Besides paying for food does the restaurant cost anything? Which area best accommodates 'show and tell'? These are the questions that come to my mind but I will be out of state until the 16th. So my opinion doesn't help. See you next month.

In-Reply-To: References: Message-ID: <05e5bace-a84a-05a8-37f0-4f699e1661ba@undecidedgames.net> Caps can help with ESD, but I'd suggest using purpose-made TVS (Transient Voltage Suppression) devices, which are usually more like diodes than capacitors. Selecting appropriate TVS diodes is a whole deep-dive itself that I readily admit I don't fully understand...I generally go with whatever application notes suggest. A basic rule of thumb is to pick one with a breakdown voltage slightly higher than the positive rail of your power supply, but lower than the maximum input voltages of the components involved. That maximum is often Vdd + 0.5V, but read your datasheets. -B On 12/29/23 11:40, jonathan hunsberger via TriEmbed wrote: > For anyone interested, i hacked something together with EasyEDA that is > at least orderable :)?

In-Reply-To: References: <6F7F9365-F1F5-4402-8180-97241CDA0CB6@gmail.com> Message-ID: My $0.02 on the discussion so far: - Breadboards can have remarkably high internal resistance. Beware when designing impedance-sensitive analog circuits, or when handling high-speed signals, as this combined with parasitic capacitance can really round off your sharp digital corners. - Cutting perfboard down to size is easy with a pair of aircraft shears (aka "tin snips"), so I've never seen that as a particular drawback. - The card-edge tabs are pretty useful but be careful of how much board there is on either side of the pattern; if you're hoping to plug into a card-edge connector, be sure the connector you select allows the width of the board (you may have to have extra contacts, or to trim the board) - PCB design is a really, really deep topic that looks simple on the surface. Go for it! Start simple and learn, learn, learn!

The school hasn't had a Physics teacher for the past few years, and the state of their lab supplies is pretty dismal. Many items belong in the 'antique' category. He's received some money for student supplies for specific labs, but is now working on acquiring more general-purpose equipment. It seems likely that some local business/organization would be willing to donate a relatively inexpensive oscilloscope to the cause, but he has no idea who to approach. Does anyone on the list have suggestions that I could pass along to him? Thanks very much for any info you can provide!

There has been a changeover from CRT to LCD (just like TV's) and there are lots of CRT scopes gathering dust.? Note though that for about $350, you can buy a new LCD scope.? (Rigol, etc.).? I don't know what level of Impoverishment we're talking.? I could spare an analog scope to good home.Sent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: Kevin McClaning via TriEmbed Date: 1/12/24 4:29 PM (GMT-05:00) To: triembed at triembed.org Subject: Re: [TriEmbed] Seeking source for oscilloscope donation to local high school Hi Dawn -- Can you be more specific about the term "new-ish." I have a couple of analog Tektronix scopes that aren't doing anything interesting. I also have a few scopes from the dawn of the digital age, when they were trying to figure out how to do digital oscilloscopes. Mostly 2 channel, 100 MHz sort of scopes. I can't get them to you for a few weeks (traveling). Let me know if they're of interest. Kevin On 1/12/24 12:49, Dawn Trembath via TriEmbed wrote: Hi All! I'm wondering if anyone on this list might know of a potential donor of a new-ish entry-level oscilloscope to a local high school? My son is the new Physics teacher at Hillside High School in Durham.

He's received some money for student supplies for specific labs, but is now working on acquiring more general-purpose equipment.? It seems likely that some local business/organization would be willing to donate a relatively inexpensive oscilloscope to the cause, but he has no idea who to approach. Does anyone on the list have suggestions that I could pass along to him? Thanks very much for any info you can provide!

I've checked in with Stephen regarding a few of the details: Can you be more specific about the term "new-ish." I have a couple of analog Tektronix scopes that aren't doing anything interesting. I suppose 'new-ish' implies that the scope works reliably and is considered safe by today's standards. A lot of the donated equipment that is currently in the supply room is really just e-waste, so the hope was to avoid anything in that category. Currently, there are no oscilloscopes, so anything meeting the above criteria would be useful. One oscilloscope would suffice. Two or three would allow more hands-on experience for the kids. More than three would start to cause storage problems. Note though that for about $350, you can buy a new LCD scope. (Rigol, etc.). I don't know what level of Impoverishment we're talking. Unfortunately, there is a $0 budget for any type of oscilloscope. A new Rigol would be lovely, if anyone happens to know of a business or organization that might be persuaded to donate one. I'll contact everyone who has replied directly to discuss possible donations.
