If you would look at my makes on some sites you would see I put some effort in to let the poeple easily understand and redo what I have made. But the maker told, they have had no time to do it better. The documentation had all the wires drawn, went over many pages per book and it was EASY to work with. I can tell you from my professional work I had serviced complex systems much much larger than this piece of …. With lines from starting to endpoint i ean they should not be arrows with names, nets should be drawn from start to end, they could be simplified if there is few space only, with a sing line and a number that tells how many lines are included. This is what a schamatics should tell by design. The reader has to put in a lot og Grips-work to understand how it works. Regarding the usability the drawing is pretty much worthless. Sure I could take some effort in to make it understandable.īut this could be done by the maker in first place. If you’re feeling particularly adventurous, you can always abandon the electric motor and spin it up with a tiny turbine. On the other hand, if you’re willing to buy a cheap rotary tool just to crack it open and replace the electronics, you might as well just build your own. ![]() But hacker beware, the current version of the PCB doesn’t have any AC isolation you’ll need to take special care if you want to hook it up to your computer’s USB port. says that conceptually this should work on any AC brushed motor, and the source code for the firmware is open if you need to make any tweaks. The microprocessor controlled upgrade board uses back EMF to detect the motor’s current speed without the need for any additional sensors important for a retrofit module like this. You could possibly source the latter components from the parts bin, but the potentiometer is likely going to be designed to match the tool so you’ll want that at least. Specifically the potentiometer, filter capacitor, and the motor terminals. But before you chuck it, you’ll need to recover a few key components. Of course, the first step to replacing the speed controller in your not-a-Dremel is removing the crusty old one. While the module design probably won’t work on every clone out there in its current form, he feels confident that with help from the community it could be adapted to other models. So he’s developed a drop-in replacement speed controller for his particular Dremel clone that solves this problem. Recovering components from the original controllerĪs explains, one of the big problems with these clones are the simplistic electronics which have a tendency to stall out the motor at low RPM. There’s only one problem: the similarities between the two are only skin deep. At first glance, they might seem like a perfect solution for the hacker who’s trying to kit out their workshop on a tight budget. They cost just a fraction of the real thing, and even use the same bits as the official Bosch-owned version.
