diy – Is it possible to develop cyanotypes with an LCD projector, given the need for UV?

No, there’s no conversion for LCDs — and you wouldn’t have anything approaching the resolution you’d want for a print that size anyway using a digital projector.

The usual procedure for making alternative process prints from digital files is to print a negative on transparency film. It’s the go-to method for cyanotypes, as well as for platinum/palladium and so on, and the results can be indistinguishable from film. The problem here is that you want to go big — really big — and that isn’t going to be cheap.

Methods that print out during exposure need very dense negatives. For that reason, you need a transparency film that can hold rather a lot of ink and produce a good Dmax. The film of choice these days seems to be Pictorico, which is available in 24″ x 66′ rolls. (Do I need to mention that you’ll also need access to a printer that has a carriage width of at least 24″, like the Epson 7X00 series?)

Black ink alone will not provide enough density; you’ll need a secondary UV-blocking ink laid down as well (which means mucking around a bit in your printer settings — or getting your negatives’ printer to muck around a bit in their settings). With Epsons, yellow is a good secondary. You’ll also need a light stochastic noise pattern added to your image’s negative in order to get enough dither for contact printing. As for the printing itself, you can build a UV source, borrow some time at a shop that still does real blueprints or screen printing, or, if all else fails, use the sun. (These exposures are long, and you can inspect them under room light safely to see if they’re cooked yet. Unlike platinum/palladium, the cyanotype prints themselves aren’t so expensive that you can’t afford the learning curve. And the weather people will give you the UV index, which will help gauge the starting time.)

There is a much more in-depth article on creating the negative by Carl Weese at TheOnlinePhotographer.com. The negative you will need for a cyanotype is very similar to the one you’d need for Pt/Pd, and you’ll need to do just as much fiddling around to find the right density and curves. Remember that you can climb the ol’ learning curve using standard-issue letter-sized OHP transparencies; there’s no need to spring for a roll of specialty material until you’re ready to rock. Just make sure that you’re using the same brand and type as the roll. (It’s not something you can pick up at your local business supply depot, but it’s not hard to find online either.)

Do note that you would really need to make a full-sized negative for contact printing no matter how you choose to go about this (unless you can use a modulated scanning high-power UV laser). Using a projector with anything like a reasonable-sized (read “cheap”) negative would mean hours rather than minutes of exposure time, and you won’t be able to tell whether or not the image is in focus until it is partially printed out.

I am new to java, I want to develop my career as software engineer. I am scared that it’s difficult. Please advice me how should I start?

Formally, I was a WordPress developer. I worked over front-end technologies. I know that was an easy task to do. But, I stopped learning new technologies and just passed time with them. Now, I am an enrolled student in Germany for a Master’s. and here, everyone is far ahead in knowledge in the best technologies. Like, Java, Python, DevOps, etc.

For these reasons, I am being honest that I want to also expand my knowledge and want to pursue my career as a software engineer. I have no guidance, I started studying over the w3school website about Java. I am looking for good advice like, how should I overcome this fear that I cannot learn?

I am not a dull person, I work hard, but for the last 3 years, I have had not to learn any language and lost all my confidence. So, I feel that now I am lost, no guidance and nothing. But, software engineering sparks my interest.

Looking for advice and suggestion, how should I start my career.

Many thanks.

Is there a specific language I’ll write in?


A specific client?


A specific IDE?


Where can I get started?

If you don’t wish to create intellectual property rights over your ideas or software, you could start by studying the licences to existing solutions and then study their documentation and source code. If you don’t want to be bound by their licences and want to develop your own intellectual property you’d need to be much more careful and might need to start with a clean-room development process meticulously avoiding any knowledge whatsoever of existing solutions.

❓ASK – How to develop your strategy as an affiliate marketer? | Proxies-free

Affiliate marketing is very lucrative business. There is very minimal risk involved in respect to to other earning platforms like forex trading or any online business, where you have to invest something. Most of the affiliate marketing programs are free and you can start from scratch. You can sell products of the company and earn commissions even from the first day.

Though it is risk free to start in affiliating marketing business but you need to build a proper strategy in order to succeed for long term. It is not like you have sold some units today and and did not try to sell tomorrow. You need to sell products on a daily basis for your earnings to accumulate

That is why a proper strategy is required as to how you will introduce the product to the potential customers and make them potential buyers of your product.

architecture – What is the best way to use Cross Platform (ReactNative/Flutter) to develop BLE application?

TLDR; I’m asking for an opinion of using Cross Platform (ReactNative/Flutter) to develop BLE application

Hi, I’m developing mobile app (iOS & Android) that uses BLE to communicate with IoT Devices. My app is capable of BLE write / indication to exchange data with the IoT

Currently I’m using into React Native (RN) to develop a working prototype. However my experience hasn’t been pleasant. For example, since iOS doesn’t support Mac Address, I need to write a different BLE library extension to write a custom Mac Address in my broadcasted BLE package. The notification BLE also seems to work on the Android, but not on iOS. Moreover I found out that library versioning in React Native sometimes broke my app (e.g. 0.59 to 0.60 RN).

Having said that, I don’t know enough about the current state of the industry for BLE app development. All I want is for my app to be maintainable and stable. So, I was wondering can anyone have recommendations/opinion for using a cross platform like RN or Flutter to develop a BLE app? My experience React Native’s BLE support is pretty rough, and from what I read Flutter BLE support isn’t much better.

More specifically I want an opinion related to:

Is Cross Platform (ReactNative/Flutter) a good idea for developing BLE application?

Does anyone know industry BLE apps that are developed using Cross Platform (ReactNative/Flutter)?

Or would it be actually make more sense to develop a separate native code base for Android and iOS?

For more context, I’m used to write in TypeScript and JS, but don’t have any problem in going for Java/Kotlin or ObjC/Swift. Based on this exerience I thought ReactNative was a perfect fit for me, until it started to not work as stable as I wanted it to be.

Any tips and sharing experience would be great and helpful to me


How to develop a interleaving transition system with 3 parallel programs

Up until now, Ive learnt how to design a transition system using 2 program graphs. But I am looking for researches on this approach with 3 program graphs. I cant seem to find any online resources to help me with this approach.

I have been able to draw out the 3 program graphs separately but am struggling with the interleaving process using the formula

PG($_i$) = ($Loc_i$, $Act_i$, $Effect_i$, →i, $Loc_0$,$_i$, $G_0$,$_i$)

I am struggling with what the interleaved program graph is meant to look like before it is converted into a transition system.

the 3 parallel programs are:


Could someone please point me in the right direction? not necessarily complete the program graph.

unity – What is the platform people use to develop mobile games?

Im a flutter developer. I’ve been trying lately go start developing mobile games, however everyone is saying Unity, and whenever I search for any questions or any error i get in Unity, I find no resources at all. most of the resources that exist are made about 10 years ago.

For someone who wants to build mobile games, which platform is the one commonly used?
