The B1 sample is finished. The wiper motor had an overheat defect, therefore a new 250W motor is used. Wich, suprisingly, costs the same. Because of the new motor dimesions the hole machine design needs to be changed, but testings have been promising...
By chance I found another post about this dcdc converter with in-depth measurements. Check it out here: https://lygte-info.dk/review/Converter DC-DC 10A 8.5-48V to 10-50V 250W UK.html
I recently updated the system to use a geared DC motor with an encoder for controlling the pencil movements. This approach is looking promising to solve the pencil position tracking issue and speed limitations I was having with the previous stepper motor...
for tuning i followed more or less the tutorial PID Without a PhD from Tim Wescott and the tutorial and video from PID Explained Team. first i just checked with low temperatures of 20..40°C as i went on and tested up to 260°C i noticed that...
By using precise scientific approach and materials (i.e. a bit of foam board and a few nails) I "designed" a mechanical linkage which can move between two required positions. Based on that I added a bunch of holes in the keyboard case and a few holes...
One it was clear that I needed a custom step-up charge controller for my solar car project, I needed to plan out the design. Let’s address the MUST HAVE requirements first: Output voltage regulation is one important safeguard against overcharging the...
Enclosure and thermal images Now it is placed in the enclosure: With the closed enclosure the inverter has been tested at load 250W for temperature rise. Here are some thermal images after 2 hours:
