This is a post processing script for 3d printing slicers to convert a series of line segments into curves. It fits a series of G1 moves to an arc, then replaces those segments with a single G2 or G3 gcode command. Therefore it only works with 3d printers that support… Continue Reading 3d Printing facet smoothing
I had solar panels installed in September 2018, and have been tweaking a monitoring system for the solar production and my electricity consumption. More details can be found on the github page – HomeMonitoring .
I purchased an inexpensive cnc touch probe many years ago and have always been concerned about the accuracy. These cheap probes (and some expensive ones) use a tripod type arrangement where 3 shafts, spaced 120 degrees apart, rest on pairs of balls. This makes a normally closed circuit, which is… Continue Reading Touch probe accuracy
Introduction New hobby! (yes another). I am in awe of 1:87 micro-modelling. That is taking a 1:87 scale (HO train scale) vehicles and making them radio controlled. Cars, trucks and construction vehicles are the popular conversions. See the YouTube channel Der Theoretiker to see the exciting world of micro-modelling. So instead… Continue Reading STM32 Custom OpenTX Transmitter
I got the Taranis X-Lite to use with DLGs (discuss launch gliders). It is small and light, and a lot cheaper than my DX8, which I was afraid of launching along with my DLG. However it doesn’t have a momentary push button (for launch) and the toggle switches are tiny… Continue Reading Taranis X-Lite Big Switch Upgrade
This is an altimeter that works on the with Spektrum X-bus receivers using a 1s lipo battery. It was designed to be light weight for DLGs (discuss launch gliders). X-Bus is Spektrum’s external interface for telemetry devices – electrically it is I2C. Functionally, the receiver polls all devices once at… Continue Reading 1S X-Bus Altimeter
This is a low voltage alarm for 1s lipo batteries. It was designed to be light weight for DLGs (discuss launch gliders). The schematic is shown below. The schematic is quite simple – a microcontroller, a buzzer and voltage divider to measure the voltage. The microcontroller runs at a low… Continue Reading 1S Low Voltage Monitor
The registration, login, email and hence, comments were not working correctly. That should all be fixed now… Yes, you need to register, and your first post will be moderated.
For a few projects now, I’ve needed closed timing belts of a specific length. Rather than buy them and pay high local prices, or wait for a month for them to be delivered from overseas, I’ve started 3D printing them using nylon. I used nylon to print the flex spline… Continue Reading 3d printed timing belts
If a hypocycloid gearbox is driven quickly, the eccentric driving the cam will cause vibrations. An easy fix for this is to drive 2 cams, mirrored in their action. This means the eccentric, needs to be a dual eccentric… As there are now 2 cams, this means twice as many… Continue Reading 3d printed Hypocycloidic gearboxes IV
