The battery terminals look like they are for car amplifier power connections.
You could always go to the hardware store and get a threaded cylinder that's hollow, just bring a banana plug with you to match it up.
Hey, I don't have no stinking chip on wy board, damnbit
The cover for the battery terminal would help prevent any accidental shorts.
Hi Julian. Getting back to the remote switch, Banggood do a four relay switch " i think they do a couple of configurations" But the one I brought had a 3 pin header and a shorting link and this allowed momentary, ptm/ptb and also the as one makes the previous one breaks. it cost about 5 1/2 quid, and the part ID is 1012323. The chip number has been scrubbed but on a schematic the number is TIP 224 b or 234 b " the number is not very clear and is a 8 pin smd package ( i know TIP sounds like the TO 220 package. I was thinking of going posh and have my electronics lab lights controlled via remote, then possibly the alarm too; hehe laziness. Paul London
Why not, just for fun, find the volume of the main part and work out its density and see if that matches any non-ferrous alloys?
Those battery terminals are great! They are for car audio.its so you can female terminals for your amplifiers instead of those ring terminals.
you could rig up an add on pcb for the momentary chip, its outputs feeding clocked flip flops such as 74LS74, then back to the main board, that'd give you toggling…
i know exactly what you mean about those chip pullers! 😉 also i'd advise brushing the chip pins with wd40 or silicone oil before inserting , makes them slip in and out much easier 😁
Those old chip pullers have been around since the 60s. I used them in the 70s to pull the UV-EPROM chips from the Incoterm SPD controllers I used to service. Up to eight chips (8KB each) had to be pulled whenever software changes or updates were made. With so many chip insertions "IC Creep" became a problem, so sockets became stronger, but that made the old chip pullers nearly impossible to use. They're really now only good for gripping the chip after you've pried it up with a small screwdriver or placing it onto the socket prior to pushing it down.
I think because your remote is designed for momentary use, it does not have the requisite "all channels off" button.
stanlee is not the same that it use to be, even more since 12/11/18
Even if relay break before make it can draw arc across when current is high enough. Learnt it the hard way._
