Servo tester - tester of servomechanisms

cults3d

Purpose: to have a small, portable, autonomous servo tester,...to determine the "neutral" position of the servo(s), to check the direction of the movements and their amplitude, to correctly position the rudder in the final assembly of the servo, etc... Purchasing: electronic and mechanical components as per list Tester: https://fr.aliexpress.com/item/32828837370.html?spm=a2g0s.9042311.0.0.27426c37wxOl8S Battery holder 18650: https://fr.aliexpress.com/item/4000032554751.html?spm=a2g0o.productlist.0.0.7e62454aVTTfp7&algo_pvid=54654def-2537-488e-b16e-ddd07b24c721&algo_expid=54654def-2537-488e-b16e-ddd07b24c721-2&btsid=4cc9d29c-b853-4e22-92dd-7a8b104d147d&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Battery 18650 (4 pcs): https://fr.aliexpress.com/item/4000015991106.html?spm=a2g0o.productlist.0.0.7e62454aVTTfp7&algo_pvid=329d7d90-ce16-40cd-a027-bb62639381f5&algo_expid=329d7d90-ce16-40cd-a027-bb62639381f5-13&btsid=51a2c2bd-af40-4b69-b2f9-29bfbc35c5cf&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Charger module: https://fr.aliexpress.com/item/4000156315289.html?spm=a2g0o.productlist.0.0.6a2b20e04smTcV&algo_pvid=4b2336f0-0b80-4a81-9b12-1dc12667cdc4&algo_expid=4b2336f0-0b80-4a81-9b12-1dc12667cdc4-14&btsid=cfb4bbae-e8c8-4116-8b6e-980556d1a7a7&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Step-up DC-DC: https://fr.aliexpress.com/item/32366166138.html?spm=a2g0o.productlist.0.0.6fdf5eb0fhUGeR&algo_pvid=81c1bab1-425e-4289-af5f-003cc56bfdea&algo_expid=81c1bab1-425e-4289-af5f-003cc56bfdea-3&btsid=c8665a1c-3537-407e-8f11-4453c28f7220&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Step-up 5V: https://fr.aliexpress.com/item/4000267031782.html?spm=a2g0o.productlist.0.0.2d828fcfZ0q61W&algo_pvid=4b7c1c1c-31c2-4c48-b9db-57b3ae316759&algo_expid=4b7c1c1c-31c2-4c48-b9db-57b3ae316759-12&btsid=5f86bdbe-2138-4411-a33b-226ac7c7ef40&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Self-tapping screws M1.4x3 mm (100 pitches): https://fr.aliexpress.com/item/33035662138.html?spm=a2g0o.productlist.0.0.777cc364rowmgC&algo_pvid=010fc466-2a9a-49ed-8db8-e1424913d382&algo_expid=010fc466-2a9a-49ed-8db8-e1424913d382-0&btsid=eb506142-8cec-4ede-be4b-44ea49bab9ff&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Prototype printed circuit board 2x8 cm (5 steps): https://fr.aliexpress.com/item/32841431655.html?spm=a2g0o.productlist.0.0.546fdcc3H7k3UG&algo_pvid=fa26b7a6-c911-47a9-a2b7-9f9500a5cda6&algo_expid=fa26b7a6-c911-47a9-a2b7-9f9500a5cda6-1&btsid=cd7f61ab-ed85-49b4-acc9-478d49bdd373&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_55 Pictures: main housing - 3D printing with black metallic Arianeplast filament, cover - 3D printing with the black metallic filament of Arianeplast, in function, access to the charging socket, yes, the battery needs to be recharged from time to time ;) indicator light during charging, indicator light at the end of the charge, the heart of the thing - the "half" of the tester, the battery in its holder, the electronics soldered on a prototype PCB, on/off switch, double layer of self-adhesive foam to "press" the tester against the case once the electronics are screwed in, what is left of the tester (the 4 screws are hidden under the blue label, careful removal!), some components, and 10. all in place "before closing";) The 6 screws for the assembly (4 for the electronics + 2 for the cover) are M2x8mm. ...and for those who are afraid of warping...I propose the main case with the "pads" that have to be removed (important precision) after printing ;)
