COnsider a DIY electro-magnet from 5V using 30 AWG magnet wire and iron 20AWG ( twist tie spool in HW store) AWG30 is .39 Ohm/m so for 5V, 5Watt max ,you need 5 Ohms or 12.8m or wire. wrapped around a small bundle of short cut wires taped tightly with mylar or epoxy coated or similar to prevent abrasion or shorting of magnet wire and a loose core
In the 60's we used to make our own Pulse transformers for Zero crossing or Phase control using short soft iron 1mm wires from small spool in hardware store ( like twist in parallel, then mylar or plumber's teflon tape then primary one end , secondary other end using 30 AWG wire or higher. Logic Gate drive current only needs to exceed Triac Gate
As the primary magnetic path is in the core, it is better to have the windings as "flat" as possible. i.e. wind the secondary over the primary with a layer of mylar tape as insulation. Frank
How are you going print white and colour over clear without screen printer. Choose plastic quality avail for DPM membrane switch operation (Polycarb, PVC , mylar etc and reverse ink printing or screening in rolls or cut sheet then cut or stamp to decal size with tooling.
A mercury fluorescent UV tube is most effective with moving film under the light using a slow print feed mechanism. THe tube has no phosphor for converting to daylight. Halogen generates too much heat and will shrink the mylar.
Hello, I thought some folks here may be interested in this web-page trialling a Silhouette Cameo machine... For information on the machine simply google: Silhouette Cameo Or more immediately here is a spec: If you are already a
For the purposes of this is the permativity of mylar? I can find plenty of references to the dielectric strength of mylar with units of kV etc. But I can't find in references to permiativity measured in F/sq m. I am aiming to try my hand at b
I don't see a problem either. There should be no effect in terms of high-speed circuitry. Tape, nail polish, mylar could fix it. I would wait for the next rev to fix it as well.

Hi all I know this is a long post but I tried to put everthing... I am making a bridge rectifier to give DC voltage to another circuit. At the output of the rectifier I am connecting 0.47uF-250V, mylar capacitor and across the capacitor I am connecting resistive load. The bridge should rectify 120 VAC from a WALL OUTLET to obtain a DC voltage.
The datasheet shows a stable mylar capacitor. But the unstable circuit uses a tantalum capacitor that is extremely unstable.
A capacitor only needs a potential difference to charge irrespective of the polarity. All capacitors except electrolytic ones can be charged at any polarity, the electrolytic ones blow up not because of the storage of charge but because of the electrolyte. And so u will always find mylar or ceramic capacitors in diac circuits or any power circuit i
Hi, Some of the capacitors commonly used are as follows: - Air dielectric capacitors, like the ones used in tuning of radio stations. - Paper dielectric capacitors, used in motors to shift the phase. - Plastic film capacitors like polyster, polypropelene, polystyrene,teflon,mylar etc., - Mica capacitors - Ceramic Capacitors - Electrolyt
HI, I'm repairing an electronic device, it has a loudspeaker to change. It seems a mylar speaker. 50mm diameter. there is write on it: 0.2W 50F 50 OHM I found on catalogues similar speaker with same power but i can only find max 22 OHM. Can I use modify this speaker to fit my device?? can i use 22 OHM in your opinion? Where can i Find
