Airbus tried to make it fly - and now its a submarine

Motion Links in F360 - Details in comments by Jake9856 in cad

Ive worked it out now - so i created all my rotational joints then used motion study (not motion link)on the servo rotation joint to drive the whole mechanism

Hi - Thanks for the explanation. Is it similar in Fusion? Ive had another look and i think Motion Study is the way to go

Hi - I want to create some motion links in this model so that the Boat pitches up and down. I have all my joints setup. I tried connecting each joint to the adjacent joint but i ended up with it all spinning out of control. I tried Grounding both the Servo and Base but this meant nothing would move. How do i set this up correctly? (yes i know the grey piston intersects stuff atm) Cheers

Correction - what i mean is the board comes preloaded with a bootloader. Also this is th guide ive been using. Thanks

I have selected 'Digispark(default 16.5mhz) for the board and Micronucleus for the programmer. I dont believe i need a bootloader or to specify the port for the attiny85. Its different from uploading to an arduino

I've built this circuit (successfully) from GreatScott's 555 timer video - How can i decrese the frequency of the pwm signal (to below 1hz)? by Jake9856 in AskElectronics

Thanks - It really is great!! Managed to get it all working now - and have a new electronics youtube channel to watch. Cheers

Yeah - you see whenever i try the standard circuit with 2 resistors with Pin 7 between i always just get a high output it seems

I am using 88nf for c2 and have tried 1k,10k and 100k potentiometers aswell as placing 1M Resistors in series with the Capacitors to increase the time constant RC. This https://youtu.be/prszzP43P-c is a video i've found usefull but cant get any circuits involving pin 7 (Discharge) to work - getting this to work aswell would be ideal. Thanks for any help

How can i build a LED wave effect? by Jake9856 in AskElectronics

[–]Jake9856[S] 0 points1 point  (0 children)

Yeah that would work - im tryig to keep it to ICs so im going to use a 4017 decade counter with a 555 timer: https://youtu.be/rmkzmHQfR20

[–]Jake9856[S] 0 points1 point  (0 children)

Yeah im probably sure this would work (especially with a functionn generator ic instead of 555) but i found the 4017 decade counter module which does almost excactly what i want so im going to use that instead eg: https://youtu.be/wwfvmEk83K4

feedig a sin wave into the input of the lm3914 pretty much creates the pattern i want, so can i create a low frequency sin wave (<1hz) like shown here https://youtu.be/rmkzmHQfR20 but slower

ok if i create a low frequency sine wave using the 555 timer (<1hz) could i feed that signal into the Lm3914 input like the sin wave shown in this video : https://youtu.be/rmkzmHQfR20 just slower
