CRUMB

Can’t plug power supply, no tutorials how to use it

Great app but no updates or fixes in over a year

It's an amazing idea overall, but as a professional trying to test circuits on the go or without blowing components up accidentally there's no way to make useful circuits that translate to real life. Aside from lacking basic beginner tools like op amps and arduino, the math just doesn't add up. The potential in this app is amazing but if the calculations in the app don't match the ones on my board or notes then it doesn't really work as a tool. Beginners beware...

I love the app but please fix these bugs. I’ve rated this low to get the attention of the developer. Otherwise, it’s a great app. 1. Component images do not rotate making it difficult to tell if the logic has switched. 2. The power rails are backwards related to real life breadboards. 3. Program counters (74HC161) do not reset to 0 on a reset signal, despite the claim of the data sheet. 4. 74HC245 enable pin should be labeled active low but it’s not. 5. EEPROM sometimes corrupts the data saved in the HEX editor. Usually it resets an address to 00. Technically, a cleared EEPROM should have all addresses set to 01 by default (not a big deal but this is what’s technically correct). 6. Many components, most commonly the transistor, lock their image in place even if deleted. It takes resetting the App to make the image go away, even when starting a new file. 7. Usually when in Interact mode, buttons and switches will react to touching the screen even when not touching the component location. This is very frustrating causes a lot of problems, especially with buttons that remain depressed when the user can’t tell, which really messes with logical interactions and troubleshooting. I love this app. However, I would really like these issues fixed. If they do I will rate this app at least 4 stars. 5 stars can be achieved if somehow you can make the app perform better with more components. I understand the admitted limitations but even adjusting settings to the highest performance does not help. There is so much default space in the app but it’s not possible to use all of this space considering the app (and desktop application) crashes once too many components are placed. I can’t help but feel like there must be a way to make this app perform better if so much space is made available. Ideally I would like to be able to replicate the 8 bit CPU project tutorial by Ben Eater. This app has all of the components but unfortunately does not have the memory capacity.

I think the idea is very good, but implementation is bad. Making it 3d feels unnecessary and actually makes it difficult to place parts. Once on the breadboard, moving them seems impossible. I am repositioning everything but the part I want to move. Ultimately I spent 30 minutes placing like three pieces and eventually gave up. I understand this is an ambitious project, and using the unity engine imposes various constraints. That’s all understandable, but I think this app at least currently is a poor choice for rapid prototyping. I have no idea what other reviewers are doing, but working with basic electronic components and wires to connect things is just difficult and slow. I want a rapid prototyping app and this just isn’t it. It is a shame too, because it seems quite capable.

1. I would like to have arduino and other microcontrollers. 1 1/2. I would like to have a spot to code arduino and other microcontrollers. 2. I would like to have it so that you can color the wires a custom color. 3. I would like to be able to create circuit boards with custom and pre-set colors, and put my own electronics on them. 3 1/2. I would like to be able to have pre made circuit boards. 4. I would like to be able to, for example, make a circuit on a bread board, and then press a button and label my circuit, and make that circuit an electronic component. 5. Last but not least, When trying to create a wire using “corner to corner” mode, I would like it if you tapped on any hole on a bread board or power rail, then it would connect to that hole. Thanks for reading my review & please implement everything I said! 👋

needs op amp title says all -Z.M.A.

I always wanted an app like this so Thank you so much to the developers working on this I know it’s still not finished & still under development but I’m still giving it ⭐️⭐️⭐️⭐️⭐️ because I know it will be amazing 👌🏼

Need an ociloscope Signal generator BJT transistors

I was able to place a dip switch. I tried to change the selections on it, but not intuitive if there is a way. I tried a refund. No bueno. I guess my only ability to have issue is to leave this unfortunate review.
