder paste printing machine: used to print solder paste on PCB for use in subsequent soldering process.

7. Wave soldering equipment: used for soldering DIP components, such as connectors, sockets, etc.

8. Cutting machine: used to cut the PCB after patch into a single board.

9. Cleaning equipment: used to clean the PCB after assembly, and remove the residual glue and solder paste.

The above are some equipment commonly used in SMT assembly processing, but which equipment and tools need to be used shall be determined according to the actual situation and process requirements.

Common inspection methods for Turnkey PCB Assembly processing

Our testing and inspection equipment are suitable for simple as well as complex PCB assembly requirements. We can take on extremely demanding projects, and ensure high quality product yield.

1. Optical inspection method

With the reduction of package size for SMT components and the increase the density for PCB assembly, SMA inspection is becoming more and more difficult, and manual visual inspection is insufficient now, and its stability and reliability are difficult to meet the needs in our production and quality control, so the use of optical inspection is becoming more and more important.

2. Artificial visual inspection method

This method requires less investment and does not require the programs, but it’s slowly and required directly visual inspect the tested area. Due to the shortcomings of visual inspection, it is rarely used as the mainly quality inspection method in the SMT production line, but most of them are used for repair and rework.

3. AOI method

Using automated optical inspection as a defect reduction tool, it can be used to find and eliminate errors early in the SMT process for good quality control. AOI adopted advanced vision system, new lighting method, high magnification and complex processing method, so as to obtain high defect capture rate at high test speed.

Turnkey PCB Assembly Rework & Repair Guidelines

PCBA Boards can be reworked and repaired. However, only reasonable operations based on scientific guidelines can guarantee the quality of PCBA boards;

1. PCBA rework and repair basis

Rework and repair of PCBA must be performed in accordance with PCB design documents and repair regulations, and there also must be a unified rework and repair process.

2. The rework times allowed for each solder joint

Rework is allowed for defective solder joints, and rework for each solder joint shall not exceed three times, otherwise it will cause damage to the solder joints.

3. Use of removed components

In principle, the disassembled components should not be used anymore. If they need to be used, they must be screened and tested according to the original electrical performance and process performance of the components, and the installation is allowed only when they meet the requirements.

4. Times of desoldering on each pad

Each printed pad should be desoldered only once (that is, only one component is allowed to be replaced). The thickness of the intermetallic compound (IMC) of a qualified solder joint is 1.5～3.5μm, and the thickness will increase after remelting, even when it reaches 50µm, the solder joint becomes brittle, the solder strength decreases... As a result, there are serious reliability risks under vibration conditions.

5. Bow and twist requirements for surface mounting and mixed mounting PCBA assembly and soldering

The bow and twist of surface mounting and mixed mounting PCBA assembly and welding are less than 0.75%.

6. Total times of PCB assembly repairs

The total times of repairs for PCB assembly is limited to six; In other words, excessive repairs and modifications affect PCBA reliability.

Production requirements for Turnkey PCB Assembly processing

1. The production line is set up reasonably and all the labels are correctly posted, warehouse materials and parts should be stored in categories and stacked neatly.

2. Product batch management: The defective product control procedure should clearly stipulate the isolation, identification, recording, review and treatment for these defectives. Typically, there should be no more than three times rework for product and no more than twice for component reworks.

3. Civilized production: clean, no debris, civilized operation, no brutal and disorderly operation. On-site management must have rules and regulations, inspections, evaluations and records, and carry out "6S" activities every day.

4. The maintenance for SMT production line machine and equipment: key equipment should be regularly inspected by special staff, to keep the machine in good condition at all times, we also need to track and monitor the equipment status, and if find problems for machines, we need to take correct solutions to fix and repair it in time.

build a keyboard

₊˚ ᗢ modern au! alhaitham x gn! reader.

⤷ a headcanon involving keyboards.

alhaitham is the type to build his own keyboard. it started with small minor adjustments to his old keyboard, swapping out the switches for softer ones. little by little, it grew until he spent enough of his money for this to become a full-blown hobby.

kaveh was unimpressed by this hobby at first. he does not see the appeal in having a keyboard that simply “feels” better. he’s grown used to the flat keys of his laptop and as alhaitham said: “his ears must have gone deaf if he could not tell the difference between these two keyboards.”

he’s a very minimalistic person, his favorite keyboard is the neo70. its simplistic, easy to build, highly customizable, and in his book, more budget-friendly than other keyboards he’s built. he adores the meticulous work of lubing each switch and snapping together stabilizers. with a little music, it keeps him busy and calm throughout the day.

he prefers to have silent or tactile switches. he finds the loud, obnoxious clacking to be distracting and stressful. this is why he doesn’t want to help kaveh build his keyboard. as the blond prefers the louder, clacky keys that cause alhaitham’s eyes to twitch a little in annoyance. not to mention, he’s impatient. kaveh presses his switches too hard into the pcb which ends up bending his pins.

when you are together, on occasion, he will ask you to build a keyboard with you. if you’re not all into it, then he doesn’t mind. but if you are, he’ll be more than happy to share with you some of his favorite switches. his love language to you would be lubing them for you.

he’ll remember all your favorite colors and materials. if you prefer a beige or neutral-colored board, he’s got you covered. and if you give him an abstract concept to turn into a keyboard, he would do that as well. as a joke, you once told him to build you a sushi-themed keyboard. you did not specify what kind of fish but he was quick to show you his completed board: a dark green case with a nicepbt nigiri keycap set.

you are the only person allowed to touch his keyboards, on the condition that you have clean hands of course. and if you would let him, he would build you one of his favorites. when he sees it on your desk, his heart beats a little faster than it was before. a small gesture that you’ve accepted his absurd yet endearing hobby.

“ah, you put your stabilizers wrong, let me help you,” leaning over you, he pops them out to fix their position. he gives you a short kiss on your forehead when it is finished. “this is where it should be.”

⤷ notes; might be a little self-indulgent. i also have a neo70 and its my first "budget" keyboard. its a really pretty board but i plan on replacing it with the zoom65v3.

Review: Armaggeddon MKO-13R keyboard (1 year)

The MKO-13R is a wired full-size (100%) RGB gaming keyboard with optical switches (and full N-key rollover) by Armaggeddon. The case is low-profile with floating keycaps, and the top panel is metal. It comes prebuilt with Outemu optical switches and top-printed shine-through keycaps.

In the box: 1 keyboard, 1 plastic keycap puller, 1 switch puller, 3 replacement switches.

Hot-swap: The keyboard is hot-swappable, but I wouldn't recommend using the switch puller that came with the keyboard. A longer, plier-like switch puller with a good grip would give you better leverage, which you would need because these switches are a pita to remove. Some of them popped out without too much trouble, but as previously mentioned most were pain and required either a bit of force or quite a bit of fiddling. I recently replaced all of the clicky Outemu blue switches with tactile Outemu brown switches and they work as intended.

Switch compatibility: It's compatible with Gateron optical switches and, of course, other Outemu optical switches. I haven't tried other brands.

RGB: RGB lighting can be customised for each key separately, whether through a proprietary software or very patient use of key presses. It comes with some preset backlighting effects that are pretty neat as well, though I've never used them because (1) I'm not a gamer and (2) I find them quite distracting.

Durability: The RGB isn't particularly durable. After about a year or so, I noticed that some colours failed on a couple of keys, so what should've been white turned into yellow, and what should've been yellow turned into red. Ever since, I've disabled RGB. The print on the keycaps was too low-contrast relative to the base colour of the keycaps (mine is the black version) when it's not backlit, so I ended up getting non-shine-through keycaps with high contrast prints

Would I recommend this? Well, I got it for about 70 SGD and it's still working over a year in, while a membrane keyboard I got for 15 SGD lasted all of a month before starting to chatter, so I'd say it's not a bad deal. I expect that it'll last quite a while, PCB-allowing, especially since the switches can be replaced if they die and there's no risk of wearing out hot-swap sockets since these optical switches don't even seem to contact the PCB. As for the N-key rollover...as a non-gamer this is a non-issue for me and I've never tested it. Sorry. :(
