A fun day in #Bampton with @FraserAntiStat learning about DOE. Obviously, catapults were involved… #Engineering

[Sam Walder @SamDWalder]

A few more boards arrived from @Ragworm , looking forward to populating these. Can you guess what they are?

Simple note to help prevent errors, the pots are upside down so a bit tricky to turn the right way.

More gull photos! Mom and Dad are here to feed the chick!

Pro tip: use a mirror to get to that soldered connection you just can’t reach!

A wonderful distraction from writing: we currently have a baby seagull living on our roof! @UoB_Engineering #urbangulls

[Sam Walder @SamDWalder]

My posts have been a bit infrequent recently, not quite as much excitement in the writing up phase. Here is my progress so far #research #engineering

[Sam Walder @SamDWalder]

The speed with which little bits can be cut with our laser cutter from @TrotecUK means I can get adaptor plates from need to solution in about 30 minutes!

[Sam Walder @SamDWalder]

Working on an automation system for my experimental system saw this nice pile of bits come from @hobbytronics

[Sam Walder @SamDWalder]

I needed to make a coupling fast for an experiment. One of the technicians in @UoB_Engineering came up with this simple solution! #Engineering

[Sam Walder @SamDWalder]

In a pinch you can make a controllable voltage source with a servo hot glued to the knob of a bench power supply (not recommended) @UoBEEES

[Sam Walder @SamDWalder]

Through poor design, isolation requirements, or perhaps paranoia over being able to set a current limit on every voltage rail I have ended up with 16 voltage supply rails in this setup!

A full DPT setup for a prototype of a somewhat odd gate drive concept – time to find out if it is worth committing to a PCB! #MotivationMonday

[Sam Walder @SamDWalder]

I am not sure why the photo did not show up...

[Sam Walder @SamDWalder]

After coming up with a new concept for a gate driver this was the first experimental test. Even the very poor construction was enough to check that this circuit was worth further development. Not suitable as the final thing, but a good start #WednesdayWisdom

[Sam Walder @SamDWalder]

Here is that heatsink in action – two close devises in a tight spot were required to not share the same thermally/electrically connected heatsink. #Engineering

[Sam Walder @SamDWalder]

A sneak peak at a heatsink made for quite a specific testing purpose, can you guess what is going on here? #MotivationMonday

A weekend project saw 5 of us make an espresso martini machine in just 24 hours at the @UoBEEES makeathon https://t.co/c0oR68lW1x

Great to see the success of #DroneDash2 @BristolUni @UoB_Engineering @AirbusCareers @ianrlane1 - super effort from all concerned. Must inspire engineers to address grand challenges our planet faces. https://t.co/VTpit31B2l

[Sam Walder @SamDWalder]

should have been a tag to @Airbus in this! Biggest thanks to them for their support throughout the planning and delivery of this!

Congratulations to “Game of Drones” who won the top prize at the 2nd annual drone dash with @UoBrisRC, @BUILDBristol and the Aero society. All of this was supported by and @BristolUniILO
