coinscansmall raspberry pi 3d coin scanner

why a 3d coin scanner? i’ve always been fascinated with coins. the images on coins are often very intricate and the metallic shine makes especially unused coins very beautiful. coin faces are sort of 3d objects compressed into an almost 2d representation with little loss of perceived depth (the coin design process might actually most […]

jet boat jet boat

objective design and build a simple rc jet boat using mostly 3d printed parts. design this is already the fourth design iteration of my rc boat project. the first two worked great in the bath tub. in reality though the jets sucked in air and consequently lost thrust. the third iteration jet works fine but the […]

dakota yellow c-47 dakota, rc plane

historic the douglas dakota is an airplane that is well known in switzerland due to a plane that crash-landed onto gauli glacier in the bernese oberland in 1946. to this day remains of the airplane are occasionally recovered from the glacier. some of them are on display in innertkirchen. the dakota existed in several variants (c-47, […]

webcam raspberry pi webcam

objective online cameras are great. an up-to-date view often helps others in decision making when planning outdoor activities. most commercially available ip cameras are expensive, do not allow full customization, are big and some even require a subscription to access past data. a raspberry pi with camera is a viable alternative. the pre-installed python environment […]

sno explorer sno explorer, tracked rc vehicle

objective design and build a tracked rc vehicle using mostly 3d printed parts. prototype a new law regulating the use of larger rc quadcopters is looming over rc pilots in switzerland. this made me think about how i could reuse larger brushless motors in the future since i have many heavy models that will require some […]

historischer markt aarau 3d coin scanner

objective build a cheap 3d scanner to scan small objects, such as coins, at a very high resolution. scanning principle the scanner projects light onto the surface of an object such that it is partially illuminated. the transition from bright to dark is analyzed and a 3d section of the object is reconstructed via triangulation […]

switzerland european union switzerland – european union gear

objective the intent of the project was to develop an app that creates noncircular gears. the switzerland – european union gear demonstrates what can be done. prototype the prototype of the switzerland – european union gear consists of a 3d printed “swiss gear” and a laser cut internal “european union gear”. for simplicity the gears […]

RCCarSmall_tiny rc car chassis 1:16

objective build a simple 1:16 rc model made of mostly 3d printed parts. design i am not really an rc car driver aficionado but i find it it very interesting to design and build rc cars. my previous rc car project, the 1:6 rc car chassis, took quite a long time to design, build and […]

Bindli_total_smallest quadcopter #11 (micro fpv 150 mm)

a 3d printed quadcopter having an outer shell as its main support structure was the aim when i designed this small quadcopter. its main characteristics are: 150 mm diagonal motor distance 300 g takeoff weight 3″ propellers dys 1306-3100 kv motors dys 10 a blheli esc’s cc3d atom flight controller (running betaflight) frsky tfr6 receiver […]

210_quad_cat_pic quadcopter #10 (210 class)

the 250 quadcopters are great to take along on hikes for filming. but there is still room for further miniaturization without having to bullnose the 5 inch propellers. the 210 class appears to be pretty much the minimum that makes sense. so here is a homemade 210 class quadcopter. the size offers another advantage, at […]
